PDAs, Cellphones, Wireless "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."

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.

Show me how I can build a binary application that will work on all Linux distributions made since 2005 up to 2007 without issue.

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.

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:

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.
