Howto Cross Compile GCC to run on PPC Platform

Howto Cross Compile GCC to run on PPC Platform

[Jeff Stevens]

   I am trying to compile GCC on an x86 platform to
run natively on an embedded PPC platform.  I am able
to compile gcc as a cross compiler (to run on x86),
but can't seem to get it to cross compile gcc (to run
on ppc).  Does anyone know of a good HowTo to do this?
 I'm currently downloading the source distro of ELDK,
so if it's already in there I'll find it, but if there
is one elsewhere online please let me know.

Thanks,
   Jeff Stevens

Very good, full of features.

I've used crosstool-0.38 to generate an ARMv5b cross compiler and  
then the script referenced from the link below to create the native  
GCC from the cross compiler.  It should really be not much different  
to make a PPC native platform.  I hope you have a fast machine.. It  
takes a while.

My favorite cross tool chain site:

Building and Testing gcc/glibc cross toolchains
http://kegel.com/crosstool/

Look into Canadian crosses.  At the very least you should find the
discussion helpful.

the Linux From Scratch site also has some useful discussion on
building toolchains:

I'd use the ELDK if I were you as an x86 hosted cross compiler, if only 
because it makes sense in terms of compiling bootloader & kernel with 
the same toolchain. Also, if memory serves the ELDK comes with a powerpc 
gcc in the supplied ppc root file system.

Alternatively : you can use the uClibc toolchain, to generate a similar 
setup.

Here's a script I've thrown together since I sometimes need to generate 
gcc toolchains easily for various targets. I've tested it with arm and 
powerpc and because, it might be useful to switch between c libraries. ymmv.
http://netsoc.dit.ie/~deckard/software/build_compiler.sh. This script is 
based on some excellent documents that Red Hat produced.

It is.

Note that released versions of the ELDK (up  to  and  including  ELDK
3.1.1)  require  a  RedHat-7.3  build  host. Don't waste your time on
trying later Linux distros ;-)

Current top-of-tree in CVS should build under Fedora Core 4; but this
code has not been released yet - it is beta quality only.

Best regards,
