When I try to run a demo Simulink model in the Aerosim Blockset, I got an error "S-Function 'sfunwmm' does not exist" I searched in the Aerosim directory and I indeed find the "sfunwmm.c" file there! I tried to re-compile it but mex command failed, I got error like "undefined reference to `InitGeomag' and some other variables.
I'm on: MATLAB R2017a Supported compiler: MW_MinGW_4_9

Hi Jack,
Try this:
  • Open Matlab as an administartor.
  • Navigate to the "sfunwmm" directory in Matlab.
  • Then type:
mex sfunwmm.c wmmutil.c -I../common
