Why do I get an error while parsing custom code for my Simulink model?
显示 更早的评论
Hi there,
I am trying to run a simulink model in which some C caller blocks are used ( external custom c code). The Model is legacy model but I am trying to run it on Matlab 2021b
The C comoiler is MinGW64 Compiler (C)
I already updated the model advisor befoer I try to RUN the model. I received the follwoing error:
Error while parsing custom code for model 'mymodel'. Fix the errors in your custom code or disable 'Import custom code' if your custom code has incompatibilities.

Advice and input very welcome, thanks!

It looks to me as if MinGW is not recognizing _cdecl as a keyword. It is not part of C itself, it is a Microsoft extension (that is also implemented by several other companies for Microsoft compatibility.)
It looks to me as if there is a command line option that controls recognition of _cdecl

Is this error specific to your custom code? You could try an example model to make sure this isn't some compiler configuration issue.

It could be an issue with the code parser. Are you able to share your code? I'd recommend contacting technical support, just in case this is a bug: https://www.mathworks.com/support/contact_us.html

We have a very similar problem with R2018b and C Caller
all work on my colleague machine and not anymore on mine....
