What is needed to build?

[Moelf]

Initially I was prompted no HSA lib, so I installed https://aur.archlinux.org/packages/hsa-rocr/, then

(@v1.4) pkg> build AMDGPU
   Building AMDGPU → `~/.julia/packages/AMDGPU/6zgIY/deps/build.log`
┌ Error: Error building `AMDGPU`:
│ [ Info: libhsa-runtime64.so: true
│ ERROR: LoadError: LoadError: could not load library "/opt/rocm/hsa/lib/libhsa-runtime64.so"

Appears to be related to JuliaGL/GLFW.jl#198

Can you try removing Julia's libstdc++.so and see if that fixes it?

[Moelf]

umm, that seems to be a step in the right direction but then:

(@v1.4) pkg> build AMDGPU
   Building AMDGPU → `~/.julia/packages/AMDGPU/6zgIY/deps/build.log`
┌ Error: Error building `AMDGPU`:
│ paths = ["/opt/rocm/hsa/lib"]
│ Couldn't find ld.lld.
└ @ Pkg.Operations /buildworker/worker/package_linux64/build/usr/share/julia/stdlib/v1.4/Pkg/src/Operations.jl:892

That's because you need to have ld.lld installed on your system. It's not built by Julia, so it currently needs to be installed by the user. #27 is the issue to watch for that. If you can install it manually for now, that should get you further and probably get the package loading.

ok, install lld make it build at least, with:

│ Could not find library 'rocblas'.
│ Could not find library 'rocsparse'.
│ Could not find library 'rocalution'.
│ Could not find library 'rocfft'.
│ Could not find library 'rocrand'.
│ Could not find library 'MIOpen'.
│
│ ROCArrays.jl has been built successfully, but there were warnings.
│ Some functionality may be unavailable.

I guess more packages to manually install ;).
