Hi,

OpenEmbedded-Core/meta-linaro:

• added a default xorg.conf for the qemuarmv7a MACHINE
• necessary because OE-Core master switched from Xfbdev to Xorg
• noticed that hard float with Linaro GCC 4.6 works on denzil but is broken

on master due to differences on the requested/provided interpreter

• it used to (accidentally?) work when /lib/ld-linux.so.3 was used even

for armhf

• need to check out what loader name OE-Core really wants to use

OE-Core shouldn't care, but the GCC and GLIBC do have to match. The GLIBC patch is in trunk, should be in the upcoming 2.16, and I'm looking into a backport for 2.15.(2?).

The current master branch of OE-Core happens to have the libc patched already [1]. I therefore backported r114985 of Linaro GCC 4.7 to 4.6 [2] and everything works as expected. We now have single a base that allows us to build all three images on all supported QEMU targets with the latest versions of Linaro GCC 4.6 and 4.7. The corresponding versions are: * openembedded-core 363424c * bitbake: f8bf449 * meta-linaro: b4f5e10

There's only one patch I put on top of this [3] to disable the -fno-tree-vectorice flag they turn on by default for armv7a.

...

• worked on getting OE-Core to build with Linaro GCC 4.7
• verified that the recipes for Linaro GCC 4.7 are working for ARM, MIPS,

PPC, X86, X86_64

• all images are working!

Awesome.
