I added 3 symlinks:
$ sudo find / -iname libOpenCL.so -exec ls -l {} \;
lrwxrwxrwx 1 root root 45 août 30 12:51
/usr/lib/x86_64-linux-gnu/libOpenCL.so ->
/usr/lib/i386-linux-gnu/libnvidia-opencl.so.1
lrwxrwxrwx 1 root root 45 août 30 12:48 /usr/lib/libOpenCL.so ->
/usr/lib/i386-linux-gnu/libnvidia-opencl.so.1
lrwxrwxrwx 1 root root 45 août 30 12:51
/usr/lib/i386-linux-gnu/libOpenCL.so ->
/usr/lib/i386-linux-gnu/libnvidia-opencl.so.1
Unfortunately it doesn't help, and darktable doesn't give much information
about where it looks for libOpenCL!
[opencl_init] trying to load opencl library: '<system default>'
[opencl_init] could not find opencl runtime library 'libOpenCL'
