Build error: C++ compiler produced errors. See the Build Log for further details.

Hello, I wanted to create a MEX file in MATLAB, but I couldn't do that because of the following message in the "build log":

I have previously installed visual studio 2019, and added the "cl.exe" path to my environmental variable. Moreover, Microsoft visual C++ redistributable x64 2015-2019 is currently available on my system.

Here is the added path:

What do you think about where my problem come from?

Any help would be appreciated.

Thank you

You are using MinGW64 as the C++ compiler, which is not supported by nvcc. You can config it using:

mex -setup c++

and select Microsfot Visual C++ 2019.

Hello, thank you for your help. Actually I did what you said, but the following message was shown up:

        >> mex -setup c++
        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

        	 https://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\R2018b\bin\win64\mexopts\mingw64_g++.xml' C++
        MinGW64 Compiler with Windows 10 SDK or later (C++)  mex -setup:'C:\Program Files\MATLAB\R2018b\bin\win64\mexopts\mingw64_g++_sdk10+.xml' C++

It looks like visual studio is not recognized for MATLAB as a compiler. But, when I check the control panel, I see it is installed. Can please tell me what should I do?

[Chao Luo]

Can you try dumpling the log by running this command?

mex -setup c++ -v

It should print out lines like this:

... Looking for compiler 'Microsoft Visual C++ 2019' ...

... Looking for environment variable 'ProgramFiles(x86)' ...Yes ('C:\Program Files (x86)').

... Looking for file 'C:\Program Files (x86)\Microsoft Visual Studio\Installer\vswhere.exe' ...Yes.

Here is the output. It looks like it does recognize installed VS 2019:

Hello again @Chao Luo ,

these are all the applications installed on my system:

[Chao Luo]

Seems you are using MATLAB 2018b. It does not support Visual Studio 2019 because it was not released when MATLAB 2018b was released. VS 2017 should be supported.

[moh mor]

Thank you @Chao Luo , It worked.
