[Debian-med-packaging] Help needed to build libhmsbeagle using OpenCL

[Andreas Tille]

Hi,

I've got the hint that libhmsbeagle only expresses its real performance
advantages when using OpenCL.  I personally do not have any experience
with OpenCL and simply added

	libpoclu-dev,
	ocl-icd-opencl-dev

as Build-Depends as well as using the configure option
"--with-opencl=/usr/include/CL" in libhmsbeagle autoconf.

This builds so far but I'm running in a failure in the test suite.  The
build log says:

OpenCL error: Unknown error from file <GPUInterfaceOpenCL.cpp>, line 111.


I found the following link

   https://groups.google.com/forum/#!topic/beast-users/vSxxJqL2zPc

with the hint to intel-opencl which translated to another Build-Depends

   beignet-dev

This enabled me to debuild on my local machine.  However, when building
using pbuilder I end up with


# cat tmp/buildd/libhmsbeagle-2.1.2+20150609/examples/tinytest/tinytest.log 
beignet-opencl-icd: no supported GPU found, this is probably the wrong opencl-icd package for this hardware
(If you have multiple ICDs installed and OpenCL works, you can ignore this message)

OpenCL error: CL_DEVICE_NOT_FOUND from file <GPUInterfaceOpenCL.cpp>, line 118.
FAIL tinytest (exit status: 255)


I assume the reason is that the chroot environment does not see any
graphics hardware.  Does this mean I need to exclude this test (which
I actually considered quite helpful) or is there any trick to get the
test working even in a chroot?

Any hint is welcome

      Andreas.
