Hi everyone, Just a note to say that I've now successfully managed to build pyopencl on debian lenny amd64 (actually core2 duo) with the AMD/ATI drivers. This machine has no suitable graphics card, so I'm using the AMD/ATI drivers for the CPU part for testing. I first downloaded both the driver and SDK archives, uncompressed them, and copied the driver libraries from arch/x86_64/usr/lib64/ to the main SDK lib directory, finally setting LD_LIBRARY_PATH to include that dir. Building pyopencl was more tricky, and I eventually did something like: - ensure I had the libboost*1.35.0 packages installed, rather than 1.34 (using package manager) - (already had numpy) - python configure.py ... with various options. I don't recall exactly, but I ended up realising that siteconf.py held the options so if things didn't work edited it by hand, leading to: BOOST_INC_DIR = [] BOOST_LIB_DIR = [] BOOST_COMPILER = 'gcc42' BOOST_PYTHON_LIBNAME = ['boost_python-gcc42-mt-1_35-py25'] BOOST_THREAD_LIBNAME = ['boost_thread-gcc42-mt-1_35'] CL_TRACE = False CL_ENABLE_GL = False SHIPPED_CL_HEADERS = False CL_INC_DIR = ['SOMETHING/opencl/ati-stream-sdk-v2.0-beta4-lnx64/include/'] CL_LIB_DIR = ['SOMETHING/opencl/ati-stream-sdk-v2.0-beta4-lnx64/lib/x86_64/'] CL_LIBNAME = ['OpenCL'] CXXFLAGS = [] LDFLAGS = [] (note that I've put 'SOMETHING' where a more complex path really was, but it should still be on one line not two) - I tried 'make install', but wanted to install locally (home directory), and some 'ctags' command failed, so in the end used: python setup.py build python setup.py install --home=$DIR (for some value of $DIR !) where I'd made $DIR beforehand - I set PYTHONPATH to $DIR/lib/python (I think!) - CRITICALLY (?) I cd'ed away from the pyopencl directory (!) and then "python -c 'import pyopencl'" worked without a problem :D That was fun ;) I'm hoping that a pyopencl package might appear in debian shortly... Actual questions to follow shortly ;) -- Neil
