I have been packaging a few OpenCL libraries lately. For most of them,
the test suite can only be run from an OpenCL capable machine.
Since OpenCL can also run on the CPU it should be possible to get the
capability by pulling in a package that provides an CPU based
opencl-idc, e.g. pocl-opencl-icd.
You are correct. I guess *any* -icd package should do if we want to
remain generic enough?
Well, I pointed out pocl-opencl-icd because it is in "main" and it
provides a CPU based implementation that seems to be cross platform.
Not sure how well it implements the specs though.
Pulling in non-free packages (like amd or nvidia -icd") during the build
might force you to put the package into "contrib" and these packages
have very limited hardware support.
This expression gives me the number of platforms:
clinfo | head -n1 | sed -e 's/.*[^0-9]\([0-9]\+\)[^0-9]*$/\1/'
How do I create the override_dh_auto_test out of this?
I apologize in advance for my modest bash skills.
Less bash, more make:
<<<<<<<<<<<<<<<<
num_opencl_platforms := $(shell clinfo | head -n1 |\
sed -e "s/.*[^0-9]\([0-9]\+\)[^0-9]*$$/\1/")
ifeq ($(num_opencl_platforms), 0)
override_dh_auto_test:
@echo "No OpenCL platform available, skipping test"
else
override_dh_auto_test:
dh_auto_test
endif
