I have just a S-Function Builder in my model which compiles successfully, but when i try to build the whole model i get the error
Changing property 'MakeCommand' is not allowed
The only "solution" is to make a new blank model and copy the S-Function Builder Block to the new model. This works for some time until it starts to throw the above error.
I would be very grateful for any help.

Could you please share your model so that I can reproduce the issue on my end.
Thanks

sorry for my late reply. I attached the simulink file.
I don't know if you would need all linked source and header files for the S-Function Builder. If so, i would try to make a minimal example since i have a really big number of source files for my S-Function Builder.
Thanks

thank you for your replay. Unfortunatelly it does not resolve my problem.
Nevertheless, I came across a workaround. The problem is that when I run the S-Function Builder and then go to Settings/Code Generation, in the grayed out "Make command" field there are additional commands next to make_tct (those used in the S-Function Builder). And Simulink does not allow additional commands there. These additional commands disappear if I briefly switch to another system target file and then back to my actual one. This has the disadvantage that I have to re-enter all non-standard settings.
