Gcc Chroot Cross Compiler

[grahamr]

Hi guys,
As the pandora release is fast approaching :rolleyes: I am going to set up a chroot cross compile environment for pandoara with gcc (& g++), on x86_64.

Its been a year or two since i did this sort of thing (compiled gcc etc), if anyone uses a similar environment, i'd be grateful of any gotcha's or tips from anyone that might save me a bit of time before i start in. (by this i don't mean - "dont bother -just download from sourcery!")

crosstool-ng works well for something like this

Kewl! thanks pickle, I was just going to work from the individual tarballs. This looks perfect.

Out of curiosity, why isn't CodeSourcery an option?

You could use some of our Neuvoo tutorials. We use Gentoo with crossdev which is great for a small cross compiling env. If you plan on using vanilla code and since your compiling tarballs this will meet your needs quite well.

We have a complete image building guide, you can just follow the first 2 or 3 and build a very good cross compiling env.

I also have a quick install script that I made that set up the env and makes the appropriate edits/mounts.

The good thing is that you don't need to have a Gentoo host to use this. The build env just needs a linux distro with mount and chroot, there is no reason you can't do this under VirtualBox or VMWare also.

Thanks for this. I don't think i will build directly from the tutorials, but i will sift through them for any interesting bits.

btw - I used gentoo for years, I was fond of it, the quality of the documentation was good. (Now though i tend to use Arch for my desktop.)

Out of curiosity, why isn't CodeSourcery an option?

It is an option, just not the one i was asking about. Eventually i probably use both and compare results. At the moment I want a vanilla build that i can muck around with, for example I'm interested in comparing differences in assembler from GCC 4.4.3 and GCC 4.5.0.

pickle - THANKS AGAIN! i am in love with crosstools-ng. It make your life really easy, but transparently, so you can still patch/tweak where you want to.
In fact i've already done it and built one.
