[gentoo-embedded] cross compilation kernel makefile variable

[John Utz]

Hello;

Can anybody tell me what variable i need to set in the kernel makefile
or elsewhere that points the build to my cross compile gcc?

i have tried setting, CC, HOSTCC and a few other things and it hasnt
worked.

no matter what i try, the build seems to keep using the system gcc and
that is mighty annoying. 

the only way i have managed to cross build a kernel is to actually mv
the system gcc out of the way and make a softlink to my cross-compiler.

which works, but causes a large chunk of grief when i try and build an
app for my desktop and then get the wrong executable format for my
desktop because i have forgotten to return the gcc link back to
pointing at the system gcc. :-(

what am i failing to understand about the kernel build process?

tnx!

johnu
