[Pkg-erlang-devel] Bug#798255: erlang-cl: installs non-free packages

[Stepan Golosunov]

Package: erlang-cl
Version: 1.2.1-2
Severity: important

Installation of erlang-cl pulls in non-free fglrx and nvidia packages:

% apt -s install erlang-cl
NOTE: This is only a simulation!
      apt-get needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!

Even with --no-install-recommends it pulls amd-opencl-icd:

% apt -s --no-install-recommends install erlang-cl

      apt-get needs root privileges for real execution.

Manual installation of ocl-icd-libopencl1 allows to avoid the issue:

% apt -s install erlang-cl ocl-icd-libopencl1

Probably ocl-icd-libopencl1 should be listed as a first alternative
either in all libopencl* dependencies or in the first one. Currently
it is listed only in the last one:

% apt-cache show erlang-cl|grep ^Depends: 
Depends: erlang-base (>= 1:17.0-dfsg) | erlang-base-hipe (>=
1:17.0-dfsg), libc6 (>= 2.4), libopencl-1.1-1, libopencl-1.2-1,
ocl-icd-libopencl1 (>= 1.0) | libopencl1
