I’m trying to compile and link a C program using the XC8 compiler. I changed from the C18 compiler and made some minor compatibility changes to the code. With C18, the code compiled and linked just fine. With XC8, compiling goes fine, but the link step fails with this error:
Error [500] ; 0. undefined symbols:
_putch(server.obj) _ENC_Init(server.obj) _ENC_WriteRegister(server.obj) _ENC_ReadRegister(server.obj)
As the compiling succeeds, I guess there are prototypes found, ergo the .h files are included okay. I guess the compiler can’t find the .c files.
The function putch is not called in my own program, but it’s called in putchar and I use that function. The functions starting with ENC_ are my own functions.
I added two paths to the “Include search path” of the XC8 toolsuite:
C:\Program Files (x86)\Microchip\xc8\v1.12\sources, where the compiler’s.cfiles are located, I believeC:\...\lib, where my own.cfiles are located.
However, I still get the error.
How can I resolve this problem?
This is the full log:
