I installed cygwin on two computers... and then i followed the gcc cross compiler tutorial but at the end of make all-gcc i get error 2 and i'm really confused

Could you post more information about the error its self? Like maybe a screenshot or something like that.

EDIT: i saw at the end of the gcc compile that there was a message along the lines of "line: 7889 cmp command not found"

i'm trying to build gcc version 4.2.1

Having just cross compiled gcc 4.2.1 to target i586-elf from cygwin, I can assure you that the commands given in the wiki page do work. I used the recently released binutils 2.18.

In particular, have you 1) cross-compiled binutils? and 2) run the all important 'export PATH=$PATH:$PREFIX/bin' step after compiling (and installing) binutils.

If you follow all the instructions provided in the wiki page exactly you shouldn't have any problems. I.e. don't try compiling within the gcc source directory or anything like that.

i got it setup but i have a slight warning:

As you're getting warnings from compiling main.c, and you're treating them as errors, main.c doesn't get compiled to main.o. Therefore its not unreasonable that ld can't find main.o.

John.

i know why i get the linking error but i want to solve the warnings

main is always defined as:
You fail on three aspects of this definition. If you want to make a different interface, call it differently.
