[Buildroot] native toolchain compilation problem

[William Brodie-Tyrrell]

Hi,

I'm using buildroot to build a linux system for the AT91SAM9G20-EK board and it's working fine except that I can't get it to build the native toolchain.  The cross-compiler works perfectly.

I'm using a patched v23434 from SVN as instructed by this website:
http://www.linux4sam.org/twiki/bin/view/Linux4SAM/BuildRootBuild

The error I'm getting is this:

Looks to me like the gcc build process somehow doesn't see the built uclibc (no fprintf, no stderr) - is there something I need to change to fix that?


thanks,
