Codegen Fails Without Showing any Errors

Matlab 2022a:

The Matlab Coder Report Viewer indicated that I have a build error:

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

But when I view the Build Logs it doesn't contain any errors. It just ends like this:

...

[18/260] cl /c /Zc:__cplusplus /Zp8 /GR /W3 /EHs ... \fuelopt_nlp.obj

fuelopt_nlp.cpp

ninja: build stopped: subcommand failed.

My only guess is that the build ninja is preventing the error message from being displayed. Is there a way to get verbose build logs or disable the ninja?

Could you please let us know if you are able to build portable code (library/dll) ?

If you are using "codegen" then you can create the configuration using coder.config('lib') / coder.config('dll')

Using coder.config('lib') I was able to get a build log showing the errors. However these errors are a result of not building for MEX because of MEX-specific compiler flag MATLAB_MEX_FILE I use in my project. It's not clear to me how I would add that compiler flag to the coder configuration.

You can use coder.updateBuildInfo to add additional flags to target compiler: Update build information object RTW.BuildInfo - MATLAB coder.updateBuildInfo - MathWorks India
