How to manage multiple distributions, cross compilers in one chroot environment
 

Hi,
Continueing the discussion started by my last thread "CBUILD= HOSTCC=-gcc",
I said I want to compile a cross compiler with a special name.
I wanted i686-gentoo.edge-linux-gnu but it is possible to do just i686-pc-linux-gnu



I did this because crossdev creates some magic setting up things, and it is very handy.
What I want is a way to keep few compilers environments.
lets say:
stable x86 compiler
unstable x86 compiler
few arm cross compilers.



So when I create a distribution and an few month time I want the same exactly environment,
to compile and upgrade few packages and be sure not to break anything, I want to keep
those version of the compilers.



I'll also need some way to have few forks of my initial system.
lets say:
emebedded board 1 - for customer A
emebedded board 1 - for customer B (it is different than A, by time of creation and so by version of the compiler used).


emebedded board 2 - for customer C

Can we boost up crossdev, or I need to start hacking a distro_creator utility for gentoo?

Regards,
Kfir

No boosting neccessary. Just use crossdev with some explicit version

numbers for all components, and you get excellent repeatability.


Ok, lets say I create a special crossdev. I still get it in /usr/i686-pc-linux-gnu,
which is very generic.
Can't I have few compilers at a time?






As for distro creater, I use catalyst to build a stage4 and stage5.

Not sure how well that works for cross platform however, I only use

on amd64 to build for various x86, and this may be a special case.


I'll take a look on catalyst.
Can you refer me to a good introduction/manual ?
The gentoo page is not enough for me.

Even it might get off scope of this Gentoo specific list:
you can easily do this with crosstool-ng and Briegel.
