HOW DO I COMPLIED LINUX KERNEL?

I'm trying to compile the new 2.6.17.7 kernel.  I compiled it successfully (well, almost successfully - worked but the VGA was screwed up - didn't care because all i do is ssh in the box anyway) once, but then when i tried again for a different system, it stops and gives me this crap:

make: *** [.tmp_vmlinux1] Error 1

WTF is i2c and why do I need it.  I tried recompiling with I2C support enabled in Device Drivers but I still get this crap.

Any ideas?
