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

2017-03-02configure: fix for --enable-pthreadsJay Satiro
Better handle options conflicts that can occur if --enable-pthreads. Bug: https://github.com/curl/curl/pull/1295 Reported-by: Marc-Antoine Perennou
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.
2016-10-18configure/CURL_CHECK_FUNC_POLL: disable poll completely on macDaniel Stenberg
... so that the same libcurl build easier can run on any version. Follow-up to issue #1057
2016-10-11configure: detect the broken poll() in macOS 10.12Daniel Stenberg
Fixes #1057
2016-06-21curl-compilers.m4: improve detection of GCC's -fvisibility= flagKamil Dudka
Some builds of GCC produce output on both stdout and stderr when --help --verbose is used. The 2>&1 redirection caused them to be arbitrarily interleaved with each other because of stream buffering. Consequently, grep failed to match the fvisibility= string in the mixed output, even though the string was present in GCC's standard output. This led to silently disabling symbol hiding in some builds of curl.
2016-04-21configure: ac_cv_ -> curl_cv_ for write-only varsIrfan Adilovic
These configure vars are modified in a curl-specific way but never evaluated or loaded from cache, even though they are designated as _cv_. We could either implement proper AC_CACHE_CHECKs for them, or remove them completely. Fixes #603 as ac_cv_func_gethostbyname is no longer clobbered, and AC_CHECK_FUNC(gethostbyname...) will no longer spuriously succeed after the first configure run with caching. `ac_cv_func_strcasecmp` is curious, see #770. `eval "ac_cv_func_$func=yes"` can still cause problems as it works in tandem with AC_CHECK_FUNCS and then potentially modifies its result. It would be best to rewrite this test to use a new CURL_CHECK_FUNCS macro, which works the same as AC_CHECK_FUNCS but relies on caching the values of curl_cv_func_* variables, without modifiying ac_cv_func_*.
2016-04-21configure: ac_cv_ -> curl_cv_ for r/w varsIrfan Adilovic
These configure vars are modified in a curl-specific way and modified by the configure process, but are never loaded from cache, even though they are designated as _cv_. We should implement proper AC_CACHE_CHECKs for them eventually.
2016-04-21configure: ac_cv_ -> curl_cv_ for all cached varsIrfan Adilovic
This was automated by: sed -b -i -f <(ack -A1 AC_CACHE_CHECK | \ ack -o 'ac_cv_.*?\b' | \ sort -u | xargs -n1 bash -c \ 'echo "s/$0/curl_cv_${0#ac_cv_}/g"') \ $(git ls-files) This only changed the prefix for 16 variables actually checked with AC_CACHE_CHECK.

2015-12-20configure: detect IPv6 support on WindowsJohannes Schindelin
This patch was "nicked" from the MINGW-packages project by Daniel. https://github.com/Alexpux/MINGW-packages/commit/9253d0bf58a1486e91f7efb5316e7fdb48fa4007 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2015-12-20configure: allow static builds on mingwDaniel Stenberg
This patch is adopted from the MINGW-packages project. It makes it possible to build curl both shared and static again. URL: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-curl
2015-09-26curl-confopts.m4: Add missing ')'Tatsuhiro Tsujikawa
... for CURL_CHECK_OPTION_RT Closes #456
2015-07-24configure: add --disable-rt optionMichał Fita
This option disables any attempts in configure to create dependency on stuff requiring linking to librt.so and libpthread.so, in this case this means clock_gettime(CLOCK_MONOTONIC, &mt). We were in need to build curl which doesn't link libpthread.so to avoid the following bug: https://sourceware.org/bugzilla/show_bug.cgi?id=16628.

2014-05-06Enable poll on darwin13Daniel Johnson
Poll has long been broken on Mac OS X. Starting with 10.9 (darwin13) it now works correctly so this patch enables it there.
2013-09-27configure: use icc options without spaceDaniel Stenberg
The latest version(s) of the icc compiler no longer accept the extra space in the -we (warning enable), -wd (warning disable), etc. Reported-by: Elmira A Semenova Bug: http://curl.haxx.se/mail/lib-2013-09/0182.html
2013-09-07configure: improve CURL_CHECK_COMPILER_PROTOTYPE_MISMATCHDaniel Stenberg
The compiler test used a variable before it was assigned when it tried to see how it acts on a mismatching prototype, which could cause a false positive.
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!
