INSTALL: converted to markdown => INSTALL.md
Also heavily edited for content. Removed lots of old cruft that we added
like 10+ years ago that is likely incorrect by now.
Also removed INSTALL.devcpp for same reason.

This - document does not describe how to install curl or libcurl using such a - binary package. This document describes how to compile, build and install - curl and libcurl from source code. - -Building from git -================= - - If you get your code off a git repository, see the GIT-INFO file in the - root directory for specific instructions on how to proceed. - -Unix -==== - - A normal Unix installation is made in three or four steps (after you've - unpacked the source archive): - - ./configure - make - make test (optional) - make install - - You probably need to be root when doing the last command. - - If you have checked out the sources from the git repository, read the - GIT-INFO on how to proceed. - - Get a full listing of all available configure options by invoking it like: - - ./configure --help - - If you want to install curl in a different file hierarchy than /usr/local, - you need to specify that already when running configure: - - ./configure --prefix=/path/to/curl/tree - - If you happen to have write permission in that directory, you can do 'make - install' without being root. An example of this would be to make a local - install in your own home directory: - - ./configure --prefix=$HOME - make - make install - - The configure script always tries to find a working SSL library unless - explicitly told not to. If you have OpenSSL installed in the default search - path for your compiler/linker, you don't need to do anything special. If - you have OpenSSL installed in /usr/local/ssl, you can run configure like: - - ./configure --with-ssl - - If you have OpenSSL installed somewhere else (for example, /opt/OpenSSL) - and you have pkg-config installed, set the pkg-config path first, like this: - - env PKG_CONFIG_PATH=/opt/OpenSSL/lib/pkgconfig ./configure --with-ssl - - Without pkg-config installed, use this: - - ./configure --with-ssl=/opt/OpenSSL - - If you insist on forcing a build without SSL support, even though you may - have OpenSSL installed in your system, you can run configure like this: - - ./configure --without-ssl - - If you have OpenSSL installed, but with the libraries in one place and the - header files somewhere else, you have to set the LDFLAGS and CPPFLAGS - environment variables prior to running configure. Something like this - should work: - - (with the Bourne shell and its clones): - - CPPFLAGS="-I/path/to/ssl/include" LDFLAGS="-L/path/to/ssl/lib" \ - ./configure - - (with csh, tcsh and their clones): - - env CPPFLAGS="-I/path/to/ssl/include" LDFLAGS="-L/path/to/ssl/lib" \ - ./configure - - If you have shared SSL libs installed in a directory where your run-time - linker doesn't find them (which usually causes configure failures), you can - provide the -R option to ld on some operating systems to set a hard-coded - path to the run-time linker: - - env LDFLAGS=-R/usr/local/ssl/lib ./configure --with-ssl - - MORE OPTIONS - ------------ - - To force configure to use the standard cc compiler if both cc and gcc are - present, run configure like - - CC=cc ./configure - or - env CC=cc ./configure - - To force a static library compile, disable the shared library creation - by running configure like: - - ./configure --disable-shared - - To tell the configure script to skip searching for thread-safe functions, - add an option like: - - ./configure --disable-thread - - If you're a curl developer and use gcc, you might want to enable more - debug options with the --enable-debug option. - - curl can be built to use a whole range of libraries to provide various - useful services, and configure will try to auto-detect a decent - default. But if you want to alter it, you can select how to deal with - each individual library. - - To build with GnuTLS for SSL/TLS, use both --without-ssl and - --with-gnutls. - - To build with Cyassl for SSL/TLS, use both --without-ssl and - --with-cyassl. - - To build with NSS for SSL/TLS, use both --without-ssl and --with-nss. - - To build with PolarSSL for SSL/TLS, use both --without-ssl and - --with-polarssl. - - To build with axTLS for SSL/TLS, use both --without-ssl and --with-axtls. - - To build with GSS-API support, use --with-gssapi and have the MIT Kerberos - or Heimdal packages installed. - - To get support for SCP and SFTP, build with --with-libssh2 and have - libssh2 0.16 or later installed. - - To get Metalink support, build with --with-libmetalink and have the - libmetalink packages installed. - - SPECIAL CASES - ------------- - - Some versions of uClibc require configuring with CPPFLAGS=-D_GNU_SOURCE=1 - to get correct large file support. - - The Open Watcom C compiler on Linux requires configuring with the variables: - - ./configure CC=owcc AR="$WATCOM/binl/wlib" AR_FLAGS=-q \ - RANLIB=/bin/true STRIP="$WATCOM/binl/wstrip" CFLAGS=-Wextra - -Win32 -===== - - Building Windows DLLs and C run-time (CRT) linkage issues - --------------------------------------------------------- - - As a general rule, building a DLL with static CRT linkage is highly - discouraged, and intermixing CRTs in the same app is something to - avoid at any cost. - - Reading and comprehension of Microsoft Knowledge Base articles - KB94248 and KB140584 is a must for any Windows developer. Especially - important is full understanding if you are not going to follow the - advice given above. - - KB94248 - How To Use the C Run-Time - https://support.microsoft.com/kb/94248/en-us - - KB140584 - How to link with the correct C Run-Time (CRT) library - https://support.microsoft.com/kb/140584/en-us - - KB190799 - Potential Errors Passing CRT Objects Across DLL Boundaries - https://msdn.microsoft.com/en-us/library/ms235460 - - If your app is misbehaving in some strange way, or it is suffering - from memory corruption, before asking for further help, please try - first to rebuild every single library your app uses as well as your - app using the debug multithreaded dynamic C runtime. - - If you get linkage errors read section 5.7 of the FAQ document. - - MingW32 - ------- - - Make sure that MinGW32's bin dir is in the search path, for example: - - set PATH=c:\mingw32\bin;%PATH% - - then run 'mingw32-make mingw32' in the root dir. There are other - make targets available to build libcurl with more features, use: - 'mingw32-make mingw32-zlib' to build with Zlib support; - 'mingw32-make mingw32-ssl-zlib' to build with SSL and Zlib enabled; - 'mingw32-make