The code that is failing to build for you should not be compiled on Linux because its inside a pre-processor block of "if HAVE(STAT_BIRTHTIME)". And CMake should detect that and don't define HAVE_STAT_BIRTHTIME to true. Can you check in the file CMakeCache.txt file inside your build the value of HAVE_STAT_BIRTHTIME? If it is defined to true (1), then we need to look at what caused cmake to define that to true. The check that defines this is in the file Source/cmake/OptionsCommon.cmake in the call WEBKIT_CHECK_HAVE_STRUCT(HAVE_STAT_BIRTHTIME "struct stat" st_birthtime sys/stat.h) that calls the macro defined in Source/cmake/WebKitFeatures.cmake which ends calling cmake function check_struct_has_member() which its available at least since cmake 3.0 https://cmake.org/cmake/help/v3.0/module/CheckStructHasMember.html Can you paste here the output of the following command: grep -C25 -r HAVE_STAT_BIRTHTIME ${build-directory}/CMake* ? it should show the value that cmake picked for this, as well as how it performed the check
CMakeCache.txt //Test HAVE_STAT_BIRTHTIME_value HAVE_STAT_BIRTHTIME_value:INTERNAL=1 CMakeOutput.log CMakeFiles/CMakeOutput.log:Performing C SOURCE FILE Test HAVE_STAT_BIRTHTIME_value succeeded with the following output: CMakeFiles/CMakeOutput.log-Change Dir: /var/tmp/portage/net-libs/webkit-gtk-2.26.4/work/webkit-gtk-2.26.4_build/CMakeFiles/CMakeTmp CMakeFiles/CMakeOutput.log- CMakeFiles/CMakeOutput.log-Run Build Command(s):/usr/bin/ninja cmTC_3e055 CMakeFiles/CMakeOutput.log-[1/2] Building C object CMakeFiles/cmTC_3e055.dir/src.c.o CMakeFiles/CMakeOutput.log-[2/2] Linking C executable cmTC_3e055 CMakeFiles/CMakeOutput.log- CMakeFiles/CMakeOutput.log-Source file was: CMakeFiles/CMakeOutput.log- CMakeFiles/CMakeOutput.log-#include <sys/stat.h> CMakeFiles/CMakeOutput.log- CMakeFiles/CMakeOutput.log-int main() CMakeFiles/CMakeOutput.log-{ CMakeFiles/CMakeOutput.log- (void)sizeof(((struct stat *)0)->st_birthtime); CMakeFiles/CMakeOutput.log- return 0; CMakeFiles/CMakeOutput.log-}
That's very weird as I have no st_birthtime in my stat.h or any include file. I tried compiling the test with g++ manually, and it fails as it should.
I suspect something from the side of gentoo portage intervenes. Either distcc or ccache. Will try purging the cache and compiling locally.
Confirming, DistCC is playing tricks. It compiles without it
