elfutils:x64-osx failed in git fetch steps, this issue could repro on local machine, @Neumann-A , could you help have a look?

I tried the hash for the tag https://sourceware.org/git/?p=elfutils.git;a=tag;h=25d048684a82f9ba701c6939b7f28c3543bb7991, the git fetch works, it failed in config steps:

configure: WARNING: unrecognized options: --disable-shared, --enable-static
rm: conftest.dSYM: is a directory
configure: error: gcc with GNU99 support required

[Neumann-A]

configure: error: gcc with GNU99 support required

which version of gcc? Or what is the output of the config.log in the subdir <triplet>-dbg/?

[PhoebeHui]

Here is config log:
failure logs for x64-osx (1).zip

[Neumann-A]

@PhoebeHui: That are not the logs I need. I need the literally called config.log from <vcpkgroot>/buildtrees/<port>/<triplet>-<shortbuildtype>/config.log Unfortunally vcpkg_configure_make is not able to copy that file into buildtrees/<port> since vcpkg_execute_process does error before I can inject the code for copying that file one folder down.

[PhoebeHui]

Sorry, here is correct one:
config.log

[Neumann-A]

The error is:

configure:5173: result: no
configure:5176: error: gcc with GNU99 support required

which basically means that the compiler:

configure:3750: gcc --version >&5
Apple clang version 12.0.0 (clang-1200.0.32.2)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

does not support gnu extensions (-std=gnu99). As such I should probably put it on the CI skiplist on OSX? If a true gcc would be used on OSX it would probably compile.

[PhoebeHui]

Could you please add it to 'Supports" instead?

[Neumann-A]

@PhoebeHui: Supports seems wrong here. A custom toolchain switching to gcc on apple could compile this correctly.

[PhoebeHui]

@Neumann-A, thanks for the information!

I'm fine to put it on the CI skiplist on OSX, could add comments as well to ci.baseline.txt file?

[strega-nil]

Thanks @Neumann-A :)
