I was trying to fix missing `clcfunc.h` header by attempting to downgrade `libclc-dev` to `libclc-15-dev` to resolve the missing header but it breaks the whole Mesa OpenCL driver!

Does anyone know how to solve this problem please?

Thank you in advance,

Best regards,
caja

Is your GPU detected if you enable RUSTICL?
export RUSTICL_ENABLE=radeonsi
export RUSTICL_FEATURES=fp64
clinfo

Newer Mesa releases should have this enabled by default. Clover is a deprecated OpenCL implementation and was essentially unusable for almost all BOINC projects.

With RUSTICL you have a chance to run some projects (primegrid, einstein...). Unfortunately, the asteroids app doesn't work with RUSTICL yet.
Anyway, those implementations are typically about 30% slower "IF" they work at all.

For GPU-based projects and optimal performance, installing AMD ROCm drivers is strongly recommended. The issue is that Ubuntu 24.04 no longer appears to be supported.
https://www.amd.com/en/support/downloads/drivers.html/graphics/radeon-pro/radeon-pro-wx-x200-series/radeon-pro-wx-3200.html
if ROCm is not an option because pre-RDNA cards are poorly supported, RUSTICL is the best alternative on Linux.

Thank you for your concise answer. I have tried to export the variables you suggested, and it looks the same:

So, downgrading the system to a version that still supports ROCm doesn't make sense, because this GPU doesn't have ROCm support anyway. Have I understood that correctly?

Ok, then the AMD Radeon Pro WX 3200 likely isn’t supported by Rusticl (or with your Mesa version). Since GCN 3 works, GCN 4 should also work. It’s probably just a matter of enabling the device ID, as this isn’t a typical gaming card, but unless you know how to debug and compile Mesa, I wouldn’t go this route.

then you have only 3 options left
• Downgrade to Ubuntu 22.04.3, which does appear to have ROCm support
• Upgrade Mesa to 26.0 0 (you may need to install it manually), there's a chance of better support for older cards
• Use Windows 10 or 11
