Could it be possible to, at least, upgrade the OBS and Scratchbox to gcc4.4?

That would be a point to start with. Rebuild CSSU, then start rebuildong some application in extras-devel, finally every new application pushed to extras could then be built with a newer version of the compiler.

Here is how to add the harmattan repository. Libstdc++6 v4.4 is out there.

I'm downloading Aapo's stuff, and will check it out.

EDIT: has anyone tried installing this directly on device?

Has anyone tried to compile libc6 >= 2.10?
I managed to run lots of harmattan apps using meego binaries + Aapo's libstdc++6, but now newer libc6 is missing. Binary ver. from meego not working

I'm on it, namely on trunk of elibc (version > 2.15). I'm not fully tested results or checked steps, but here comes sketch how it should go (my vision).

(I have binutils2.22 installed, not sure is it needed. More info later)

You need newer gcc than 4.2.


Libc needs autoconf2.68.

Autoconf2.68 needs:
m4 1.4.13, but we have only 1.4.8-2.
pkg-config 0.26, but we have only 0.22

Re: gcc-4.6 and Fremantle, WIP
 
@marmistrz Four weeks ago you advised me how to get binutils2.22 to the repository, now I'm trying to achieve it (some issues with autobuilder).

Package name is binutils2.22 (no conflicts with existing package names). It's files goes to the /usr/binutils2.22/bin, /usr/binutils2.22/lib and ... (no conflicts with existing files). And name of binaries is still as expected, e.g. ld.

And it is used:
Code:
PATH=/usr/binutils2.22/bin:$PATH
LD_LIBRARY_PATH=/usr/binutils2.22/lib:$LD_LIBRARY_PATH

I could test whether it works with forum-tmo from meego.

When put to /opt/meecolay/lib, named libc.so.6 (and set LD_LIBRARY_PATH to this)
this gives Segmentation fault.

Even running meecolay, which is just a modified /usr/bin/preenv script. (diff. vars & preloads) there is Segmentation fault

The same happens with MeeGo's libc6 (2.10 or 2.9 iirc)

is newer libstdc++ > 4.6 required or some other lib?

With harmattan target I fetch apt-get source libc6 and compiled it for fremantle target.

Strange, these are still old 2.5 packages, as in fremantle.
I was talking about these packages.
Was it a typo or did you build eglibc v2.5?

note: if you want exact details about the harmattan repo, they're right there: http://forum.meego.com/showpost.php?p=27649&postcount=2

You are right, I messed with my targets. Yes, last one was fremantle packages for fremantle (not very excited).

Re: gcc-4.6 and Fremantle, WIP
 
Package binutils2.22 are in extras-devel. It doesn't conflict with any package (no names, no files).
Code:
/usr/binutils2.22/bin/ld is symlink to the ld.bfd
and
Code:
ldd /usr/binutils2.22/bin/ld.bfd
->  /usr/binutils2.22/lib/libbfd-2.22-system.so
So LD_LIBRARY_PATH might be useless.

At least this is working:
Code:
PATH=/usr/binutils2.22/bin:$PATH ld --version
-> 2.22

Compiling Harmattan's libc6 keeps qemu crashing. I decided to compile it straight on the phone. It could take days, 10 hours back already. (And I'm not still sure will it compile, and will result work as expected)

Seems hard.
I'll fire up my maemo sdk, just to check whether it's a sb2-connected problem

N' I've got an idea, why the libc > 2.11 doesn't work. Harmattan's is eglibc. The ubuntu's/debian's/whatever's is normal glibc.

OK, I copied the libc stuff to /opt/meecolay/* and still segmentation fault.
Seems that it's not as easy to tame as libstdc++6.

Do you have any idea why it causes seg fault?

I'm not @ home, so I'll upload only libc6 and libc-bin.
I'll upload the rest later.

Re: gcc-4.6 and Fremantle, WIP
 
I'm proceeding with gcc-4.6!

I dropped i386 version entirely
(
It tries to compile i386-version with 64bit multilib support, and that is very hard to turn off. It was easier to me to just drop i386 version. Do we need this?
)

Now extras-devel has gcc-4.6 package which contains working binary for gcc-4.6. It still has some dependencies for non-existing packages, so it can't be installed (but can be downloaded and extracted).
http://maemo.org/packages/package_in.../4.6.1-maemo5/
Next version is on builder already, but it takes some 48h to compile.

Packaging of gcc is tricky as it generates/modifies own packaging files during packeting.

On developing/hacking device, yes. Maybe not on everyday device.

I upgraded my device and it is still booting (without RD-mode) and working. I have tested only couple of applications, but they worked as earlier.

So I'll wait until it's more sure that it's safe, as N900 is my main device

Btw. I uploaded the source I built. The depends have to be modified, as I used -d flag

It's the md5sum, as I had problems uploading

Heh... I was wondering where did the 4.6 come from in apt-get. Sadly fighting to get a working automake/conf I forced a thing or two too many and my testing device no longer boots. Will test the libc6 as soon as I get it flashed (laptop also crashed, so unless I can flash with the second N900, might take a while... this has been a bad week for tech)

This would be perfect as a 'vanilla' if you will N900 is a perfect test candidate (maybe kernel-power would be a good idea due to the vast amount of linux-features it provides).

[OT]
I have to say the idea of flashing an N900 with another N900 is pretty cool. So long as you have hostmode and a compiled version of flasher-3.5 it should be perfectly doable :)
