Troubleshooting

A catalogue of installation and usage tips & tricks.

Importing and running

1. can't load .so/.DLL for: libcudart.so or dyld: Library not loaded: @rpath/libcudart.dylib

   GHC can not find where you have installed the CUDA libraries. Make sure you have correctly set your PATH and LD_LIBRARY_PATH as described in installation.

2. ./Data/Array/Accelerate/CUDA.hs:145 (unhandled): CUDA Exception: invalid argument

   There was a problem with the autoconf setup for the CUDA bindings package that struck some machines (at least Mac OS X 10.8 x86_64). Please update to at least cuda-0.5.0.1.

3. Example programs take 100% CPU and graphics are unresponsive

   You might not have correctly built the accelerate-examples package with a high-performance backend such as CUDA. Try enabling one explicitly with cabal install -fcuda accelerate-examples. See also the discussion at issue #82.