mingw32-ssh2-ssl-zlib' to build with SSH2, SSL, Zlib; - 'mingw32-make mingw32-ssh2-ssl-sspi-zlib' to build with SSH2, SSL, Zlib - and SSPI support. - - If you have any problems linking libraries or finding header files, be sure - to verify that the provided "Makefile.m32" files use the proper paths, and - adjust as necessary. It is also possible to override these paths with - environment variables, for example: - - set ZLIB_PATH=c:\zlib-1.2.8 - set OPENSSL_PATH=c:\openssl-1.0.2c - set LIBSSH2_PATH=c:\libssh2-1.6.0 - - ATTENTION: if you want to build with libssh2 support you have to use latest - version 0.17 - previous versions will NOT work with 7.17.0 and later! - Use 'mingw32-make mingw32-ssh2-ssl-zlib' to build with SSH2 and SSL enabled. - - It is now also possible to build with other LDAP SDKs than MS LDAP; - currently it is possible to build with native Win32 OpenLDAP, or with the - Novell CLDAP SDK. If you want to use these you need to set these vars: - - set LDAP_SDK=c:\openldap - set USE_LDAP_OPENLDAP=1 - - or for using the Novell SDK: - - set USE_LDAP_NOVELL=1 - - If you want to enable LDAPS support then set LDAPS=1. - - - optional MingW32-built OpenLDAP SDK available from: - http://www.gknw.net/mirror/openldap/ - - optional recent Novell CLDAP SDK available from: - https://www.novell.com/developer/ndk/ldap_libraries_for_c.html - - Cygwin - ------ - - Almost identical to the unix installation. Run the configure script in the - curl root with 'sh configure'. Make sure you have the sh executable in - /bin/ or you'll see the configure fail toward the end. - - Run 'make' - - Dev-Cpp - ------- - - See the separate INSTALL.devcpp file for details. - - MSVC 6 caveats - -------------- - - If you use MSVC 6 it is required that you use the February 2003 edition of - the 'Platform SDK' which can be downloaded from: - - https://www.microsoft.com/en-us/download/details.aspx?id=12261 - - Building any software with MSVC 6 without having PSDK installed is just - asking for trouble down the road once you have released it, you might notice - the problems in the first corner or ten miles ahead, depending mostly on your - choice of static vs dynamic runtime and third party libraries. Anyone using - software built in such way will at some point regret having done so. - - If the compiler has been updated with the installation of a service pack as - those mentioned in https://support.microsoft.com/kb/194022 the compiler can be - safely used to read source code, translate and make it object code. - - But, even with the service packs mentioned above installed, the resulting - software generated in such an environment will be using outdated system - header files and libraries with bugs and security issues which have already - been addressed and fixed long time ago. - - So, building curl and libcurl with MSVC 6 without PSDK is absolutely - discouraged for the benefit of anyone using software built in such - environment. And it will not be supported in any way, as we could just - be hunting bugs which have already been fixed way back in 2003. - - When building with MSVC 6 we attempt to detect if PSDK is not being used, - and if this is the case the build process will fail hard with an error - message stating that the February 2003 PSDK is required. This is done to - protect the unsuspecting and avoid PEBKAC issues. - - Additionally it might happen that a die hard MSVC hacker still wants to - build curl and libcurl with MSVC 6 without PSDK installed, even knowing - that this is a highly discouraged and unsupported build environment. In - this case the brave of heart will be able to build in such an environment - with the requisite of defining preprocessor symbol ALLOW_MSVC6_WITHOUT_PSDK - in lib/config-win32.h and knowing that LDAP and IPv6 support will be missing. - - MSVC from command line - ---------------------- - - Run the 'vcvars32.bat' file to get a proper environment. The - vcvars32.bat file is part of the Microsoft development environment and - you may find it in 'C:\Program Files\Microsoft Visual Studio\vc98\bin' - provided that you installed Visual C/C++ 6 in the default directory. - - Then run 'nmake vc' in curl's root directory. - - If you want to compile with zlib support, you will need to build - zlib (http://www.zlib.net/) as well. Please read the zlib - documentation on how to compile zlib. Define the ZLIB_PATH environment - variable to the location of zlib.h and zlib.lib, for example: - - set ZLIB_PATH=c:\zlib-1.2.8 - - Then run 'nmake vc-zlib' in curl's root directory. - - If you want to compile with SSL support you need the OpenSSL package. - Please read the OpenSSL documentation on how to compile and install - the OpenSSL libraries. The build process of OpenSSL generates the - libeay32.dll and ssleay32.dll files in the out32dll subdirectory in - the OpenSSL home directory. OpenSSL static libraries (libeay32.lib, - ssleay32.lib, RSAglue.lib) are created in the out32 subdirectory. - - Before running nmake define the OPENSSL_PATH environment variable with - the root/base directory of OpenSSL, for example: - - set OPENSSL_PATH=c:\openssl-0.9.8zc - - Then run 'nmake vc-ssl' or 'nmake vc-ssl-dll' in curl's root - directory. 'nmake vc-ssl' will create a libcurl static and dynamic - libraries in the lib subdirectory, as well as a statically linked - version of curl.exe in the src subdirectory. This statically linked - version is a standalone executable not requiring any DLL at - runtime. This make method requires that you have the static OpenSSL - libraries available in OpenSSL's out32 subdirectory. - 'nmake vc-ssl-dll' creates the libcurl dynamic library and - links curl.exe against libcurl and OpenSSL dynamically. - This executable requires libcurl.dll and the OpenSSL DLLs - at runtime. - Run 'nmake vc-ssl-zlib' to build with both ssl and zlib support. - - MSVC IDE - -------- - - A fairly comprehensive set of Visual Studio project files are available for - v6.0 through v12.0 and are located in the projects folder to allow proper - building of both the libcurl library as well as the curl tool. - - For more information about these projects and building via Visual Studio - please see the README file located in the projects folder. - - Borland C++ compiler - -------------------- - - Ensure that your build environment is properly set up to use the compiler - and associated tools. PATH environment variable must include the path to - bin subdirectory of your compiler installation, eg: c:\Borland\BCC55\bin - - It is advisable to set environment variable BCCDIR to the base path of - the