[gmx-users] help OpenCL build failure

[Benson Muite]

Hi,

Have you tried to use the cmake curse interface:

ccmake .. -DGMX_BUILD_OWN_FFTW=ON -DCMAKE_C_COMPILER=gcc 
-DCMAKE_CXX_COMPILER=g++ -DGMX_GPU=ON -DGMX_USE_OPENCL=ON

What version of OS X are you using? Manual indicates may need 10.10.4 or 
higher if using an AMD GPU 
(http://manual.gromacs.org/current/install-guide/index.html)
