Dear maintainers,
I've just enabled OpenCL support in the gromacs package[1] and would
like to express a weak dependency on an OpenCL implementation, but I
have no way of doing so at the moment.
We have three packages which provide OpenCL implementations:
beignet - Intel GPUs
mesa-libOpenCL - AMD GPUs (only?)
pocl - CPU-based
Would it make sense to add a virtual provide to each of the packages
to mean the all provide a "vendor" OpenCL implementation? For example,
Provides: opencl-driver
Then, any package that makes use of OpenCL could add
Requires/Recommends/Suggests: opencl-driver
Another approach could be to create a meta package (named
opencl-drivers, for example - similar to xorg-x11-drivers) which would
depend on all vendor-specific implementations.
I guess the second approach is more fool-proof. Comments?
Hey,
yes - when we initially create the packages we actually already
discussed how to achieve this.
I'd favor the second (meta-package) approach, nothing should go wrong
if all three are installed.
I'd go even further and create an opencl package (or group?) to
install all kind of opencl packages, i.e. clinfo is a good thing to
start with.
