I have some custom C code that gets added to a Simulink program and then programmed into a TI C2000 processor using Embedded Coder. Last week I created a C caller block that calls my C function and it worked fine. This week when I try to run the program with the C caller I get the error "No such file or directory" for many important header files. Adding the directories of these header files to the include paths just produced more errors. However, I can still run my C function by calling it from the Startup Initialization block. This indicates that the C code is fine, and the headers are fine-- It's only the C function caller that doesn't understand my code. I didn't change any settings since I had the C function caller working last week so I don't understand why it would stop working. Can anyone help me figure this out?
