Re: [AMBER] Error building Amber

Sorry for the confusion. I am using clang, gfortran is installed though homebrew gcc and I have tried the cmake configuration step using gfortran7 and 10.

I am using the unmodified "run_cmake" this time, this file and the log file are both attached.

Best regards

// Gustaf

Can you post both your run_cmake script and the cmake.log file that it
creates? I can't tell from what you say above where the error is coming from.
This will also tell us what compiler you are requesting.

We generally only test clang, not gcc, so it may be that problems arise with
the latter. What is it that is driving you to gcc (if that is indeed what
you are doing? Is it lack of openmp support in Apple's clang?)
