Hi,
I just notice that you package is depending on "amd-libopencl1 | fglrx |
fglrx-updates"
I do not understand how this can be correct.
Indeed, in Debian, fglrx and fglrx-updates do not exist at all currently
(even as virtual packages). apt-get cannot install them. So these alternatives
are void (perhaps there are here for other distributions such as ubuntu, I do
not know).
And amd-libopencl1 is an *ICD Loader*, not an ICD. It means that this is not
an OpenCL implementation but only a loader of such implementation. And
it can load any ICD installed on the machine (not just the AMD one). And
other ICD loaders can be used instead of this one (even with the AMD ICD,
ie the AMD OpenCL implementation).
So, I think that you should remove this dependency, instead use:
- "Depends: libopencl1-X.Y-1" to depends on a ICD Loader that support
OpenCL up to version X.Y. Currently, these virtual packages exists
for 1.1, 1.2 and 2.0.
Note that, in the usual case, this dependency is added automaticcaly
whith dh_shlibs due to symbol files when you have a program that links
with libOpenCL.so.1
- "Depends: amd-opencl-icd" if you wish to force the presence of the
AMD OpenCL implementation. Note that other OpenCL implementations can
be installed and OpenCL programs have to explicitly choose which ICD
they will use. The ICD loader (even the AMD one packaged in
amd-libopencl1) will choose a random one as default.
The ocl-icd-libopencl1 ICD Loader allows to choose the default ICD
with an environment variable.
If you require only a (standard) OpenCL environment, you should
depends (or recommends) only the opencl-icd virtual package, so that
other OpenCL implementations can satisfy your dependency.
Regards,
Vincent
