GROMACS version: GROMACS modification: Yes/No Hi, I installed CUDA 10.1 drivers in GPU enabled machine and tried to install gromacs 2018.1 in GPU compitable using following command. cmake … -DGMX\_GPU=ON -DCMAKE\_CXX\_COMPILER=g+±7 -DCMAKE\_C\_COMPILER=gcc-7 -DCUDA\_TOOLKIT\_ROOT\_DIR=/usr/local/cuda-10.1 But it gives following error. I tried gcc-7 and gcc-9 Installation was not successful in both cases. – Check for working NVCC/C compiler combination – Check for working NVCC/C compiler combination - broken CMake Error at cmake/gmxManageGPU.cmake:289 (message): NVCC/C compiler combination does not seem to be supported. CUDA frequently does not support the latest versions of the host compiler, so you might want to try an earlier C/C++ compiler version and make sure your CUDA compiler and driver are as recent as possible. Call Stack (most recent call first): CMakeLists.txt:582 (gmx\_gpu\_setup) – Configuring incomplete, errors occurred! See also “/root/gromacs-2018.1/build/CMakeFiles/CMakeOutput.log”. See also “/root/gromacs-2018.1/build/CMakeFiles/CMakeError.log”. You have changed variables that require your cache to be deleted. Configure will be re-run and you may have to reset some variables. The following variables have changed: CMAKE\_C\_COMPILER= gcc-7 CMAKE\_CXX\_COMPILER= g+±7 – Generating done – Build files have been written to: /root/gromacs-2018.1/build Can any body help Thanks, sainitin
