Re: Is there any progress on the stl abi issues?
Le 04/07/2012 16:00, Matthias Klose a écrit : wrong. A workaround was applied on 2012-06-23, in 4.7.1-2ubuntu1. The complete reversal of the offending patch (with the same effect) is on the gcc-4.7 branch and will get into quantal with the next merge. Thanks for that, sorry for the wrong statement but we didn't notice the changelog entry for that, it would have been nice to follow up on the ubuntu-devel discussion to pointing it ;-) Please note that just using gcc-4.6 will help for this particular issue, but it's not about a 4.6/4.7 issue, but about mixing c++98 and c++11 code. The c++03/c++11 support in GCC has always been marked as experimental, and still is, so you may run into another incompatibility. There is a discussion going on what can be done about the compatibility, see http://gcc.gnu.org/ml/gcc/2012-07/msg00031.html, but for now just be aware that this compatibility is not granted. Right, is there anything in practice we can do to mitigate the potential issues (outside of porting back unity code to not use the new standard)? if this did work before, then this should be ok. But it's no guarantee that the there are other incompatibilities. The std::list issue is now reverted in 4.7 as well. Matthias Thanks!

There is work being done upstream in gcc-4.7 to try to fix the ABI for compatibility with gcc-4.6 (and with -std=c++99). In the meantime, yes, any packages that are being built with -std=c++0x or -std=c++11 should use gcc-4.6 instead. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

Not that it directly affects the packages that have been identified to have issues, but I did check with Qt/KDE upstream and they don't make use of the Standard Library, so it's not an issue for Qt/KDE.
