Bug#763655: boinc-amd-opencl: wrong dependencies regarding OpenCL

[Gianfranco Costamagna]

Hi Vincent and Andrei (thanks for your help in making BTS notify us the bug).

The graphic stuff is something that worries me a lot, unfortunately the delta between debian/ubuntu, and the lack of a proper dev package to link against is something that makes me having *many* difficulties in fixing the problem.
(honestly my focus now is for the upcoming freeze, and I almost gave up on this because of the lack of time to look and ask for proper help)

Unfortunately the shlibs stuff I don't think can work, since upstream doesn't link the gpu libraries, but uses dlopen to handle them.

grep dlopen client -R
./gpu_nvidia.cpp:    handle  = dlopen("libnvidia-ml.so", RTLD_NOW);
./gpu_nvidia.cpp:    cudalib = dlopen("libcuda.so", RTLD_NOW);
./gpu_amd.cpp:    callib = dlopen("libaticalrt.so", RTLD_NOW);
./gpu_opencl.cpp:    opencl_lib = dlopen("libOpenCL.so", RTLD_NOW);


so this is why we added the libraries manually in the control file.

This dlopen stuff I think is also preventing gpu to be found when the service starts before the graphic module, leading to a needs of a service reboot to correctly find the gpu stuff. (cfr lp: #933354 #1177433 #1077316)

I'm open to help, I don't really know how to properly handle the dlopen stuff

Do you have any advice for me?
the whole boinc community will benefit a lot from this bug fix, since GPUs are more powerful on computation even than CPUs :)


have many thanks for the help,
