libcuda.so.1

Accelerated Computing CUDA CUDA Programming and Performance

I’ve installed cuda on ubuntu 11.10 but when I open matlab r2011b and I type gpuDevice I get:

>> gpuDevice

Error using gpuDevice (line 22)

The CUDA driver could not be loaded. An NVIDIA GPU with CUDA driver is required. The required CUDA version

is: 4 or greater. The library name used was: libcuda.so.1. The error was: libcuda.so.1: cannot open shared

object file: No such file or directory.

I didn’t find any solution, can you help me?

Did you add the corresponding paths to $PATH and $LD_LIBRARY_PATH ?

3

No, what I have to do? Thank you.

Ok I fixed it. Now when I try to run make in the SDK folder I get:

/usr/bin/ld: warning: libnvidia-tls.so.295.20, needed by /usr/lib/nvidia-current/libGL.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libnvidia-glcore.so.295.20, needed by /usr/lib/nvidia-current/libGL.so, not found (try using -rpath or -rpath-link)

and they are both present in the folder…

what is the problem?

inside NVIDIACOMPUTE SDK folder there is a folder named “doc”. Inside this folder there is some information about missing libraries in each distribution and what to do.
