I just installed Ubuntu 14.04 64-bit and enabled the nvidia drivers. Now I am trying to install WINE but I get the message:
nvidia-libopencl1-331 has to be removed before installing WINE (translated from Dutch). Is this a bug? Or should I proceed removing this package?
The problem here is two packages are installing the same binary file '/usr/lib/*/libOpenCL.so' without declaring a breaks/replaces or conflicts relationship between them, and so apt-get does not know to remove the other.
This either needs to be fixed in nvidia-cuda-toolkit or ocl-icd.
ocl-icd is shipping this file in ocl-icd-libopencl1 instead of ocl-icd-opencl-dev, which is against Debian policy, see https://bugs.debian.org/679228
nvidia-cuda-toolkit lists 'nvidia-opencl-dev (= 5.5.22-3ubuntu2~ppa1) | opencl-dev' among its dependencies, so as a workaround, we can help apt-get by installing ocl-icd-opencl-dev to provide opencl-dev, but we need to do it in the correct order:
sudo apt-get install nvidia-cuda-toolkit #Need to get 250 MB of archives; 774 MB of additional disk space will be used
sudo apt-get install ocl-icd-opencl-dev #this will remove nvidia-libopencl1-* and nvidia-opencl-dev
sudo apt-get install wine #Need to get 121 MB; 342 MB of additional disk space will be used.