compiler installation. - - set BCCDIR=c:\Borland\BCC55 - - In order to build a plain vanilla version of curl and libcurl run the - following command from curl's root directory: - - make borland - - To build curl and libcurl with zlib and OpenSSL support set environment - variables ZLIB_PATH and OPENSSL_PATH to the base subdirectories of the - already built zlib and OpenSSL libraries and from curl's root directory - run command: - - make borland-ssl-zlib - - libcurl library will be built in 'lib' subdirectory while curl tool - is built in 'src' subdirectory. In order to use libcurl library it is - advisable to modify compiler's configuration file bcc32.cfg located - in c:\Borland\BCC55\bin to reflect the location of libraries include - paths for example the '-I' line could result in something like: - - -I"c:\Borland\BCC55\include;c:\curl\include;c:\openssl\inc32" - - bcc3.cfg '-L' line could also be modified to reflect the location of - of libcurl library resulting for example: - - -L"c:\Borland\BCC55\lib;c:\curl\lib;c:\openssl\out32" - - In order to build sample program 'simple.c' from the docs\examples - subdirectory run following command from mentioned subdirectory: - - bcc32 simple.c libcurl.lib cw32mt.lib - - In order to build sample program simplessl.c an SSL enabled libcurl - is required, as well as the OpenSSL libeay32.lib and ssleay32.lib - libraries. - - OTHER MSVC IDEs - --------------- - - If you use VC++, Borland or similar compilers. Include all lib source - files in a static lib "project" (all .c and .h files that is). - (you should name it libcurl or similar) - - Make the sources in the src/ drawer be a "win32 console application" - project. Name it curl. - - Disabling Specific Protocols in Win32 builds - -------------------------------------------- - - The configure utility, unfortunately, is not available for the Windows - environment, therefore, you cannot use the various disable-protocol - options of the configure utility on this platform. - - However, you can use the following defines to disable specific - protocols: - - HTTP_ONLY disables all protocols except HTTP - CURL_DISABLE_FTP disables FTP - CURL_DISABLE_LDAP disables LDAP - CURL_DISABLE_TELNET disables TELNET - CURL_DISABLE_DICT disables DICT - CURL_DISABLE_FILE disables FILE - CURL_DISABLE_TFTP disables TFTP - CURL_DISABLE_HTTP disables HTTP - CURL_DISABLE_IMAP disables IMAP - CURL_DISABLE_POP3 disables POP3 - CURL_DISABLE_SMTP disables SMTP - - If you want to set any of these defines you have the following options: - - - Modify lib/config-win32.h - - Modify lib/curl_setup.h - - Modify lib/Makefile.vc6 - - Modify the "Preprocessor Definitions" in the libcurl project - - Note: The pre-processor settings can be found using the Visual Studio IDE - under "Project -> Settings -> C/C++ -> General" in VC6 and "Project -> - Properties -> Configuration Properties -> C/C++ -> Preprocessor" in later - versions. - - Using BSD-style lwIP instead of Winsock TCP/IP stack in Win32 builds - -------------------------------------------------------------------- - - In order to compile libcurl and curl using BSD-style lwIP TCP/IP stack - it is necessary to make definition of preprocessor symbol USE_LWIPSOCK - visible to libcurl and curl compilation processes. To set this definition - you have the following alternatives: - - - Modify lib/config-win32.h and src/config-win32.h - - Modify lib/Makefile.vc6 - - Modify the "Preprocessor Definitions" in the libcurl project - - Note: The pre-processor settings can be found using the Visual Studio IDE - under "Project -> Settings -> C/C++ -> General" in VC6 and "Project -> - Properties -> Configuration Properties -> C/C++ -> Preprocessor" in later - versions. - - Once that libcurl has been built with BSD-style lwIP TCP/IP stack support, - in order to use it with your program it is mandatory that your program - includes lwIP header file <lwip/opt.h> (or another lwIP header that includes - this) before including any libcurl header. Your program does not need the - USE_LWIPSOCK preprocessor definition which is for libcurl internals only. - - Compilation has been verified with lwIP 1.4.0 and contrib-1.4.0 from: - - http://download.savannah.gnu.org/releases/lwip/lwip-1.4.0.zip - http://download.savannah.gnu.org/releases/lwip/contrib-1.4.0.zip - - This BSD-style lwIP TCP/IP stack support must be considered experimental - given that it has been verified that lwIP 1.4.0 still needs some polish, - and libcurl might yet need some additional adjustment, caveat emptor. - - Important static libcurl usage note - ----------------------------------- - - When building an application that uses the static libcurl library, you must - add '-DCURL_STATICLIB' to your CFLAGS. Otherwise the linker will look for - dynamic import symbols. - - Legacy Windows and SSL - ---------------------- - - WinSSL (specifically SChannel from Windows SSPI), is the native SSL library - in Windows. However, WinSSL in Windows <= XP is unable to connect to servers - that no longer support the legacy handshakes and algorithms used by those - versions. If you will be using curl in one of those earlier versions of - Windows you should choose another SSL backend such as OpenSSL. - -Apple iOS and Mac OS X -====================== - - On recent Apple operating systems, curl can be built to use Apple's - SSL/TLS implementation, Secure Transport, instead of OpenSSL. To build with - Secure Transport for SSL/TLS, use the configure option --with-darwinssl. (It - is not necessary to use the option --without-ssl.) This feature requires iOS - 5.0 or later, or OS X 10.5 ("Leopard") or later. - - When Secure Transport is in use, the curl options --cacert and --capath and - their libcurl equivalents, will be ignored, because Secure Transport uses - the certificates stored in the Keychain to evaluate whether or not to trust - the server. This, of course, includes the root certificates that ship with - the OS. The --cert and --engine options, and their libcurl equivalents, are - currently unimplemented in curl with Secure Transport. - - For OS X users: In OS X 10.8 ("Mountain Lion"), Apple made a major - overhaul to the Secure Transport API that, among other things, added - support for the newer TLS 1.1 and 1.2 protocols. To get curl to support - TLS 1.1 and 1.2, you must build curl on Mountain Lion or later, or by - using the equivalent SDK. If you set the MACOSX_DEPLOYMENT_TARGET - environmental variable to an earlier version of OS X prior to building curl, - then curl will use the new Secure Transport API on Mountain Lion and later, - and