edk2-linux-toolchain's Issues

Compilation fails with `error: ignoring return value of ‘write’ declared with attribute ‘warn_unused_result’ [-Werror=unused-result]`

When I compile this software, compilation fails with
main.c:432:17: error: ignoring return value of ‘write’ declared with attribute ‘warn_unused_result’ [-Werror=unused-result]:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

I build according to your PKGBUILD, gcc version is 13.1.1.

The error also appears if I add

    CFLAGS+=' -Wno-error=unused-result'
    CXXFLAGS+=' -Wno-error=unused-result'
    export CFLAGS
    export CXXFLAGS

to build() in your PKGBUILD.

Regards!
