Try replacing DESTDIR="${D}" with install_path="${D}"/usr perhaps? That's just a guess from examining http://code.google.com/p/gpuocelot/source/browse/trunk/ocelot/SConscript . And for your first problem with CXXFLAGS, try export OCELOT_CONFIG_FLAGS="${CXXFLAGS}" That probably still leaves LDFLAGS which should probably be set in LINKFLAGS. -- binki Look out for missing or extraneous apostrophes!
