[gmx-users] Problem with cuda toolkit

[Shahrokh Nasseri (PhD)]

Hi Dears Gromacs Developers and users

I want to install gromacs in Fedora core 25.

My Computer Specifications are as follows:

I get the following error message:
...
 CMake Error at cmake/gmxManageNvccConfig.cmake:194 (message):
   CUDA compiler does not seem to be functional.
 Call Stack (most recent call first):
   cmake/gmxManageGPU.cmake:204 (include)
   CMakeLists.txt:590 (gmx_gpu_setup)

How should I define "CUDA_TOOLKIT_ROOT_DIR"?
Please guide me,
Shahrokh
