S- function does not exist

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
