| MCP251x.h Compile Error |

I'm trying to compile this program using MPLAB X 1.60, I can't understand as to why this isn't compiling

I put the #devices in the main am I missing something in this header file that should be there? |

I suspect that looks like the classic 'Mplab files' error.
_Only_ the main program file, must be in the 'source files' part of the Mplab project. The .h files, and included .c files, must be in the 'header files' section. If these files are put into the 'source files' part, then Mplab tries to compile them on their own. Since they lack things like #defines, they won't then compile.

| Well I just moved them, and that didn't fix the problem I still got the same error. I also tried it with the CCS compiler PCW and it also gives me the same error that Mplab is giving me |

| In MPLABX, you have to right click on the files and set them to not be compilable. There is an option for it there somewhere, perhaps in the properties of the file. |

Ya I found it, it had 2 different options...
I took a screen shot to show if this is what you ment, but going through those options still gave me compiler problems. Infact the same problem still exists. Also, if just on a thought, if I exclude that header file from the compile procedures, then wouldn't it not allow the CAN features of the MCP2515 chip to not function?
After Message Edit:
Ok I bypassed that error by also making the .c file excluded from build, but my other question still stands, if I don't include those functions in the build, then how am I going to make the functions of this chip work if the commands to run that MCP chip aren't compounded into the program? |

They are still included.
The #include in the main code _includes_ these files, and they are then compiled _as part_ of the main code.
The point about the MPLAB option is it allows you to compile things 'on their own' (this can be done if the files are setup to do this, with suitable import/export options), which are then linked to the main code, but the default CCS setup, it to do a 'single pass' compile, with everything loaded for you by the main program.
