I just setup a clean virtual machine with Windows XP Professional sp2. I ran Windows Update, installed MPLab 8.0, and installed C18 3.15 Student Edition.

Here are the errors I'm getting:
MPLAB C18 v3.15 (demo)

Days remaining until demo becomes feature limited: 60
C:\Documents and Settings\Eric Haskins\Desktop\ifi_frc_beta\ifi_frc_beta\ifi_code .c:31:Error [1105] symbol 'ADC_VREFPLUS_VDD' has not been defined

Halting build on first failure as requested.

What did I forget?

EDIT: I moved it to a shallower directory, but it still returns that error.

EDIT: I uploaded a file with the output from the compiler.
