Problems with Mac installation

GROMACS version: 2020.3
GROMACS modification: No

Hi everyone,

I’m trying to install GROMACS on my MacBook Pro running macOS Mojave 10.14.6. Instead of using clang, I installed the Intel compiler as suggested by the installation guide with this command:

> cmake .. -DGMX_BUILD_OWN_FFTW=ON -DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc

But when I use cmake, here’s the output I get:

The most glaring issues I see are the one about the Intel compiler not supporting OpenMP and the one about not finding Atomic Operations. How can I fix this?

Thank you!

I am surprised that Intel does not supports OpenMP.

Please try followings, let me know if it helps.

  • Source intel complier environment (adjust path accordingly)
source /path-to-intelcompiler/mac/bin/compilervars.sh intel64 
  • Configure with MKL and explicit installation path
cmake .. -DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc -DGMX_FFT_LIBRARY=MKL  -DCMAKE_INSTALL_PREFIX=/path-to-installation/ 

I installed GROMACS on a separate computer using Intel as well, but the OpenMP error didn’t pop up. And Intel should support OpenMP just from a quick Google search. Maybe it has something to do with the computer I’m using? Not sure, but I’ll definitely try out your suggestions! Thank you so much!

Update: unfortunately, the output came up with the same issues (no OpenMP support even though there should be and atomic operations not found):

Here are the specs for my MacBook if it helps:

I appreciate your help!
