Simulink Compiler Error for S-Function

Question

0 个投票

I am trying to compile a Simulink s-function in Matlab 2016b and I am receiving the following error:

An installed compiler was not detected. Certain simulation modes, as well as host-based coder builds require that a compiler be installed. Please install one of the supported compilers for this release as listed at:
http://www.mathworks.com/support/compilers/R2015b/win64.html
MATLAB must be restarted after the compiler is installed.

I have two compilers installed that are compatible with this package, MinGW and Microsoft Visual Studio 2017. When I type mex -setup into the Matlab command prompt I get the following output:

MEX configured to use 'Microsoft Visual C++ 2017 (C)' for C language compilation.
Warning: The MATLAB C and Fortran API has changed to support MATLAB
   variables with more than 2^32-1 elements. In the near future
   you will be required to update your code to utilize the
   new API. You can find more information about this at:
   http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.
To choose a different C compiler, select one from the following:
MinGW64 Compiler (C)  mex -setup:'C:\Program Files\MATLAB\R2015b\bin\win64\mexopts\mingw64.xml' C
Microsoft Visual C++ 2017 (C)  mex -setup:C:\Users\e0446159\AppData\Roaming\MathWorks\MATLAB\R2015b\mex_C_win64.xml C
To choose a different language, select one from the following:
 mex -setup C++ 
 mex -setup FORTRAN

Does anyone have any suggestions as to potential next steps? The Simulink file is rather complex and cannot be upgraded/downgraded to a different Matlab version. Thank you in advance for your help.

Ted Rimstidt: which MinGW release do you have installed? You would need MinGW 5.3 for R2017b for Simulink code generation, except that MinGW is not supported for Simulink Real Time.

I installed the MinGW 5.3 add-on available for 2017b. As far as Simulink Real Time is concerned I don't fully understand if that's needed for what I typically have done in the past. I'm not building real-time model dlls as far as I know. I was thinking the process I am doing was more related to building Simulink S-functions. Do I potentially need Microsoft Visual 2013 or higher?
