rocm-comgr and rocm-opencl have been bumped for F40 to build w/ 'compat_build', but rocm-device-libs has not and the dependency chain and issued OpenCL compilation commands no longer match. As a result OpenCL kernels in darktable no longer compile at runtime OOTB on F40: fatal error: malformed or corrupted AST file: 'could not find file '/usr/lib64/llvm17/bin/../../../lib/clang/17/include/opencl-c-base.h' referenced by AST file '/tmp/comgr-00ca7b/include/opencl1.2-c.pch'' Error: Failed to compile source (from CL or HIP source to LLVM IR). I guess it's just a matter of forwarding the f40 branch to https://src.fedoraproject.org/rpms/rocm-device-libs/c/a9a34d2e64eb9c984e6eec3cbabda11c580afada?branch=rawhide to match the related rocm-comgr and rocclr changes... Reproducible: Always
Thanks for the report, I'm just catching up on bugs after some time off. I need to review a lot of the compat work, as there's a few issues needing fixes and some simplifications needed.
Not sure whether this has been fixed in the meantime... However, I noticed that /usr/lib64/llvm17/ does not contain a bin directory and hence the above command could not find the header file... Adding just the bin directory so that the path /usr/lib64/llvm17/bin exists, fixed the darktable issue for me.
Just to add... While darktable was able to compile the OpenCL kernels with the above hack of adding the bin directory, when enabling OpenCL in darktable the darkroom view of images within darktable has artefacts. I ended up disabling OpenCL again. With rocm 6.1.2 now out and darktable 4.8 due for release soon (21/06/24), hopefully, this will get fixed properly as part of those updates.
When I try to build and run ROCmExamples, I get an error clang++: error: cannot find ROCm device library; provide its path via '--rocm-path' or '--rocm-device-lib-path', or pass '-nogpulib' to build without ROCm device library I am unable to find rocm-device-libs package on Fedora 40. Is it pulled from the repository? Do I have to wait?
Apologies, the package is already installed, but I still get the error. Any ideas on how to proceed?
Solved it with export HIP_DEVICE_LIB_PATH=/usr/lib/clang/17/amdgcn/bitcode I guess some path config somewhere is wrong.
Hey we're going to just solve this by upgrading to 6.1, which doesn't have the bug.

Hi Jeremy, I have updated both my systems tonight (AMD Ryzen 7 PRO 7840U w/ Radeon 780M Graphics and AMD Ryzen 9 5900HX with Radeon Graphics), Darktable 4.8 compiles the rocm kernels and runs as expected. So all seems to be working here. Thanks a lot for sorting it (at least for this user :) )
