FAST on Mac

I would like to report that FAST 7 compiles just fine on Mac with the GNU FORTRAN compiler (gfortran).
I’ve compiled FAST 7.02.00d with AeroDyn 13.00.02a, InflowWind 1.02.00c and NWTCLibrary 1.07.02a; in particular the last NWTCLibrary is the one that correctly handle line overwriting when messages are printed to screen.

I’ll be glad to share more details if needed.
Happy simulations :slight_smile:


Thanks for the feedback, Stefano.

Hello Stefano,

Can you please help me with compiling s function on mac? I’m using FAST_v7.02.00d-bjj, NWTC_Lib_v2.05.02a-bjj,NWTC_Lib_v1.07.02a-mlb
and I’m trying to use the "make s function’ matlab code within fast with gfortran and matlab.
It generates precision.mod, syssubs.mod, but after i commented IFPORT in NWTC sysmatlab.f90, it doesn’t produce nwtc_library.mod and fails.
Can you please help me?


I assume you are using only NWTC Library v1.07.02 (not v2.05.02 as well).

What error message are you getting?

yes please, if you share more details I can try to compile it in my environment and see the outcome…


Thank Bonnie & Stefano for your replies. I’m sorry, I did not check the “Notify me when a reply is posted” so the delay. To answer Bonnie Jonkman’s question, yes I’m using only one version of NWTC library (1.07.02).
I must say, I have absolutely no idea of fortran coding. What I have tried to do is modify the makefile in the “build_structure” to point to MATLAB on mac.
The build_structure is obtained from .
Then, I’ve commented “USE IFPORT” wherever it was pointed and now used the “make_FAST_SFUNC.m” . In this m file, I’ve commented the “%FortranOptionsFile = ‘intelf12msvs2010shellopts.bat’;” and tried to run.
It builds “precision.mod” and “subsys.mod” and fails with the following error:

Error using mex
USE NWTC_Library


Fatal Error: Can’t open module file ‘nwtc_library.mod’ for reading at (1): No such file or directory
compilation terminated.

I’ve uploaded the make file and “make_FAST_SFUNC.m”. I might be doing something grossly wrong… Please bear with me. Thanks!
