Hi, I’ve pasted below an email that I sent to this list a few months ago after
receiving some help building GROMACS on my MacBook with AMD GPU. This was with
a slightly earlier version of GROMACS but it may still be helpful.

Hi again Szilárd, I just wanted to follow up on my last message. I found no
difference after modifying the file you suggested in Gromacs 2018.5. However, I
did find that if I compiled the unmodified 2018.5 code and ran “make install”
then (after sourcing the GMXRC file) I could run "./gmxtest.pl all" in the
regression test folder and all of those tests passed. (It doesn’t seem like
that runs all of the same tests as “make check”, though). In any case, even the
tests that fail if doing “make check” directly after compiling only fail
because a header file couldn’t be found; none of the tests failed due to
returning a value outside of tolerance. Also, mdrun seems to be utilizing the
GPU as expected. For the record, here is the cmake command I used:
cmake ..
-DCMAKE_INSTALL_PREFIX=/Users/michael/.local/apps/gromacs-2018.5-apple-clang-omp-ocl
-DCMAKE_LIBRARY_PATH=/Users/michael/.local/lib
-DCMAKE_INCLUDE_PATH=/Users/michael/.local/include
-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++
-DCMAKE_C_FLAGS="-Xpreprocessor -fopenmp -lomp -L/Users/michael/.local/lib
-I/Users/michael/.local/include" -DCMAKE_CXX_FLAGS="-Xpreprocessor -fopenmp
-lomp -L/Users/michael/.local/lib -I/Users/michael/.local/include"
-DGMX_FFT_LIBRARY=fftw3 -DGMX_GPU=ON -DGMX_USE_OPENCL=ON
My $HOME/.local directory is the prefix I used to install appropriate versions
of hwloc (1.11.12), libomp (7.0.1), and fftw3 (3.3.8) that I compiled with the
system’s default clang (in OSX 10.14.3, Mojave). Thanks again,
Mike
