"A few months ago, the GNOME Mobile Platform was announced to the public. One of the main forces behind the launch of this initiative was Nokia, which uses a lot of GNOME-components in its Linux-based Internet Tablets Nokia 770 and N800. During this years GUADEC Andreas Proschofsky had the chance to sit down with Carlos Guerreiro, Nokias Manager for Open Source Software, to talk - amidst other things - about the not so different needs of personal computers and mobile devices, about the necessity for GTK+ 3.0 and the impact of the iPhone launch."

The problem with the C++ Linux ABI (which is really the GNU C++ ABI) is that it changes frequently.
I am no developer, but I do run gentoo, and I know when the c++ abi changes due to a gcc upgrade (I have to rebuild everying linking against libstdc++), and if I remember correctly, there hasn't been an abi breakage since the upgrade from gcc-3.3 to 3.4, and 3.4 was shipped in April of 2004. So, comparitively with the previous abi history of gcc (about 1 break per year), things have stablized considerably in C++ abi land with gcc 3.4+.

Wrong, the ABI recently chnaged again in 4.1:

Show me how I can build a binary application that will work on all Linux distributions made since 2005 up to 2007 without issue.
Well apparently every proprietary software developer using Qt on linux has figured it out. As someone else already pointed out, there hasn't been a breakage for a long time (~2004), so just building it normally should accomplish what you want.

Wrong again.
See the recent GCC 4.1 release:
http://gcc.gnu.org/gcc-4.1/changes.html
Also, note that I specifically stated that I wanted to build an application that worked on distributions made since 2005. There have been at least three ABI changes since 2005.

Dude, welcome to 2007. No, scratch that, welcome to 2002. There is no "horrid ABI situation" with C++ on Linux.
Bzzzt. Wrong.
Show me where the C++ ABI standard is for Linux.
Show me where there is a gurantee that it won't change with the next version of libstdc++, or for at least the next few years.

Oh wait, you can't.
That's my point.
The problem with the C++ Linux ABI (which is really the GNU C++ ABI) is that it changes frequently.
This means every year I hear that the "C++ ABI problems are solved!" and every year I encounter problems that were supposedly solved last time.
