Wierd compiler problem

[magvitron]

Hi,
I was playing with PIC18f25k80 's ECAN module. Generated a code from application maestro and then compiled with the C-18 compiler. Everything else compiles but the CAN.c wont. It shows the below error. I have changed the PIR3 registers which the can interrupt registers supposed to have of the default IC that the application maestro generated code to the pic that i have, the pic have those to PIR5 and PIE5. I have included the files and everything and whne I compile it , it shows the below error.

OK!!

You need to edit the "can.c " It seems as the definitions for the pic18f25k80 are overwritten causing untold pain..

This code has been modified for use in the hi-tech... XC8 compiler... You need to go through the definitions one by one as the CAN seems to be hard written to a different device.... I have rem'd out the definitions and now the TRISB is warning me...

Re-Edited..

Just change all the definitions in CAN.C to PIR5 and PIE5 and it works ok....

Changed the bits according to the spec of the xc8 compiler, liek Still showing errors with Xc8 compilers too, with 16 bit shifts, unknown pragmas etc.
