Something tells me that someone has already done something like this. I can't remember the exact page I found but this may be helpful:

(Using -mfp=vfp is fine, as the OMAP supports that, and there have been no crashes reported from using the floating point unit. You may want to try -mfp=vfpv3 though, as we also apparently support that)

Side note - GCC 4.7.0 is available. Anyone up to try that?
I just removed the switch. I'll use the fremantle switch. Or are the 2 latter more efficient?

thumb2 may be the problem:

Try using these CFLAGS:
Code:
-mcpu=cortex-a8 -mfloat-abi=softfp -mfp=vfpv3 -marm
(Apparently, you can disable Thumb interworking from GCC. We gotta test this, as the N900 only bombs out with interworking enabled.)

Here's the same CFLAGS, with a potential Thumb fix:
Code:
-mcpu=cortex-a8 -mfloat-abi=softfp -mfp=vfpv3 -mthumb -mno-thumb-interwork

OK
Yesterday I compiled with these flags (before you posted)
Code:
-mfloat-abi=softfp -mfp=vfp
If this doesn't work I'll try out your flags.

It can be downloaded from http://marmistrz.net63.net/meecolay/libc6
Adf.ly link: http://adf.ly/9W8IF

I'll upload the rest if this works. If not, I'll recompile with other flags.

I didn't test it. If you have a R&D N900, you can try it out, but this is likely to brick it but there's a chance it works :)

EDIT: It works, but Calendar catches sigsegv on raise(). Calendar is the only app not working right now.
EDIT2: This libc6 seems to cause insane problems: all timezones are GMT +0 (due to not installed locales?), gray screen except the parts where something changes. I don't know how to fix it. Any ideas?

I tested these on just reflashed N900 (nokia kernel, no cssu).
Code:
wget http://marmistrz.net63.net/meecolay/libc6/libc-bin_2.10-0maemo18.1+0m6_armel.deb http://marmistrz.net63.net/meecolay/libc6/libc6_2.10-0maemo18.1+0m6_armel.deb
dpkg -i libc-bin_2.10-0maemo18.1+0m6_armel.deb  libc6_2.10-0maemo18.1+0m6_armel.deb
md5sums:

0f95c0d084149233179aa9cf2dd15f72  libc6_2.10-0maemo18.1+0m6_armel.deb

Phone boots correctly. What is the best way to know new libraries really are used?
Code:
/usr/bin/ldd --version
ldd (maemo eglibc 2.10-0maemo18.1+0m6) 2.10.1
Some applications work: e.g. Sketch, images, camera, calculator, browser, pdf-reader. notes.

Some applications are not working. e.g. Calendar keeps crashing (actually this is so far only not working application).

This moment I can only say:
Code:
/usr/bin/Calendar

  calInterfaceInitializeBackend(): Before Backend  initialize

[EDIT]
Installing CSSU-stable doesn't change anything. Calendar is still crashing on the loop.

With regards to the talk about gcc 4.7, does the new linaro toolset help/work?

Re: gcc-4.6 and Fremantle, WIP
 
If Calendar was the only app that's crashing after updating libc6 (I doubt this is the only one), this would be a great beginning for an OS Maemo-calendar rewrite project :) We already have alternative version of calendar widget, calendar-gui shouldn't be too hard (unless it uses some dbus signals or other internal system components - I have 0 knowledge about calendar app right now), the internals may be difficult (dbus hooks, deamons, etc - but again, I have no knowledge about this app right now)

OK, thanks. I'll be trying to work out the installation in /opt/meecolay. Probably will need to tuned the PATHs.