fall back on the older API when the same curl binary is executed on - older cats. For example, running these commands in curl's directory in the - shell will build the code such that it will run on cats as old as OS X 10.6 - ("Snow Leopard") (using bash): - - export MACOSX_DEPLOYMENT_TARGET="10.6" - ./configure --with-darwinssl - make - -IBM OS/2 -======== - - Building under OS/2 is not much different from building under unix. - You need: - - - emx 0.9d - - GNU make - - GNU patch - - ksh - - GNU bison - - GNU file utilities - - GNU sed - - autoconf 2.13 - - If you want to build with OpenSSL or OpenLDAP support, you'll need to - download those libraries, too. Dirk Ohme has done some work to port SSL - libraries under OS/2, but it looks like he doesn't care about emx. You'll - find his patches on: http://come.to/Dirk_Ohme - - If during the linking you get an error about _errno being an undefined - symbol referenced from the text segment, you need to add -D__ST_MT_ERRNO__ - in your definitions. - - If everything seems to work fine but there's no curl.exe, you need to add - -Zexe to your linker flags. - - If you're getting huge binaries, probably your makefiles have the -g in - CFLAGS. - -VMS -=== - - (The VMS section is in whole contributed by the friendly Nico Baggus) - - Curl seems to work with FTP & HTTP other protocols are not tested. (the - perl http/ftp testing server supplied as testing too cannot work on VMS - because vms has no concept of fork(). [ I tried to give it a whack, but - that's of no use. - - SSL stuff has not been ported. - - Telnet has about the same issues as for Win32. When the changes for Win32 - are clear maybe they'll work for VMS too. The basic problem is that select - ONLY works for sockets. - - Marked instances of fopen/[f]stat that might become a problem, especially - for non stream files. In this regard, the files opened for writing will be - created stream/lf and will thus be safe. Just keep in mind that non-binary - read/wring from/to files will have a records size limit of 32767 bytes - imposed. - - Stat to get the size of the files is again only safe for stream files & - fixed record files without implied CC. - - -- My guess is that only allowing access to stream files is the quickest - way to get around the most issues. Therefore all files need to to be - checked to be sure they will be stream/lf before processing them. This is - the easiest way out, I know. The reason for this is that code that needs to - report the filesize will become a pain in the ass otherwise. - - Exit status.... Well we needed something done here, - - VMS has a structured exist status: - | 3 | 2 | 1 | 0| - |1098|765432109876|5432109876543|210| - +----+------------+-------------+---+ - |Ctrl| Facility | Error code |sev| - +----+------------+-------------+---+ - - With the Ctrl-bits an application can tell if part or the whole message has - already been printed from the program, DCL doesn't need to print it again. - - Facility - basically the program ID. A code assigned to the program - the name can be fetched from external or internal message libraries - Error code - the err codes assigned by the application - Sev. - severity: Even = error, off = non error - - 0 = Warning - 1 = Success - 2 = Error - 3 = Information - 4 = Fatal - <5-7> reserved. - - This all presents itself with: - %<FACILITY>-<Sev>-<Errorname>, <Error message> - - See also the src/curlmsg.msg file, it has the source for the messages In - src/main.c a section is devoted to message status values, the globalvalues - create symbols with certain values, referenced from a compiled message - file. Have all exit function use a exit status derived from a translation - table with the compiled message codes. - - This was all compiled with: - - Compaq C V6.2-003 on OpenVMS Alpha V7.1-1H2 - - So far for porting notes as of: - - 13-jul-2001 - N. Baggus - -QNX -=== - - (This section was graciously brought to us by David Bentham) - - As QNX is targeted for resource constrained environments, the QNX headers - set conservative limits. This includes the FD_SETSIZE macro, set by default - to 32. Socket descriptors returned within the CURL library may exceed this, - resulting in memory faults/SIGSEGV crashes when passed into select(..) - calls using fd_set macros. - - A good all-round solution to this is to override the default when building - libcurl, by overriding CFLAGS during configure, example - - # configure CFLAGS='-DFD_SETSIZE=64 -g -O2' - -RISC OS -======= - - The library can be cross-compiled using gccsdk as follows: - - CC=riscos-gcc AR=riscos-ar RANLIB='riscos-ar -s' ./configure \ - --host=arm-riscos-aof --without-random --disable-shared - make - - where riscos-gcc and riscos-ar are links to the gccsdk tools. - You can then link your program with curl/lib/.libs/libcurl.a - -AmigaOS -======= - - (This section was graciously brought to us by Diego Casorran) - - To build curl/libcurl on AmigaOS just type 'make amiga' ... - - What you need is: (not tested with others versions) - - GeekGadgets / gcc 2.95.3 (http://www.geekgadgets.org/) - - AmiTCP SDK v4.3 (http://www.aminet.net/comm/tcp/AmiTCP-SDK-4.3.lha) - - Native Developer Kit (http://www.amiga.com/3.9/download/NDK3.9.lha) - - As no ixemul.library is required you will be able to build it for - WarpOS/PowerPC (not tested by me), as well a MorphOS version should be - possible with no problems. - - To enable SSL support, you need a OpenSSL native version (without ixemul), - you can find a precompiled package at http://amiga.sourceforge.net/OpenSSL/ - -NetWare -======= - - To compile curl.nlm / libcurl.nlm you need: - - - either any gcc / nlmconv, or CodeWarrior 7 PDK 4 or later. - - gnu make and awk running on the platform you compile on; - native Win32 versions can be downloaded from: - http://www.gknw.net/development/prgtools/ - - recent Novell LibC or Novell CLib SDK available from: - https://www.novell.com/developer/ndk/ - - optional recent Novell CLDAP SDK available from: - https://www.novell.com/developer/ndk/ldap_libraries_for_c.html - - optional zlib sources (static or dynamic linking with zlib.imp); - sources with NetWare Makefile can be obtained from: - http://www.gknw.net/mirror/zlib/ - - optional OpenSSL sources (version 0.9.8 or later build with BSD sockets); - you can find precompiled packages at: - http://www.gknw.net/development/ossl/netware/ - for CLIB-based builds OpenSSL 0.9.8h or later is required - earlier versions - don't support building with CLIB BSD sockets. - - optional SSH2 sources (version 0.17 or later); - - Set a search path to your