[SOLVED] BOINC and libcudart.so

Hello! I have a problem regarding CUDA.

I've got an MSI NX8600GTS and NVidia drivers up and running. Compiled BOINC 6.4.5 from source (some gcc optimalization and without manager). The only problem I have is this:

28-May-2009 20:14:42 [---] Can't load library libcudart

I tried to cp the /usr/lib/libcuda.so to /usr/lib/boinc-client/libcudart.so , and so on.. but nothing helped. I read the PKGBUILD of the AUR package and many more google hit, but nothing.. could you help me out?

( I installed the aur/cuda too (2.2 version, modified the PKGBUILD on-the-fly))

Solution:
Create these folders:
sudo mkdir /usr/local/cuda
sudo mkdir /usr/local/cuda/lib

And create a symlink:
sudo ln -s /usr/lib/libcudart.so /usr/local/cuda/lib/libcudart.so

I hope this 'howto' will help someone

Re: [SOLVED] BOINC and libcudart.so

Just a guess, but do you have CUDA installed? Maybe you need the CUDA SDK at compile time of BOINC?

edit: just saw that you did have CUDA installed, sorry!
