In R2022a, a new feature was introduced to make it easy to debug custom code. You can refer to this page: https://www.mathworks.com/help/simulink/ug/debug-custom-code.html

If you are still in a release before R2022a, it is possible to debug in Visual Studio, but the workflow is not as straightforward. For instructions on how to do that, refer to the documentation for your specific release. For example, here are the instructions for R2021b: https://www.mathworks.com/help/releases/R2021b/simulink/ug/integrate-ccode-ccaller.html#mw_d8fef0fd-6efd-471c-84c1-5ef9ddaf65a2

Hi,

I have tried debug a ccaller block with R2022a and VS2022, but when the debugger starts to open, i got the following error

"Error occurred when launching external debugger.

Caused by: Call to service method "attach" failed.

Message: Excepción de HRESULT: 0x8971001E

Source: msvcservice

HelpLink: None"

Some times it "works" supossedly because this error does not shows up, but then in VS there is no code to put breakpoints. Am I missing something?

I have the correct compiler attached to matlab, using "Microsoft visual C++ 2022 (C)".

Any help is very welcome

I am experiencing the exact same error and would appreciate very much any hint to solve it.

I had the same error, deinstalling other languages and setting Visual Studio to only English solved the problem for me.