compiler, linker and tools; on Linux make - sure that the var OSTYPE contains the string 'linux'; set the var - NDKBASE to point to the base of your Novell NDK; and then type - 'make netware' from the top source directory; other targets available - are 'netware-ssl', 'netware-ssl-zlib', 'netware-zlib' and 'netware-ares'; - if you need other combinations you can control the build with the - environment variables WITH_SSL, WITH_ZLIB, WITH_ARES, WITH_SSH2, and - ENABLE_IPV6; you can set LINK_STATIC=1 to link curl.nlm statically. - By default LDAP support is enabled, however currently you will need a patch - in order to use the CLDAP NDK with BSD sockets (Novell Bug 300237): - http://www.gknw.net/test/curl/cldap_ndk/ldap_ndk.diff - I found on some Linux systems (RH9) that OS detection didn't work although - a 'set | grep OSTYPE' shows the var present and set; I simply overwrote it - with 'OSTYPE=linux-rh9-gnu' and the detection in the Makefile worked... - Any help in testing appreciated! - Builds automatically created 8 times a day from current git are here: - http://www.gknw.net/mirror/curl/autobuilds/ - the status of these builds can be viewed at the autobuild table: - https://curl.haxx.se/dev/builds.html - -eCos -==== - - curl does not use the eCos build system, so you must first build eCos - separately, then link curl to the resulting eCos library. Here's a sample - configure line to do so on an x86 Linux box targeting x86: - - GCCLIB=`gcc -print-libgcc-file-name` && \ - CFLAGS="-D__ECOS=1 -nostdinc -I$ECOS_INSTALL/include \ - -I`dirname $GCCLIB`/include" \ - LDFLAGS="-nostdlib -Wl,--gc-sections -Wl,-static \ - -L$ECOS_INSTALL/lib -Ttarget.ld -ltarget" \ - ./configure --host=i386 --disable-shared \ - --without-ssl --without-zlib --disable-manual --disable-ldap - - In most cases, eCos users will be using libcurl from within a custom - embedded application. Using the standard 'curl' executable from - within eCos means facing the limitation of the standard eCos C - startup code which does not allow passing arguments in main(). To - run 'curl' from eCos and have it do something useful, you will need - to either modify the eCos startup code to pass in some arguments, or - modify the curl application itself to retrieve its arguments from - some location set by the bootloader or hard-code them. - - Something like the following patch could be used to hard-code some - arguments. The MTAB_ENTRY line mounts a RAM disk as the root filesystem - (without mounting some kind of filesystem, eCos errors out all file - operations which curl does not take to well). The next section synthesizes - some command-line arguments for curl to use, in this case to direct curl - to read further arguments from a file. It then creates that file on the - RAM disk and places within it a URL to download: a file: URL that - just happens to point to the configuration file itself.

Open the Command Prompt window and change directory ('cd') - to the libcurl 'lib' folder. - 2. Add CYGWIN 'bin' folder to the PATH environment variable. - For example, type 'set PATH=C:/embedded/cygwin/bin;%PATH%'. - 3. Adjust environment variables defined in 'Environment' section - of the Makefile.vxworks file to point to your software folders. - 4. Build the libcurl by typing 'make -f ./Makefile.vxworks' - - As a result the libcurl.a library should be created in the 'lib' folder. - To clean the build results type 'make -f ./Makefile.vxworks clean'. - -Android -======= - - Method using the static makefile: - - - see the build notes in the packages/Android/Android.mk file. - - Method using a configure cross-compile (tested with Android NDK r7c, r8): - - - prepare the toolchain of the Android NDK for standalone use; this can - be done by invoking the script: - ./build/tools/make-standalone-toolchain.sh - which creates a usual cross-compile toolchain. Lets assume that you put - this toolchain below /opt then invoke configure with something like: - export PATH=/opt/arm-linux-androideabi-4.4.3/bin:$PATH - ./configure --host=arm-linux-androideabi [more configure options] - make - - if you want to compile directly from our GIT repo you might run into - this issue with older automake stuff: - checking host system type... - Invalid configuration `arm-linux-androideabi': - system `androideabi' not recognized - configure: error: /bin/sh ./config.sub arm-linux-androideabi failed - this issue can be fixed with using more recent versions of config.sub - and config.guess which can be obtained here: - http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree - you need to replace your system-own versions which usually can be - found in your automake folder: - find /usr -name config.sub - - Wrapper for pkg-config: - - - In order to make proper use of pkg-config so that configure is able to - find all dependencies you should create a wrapper script for pkg-config; - file /opt/arm-linux-androideabi-4.4.3/bin/arm-linux-androideabi-pkg-config: - - #!/bin/sh - SYSROOT=$(dirname ${0%/*})/sysroot - export PKG_CONFIG_DIR= - export PKG_CONFIG_LIBDIR=${SYSROOT}/usr/local/lib/pkgconfig:${SYSROOT}/usr/share/pkgconfig - export PKG_CONFIG_SYSROOT_DIR=${SYSROOT} - exec pkg-config "$@" - - also create a copy or symlink with name arm-unknown-linux-androideabi-pkg-config. - -CROSS COMPILE -============= - - (This section was graciously brought to us by Jim Duey, with additions by - Dan Fandrich) - - Download and unpack the curl package. - - 'cd' to the new directory. (e.g. cd curl-7.12.3) - - Set environment variables to point to the cross-compile toolchain and call - configure with any options you need. Be sure and specify the '--host' and - '--build' parameters at configuration time. The following script is an - example of cross-compiling for the IBM 405GP PowerPC processor using the - toolchain from MonteVista for Hardhat Linux. - - (begin script) - - #! /bin/sh - - export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin - export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include" - export AR=ppc_405-ar - export AS=ppc_405-as - export LD=ppc_405-ld - export RANLIB=ppc_405-ranlib - export CC=ppc_405-gcc - export NM=ppc_405-nm - - ./configure --target=powerpc-hardhat-linux \ - --host=powerpc-hardhat-linux \ - --build=i586-pc-linux-gnu \ - --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local \ - --exec-prefix=/usr/local - - (end script) - - You may also need to provide a parameter like '--with-random=/dev/urandom' - to configure as it cannot detect the presence of a random number - generating device for a target system. The '--prefix' parameter - specifies where curl will be installed. If 'configure' completes - successfully, do 'make' and 'make install' as usual. - - In some cases, you may be able to simplify the above commands to as - little as: - - ./configure --host=ARCH-OS - -REDUCING SIZE -============= - - There are a number of configure options that can be used to reduce the - size of libcurl for embedded applications where binary size is an - important factor. First, be sure to set the CFLAGS variable when - configuring with any relevant compiler optimization flags to reduce the - size of the binary. For gcc, this would mean at minimum the -Os option, - and potentially the -march=X, -mdynamic-no-pic and -flto options as well, - e.g. - - ./configure CFLAGS='-Os' LDFLAGS='-Wl,-Bsymbolic'... - - Note that newer compilers often produce smaller code than older versions - due to improved optimization. - - Be sure to specify as many --disable- and --without- flags on the configure - command-line as you can to disable all the libcurl features that you - know your application is not going to need. Besides specifying the - --disable-PROTOCOL flags for all the types of URLs your application - will not use, here are some other flags that can reduce the size of the - library: - - --disable-ares (disables support for the C-ARES DNS library) - --disable-cookies (disables support for HTTP cookies) - --disable-crypto-auth (disables HTTP cryptographic authentication) - --disable-ipv6 (disables support for IPv6) - --disable-manual (disables support for the built-in documentation) - --disable-proxy (disables support for HTTP and SOCKS proxies) - --disable-unix-sockets (disables support for UNIX sockets) - --disable-verbose (eliminates debugging strings and error code strings) - --disable-versioned-symbols (disables support for versioned symbols) - --enable-hidden-symbols (eliminates unneeded symbols in the shared library) - --without-libidn (disables support for the libidn DNS library) - --without-librtmp (disables support for RTMP) - --without-ssl (disables support for SSL/TLS) - --without-zlib (disables support for on-the-fly decompression) - - The GNU compiler and linker have a number of options that can reduce the - size of the libcurl dynamic libraries on some platforms even further. - Specify them by providing appropriate CFLAGS and LDFLAGS variables on the - configure command-line, e.g. - - CFLAGS="-Os -ffunction-sections -fdata-sections \ - -fno-unwind-tables -fno-asynchronous-unwind-tables -flto" \ - LDFLAGS="-Wl,-s -Wl,-Bsymbolic -Wl,--gc-sections" - - Be sure also to strip debugging symbols from your binaries after - compiling using 'strip' (or the appropriate variant if cross-compiling). - If space is really tight, you may be able to remove some unneeded - sections of the shared library using the -R option to objcopy (e.g. the - .comment section). - - Using these techniques it is possible to create a basic HTTP-only shared - libcurl library for i386 Linux platforms that is only 109 KiB in size, and - an FTP-only library that is 109 KiB in size (as of libcurl version 7.45.0, - using gcc 4.9.2). - - You may find that statically linking libcurl to your application will - result in a lower total size than dynamically linking. - - Note that the curl test harness can detect the use of some, but not all, of - the --disable statements suggested above. Use will cause tests relying on - those features to fail. The test harness can be manually forced to skip - the relevant tests by specifying certain key words on the runtests.pl - command line. Following is a list of appropriate key words: - - --disable-cookies !cookies - --disable-manual !--manual - --disable-proxy !HTTP\ proxy !proxytunnel !SOCKS4 !SOCKS5 - -PORTS -===== - - This is a probably incomplete list of known hardware and operating systems - that curl has been compiled for.

I figured that a few easy steps would accomplish -this without major headaches. I had no idea that I would be facing an almost -insurmountable challenge. - -The main problem lies in two areas. First the bulk of support for libcurl -exists for a Unix/linux command line environments.

A definite improvement that I am unwilling to give up. However using -DevCpp presented its own set of issues. Inadvertently I also made some -careless errors such as compiling the 7.14 version of Makefile with an older -version of source code. Thanks to Dan Fandrich for picking this up. - -I did eventually with the help of Daniel, Phillipe and others manage to -implement successfully (the only mingw available version) -curl-7.13.0-win32-ssl-devel-mingw32 into the DevCpp environment. Only the -dynamic libcurl.dll libcurldll.a libraries worked. The static library which I -was interested in did not. Furthermore when I tried to implement one of the -examples included with the curl package (get info.c) it caused the executable -to crash. Tracing the bug I found it in the code and function res = -curl_easy_perform(curl);. - -At this point I had to make a choice as to whether invest my limited -time-energy resource to fixing the bug or to compile the new version -available. After searching the archives I found a very similar or the same bug -reported from version 7.12x on. Daniel did inform me that he thought that this -bug had been fixed with the latest version. So I proceeded to compile the -latest SSL version where I faced other challenges. - -In order to make this process unremarkable for others using the same -environment I decided to document the process so that others will find it -routine. It would be a shame if newbies could not implement this excellent -package for their use. - -I would like to thank the many others in this forum and in the DevCpp forum -for their help. Without your help I may either have given up or it would have -taken me many times longer to achieve success. - -The Cookbook Approach ---------------------- - -This discussion will be confined to a SSL static library compilation and -installation. Limited mention and comments will be inserted where appropriate -to help with non-SSL, dynamic libraries and executables. - - - Using Makefile from DevCpp to compile Libcurl libraries - -Preamble --------- - -Using the latest version release - curl-7.14.0.tar.gz. Curl source code is -platform independent. This simply means that the source code can be compiled -for any Operating System (Linux/Unix Windows etc. and variations of thereof). - -The first thing to note is that inside curl-7.14.0 you will find two folders -lib and src. Both contain Makefile.m32 (required for win mingw library or exe -compilation) files