2020-03-11configure: convert -I to -isystem as a last stepDaniel Stenberg
As all the -I uses in CFLAGS at that point are for system headers and third party libraries this helps us remove/ignore warnings on those! Closes #5060
2020-03-11configure: document 'compiler_num' for gccDaniel Stenberg
The CURL_CHECK_COMPILER_GNU_C function sets the number to MAJOR*100 + MINOR and ignores the patch version, and since gcc version 7 it only sets it to MAJOR*100. Reported-by: Stepan Efremov Ref: #5067 Closes #5069
2020-02-02cleanup: fix typos and wording in docs and commentsPedro Monreal
Closes #4869 Reviewed-by: Emil Engler and Daniel Gustafsson
2019-10-02ESNI: initial build/setupNiall
Closes #4011
2019-07-09configure: fix --disable-code-coverageJan Chren
This fixes the case when --disable-code-coverage supplied to ./configure would result in coverage="yes" being set. Closes #4099 Reviewed-by: Daniel Gustafsson <daniel@yesql.se>
2019-05-22configure/cmake: check for if_nametoindex()Daniel Stenberg
- adds the check to cmake - fixes the configure check to work for cross-compiled windows builds Closes #3917
2019-05-21configure: detect getsockname and getpeername on windows tooDaniel Stenberg
Made detection macros for these two functions in the same style as other functions possibly in winsock in the hope this will work better to detect these functions when cross-compiling for Windows. Follow-up to e91e4816123 Fixes #3913 Closes #3915
2019-03-15configure: add --with-amisslChris Young
AmiSSL is an Amiga native library which provides a wrapper over OpenSSL. It also requires all programs using it to use bsdsocket.library directly, rather than accessing socket functions through clib, which libcurl was not necessarily doing previously. Configure will now check for the headers and ensure they are included if found. Closes #3677
2019-02-22configure: remove the unused fdopen macroDaniel Stenberg
and the two remaining #ifdefs for it Closes #3600
2019-01-26configure: rewrite --enable-code-coverageDaniel Stenberg
The previously used ax_code_coverage.m4 is not license compatible and must not be used. Reported-by: William A. Rowe Jr Fixes #3497 Closes #3499
2019-01-16curl-compilers.m4: check for __ibmxl__ to detect xlclangDaniel Stenberg
Follow-up to 2fa0d57e2e3. The __xlc__ symbol is only defined there if a particular flag is used for legacy macros. Fixes #3474 Closes #3479
2019-01-15curl-compilers.m4: detect xlclangDaniel Stenberg
Since it isn't totally clang compatible, we detect this IBM clang front-end and if detected, avoids some clang specific magic. Reported-by: Kees Dekker Fixes #3474 Closes #3476

- replace tabs with spaces where possible - remove line ending spaces - remove double/triple newlines at EOF - fix a non-UTF-8 character - cleanup a few indentations/line continuations in manual examples Closes https://github.com/curl/curl/pull/3037
2018-08-21Enable more GCC warningsMarcel Raad
This enables the following additional warnings: -Wold-style-definition -Warray-bounds=2 instead of the default 1 -Wformat=2, but only for GCC 4.8+ as Wno-format-nonliteral is not respected for older versions -Wunused-const-variable, which enables level 2 instead of the default 1 -Warray-bounds also in debug mode through -ftree-vrp -Wnull-dereference also in debug mode through -fdelete-null-pointer-checks Closes https://github.com/curl/curl/pull/2747
2018-08-21curl-compilers: enable -Wimplicit-fallthrough=4 for GCCMarcel Raad
This enables level 4 instead of the default level 3, which of the currently used comments only allows /* FALLTHROUGH */ to silence the warning. Closes https://github.com/curl/curl/pull/2747
2018-08-21curl-compilers: enable -Wbad-function-cast on GCCMarcel Raad
This warning used to be enabled only for clang as it's a bit stricter on GCC. Silence the remaining occurrences and enable it on GCC too. Closes https://github.com/curl/curl/pull/2747
2018-06-15curl-confopts.m4: fix typo from ed224f23d5bebDaniel Stenberg
Fixes my local configure to detect a custom installed c-ares without pkgconfig.
2018-06-14configure: use pkg-config for c-ares detectionDaniel Stenberg
First check if there's c-ares information given as pkg-config info and use that as first preference. Reported-by: pszemus on github Fixes #2203 Closes #2658
2018-05-22configure: add missing m4/ax_compile_check_sizeof.m4Daniel Stenberg

2018-05-21configure: replace AC_TRY_RUN with CURL_RUN_IFELSEDaniel Stenberg
... and export LD_LIBRARY_PATH properly. This is a follow-up from 2d4c215. Fixes #2586 Reported-by: Bernhard Walle
2018-05-04configure: put CURLDEBUG and DEBUGBUILD in lib/curl_config.hFrank Gevaerts
They are removed from the compiler flags. This ensures that make dependency tracking will force a rebuild whenever configure --enable-debug or --enable-curldebug changes. Closes #2548
2018-04-16configure: keep LD_LIBRARY_PATH changes localDaniel Stenberg
... only set it when we actually have to run tests to reduce its impact on for example build commands etc. Fixes #2490 Closes #2492 Reported-by: Dmitry Mikhirev

