Mex MinGW64 problem

Hello,

i have a problem with MinGW64 Compiler (c).

Matlab Version: R2018B

Issuse:

I am trying to build an s-function by compiler MinGW64, in Matlab is everything set correctly, but still, I am receiving the error that the compiler dost not exist. I already try to reinstall MinGW64 but It did not help.

Matlab command window:

>> mex -setup
MEX configured to use 'MinGW64 Compiler (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. You will be required
	 to update your code to utilize the new API.
	 You can find more information about this at:

To choose a different C compiler, select one from the following:
MinGW64 Compiler (C)  mex -setup:C:\Users\z637879\AppData\Roaming\MathWorks\MATLAB\R2018b\mex_C_win64.xml C
Microsoft Visual C++ 2015 (C)  mex -setup:C:\app\MATLAB\R2018b\bin\win64\mexopts\msvc2015.xml C
Microsoft Visual C++ 2017 (C)  mex -setup:C:\app\MATLAB\R2018b\bin\win64\mexopts\msvc2017.xml C

To choose a different language, select one from the following:
 mex -setup C++ 
 mex -setup FORTRAN

build log:

 No supported compiler was found. You can install the freely available MinGW-w64 C/C++ compiler; visit https://www.mathworks.com/help/matlab/matlab_external/install-mingw-support-package.html. For more options, visit https://www.mathworks.com/support/compilers.

Which version of mingw64 do you have installed? Your release does not support the latest version.

Hi,

I installed: MinGw_Compiler_R2018b (1462267954), so i dont now exactli whitch version i have, but befor installation i had to fix some bug becuase the installation did not work. For bug fix i used this topic:https://www.mathworks.com/support/bugreports/1741173

[Jan Kopacka]

so the version is 6.3

[Walter Roberson]

Would you just happen to be trying to build for Simulink Real Time? MinGW 6.3 is supported in R2018b for all Simulink related compiling except Simulink Real Time.

[Jan Kopacka]

No, I need to build from my C file the function for simulink :)

Hey Jan.

Have you solved your problem?

We did run into the same behaviour.

Best Regards