which are different. The main difference between these two -folders and the makefiles is that the src folder contents are used to compile -an executable file(curl.exe) while the lib folder contents are used to compile -a static (libcurl.a) and dynamic (libcurl.dll & libcurldll.a) file that can be -used to compile libcurl with your own source code so that one can use and -access all libcurl functions. - -Before we start please make sure that DevCpp is installed properly. In -particular make sure you have no spaces in the name of any of the directories -and subdirectories where DevCpp is installed. Failure to comply with the -install instructions may produce erratic behaviour in DevCpp. For further info -check the following sites - -http://aditsu.freeunixhost.com/dev-cpp-faq.html -https://sourceforge.net/p/dev-cpp/discussion/48211/thread/2a85ea46 - -As I have mentioned before I will confine this to the SSL Library compilations -but the process is very similar for compilation of the executable - curl.exe; -just substitute the src folder makefile in its stead. - -First use a text processor Notepad, or your own favourite text processor. To -engage your favourite text processor, select Makefile.m32 click once with your -mouse on file icon; icon turns blue, press the shift key and right-click on -mouse, menu appears select "Open with", select your favourite text processor. - -Next read the contents of Makefile.m32. It includes instructions on its use. - -Method I - DOS Command Line ---------------------------- - -Note - The only reason I have included this method is that Method II which is -the preferred method for compiling does not allow for the setting of option -switches (e.g. SSL = 1 or SSL =0). At least that's what they tell me at the -Dev-Cpp forum. - -1 - Make a copy of (D:\Dev-Cpp\bin) bin folder and name it "bin Original" -place it in the Dev-Cpp installed directory (D:\Dev-Cpp\ for this example) - -2 - Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip -version into the bin folder above (D:\Dev-Cpp\bin). The reason being is that -the make.exe file resides in this folder. Make.exe will use - Makefile.m32, -Makefile.inc, and the source code included in the lib folder to compile the -source code. There is a PATH issue with make.exe that remains unresolved at -least for me. Unless the entire source code to be compiled is placed entirely -within the directory of make.exe an error message will be generated - "file -xxxx.yyy not available". - -3- Go to Dev-Cpp\bin and double click on make .exe. You will see a DOS window -quickly pop up and close very quickly. Not to worry! Please do not skip this -step. - -4- Click on the start button\Programs\MS-DOS Prompt.Once the DOS Window is up -Type the disk drive letter (e.g. E: ) engage the enter button. The path should -automatically take you to the directory of the make.exe file. - -5- To compile the source code simply type at the DOS prompt make -f -Makefile.m32 as per instructions contained in the Makefile.m32 file (use any -text processor to read instructions). I don't believe that this makefile -allows for the option of non SSL. Ignore any warnings. - -6- Collect and make copies of libcurl.a, libcurl.dll, libcurldll.a and any *.o -compilations you might need in another directory outside of the bin directory -as you will need this files shortly to set up libcurl for use with -Dev-cpp. For most apps *.o is not required. Later on we will show what to do -with these files. - -7- You are finished but before closing we need to do cleanup - erase the bin -folder and rename the "bin Original" folder created in step 1 to bin. - -Note to compile a curl executable the process is probably similar but instead -of using the LIB folder contents use the SRC folder contents and Makefiles in -curl-7.14.0.tar.gz. File directories relative placements must be respected for -compiling to take place successfully. This may not be possible with the PATH -problem that make.exe experiences. If anyone has solved this PATH issue and -please make sure it actually works on Win 9x/2000/XP before letting me -know. Then please let me or Daniel in on the solution so that it can be -included with these instructions. Thanks. - -or - -Method II - Dev-Cpp GUI ------------------------ - -1- Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip -version into any folder outside of (Dev-Cpp\bin). - -2- Drop the File/New/click on Project. - -3- New Project Dialogue box appears. Double click on the Static Library. - -4- Create Project Dialogue box appears. Select the LIB folder location to -place and locate your Project File Name.

To set this definition you have the +following alternatives: + + - Modify lib/config-win32.h and src/config-win32.h + - Modify lib/Makefile.vc6 + - Modify the "Preprocessor Definitions" in the libcurl project + +Note: The pre-processor settings can be found using the Visual Studio IDE +under "Project -> Settings -> C/C++ -> General" in VC6 and "Project -> +Properties -> Configuration Properties -> C/C++ -> Preprocessor" in later +versions. + +Once that libcurl has been built with BSD-style lwIP TCP/IP stack support, in +order to use it with your program it is mandatory that your program includes +lwIP header file `<lwip/opt.h>` (or another lwIP header that includes this) +before including any libcurl header. Your program does not need the +`USE_LWIPSOCK` preprocessor definition which is for libcurl internals only. + +Compilation has been verified with [lwIP +1.4.0](http://download.savannah.gnu.org/releases/lwip/lwip-1.4.0.zip) and +[contrib-1.4.0](http://download.savannah.gnu.org/releases/lwip/contrib-1.4.0.zip). + +This BSD-style lwIP TCP/IP stack support must be considered experimental given +that it has been verified that lwIP 1.4.0 still needs some polish, and libcurl +might yet need some additional adjustment, caveat emptor. + +## Important static libcurl usage note + +When building an application that uses the static libcurl library on Windows, +you must add `-DCURL_STATICLIB` to your `CFLAGS`. Otherwise the linker will +look for dynamic import symbols. + +## Legacy Windows and SSL + +WinSSL (specifically SChannel from Windows SSPI), is the native SSL library in +Windows. However, WinSSL in Windows <= XP is unable to connect to servers that +no longer support the legacy handshakes and algorithms used by those +versions. If you will be using curl in one of those earlier versions of +Windows you should choose another SSL backend such as OpenSSL. + +# Apple iOS and Mac OS X + +On modern Apple operating systems, curl can be built to use