GPU code generation failed with the error 'emlc:compilationError'

When using GPU Coder, I encountered issues with the following environment configuration:

- **GPU Version**: NVIDIA RTX A2000 (Compute Capability 8.6, Ampere Architecture).

- **MATLAB Version**: R2023b.

- **CUDA Toolkit Version**: 11.8.

- **Visual Studio Version**: 2022 (with "Desktop Development with C++" component installed).

When I test

I looked throught the answers about 'emlc:compilationError' and "Invalid CUDA device", and see the answer in GPU coder :basic Code Generation failed - MATLAB Answers - MATLAB Central, its issue is caused by a MATLAB version that is too low. However, after reviewing the relevant settings, my MATLAB version should support CUDA 11.8 and VS2022. So, what could be the problem?

PS: I installed cuDNN 8.9 (cudnn-windows-x86_64-8.9.7.29_cuda11-archive) and set the system environment variable `NVIDIA_CUDNN` to: `C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8`. Why does the cuDNN Environment still show as failed here?

[Joss Knight]

It might be worth noting that cuDNN is installed separately from the CUDA toolkit and isn't installed in the same location, so it doesn't make sense to make NVIDIA_CUDNN point to the toolkit location.

Hi Shi,

Can you make sure you are using Visual Studio as the MEX C++ compiler by running "mex -setup C++"? GPU Coder only support Visual Studio, not MinGW.

Since you are using Visual Studio 2022, it is very likely the version of Visual Studio 2022 is not supported by CUDA 11.8. CUDA 11.8 only support Visual Studio with __MSC_VER from 1910 to 1939.

To find out __MSC_VER, you can open "Developer Command Prompt for VS 2022", and type "cl.exe", it should print message like this:

C:\Program Files\Microsoft Visual Studio\2022\Professional>cl.exe
Microsoft (R) C/C++ Optimizing Compiler Version 19.39.33523 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

19.39 is the __MSC_VER of this Visual Studio.

Latest Visual Studio 2022 is newer than 19.40, and it is not supported. You can try Visual Studio 2019 if it is possible.

[Shi]

Thank you very much for your reply! I have switched the C++ compiler to VS 2019, but the issue remains unresolved. The detailed process and error logs are as follows.

ninja: build stopped: subcommand failed.           

Seeking any further suggestions! Really appreciated!

The issue has finally been resolved!

The reason was that the external compiler, Visual C++, could not access paths containing Chinese characters (the gpuSimpleTest was by default stored in the user folder). I finally solved this problem by modifying the username path (the user folder cannot be simply rename. If needed, please find a solution on your own). Also, the C++ compiler should be switched to Visual Studio 2019.

While MATLAB currently supports running code in most Chinese paths, there are still some issues when introducing external compilers. As a user in the Chinese community, I hope similar issues can be resolved in the future.

Many thanks to Luo, Roberson and Knight for their answers !

@chao luo: I have a similar issue. Would it be possible to share the download link for VS 2019? Unfortunately the microsoft website is confusing and I wasn't able to locate it
