2013-08-05configure: warn on bad env variable use, don't errorDaniel Stenberg
Use XC_CHECK_BUILD_FLAGS instead XC_CHECK_USER_FLAGS.
2013-08-05Revert "configure: don't error out on variable confusions, just warn"Daniel Stenberg
This reverts commit 6b27703b5f525eccdc0a8409f51de8595c75132a.
2013-08-04configure: don't error out on variable confusions, just warnDaniel Stenberg
2013-08-03configure: rephrase the notice in _XC_CHECK_VAR_*Daniel Stenberg
Instead of claiming it is an error, we call it a "note" to reduce the severity level. But the following text now says the [variable] "*should* only be used to specify"... instead of previously having said "may".

2013-02-23strcasestr: remove check for this unused functionDaniel Stenberg
2013-02-14strlcat: remove functionDaniel Stenberg
This function was only used twice, both in places where performance isn't crucial (socks + if2ip). Removing the use of this function removes the need to have our private version for systems without it == reduced amount of code. Also, in the SOCKS case it is clearly better to fail gracefully rather than to truncate the results. This work was triggered by a bug report on the strcal prototype in strequal.h. strlcat was added in commit db70cd28 in February 2001!

2013-01-25zz40-xc-ovr.m4: reinstate strict AC_REQUIRE macro dependenciesYang Tse
2013-01-25zz40-xc-ovr.m4: avoid double single-quote usageYang Tse
2013-01-25zz40-xc-ovr.m4: parentheses balancing of 'case' statementsYang Tse
m4 quadrigraph shell comment technique allows proper autoconf parentheses balancing in shell 'case' statements. The presence of unbalanced parentheses may otherwise trigger expansion bugs.

2013-01-23zz60-xc-ovr.m4: tighten XC_OVR_ZZ60 macro placement requirementsYang Tse
2013-01-23configure: use XC_CONFIGURE_PREAMBLE early checksYang Tse
Some basic checks we make were placed early enough in generated configure script when using autoconf 2.5X versions. Newer autoconf versions expand these checks much further into the configure script, rendering them useless. Using XC_CONFIGURE_PREAMBLE fixes placement of early intended checks across all our autoconf supported versions.
2013-01-23zz40-xc-ovr.m4: provide XC_CONFIGURE_PREAMBLE macroYang Tse
2013-01-21xc-cc-check.m4: re-evaluate exporting and AC_SUBST'ing varsYang Tse
Notes: When running a configure script that has nested packages (for example libcurl's configure with --enable-ares and c-ares sources embedded in curl tree) and AC_CONFIG_SUBDIRS([nested-subdir]) machinery is used to automatically run the nested configure script from within the parent configure script, it happens that the nested _shell_ script will inherit shell variables exported from the parent _shell_ script. If for example parent configure script sets and exports LDFLAGS and LIBS variables with proper values in order to link either a parent library or program with a library which will be configured and built by a nested package; It will happen that when the nested configure script runs, the nested library does not exist yet and _any_ link-test done in the nested configure will fail, such as those that autoconf macros perform in order to detect existing compiler and its characteristics, the result is that the nested configure script will fail with errors such as: configure: error: C compiler cannot create executables For now, we no longer export variables previously exported here. On the other hand, AC_SUBST'ing them is appropriate and even with nested packages each package's config.status gets its own package values. So we reinstate AC_SUBST'ing previously AC_SUBST'ed variables.

2013-01-20configure: autotools compatibility fixes - step IYang Tse
Fix proper macro expansion order across autotools versions for C compiler and preprocessor program checks.
2013-01-14configure: fix automake 1.13 compatibilityYang Tse
Tested with: buildconf: autoconf version 2.69 buildconf: autom4te version 2.69 buildconf: autoheader version 2.69 buildconf: automake version 1.13.1 buildconf: aclocal version 1.13.1 buildconf: libtool version 2.4 buildconf: GNU m4 version 1.4.16
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2013-01-01curl-override.m4: provide AC_CONFIG_MACRO_DIR definition conditionallyYang Tse
Provide a 'traceable' AC_CONFIG_MACRO_DIR definition only when using an autoconf version that does not provide it, instead of what we were doing up to now of providing and overriding AC_CONFIG_MACRO_DIR for all autoconf versions.
2012-12-28build: make use of 76 lib/*.h renamed filesYang Tse
76 private header files renamed to use our standard naming scheme. This change affects 322 files in libcurl's source tree.

2012-11-16autoconf: don't force-disable compiler debug optionDaniel Stenberg
When nothing is told to configure, we should not enforce switching off debug options with -g0 (or similar). We instead don't use -g at all in that situaion and therefore allow the user's CFLAGS settings possibly dictate what to do.
2012-08-16configure: remove the --enable/disable-nonblocking optionsDaniel Stenberg
Removing this option as it currently only functions to lure people into wrongly using it and falsely believing that libcurl will work fine without using nonblocking sockets internally - which leads to hard to track or understand errors.
2012-06-29curl-compilers.m4: remove -Wstrict-aliasing=3 from clangYang Tse
Currently it is unknown if there is any version of clang that actually supports -Wstrict-aliasing. What is known is that there are several that don't support it.
2012-06-26curl-compilers.m4: -Wstrict-aliasing=3 for warning enabled gcc and clang buildsYang Tse
2012-04-17build adjustments: commit 9e24b9c7 follow-upYang Tse
2012-04-16curl-compilers.m4: -Wno-pedantic-ms-format for Windows gcc 4.5 buildsYang Tse
When building a Windows target with gcc 4.5 or newer and strict compiler warnings enabled use -Wno-pedantic-ms-format in addition to other flags.
2012-04-14headers: surround GCC attribute names with double underscoresJonathan Nieder
This protects from attribute names being defined by third party's code. Improvement: http://curl.haxx.se/mail/lib-2012-04/0127.html
2012-04-11build adjustments: CURL_HIDDEN_SYMBOLS no longer defined in config filesYang Tse
configure script now provides conditional definitions for Makefile.am that result in CURL_HIDDEN_SYMBOLS being defined by resulting makefiles when appropriate. Additionally, configure script option for symbol hiding control is now named --enable-symbol-hiding --disable-symbol-hiding. While still valid, old option name --enable-hidden-symbols --disable-hidden-symbols will be deprecated in some future release.
2012-03-28curl-functions.m4: update detection logic of getaddrinfo() thread-safenessYang Tse
Take in account that h_errno might be a modifiable lvalue not defined as a C preprocessor macro
2012-03-21curl-functions.m4: update detection logic of getaddrinfo() thread-safenessYang Tse
Take in account that POSIX standard Issue 7 drops h_errno support. Now, we also consider getaddrinfo() to be thread-safe when (_POSIX_C_SOURCE >= 200809L) or (_XOPEN_SOURCE >= 700) independently of whether h_errno exists or not.