Apple's SSL/TLS +implementation, Secure Transport, instead of OpenSSL. To build with Secure +Transport for SSL/TLS, use the configure option `--with-darwinssl`. (It is not +necessary to use the option `--without-ssl`.) This feature requires iOS 5.0 or +later, or OS X 10.5 ("Leopard") or later. + +When Secure Transport is in use, the curl options `--cacert` and `--capath` +and their libcurl equivalents, will be ignored, because Secure Transport uses +the certificates stored in the Keychain to evaluate whether or not to trust +the server. This, of course, includes the root certificates that ship with the +OS. The `--cert` and `--engine` options, and their libcurl equivalents, are +currently unimplemented in curl with Secure Transport. + +For OS X users: In OS X 10.8 ("Mountain Lion"), Apple made a major overhaul to +the Secure Transport API that, among other things, added support for the newer +TLS 1.1 and 1.2 protocols. To get curl to support TLS 1.1 and 1.2, you must +build curl on Mountain Lion or later, or by using the equivalent SDK. If you +set the `MACOSX_DEPLOYMENT_TARGET` environmental variable to an earlier +version of OS X prior to building curl, then curl will use the new Secure +Transport API on Mountain Lion and later, and fall back on the older API when +the same curl binary is executed on older cats. For example, running these +commands in curl's directory in the shell will build the code such that it +will run on cats as old as OS X 10.6 ("Snow Leopard") (using bash): + + export MACOSX_DEPLOYMENT_TARGET="10.6" + ./configure --with-darwinssl + make + +# Cross compile + +Download and unpack the curl package. + +'cd' to the new directory. (e.g. `cd curl-7.12.3`) + +Set environment variables to point to the cross-compile toolchain and call +configure with any options you need. Be sure and specify the `--host` and +`--build` parameters at configuration time. The following script is an +example of cross-compiling for the IBM 405GP PowerPC processor using the +toolchain from MonteVista for Hardhat Linux. + + #! /bin/sh + + export PATH=$PATH:/opt/hardhat/devkit/ppc/405/bin + export CPPFLAGS="-I/opt/hardhat/devkit/ppc/405/target/usr/include" + export AR=ppc_405-ar + export AS=ppc_405-as + export LD=ppc_405-ld + export RANLIB=ppc_405-ranlib + export CC=ppc_405-gcc + export NM=ppc_405-nm + + ./configure --target=powerpc-hardhat-linux + --host=powerpc-hardhat-linux + --build=i586-pc-linux-gnu + --prefix=/opt/hardhat/devkit/ppc/405/target/usr/local + --exec-prefix=/usr/local + +You may also need to provide a parameter like `--with-random=/dev/urandom` to +configure as it cannot detect the presence of a random number generating +device for a target system. The `--prefix` parameter specifies where curl +will be installed. If `configure` completes successfully, do `make` and `make +install` as usual. + +In some cases, you may be able to simplify the above commands to as little as: + + ./configure --host=ARCH-OS + +# REDUCING SIZE + +There are a number of configure options that can be used to reduce the size of +libcurl for embedded applications where binary size is an important factor. +First, be sure to set the CFLAGS variable when configuring with any relevant +compiler optimization flags to reduce the size of the binary. For gcc, this +would mean at minimum the -Os option, and potentially the `-march=X`, +`-mdynamic-no-pic` and `-flto` options as well, e.g. + + ./configure CFLAGS='-Os' LDFLAGS='-Wl,-Bsymbolic'... + +Note that newer compilers often produce smaller code than older versions +due to improved optimization. + +Be sure to specify as many `--disable-` and `--without-` flags on the +configure command-line as you can to disable all the libcurl features that you +know your application is not going to need. Besides specifying the +`--disable-PROTOCOL` flags for all the types of URLs your application will not +use, here are some other flags that can reduce the size of the library: + + - `--disable-ares` (disables support for the C-ARES DNS library) + - `--disable-cookies` (disables support for HTTP cookies) + - `--disable-crypto-auth` (disables HTTP cryptographic authentication) + - `--disable-ipv6` (disables support for IPv6) + - `--disable-manual` (disables support for the built-in documentation) + - `--disable-proxy` (disables support for HTTP and SOCKS proxies) + - `--disable-unix-sockets` (disables support for UNIX sockets) + - `--disable-verbose` (eliminates debugging strings and error code strings) + - `--disable-versioned-symbols` (disables support for versioned symbols) + - `--enable-hidden-symbols` (eliminates unneeded symbols in the shared library) + - `--without-libidn` (disables support for the libidn DNS library) + - `--without-librtmp` (disables support for RTMP) + - `--without-ssl` (disables support for SSL/TLS) + - `--without-zlib` (disables support for on-the-fly decompression) + +The GNU compiler and linker have a number of options that can reduce the +size of the libcurl dynamic libraries on some platforms even further. +Specify them by providing appropriate CFLAGS and LDFLAGS variables on the +configure command-line, e.g. + + CFLAGS="-Os -ffunction-sections -fdata-sections + -fno-unwind-tables -fno-asynchronous-unwind-tables -flto" + LDFLAGS="-Wl,-s -Wl,-Bsymbolic -Wl,--gc-sections" + +Be sure also to strip debugging symbols from your binaries after compiling +using 'strip' (or the appropriate variant if cross-compiling). If space is +really tight, you may be able to remove some unneeded sections of the shared +library using the -R option to objcopy (e.g. the .comment section). + +Using these techniques it is possible to create a basic HTTP-only shared +libcurl library for i386 Linux platforms that is only 109 KiB in size, and an +FTP-only library that is 109 KiB in size (as of libcurl version 7.45.0, using +gcc 4.9.2). + +You may find that statically linking libcurl to your application will result +in a lower total size than dynamically linking. + +Note that the curl test harness can detect the use of some, but not all, of +the `--disable` statements suggested above. Use will cause tests relying on +those features to fail. The test harness can be manually forced to skip the +relevant tests by specifying certain key words on the runtests.pl command +line. Following is a list of appropriate key words: + + - `--disable-cookies` !cookies + - `--disable-manual` !--manual + - `--disable-proxy` !HTTP\ proxy !proxytunnel !SOCKS4 !SOCKS5 + +# PORTS + +This is a probably incomplete list of known hardware and operating systems +that curl has been compiled for.
