I am working with a huge simulink model that uses a lot of custom library blocks and S-functions.
But 3 of them dont work, the error is just: "Error in S-function 'modelname/subsystem/block': S-Function 'sfun_name' does not exist"
But I have a folder in my model library with the files name.cpp, name.h, sfun_name.cpp and also the simulink model of the library block.
This folder is definetely added to the path, I checked with the path command
It used to work but now simulink says these S-functions do not exist, but they do.
I tried to replace the blocks from the library but it did not help.
Does anyone have an idea about this? Or what else would I need to provide? (I am not allowed to upload any files from the model)
