You can then use GEGL_DEBUG=opencl env var to get some info. after building GEGL, you can just run 'make check' in top directory to run the entire test suite. Also most test subdirectories have their own Makefile with 'check' target. Not all test phases touch OpenCL paths, the most important is probably 'compositions' so you can just do cd tests/compositions make check The situation on my TURKS GPU is that all but 2 composition tests pass (after applying the patches I sent yesterday) It's also possible to run individual test manually. There is a a binary in .libs, but it needs access to operation libs. You need to do: GEGL_PATH="./operations" \ LD_LIBRARY_PATH="$LD_LIBRARY_PATH:./gegl/.libs/" ./bin/.libs/gegl and then provide path to a test .xml. It displays the result on the screen, -o allows you to set output file (png). You can then compare the png file with reference in tests/*/reference using graphicsmagick (or imagemagick): gm compare or gm composite -compose Difference if you have multiple opencl implementations available you can use GEGL_USE_OPENCL env var to select device type. the accepted values are 'yes' (default), 'no'(hard-disable), 'cpu', 'gpu', 'accelerator' HTH, let me know if you have further questions Jan > > Thanks in advance! > Bruno > -- Jan Vesely <jan.ves...@rutgers.edu>
