Not this heisenbug again...
Comment 4 Marek Szuba archtester gentoo-dev 2020-09-03 15:26:30 UTC
As before: what do you get when you run 'readelf -d /usr/lib/llvm/10/lib64/* | grep SONAME'?

 0x000000000000000e (SONAME)             Library soname: []
 0x000000000000000e (SONAME)             Library soname: []

I guess that the issue comes from the fact that CMakeLists.txt is calling readelf directly and I don't have it with sys-devel/binutils-config and sys-devel/gcc-config -native-symlink

Progress at last! Will think about how to fix this properly.
Comment 7 Marek Szuba archtester gentoo-dev 2020-09-07 11:04:30 UTC
The direct 'readelf' call is still there on the master branch so upstream has been notified. Unfortunately I haven't figured out how to make CMake detect the toolchain prefix (it seems IGC doesn't use any of the modules which do it), and using the value of CHOST to pass it from the outside breaks multilib (for abi_x86_32 runs, CHOST gets rewritten to i686-pc-linux-gnu). Fortunately, as far as distribution packages are concerned there is an easy workaround - assume the package manager has got dependencies under control and bypass the opencl-clang version check in IGC altogether.

    dev-util/intel-graphics-compiler: bypass opencl-clang version check
    Ebuilds already make sure we have a new-enough version of
    dev-libs/opencl-clang present, besides we have never even had versions
    older than 5.0.0 in the tree. No opencl-clang version check in CMake -
    no need to call readelf - no more issues on USE=-native-symlinks
