Re: [gmx-users] gromacs-2020 build gcc/nvcc error
Dear Szilárd, Thank you so much for your help. I performed the following steps and it seems to have built successfully, I'll let you know if it does not run correctly as well. rm -r gromacs-2020/ sudo apt-get install gcc-8 g++-8 tar -xvzf gromacs-2020.tar.gz cd gromacs-2020/ mkdir build cd build CMAKE_PREFIX_PATH=/usr/:/usr/local/cuda/ cmake ../ -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON -DGMX_GPU=ON -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda/ -DCMAKE_BUILD_TYPE=release make make check sudo make install source /usr/local/gromacs/bin/GMXRC Lastly, when I was building in default and ran into trouble I like to build in debug so it gives details about building and helps me identify source of the problems or identify relevant information to pass to you so you can better help me. I appreciate your comment about not building in debugging mode, but is there a way to run release in verbose mode? When I had problems with other programs I'd usually build my first time in debugger mode so I can monitor the process, then make clean and rebuild in default. Is there a better way to do this? Once again you help was greatly appreciated, Ryan PS again a few notes (if you have time to comment on anything incorrect) I have for people needing a fix in the future and maybe myself if I do this again in a few years and forget how. CUDA version (nvcc --version) is 9.1. This is a little confusing to me because you referenced CUDA 10.1 and I completely rebuilt this computer in September 2019, so unless there is a new driver since then it should be 10.1? I grabbed the newest drivers I could find but my computer is outputting 9.1 so I guess that is my version. when building gromacs and I specify gcc/g++ verison 5, 8, or 9 it fails with the original error message regarding glibc 23.2. CMAKE_PREFIX_PATH=/usr/:/usr/local/cuda/ cmake ../ -DGMX_GPLUSPLUS_PATH=/usr/bin/g++-8 -DCUDA_HOST_COMPILER=gcc-8 -DCMAKE_CXX_COMPILER=g++-8 -DCMAKE_C_COMPILER=/usr/bin/gcc-8 -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON -DGMX_GPU=ON -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda/ -DCMAKE_BUILD_TYPE=release Do you know why this is? When I started this adventure I just had sudo apt-get install gcc g++ build-essentials. Then I used gcc-5 g++-5 and specified the version in the build step, which failed. after taking that out and running sudo apt-get install gcc-9 g++-9 it passes "CMAKE" but fails in "make". Based on your suggestions I ran the commands at the top of the email to which then worked. Would this have worked if I had just installed gcc-8 g++-8 from the beginning and ran CMAKE with no version specification?

Make sure that you cmake configuration does actually use the gcc version you intend to use. The default invocation as above will pick up the default compiler toolchain (e.g. /us/bin/gcc in your case, you can verify that by opening the CMakeCache.txt file or using ccmake) -- and I think the lack of proper AVX512 support in your default gcc 5 (which you are stil; using) is the source of the issues you report below.
