You seem to instead want a way to "debug" build-time issues. A debug build will not help in that, you will not get additional information about compilation issues. You can run "make VERBOSE=1" (regadless of the build type) with makefiles generated by cmake to get a detailed information on the commands executed during the build, but unless you have a compile- or link-time failure that you want to track down that sea of output is generally not too useful.

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.

Re: [gmx-users] gromacs-2020 build gcc/nvcc error
Hi Ryan, The issue you linked has been worked around in the build system, so my guess is that the issue you are seeing is not related. I would recommend that you update your software stack to the latest version (both CUDA 9.1 and gcc 5 are a few years old). On Ubuntu 18.04 you should be able to get gcc 8 through the package manager. Together with upgrading to the latest CUDA might well solve your issues. Let us know if that worked!

[gmx-users] gromacs-2020 build gcc/nvcc error
Hello Gromacs experts, First things first, I apologize for any double post but I just joined the community so I'm very new and only found 1-2 posts related to my problem but the solutions did not work. I have been doing MD for about 6-months using NAMD but want to also try out Gromacs. That being said I am slightly familiar with CPU modeling programs like Rosetta, but I am totally lost when it comes to fixing errors using GPU accelerated code for CUDA. I did find that at one point my error was fixed for an earlier version of Gromacs but Gromacs-2020 may have resurfaced the same error again, here is what I think my error is: https://redmine.gromacs.org/issues/1982 I am running Ubuntu 18.04.03 LTS, and gromacs-2020 I did initially have the gcc/nvcc incompatible but I think installing and using gcc-5/g++-5 version command in cmake has fixed that issue. I have a NVIDIA card with CUDA-9.1 driver when I type nvcc --version. my cmake command is as follows: CMAKE_PREFIX_PATH=/usr/:/usr/local/cuda/ cmake ../ -DGMX_GPLUSPLUS_PATH=/usr/bin/g++-5 -DCUDA_HOST_COMPILER=gcc-5 -DCMAKE_CXX_COMPILER=g++-5 -DCMAKE_C_COMPILER=/usr/bin/gcc-5 -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON -DGMX_GPU=ON -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda/ -DCMAKE_BUILD_TYPE=Debug (I did try adding -D_FORCE_INLINES= based on the link above in my running command but it did not work). I did look at the error log but it is way over my head. I have in addition deleted the CMakeCache.txt file or the unpacked Gromacs and re-unzipped it to restart the cmake process to make sure it was starting "clean". Is there any additional information I could provide? Does anyone have a suggestion? Again I'm sorry if this is a duplicate, everything I found on other sites was way over my head and I generally understand what is going on but the forums I read on possible solutions seem way over my head and I'm afraid I will break the driver if I attempt them (which has happened to me already and the computer required a full reinstall). here is last lines from the build: -- Found HWLOC: /usr/lib/x86_64-linux-gnu/libhwloc.so (found suitable version "1.11.6", minimum required is "1.5") -- Looking for C++ include pthread.h -- Looking for C++ include pthread.h - found -- Atomic operations found -- Performing Test PTHREAD_SETAFFINITY -- Performing Test PTHREAD_SETAFFINITY - Success -- Adding work-around for issue compiling CUDA code with glibc 2.23 string.h -- Check for working NVCC/C++ compiler combination with nvcc '/usr/local/cuda/bin/nvcc' -- Check for working NVCC/C compiler combination - broken -- /usr/local/cuda/bin/nvcc standard output: '' -- /usr/local/cuda/bin/nvcc standard error: '/home/rlwoltz/protein_modeling/gromacs-2020/build/gcc-5: No such file or directory ' CMake Error at cmake/gmxManageNvccConfig.cmake:189 (message): CUDA compiler does not seem to be functional.
