Microsoft Visual Studio 2022 set up as default C and C++ compiler in Matlab 2021a

That´s my need. It´s installed but Matlab doesn´t know that it is.

if I put: mex -setup, Microsoft visual studio doesn´t appear.

Thank you very much for helping!

What must I do in order to set Visual Studio as the Matlab C and C++ Compiler?

My default Compiler now is mingw64-g++ but I want to generate an audio plugin and it can´t be compiled, this is the message:

"Error using generateAudioPlugin

Toolchain 'MinGW64 Compiler (C++)' is not supported for generating audio plug-ins. Use one

of the following:

Microsoft Visual C++ 2017

Microsoft Visual C++ 2015."

Visual C++ is already installed in my desktop but how can I integrate it to MATLAB in order to be the compiler in use with it?

In simple words, you can not!

Plugin generation is part of the Audio Toolbox, which does not support MinGW. For plugins:

• VS 2019 was added to R2019b (appears to be missing from the error message).
• VS 2022 is planned for R2022a update 1. This and other releases subject to change.

For the latest, check the supported compilers page, including the link in the top right corner for previous releases.

I installed VS 2019. MATLAB R2021a recognized it, I set up MEX to use it as C++ compiler and it worked fine. Matlab generated the audio plugin. Thanks a lot Jimmy!

Great to hear, my pleasure!

To get MATLAB 2024a to recognise Microsoft Visual Studio Community 2022 as a compiler option for C++, I had to install 'MSVC v140 - VS 2015 c++ build tools'. Ensure you select this option when installing the 'Desktop Development with C++' workload.

This was added in R2021B Update 3. Not sure if R2021A will ever get this update. VS 2022 was release only very recently.

i can't add the microsoft visual c++ compiler as well to my 2021b version of matlab, can you help me please

[Jimmy Lapierre]

Which version of Visual C++ are you using?

[Walter Roberson]

I think I saw Youssef mention VS 2019 C++ in a different post.

Microsoft Visual Studio 2022 set up as default C and C++ compiler in Matlab 2023b

2023b does support MSVS2022, but...

If you are installing on Win10 when the "Desktop development with C++" workload is selected the default SDK is for Win11, you can uncheck that and save 2GB of space and check a Win10 SDK further down the list.

This comment is what led me to the solution to the problem of VS C++ not showing as an option when running mex -setup cpp.

I had installed VS 2022 C++ build tools, but it was not an option in MATLAB until I installed the Windows SDK. This command also helped me understand what was happening: mex -setup cpp -v.

Hi, I also encontered an issue when I ran Matlab 2023b with Microsoft Visual Studio 2022.

It told me the following error:

[GPU] : File mexcuda Line: 185

id:MATLAB:mex:Error msg:nvcc warning : The 'compute_35', 'compute_37', 'sm_35', and 'sm_37' architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning).

set_views_gpu_mex.cu

D:\MATLAB2023b\sys\cuda\win64\cuda\include\crt/host_config.h(153): fatal error C1189: #error: -- unsupported Microsoft Visual Studio version! Only the versions between 2017 and 2022 (inclusive) are supported! The nvcc flag '-allow-unsupported-compiler' can be used to override this version check; however, using an unsupported host compiler may cause compilation failure or incorrect run time execution. Use at your own risk.

I have win 11, matlab2023b, Microsoft Visual Studio 2022, CUDA 12.2 on my PC with NVIDIA GeForce RTX 4080 SUPER.

The installation of Microsoft Visual Studio 2022 is shown below:

Hi @Xu Mingquan,

in case you have not been able to resolve this yet:

The problem is that CUDA 12.2 only supports Microsoft Visual Studio 2022 versions up to 17.9.x. The solution would be to downgrade the version number (only possible with Professional) or use Microsoft Visual Studio 2017 or 2019, and specify those with mex -setup C++.

Best wishes,

Harald

[Xu Mingquan]

Hi@Harald, thanks very much for your reply.

I am not sure that I can successfully rollback the MVS to 17.9.x, and I will try.

BTW, dose CUDA 12.6 support Microsoft Visual Studio 2022 version of 17.11.x?

If so, maybe I can solve this problem by updating my CUDA to 12.6?

[Harald]

Hi @Xu Mingquan,

I would advise to use the CUDA Toolkit version that is compatible with MATLAB. For R2023b, this is 11.8 according to this table:

If you cannot roll back MVS 2022, an alternative could be to install MVS 2019.

Best wishes,

Harald

Hi@Harald,

Thanks very much for your advice.

I will try your methods.
