I have a problem when I try building a model with C caller block in it for Simulink Real Time target (slrealtime.tlc).
The function implemented in the C code is "not declared" even if the same model is built successfully with the old simulink real time slrt.tlc (R2019a). As soon as I remove the C caller Block the exe file is generated for my Hardware in the loop machine.
P.S. I had the same problem with R2021a release but it works when I try builing the model for a generic target (grt.tlc)
Anybody has any idea how to fix it?
Thank you for your help

Hi Daniel,
Have you checked these suggestions when updating to R2020b and later? There's a number of differences in Simulink Real-Time between R2020a & earlier and R2020b & later which need to be taken into account in your code.
I hope this is helpful!

Hi Dimitri,
thank you for your answer. Yes you are right, many things changed from the previuos release. I just fixed this problem:
I had to rename the file extension of the file called by the C Caller Block from .c to .cpp and everything works as before ( with the old simulink real time).....It seems like the C++ compiler of the new Simulink Real time doesn't accept the .c extension file....it is weird but that was I have experienced.
I hope this can be helpfull to somebody else
