Hello all
I try to build blender with oidn with Nvidia gpu support.
This is my building scripts (gentoo)
Thank you for advice!
These are Gentoo specific builds which not many developers are familiar with or can easily test themselves, so not likely to get a response.
In general to help getting this solved:
include/OpenImageDenoise/config.h
to verify supported device types are enabledHi,
Tank you for answer!
oidn package builds with -DOIDN_DEVICE_CUDA=ON and cuda targets sm_86 for 3080
oidn package has /usr/lib64/libOpenImageDenoise_device_cuda.so.2.2.2 and /usr/include/OpenImageDenoise/config.h installed
blender compiled with cuda and optix? and it works fine.
What thing i missed?
/usr/include/OpenImageDenoise/config.h
blender --debug-cycles --verbose 10
trying to render with OIDN GPU supportThis is my /usr/include/OpenImageDenoise/config.h

I open blender and turn on oidn gpu checkbox
$ blender --debug-cycles --verbose 10

Does a build downloaded from blender.org work? It’s seeming less like a build problem, at least I don’t have a good guess for it.
Perhaps OIDN has an issue finding the CUDA shared library on the system. Blender uses dlopen to load it at runtime, while OIDN links against it directly.
You could attach the out of running LD_DEBUG=libs blender
and trying to rendering with OIDN GPU. The log might show it can’t find some CUDA library.
Thank you!
Looks like we found a problem
I run blender as:
LD_DEBUG=libs blender
and get log woth this errors:
80696: /usr/lib64/libOpenImageDenoise_device_cuda.so.2.2.2: error: symbol lookup error: undefined symbol: _ZN4oidn23getCutlassConvInstancesILi70EEESt6vectorINS_18CutlassConvFactoryESaIS2_EEv (fatal)
80696: /usr/lib64/libnvidia-glcore.so.550.78: error: symbol lookup error: undefined symbol: __malloc_hook (fatal)
I think problem is somwhere in my system toolchain
I will report if i found a way!
