Dear Szilárd, Thank you for your quick response. You are correct, after issuing sudo apt-get install gcc-9 g++-9 CMake was run with:
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=Debug However now I'm getting an error in make make VERBOSE=1 error: [ 25%] Building CXX object src/gromacs/CMakeFiles/libgromacs.dir/nbnxm/kernels_simd_2xmm/kernel_ElecEwTwinCut_VdwLJEwCombGeom_F.cpp.o In file included from /home/rlwoltz/protein_modeling/gromacs-2020/src/gromacs/simd/impl_x86_avx_512/impl_x86_avx_512.h:46:0, from /home/rlwoltz/protein_modeling/gromacs-2020/src/gromacs/simd/simd.h:146, from /home/rlwoltz/protein_modeling/gromacs-2020/src/gromacs/nbnxm/nbnxm_simd.h:40, from /home/rlwoltz/protein_modeling/gromacs-2020/src/gromacs/nbnxm/kernels_simd_2xmm/kernel_ElecEwTwinCut_VdwLJEwCombGeom_F.cpp:49: /home/rlwoltz/protein_modeling/gromacs-2020/src/gromacs/simd/impl_x86_avx_512/impl_x86_avx_512_util_float.h: In function ‘void gmx::gatherLoadTransposeHsimd(const float*, const float*, const int32_t*, gmx::SimdFloat*, gmx::SimdFloat*) [with int align = 2; int32_t = int]’: /home/rlwoltz/protein_modeling/gromacs-2020/src/gromacs/simd/impl_x86_avx_512/impl_x86_avx_512_util_float.h:422:28: error: the last argument must be scale 1, 2, 4, 8 tmp1 = _mm512_castpd_ps( ^ /home/rlwoltz/protein_modeling/gromacs-2020/src/gromacs/simd/impl_x86_avx_512/impl_x86_avx_512_util_float.h:424:28: error: the last argument must be scale 1, 2, 4, 8 tmp2 = _mm512_castpd_ps( ^ src/gromacs/CMakeFiles/libgromacs.dir/build.make:13881: recipe for target 'src/gromacs/CMakeFiles/libgromacs.dir/nbnxm/kernels_simd_2xmm/kernel_ElecEwTwinCut_VdwLJEwCombGeom_F.cpp.o' failed make[2]: *** [src/gromacs/CMakeFiles/libgromacs.dir/nbnxm/kernels_simd_2xmm/kernel_ElecEwTwinCut_VdwLJEwCombGeom_F.cpp.o] Error 1 CMakeFiles/Makefile2:2910: recipe for target 'src/gromacs/CMakeFiles/libgromacs.dir/all' failed make[1]: *** [src/gromacs/CMakeFiles/libgromacs.dir/all] Error 2 Makefile:162: recipe for target 'all' failed make: *** [all] Error 2 after doing a 1 hour google I found discussions saying that the error (Makefile:162: recipe for target 'all' failed) is too vague with no general solution. I found fixes for headers and other files for other programs but not fixes for this file. The fix linked below is for gromacs-2018 and a different file but the general problem seems to suggest it still is a gcc/g++ version compatibility error correct? Any suggestions for this error? https://redmine.gromacs.org/issues/2312 Thank you so much, Ryan PS Just to document for anyone else going through what I did for Gromacs-2020 these were my steps. sudo apt-get install gcc g++ cmake ../ -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON -DGMX_GPU=ON I then received multiple errors complaining about nvcc/C++ incompatibility. After researching found errors for previous gromacs versions suggesting to use gcc-5 (but as you suggested this error has been patched). sudo apt-get install gcc-5 g++-5 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 -D_FORCE_INLINES=OFF Received different error described in previous email and solved with your suggested solution. The key might be to specifically install latest version number i.e. sudo apt-get install gcc-X g++-X (with X being the largest number available).
