Hi,
a darktable user reported a failure during OpenCL kernel compilation. He uses AMD GPUs, one APU and a dedicated RX 9070. The message below is reported for both GPUs.
0,3099 [opencl_build_program] could not build program: CL_BUILD_PROGRAM_FAILURE
0,3100 [dt_opencl_device_init] failed to compile program `demosaic_ppg.cl'!
ROMm 7.0.1 from Debian Sid is installed. Can anyone suggest how to further debug this? Is this ROMm version too old for this hardware?

AMD generally really suck at drivers, and yes try upgrading first.
Had zero problems on arch since ages now with rocm and my 6700 xt.

It seems to be this issue, where the solution is still unknown:
opened 01:49PM - 05 Jan 26 UTC
AMD ROCm OpenCL
### Is there an existing issue for this?
- [x] I checked and did not find my is… sue in the already reported ones
### Describe the bug
I didn't get a suitable OpenCL support with an AMD gfx1200 device
### Steps to reproduce
'darktable-cltest -d opencl -d verbose' gives this output:

0.7124 [opencl_init] FINALLY: opencl PREFERENCE=OFF is NOT AVAILABLE and NOT ENABLED.
Allthough, if I build it with './build.sh --skip-build', I see these lines:
...
-- Found LLVM 21.1.8
-- Found clang compiler - /usr/bin/clang-21
-- Found clang opencl-c.h header in /usr/lib/llvm-21/lib/clang/21/include
-- Will be able to test-compile OpenCL programs. Nice.
...
Any idea what I miss?
