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.

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.
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

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 optionMichaƂ 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.

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.

2013-08-03configure: 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!
