[gmx-users] Compile Gromacs with OpenCL for MacBook Pro with AMD Radeon Pro 560 GPU

[Michael Williams]

Hi, I’ve been trying to build Gromacs 2018.3 on my MacBook Pro (in OSX 10.14.3). I saw online (https://redmine.gromacs.org/issues/2369 <https://redmine.gromacs.org/issues/2369>) that Gromacs with GPU support via OpenCL was found to work a similar computer, but I have not had any luck. Is there a way to see what settings (compiler, CMake variables, etc) were used for that build? Or if anyone has any suggestions, I’d be very grateful. Thanks for your help,

Mike

The errors that I have been getting while running “make check” look like:
