Hi, @RarogCmex , could you try if following change can fix the build failure?
in xgl/CMakeLists.txt, add following lines right after project(XGL VERSION 1 LANGUAGES C CXX):

if(UNIX)
if("${CMAKE_CXX_COMPILER_ID}" STREQUAL "GNU")
set(CMAKE_AR /usr/bin/gcc-ar)
set(CMAKE_RANLIB /usr/bin/gcc-ranlib)
endif()
endif()

thanks

[RarogCmex]

Thank you so for fast answer, but it could not help:
build.log
Also, previous version 2020.1.2 builded successfully

Complete ebuild

The following snippet of build.log:
FAILED: llpc/amdllpc

[RarogCmex]

The situation is clarified. AMDVLK doesn't support full building with cmake, it seems that compiling with cmake broken. When I switch to more generic method of ebuild it become working.
So I'm not sure that is issue.

[JaxLinAMD]

@RarogCmex , what do you mean by "ebuild"? Did you use some special method to build driver so that driver build is successful?

[Johnnynator]

@RarogCmex Can you provide the full cmake command and env vars in use when compiling?

@RarogCmex , what do you mean by "ebuild"? Did you use some special method to build driver so that driver build is successful?

Ebuild is the Gentoo name for a build definition for a package.

[RarogCmex]

I can't do it in this moment, sorry me.

[JaxLinAMD]

I need to setup Gentoo enviroment to check what's happening

[RarogCmex]

@JaxLinAMD Ok, thanks, here is how to install Gentoo https://wiki.gentoo.org/wiki/Handbook:AMD64/Full
with addition that instead building kernel in step 3 you may get more experimental ready-to-use ones: sys-kernel/gentoo-kernel
Mail me denis7774@gmail.com if you're experiencing issues.
I'll send ebuilds to test with it within a day.

[RarogCmex]

@JaxLinAMD
Also instead of full installation you may just chroot.
Here is ebuild (rename: erase all after the amdvlk-2020.1.4.ebuild )
amdvlk-2020.1.4.ebuild.works.txt

amdvlk-2020.1.4.ebuild.not_works.txt

You may just put it to /var/db/repos/gentoo (but make sure that there is no overwrites) or just create new ebuild repository https://wiki.gentoo.org/wiki/Ebuild_repository

[JaxLinAMD]

@RarogCmex , I found that driver is build through cmake utils provided by ebuild, which will generate build error, have you tried to build driver directly using cmake( no ebuild, only use cmake and make):

cmake -H. ***
make

[RarogCmex]

@JaxLinAMD Yes, see amdvlk-2020.1.4.ebuild.works.txt

[JaxLinAMD]

@RarogCmex , could you try to build with cmake directly in console without the help of ebuild to see if there is any error?
cmake -H. -Bbuilds/Release64
make -j8
I can compile successfully with cmake, in fact, I am not quite familiar with ebuild.

[RarogCmex]

@JaxLinAMD Yes, It works without errors.
Maybe it's portage cmake build system error, I don't have heath at this time
P.S. So do I about ebuilds, but I tries :)
