I will quote my post from Meecolay development thread, as marmistrz said it may be useful to you:

The site I'm talking about is http://linuxtesting.org/compatibilit...at_report.html . The report with problems for libc.so.6 is accessible here: http://linuxtesting.org/compatibilit..._Risk_Problems (if you click at "+" signs near functions, you will see the exact explanations of differences). This may explain why new libc crashes some apps

This just runs flash.py with standard images:

At this point you need to obtain the following files:

* moz-n900-vNN.ubi - mozilla custom firmware
* RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin
* RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin

Except for OSX specific moz... it still flashes standard bins, or maybe I missed something. Still would be nice to create flashable images for exchange (full images, here try thumb2 CSSU with KP51testing and full SDK chroot, wait, use this Ubuntu12 with full -dev libs... hope this is not a dream)

UbuntuArm 12.10 (Alpha) which uses GCC 4.7.x is faster then UbuntuArm 12.04 which uses GCC 4.6.x

http://www.phoronix.com/scan.php?pag...210_arm1&num=1

Not all performance increments are due only to newer GCC version, but surely the newer GCC plays a big role

Side note - GCC 4.7.1 with 100+ bug fixes is available

I compiled newer libdsme0.2.0, for compatibility with meego.
Can anyone test it?

If there are any problems, you can try commenting out maemo-optify from debian/rules and recompiling it.

It's here: http://marmistrz.net63.net/public/dsme/

Wow, finally caught up on this thread after my mostly-absense from TMO, and I am fascinated by how much progress has been made so far.

You know, on the one hand, I am disappointed with my failure to get involved in this, on the other hand, it seems like the entire endeavor of getting newer gcc, libc, etc, onto the N900 let alone getting to the point of succesfully replacing the older ones completely, is way out of my league.

I just want you all working on this to know I appreciate your work on this matter. If any of you take donations let me know, and in the meantime if/when I can, I will attempt to jump into this and contribute.

First testing of gcc-4.7.1. I don't have debs yet. I have only tested: 'gcc --version'.

Run on scratchbox1:
Code:
wget http://ftp.de.debian.org/debian/pool/main/g/gcc-4.7/gcc-4.7_4.7.1-1.diff.gz
wget http://ftp.de.debian.org/debian/pool/main/g/gcc-4.7/gcc-4.7_4.7.1.orig.tar.gz

gunzip gcc-4.7_4.7.1-1.diff.gz
tar xvf gcc-4.7_4.7.1.orig.tar.gz

mv gcc-4.7-4.7.1.orig gcc-4.7-4.7.1
patch -p 0 < gcc-4.7_4.7.1-1.diff
cd gcc-4.7-4.7.1/

For donation link, look at my signature.
There'll be some more dsme packages, now I'm waiting whether the maintainer of libbme from gitorious adds debian/*
I'm uploading newer libiphb, the same link as here: http://talk.maemo.org/showpost.php?p...&postcount=114

I've built scratchbox toolchains for the Maemo5 SDK based on Linaro 4.6/7-2012.06, they're available here:

http://www.snewbury.org.uk//maemo/li...armv7a.tar.bz2
and
http://www.snewbury.org.uk//maemo/li...armv7a.tar.bz2

Just unpack into "/scratchbox/compilers", and they'll appear in the list when setting up a target.

I'm trying to compile glib 2.28 from Harmattan, but the autotools are detected as too old, even though I installed automake1.10-autoconf264 and autoconf2.64.
What am I doing wrong?