2018-03-12curl-openssl.m4: fix spelling [ci skip]Viktor Szakats
2018-02-24curl-openssl.m4: Fix version check for OpenSSL 1.1.1Jay Satiro
- Add OpenSSL 1.1.1 to the header/library version lists. - Detect OpenSSL 1.1.1 library using its function ERR_clear_last_mark, which was added in that version. Prior to this change an erroneous header/library mismatch was caused by lack of OpenSSL 1.1.1 detection. I tested using openssl-1.1.1-pre1.
2018-01-30configure: set PATH_SEPARATOR to colon for PATH w/o separatorDaniel Stenberg
The logic tries to figure out what the path separator in the $PATH variable is, but if there's only one directory in the $PATH it fails. This change make configure *guess* on colon instead of erroring out, simply because that is probably the more common character. PATH_SEPARATOR can always be set by the user to override the guessing. (tricky bug to reproduce, as in my case for example the configure script requires binaries in more than one directory so passing in a PATH with a single dir fails.) Reported-by: Earnestly on github Fixes #2202 Closes #2265

2017-08-08ax_code_coverage.m4: update to latest versionMarcel Raad
This updates the script to aad5ad5fedb306b39f901a899b7bd305b66c418d from August 01, 2017. Notably, this removes the lconv version whitelist. Closes https://github.com/curl/curl/pull/1716
2017-07-10curl-compilers.m4: disable warning spam with Cygwin's clangMarcel Raad
When building with Cygwin or MinGW, libtool uses a wrapper executable instead of a wrapper script [1], which is written in C and throws missing-variable-declarations warnings. Don't enable these warnings on Cygwin and MinGW in order to avoid warnings for every executable built, which spams the test suite output when using Cygwin's clang. [1] https://www.gnu.org/software/libtool/manual/html_node/Wrapper-executables.html Closes https://github.com/curl/curl/pull/1665
2017-06-24curl-compilers.m4: fix unknown-warning-option on Apple clangMarcel Raad
Since 5598b0bd63f690c151074494ce47ef872f004ab4, clang -v is used to detect the clang version. The version number was expected to come after the word "version". For Apple clang, this doesn't work as it has its own versioning scheme. The version number is now first searched after the string "based on LLVM". This works for Apple clang before version 7, and also for e.g. Ubuntu's clang up to version 3.7. If it's not found and the version string contains "Apple LLVM version", clang version 3.7 is assumed, which is the version that comes with Xcode 7. Otherwise, the version number is still expected after the word "version", which works for very old Apple clang versions. Ref: https://trac.macports.org/wiki/XcodeVersionInfo Fixes https://github.com/curl/curl/issues/1606 Closes https://github.com/curl/curl/pull/1607
2017-06-16curl-compilers.m4: enable comma clang warningMarcel Raad
It usually warns when using commas instead of semicolons or other operators by accident. Closes https://github.com/curl/curl/pull/1578
2017-06-16curl-compilers.m4: enable missing-variable-declarations clang warningMarcel Raad
It usually warns when forgetting to declare TU-local variables static. Closes https://github.com/curl/curl/pull/1578
2017-06-16curl-compilers.m4: enable double-promotion warningMarcel Raad
Enable -Wdouble-promotion for both GCC and clang. It warns on implicit promotion from float to double. Closes https://github.com/curl/curl/pull/1578
2017-06-16curl-compilers.m4: enable vla warning for clangMarcel Raad
Previously, that warning was only implicitly active in C90 mode. Enable it unconditionally as already done for GCC. Closes https://github.com/curl/curl/pull/1578
2017-06-02build: provide easy code coverage measuringDaniel Stenberg
Closes #1528
2017-06-01curl-compilers.m4: escape square brackets in regexMarcel Raad
Otherwise, they are removed in the final configure file. Also changed sed to "$SED" like in most other calls in this file.
2017-06-01curl-compilers.m4: fix compiler_num for clangMarcel Raad
"clang -dumpversion" always returns "4.2.1", the GCC version that clang was initially compatible to. Use "clang -v" instead, which returns the actual clang version. Fixes https://github.com/curl/curl/issues/1522 Closes https://github.com/curl/curl/pull/1523
2017-05-31curl-compilers.m4: enable -Wshift-sign-overflow for clangMarcel Raad
clang 2.9+ supports -Wshift-sign-overflow, which warns about undefined behavior on signed left shifts when shifting by too many places. Ref: https://github.com/curl/curl/issues/1516 Closes https://github.com/curl/curl/pull/1517
2017-04-25configure: stop prepending to LDFLAGS, CPPFLAGSJay Satiro
- Change prepends to appends because user's LDFLAGS and CPPFLAGS should always come first so they're searched before ours. Bug: https://github.com/curl/curl/issues/1420 Reported-by: Helmut K. C. Tessarek
2017-04-24curl-compilers.m4: accept -Og and -Ofast GCC flagsMarcel Raad
-Og, introduced in GCC 4.8, optimizes for debugging experience. -Ofast, introduced in GCC 4.7, builds on -O3 and enables further optimizations breaking strict standards compliance. When specified in CFLAGS, these were always overridden by -O0 or -O2. Fix this by adding them to flags_opt_all. Ref: https://gcc.gnu.org/onlinedocs/gcc-4.8.0/gcc/Optimize-Options.html Ref: https://github.com/curl/curl/pull/1404#issuecomment-296401570 Closes https://github.com/curl/curl/pull/1440
2017-04-15curl-compilers.m4: turn implicit function declarations into errorsMarcel Raad
This adds -Werror-implicit-function-declaration for GCC 2.95+ so that these errors are visible at the point where they occur instead of only at link time. Implicit function declarations are illegal in C99 and C++ anyway, and the same warning has been turned into an error for ICC in commit 3072c5b8a127057aa922b7c51051bbb4a630b091. Ref: https://gcc.gnu.org/onlinedocs/gcc-2.95.2/gcc_2.html#SEC8 Ref: https://curl.haxx.se/mail/lib-2017-04/0001.html Closes https://github.com/curl/curl/pull/1419

2016-11-07s/cURL/curlDaniel Stenberg
We're mostly saying just "curl" in lower case these days so here's a big cleanup to adapt to this reality. A few instances are left as the project could still formally be considered called cURL.
