Description Benjamin Block 2025-05-14 10:22:24 UTC

When installing dev-util/spirv-llvm-translator in PREFIX the resulting executable can't resolve symbols/libraries properly. The emerge works fine, but the result is unsuable

~ $ command -v llvm-spirv
/home/share/gentoo/usr/lib/llvm/19/bin/llvm-spirv
~ $ llvm-spirv
llvm-spirv: error while loading shared libraries: libLLVMSPIRVLib.so.19.1: cannot open shared object file: No such file or directory
~ $ readelf -a "$(command -v llvm-spirv)"

I'm guessing the RPATH/RUNPATH is missing the the executable, so it doesn't look at the right place for `libLLVMSPIRVLib.so.19.1`.

I attach build output.

Reproducible: Always
