Yes, I've had it working on XP SP2 32-bits (if that was your question)
check the following:
Did your path environment change 'take' ?
- in a cmd box,
change to the path that contains your source 'Makefile' - type set <Enter>
- check the PATH
- if Ok, try 'gmake fir' again; if not you might have to reboot first.
Other possible 'spoil-sports': any compilers that use the make system and have their path
before your 'gcc\bin' in PATH
You could also try my Windows shell for trunk building here:
