libcuda.so not found

Recently I installed the PGI compiler on Linux according to the PGI installation guide and everything goes well during the installation. But after that some errors occur when I run the commend pgaccelinfo -v. Shown below:

libcuda.so not found
libOpenCL.so not found
libcoi_host.so not found
No accelerators found.
Check that you have installed the CUDA, OpenCL or COI libraries properly
Check that your LD_LIBRARY_PATH environment variable points to the CUDA, OpenCL or COI runtime installation directory

I’m sure I accpet to install the CUDA toolkit during the compiler installation. And the problem still exist even I reinstall the PGI compiler.In addition, I checked the LD_LIBRARY_PATH environment virables but unfortunately, I found this environment virable did not exist.
So what can I do for it?
Thanks[/code]

Hi yxiang12744,

The OpenACC Toolkit includes all necessary tools to build your binary. To run however, you need to separately install the appropriate device driver for your system.

You can find NVIDIA drivers here: http://www.nvidia.com/Download/index.aspx?lang=en-us

Hope this helps,
