[gentoo-dev] ppc cross-compiler

[Philippe Coulonges]

Something puzzles me.

The gcc ebuild seems ready to handle installation of a cross-compiler,
but the binutils ebuild don't.

Is there a purpose ? 
Is it a work in progress ? 
Did I miss something ?

I'm unsure how tested that ability it.  I made some ebuilds for 
binutils/gcc sparc/mips64 support, and in doing so, inadvertently made 
them capable of building cross-compilers.  I'm also working on a script 
to do cross-compilers that I hope to put into portage maybe within 
another week or so....still beating the bugs out of it.

Well, my goal is to build a gcc X-compiler for powerpc-unknown-eabi
(embedded device).
I'm not hurry as it will be a replacement for a compilation chain that
works, so I would prefer a clean, gentoo's way solution.

I started modifying the binutils ebuild in the same way as gcc, i.e.
using env variable for the definition of the target and using SLOT. I
still have a headache on the install part to figure out where everything
should be.

Since you seem more advanced, I will wait for your work. I'm willing to
help however so you can pass me some scripts or ebuilds for testing if
you wish.

How things are planned to work (or was rather), you will only need one
ebuild, and the SLOT="${PV}-${CCHOST}" will ensure that you have
multiple SLOT's.  This support is however still not in portage, so
its a pita currently :/

Yes, we are waiting for multi-SLOT per version support
portage side.  Else I guess you could cp the binutils
ebuild to binutils-cross or something, and mod it a
bit, or use one of the few in bugzilla ...

Last month when I tried to emerge cross-binutils and cross-gcc and I
thought cross compilation support was already there ;/ I emerged
binutils for ppc first and for mipsel next, but SLOT'd binutils for
ppc was not protected when I installed binutils for mipsel (and thus
removed).
