Linaro cross toolchain backport PPA [1] got updated to recent Ubuntu 12.04 versions:
- gcc 4.5.3 - gcc 4.6.2 - binutils 2.22 - eglibc 2.15 - linux 3.2
I tested both compiler versions against few packages, U-Boot and Linux 2.6.32.
Those packages may also work under Ubuntu 10.10 'maverick' and 11.04 'natty' but it was not tested. Users of Ubuntu 11.10 'oneiric' may install libmpfr1ldbl package [2] and then use 'lucid' repository to install cross compiler while I will prepare packages for their version of Ubuntu.
Please report any problems with those backported packages in launchpad [3][4][5].
