[gentoo-ppc-user] crosscompiling x86 and ppc

[David Bélanger]

Hi,

I would like to use distcc with cross-compilation.  Platform will be x86
and ppc.  Cross-compilation would work both ways.  Cross-compilation
setup should work with latest tools and kernels.  gcc 3.4, kernel 2.6.5.

I search google, Gentoo forums etc. and found various info but not too
many details.

I install the crossdev ebuild but I am having difficulty setting up
things.  I have currently built a half bootstrap gcc.  I had to do a
symlink to the include dir, the script or something else did not put
them at the right place (or gcc not looking at the right place.)  So,
currently, I'm stuck with the error message shown at end of message.

I am currently considering building the toolchain myself step by step.

Anyone has done this before that could provide some hint or stragegy or
reference to a HOWTO/Tutorial would be appreciated.

Thanks in advanced,
David
