Do the test run when you explicitly disable OpenCL? My guess would be that it can't find a babl extension. Make sure both the main babl lib (installs to $PREFIX/lib/libbabl-0.1.so.0, builds in babl/.libs), and babl extensions (install to $PREFIX/lib/babl-0.1/, build in extensions/.libs) are reachable in LD_LIBRARY_PATH. regards, Jan > > > > > It's also possible to run individual test manually.
