* configure: set -Wextra-semi-stmt for clang with --enable-debugDaniel Stenberg2020-12-291-0/+1
| | | | | | | To have it properly complain on empty statements with no effect. Ref: #6376 Closes #6378
* Revert "libcurl.pc: make it relocatable"Daniel Stenberg2020-11-093-344/+0
| | | | | | | | | | This reverts commit 3862c37b6373a55ca704171d45ba5ee91dec2c9f. That fix should either be done differently or with an option. Reported-by: asavah on github Fixes #6157 Closes #6183
* curl.se: new homeDaniel Stenberg2020-11-046-6/+6
| | | | Closes #6172
* libcurl.pc: make it relocatableCristian Morales Vega2020-10-153-0/+344
| | | | | | | | It supposes when people specify the libdir/includedir they do it to change where under prefix/exec_prefix it should be, not to make it independent of prefix/exec_prefix. Closes #6061
* ECH: renamed from ESNI in docs and configureDaniel Stenberg2020-09-291-21/+21
| | | | | | Encrypted Client Hello (ECH) is the current name. Closes #6022
* lib: fix -Wassign-enum warningsDaniel Stenberg2020-09-081-0/+4
| | | | | | | | | | configure --enable-debug now enables -Wassign-enum with clang, identifying several enum "abuses" also fixed. Reported-by: Gisle Vanem Bug: https://github.com/curl/curl/commit/879007f8118771f4896334731aaca5850a154675#commitcomment-42087553 Closes #5929
* configure: let --enable-debug set -Wenum-conversion with gcc >= 10Daniel Stenberg2020-09-071-0/+4
| | | | | | | | Unfortunately, this option is not detecting the same issues as clang's -Wassign-enum flag, but should still be useful to detect future mistakes. Closes #5930
* configure: allow disabling warningsMarcel Raad2020-07-171-48/+74
| | | | | | | | | | When using `--enable-warnings`, it was not possible to disable warnings via CFLAGS that got explicitly enabled. Now warnings are not enabled anymore if they are explicitly disabled (or enabled) in CFLAGS. This works for at least GCC, clang, and TCC as they have corresponding `-Wno-` options for every warning. Closes https://github.com/curl/curl/pull/5689
* configure: remove use of -vec-report0 from CFLAGS with iccDaniel Stenberg2020-04-061-5/+0
| | | | | | | ... as it apparently isn't (always) supported. Reported-by: Alain Miniussi Fixes #5096 Closes #5191
* copyright: fix out-of-date copyright ranges and missing headersDaniel Stenberg2020-03-2410-9/+30
| | | | | | | | | Reported by the new script 'scripts/copyright.pl'. The script has a regex whitelist for the files that don't need copyright headers. Removed three (mostly usesless) README files from docs/ Closes #5141
* curl-functions.m4: remove inappropriate AC_REQUIRERoss Burton2020-03-211-2/+0
| | | | | | | | | | | | | AC_REQUIRE means "if this macro hasn't been executed already, execute it". So in a wrapper around AC_RUN_IFELSE, AC_REQUIRE(AC_RUN_IFELSE) isn't correct at that will execute AC_RUN_IFELSE without any arguments. With autoconf 2.69 this is basically a no-op, but with autoconf 2.70, AC_RUN_IFELSE without a default value when cross-compiling is fatal. The result is that curl with autoconf 2.70 cannot cross-compile. Fixes https://github.com/curl/curl/issues/5126 Closes https://github.com/curl/curl/pull/5130
* configure: convert -I to -isystem as a last stepDaniel Stenberg2020-03-111-5/+4
| | | | | | | 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
* configure: document 'compiler_num' for gccDaniel Stenberg2020-03-111-3/+12
| | | | | | | | | | 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
* cleanup: fix typos and wording in docs and commentsPedro Monreal2020-02-022-5/+5

* ESNI: initial build/setupNiall2019-10-021-1/+37
| | | | Closes #4011
* configure: fix --disable-code-coverageJan Chren2019-07-091-2/+1
| | | | | | | | 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>
* configure/cmake: check for if_nametoindex()Daniel Stenberg2019-05-221-0/+113
| | | | | | | | - adds the check to cmake - fixes the configure check to work for cross-compiled windows builds Closes #3917
* configure: detect getsockname and getpeername on windows tooDaniel Stenberg2019-05-211-0/+195
| | | | | | | | | | | 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
* configure: add --with-amisslChris Young2019-03-151-0/+50
| | | | | | | | | | 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
* configure: remove the unused fdopen macroDaniel Stenberg2019-02-221-86/+0
| | | | | | and the two remaining #ifdefs for it Closes #3600
* configure: rewrite --enable-code-coverageDaniel Stenberg2019-01-262-265/+41
| | | | | | | | | 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
* curl-compilers.m4: check for __ibmxl__ to detect xlclangDaniel Stenberg2019-01-161-2/+2
| | | | | | | | Follow-up to 2fa0d57e2e3. The __xlc__ symbol is only defined there if a particular flag is used for legacy macros. Fixes #3474 Closes #3479
* curl-compilers.m4: detect xlclangDaniel Stenberg2019-01-151-2/+11
| | | | | | | | | 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

* Enable more GCC warningsMarcel Raad2018-08-211-1/+15
| | | | | | | | | | | | | | 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
* curl-compilers: enable -Wimplicit-fallthrough=4 for GCCMarcel Raad2018-08-211-0/+1
| | | | | | | | 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
* curl-compilers: enable -Wbad-function-cast on GCCMarcel Raad2018-08-211-0/+1
| | | | | | | 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

* configure: put CURLDEBUG and DEBUGBUILD in lib/curl_config.hFrank Gevaerts2018-05-042-10/+4
| | | | | | | | | 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

* curl-openssl.m4: Fix version check for OpenSSL 1.1.1Jay Satiro2018-02-241-1/+10
| | | | | | | | | | - 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.
* configure: set PATH_SEPARATOR to colon for PATH w/o separatorDaniel Stenberg2018-01-301-7/+5
| | | | | | | | | | | | | | | | | 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.)

* curl-compilers.m4: disable warning spam with Cygwin's clangMarcel Raad2017-07-101-1/+9
| | | | | | | | | | | | 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
* curl-compilers.m4: fix unknown-warning-option on Apple clangMarcel Raad2017-06-241-1/+10
| | | | | | | | | | | | | | | | | | 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.

* curl-compilers.m4: enable missing-variable-declarations clang warningMarcel Raad2017-06-161-0/+5
| | | | | | It usually warns when forgetting to declare TU-local variables static. Closes https://github.com/curl/curl/pull/1578
* curl-compilers.m4: enable double-promotion warningMarcel Raad2017-06-161-0/+10
| | | | | | | 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
* curl-compilers.m4: enable vla warning for clangMarcel Raad2017-06-161-0/+5
| | | | | | | 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
