Compiling problem
 

I am using MPLab v.7.31 for vex. I have all the requirements. The sad thing is the compiler is complaining that the "Coff file format for ifi_library.o is out of date". I changed the library file to Vex_alltimers: still not working. NEED HELP!!! Thank you.

Re: Compiling problem
 

Your mcc18 compiler is too new.
The ifi libraries require nothing newer or more recent than version 2.4.
(Thanks Mike)

Mark,

I think you mean "nothing newer" than 2.40...

Alex,

I don't think that the older compilers are available from Microchip. However, you can order a programming CD from IFI for $50

The vex code requires a minimum of MPLab IDE v. 6.62. The other computer we have does not have a lower version.

Sorry we weren't clear.
Your MPLAB version is fine, but there is a separate C compiler MPLAB calls that's responsible for your troubles. The Vex code requires an older version of the Microchip C18 compiler than the one you are attempting to use, and won't work with the latest version.

From http://www.vexlabs.com/vex-robotics-downloads.shtml
Look for the file C:\mcc18\README.C18 on each of your computers, open and read it using Wordpad or similar. It will tell you the C compiler version on the second line.
