Try: LD_LIBRARY_PATH=. ./CUDA-Z-0.7.189.run See if it finds that lirary then. > francesco@gig64:~/tmp$ ls > CUDA-Z-0.7.189.run libXrender.so.1 > francesco@gig64:~/tmp$ ./CUDA-Z-0.7.189.run > CUDA-Z 0.7.189 Container > Starting CUDA-Z... > /home/francesco/tmp/CUDA-Z-a3db-49bf-8cb7-059d/cuda-z: error while loading > shared libraries: libXrender.so.1: cannot open shared object file: No such > file or directory > francesco@gig64:~/tmp$ > > Actually the required lib is available, as shown by my copy into tmp.

I see a package in Debian named 'nvidia-cuda-toolkit'. Does that include that you were looking for? I guess the bandwidthtest isn't built normally. -- Len Sroensen -- To UNSUBSCRIBE, email to debian-amd64-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
