Hello,

I am trying to program my dsPIC33EV starter kit using Simulink. I have my .c file that has my functions, .h file that includes my structs and extern function calls and I have a .h file from Microchip for my processor.

I am currently adding my #include "my_func.h" in header file in custom C code and src/my_func.c into source files under additional build info. my .c includes my dsPIC.h file at the top of it's code.

I have noticed that the dsPIC.h file has extern at the start of definitions which I think are being pulled by a .gld file.

i am getting this error when trying to buid:

The call to MCHP_dsPIC_stf_make_rtw_hook, during the entry hook generated the following error:
    Error(s) encountered while building custom code simulation target for model 'dsPIC33EV_Test_Can'. Fix the errors in your custom code or disable 'Import custom code' if your custom code has incompatibilities.
The build process will terminate as a result.
