Description Martin Walch 2013-02-18 19:19:36 UTC 
Compiling fails with gcc 4.4.7. I am not sure if this comes from text-ui or from QtGStreamer:

Reproducible: Always




gcc (Gentoo 4.4.7 p1.1, pie-0.4.5) 4.4.7
Comment 1 Martin Klapetek 2013-02-19 08:47:00 UTC 
Do you have telepathy-logger-qt-0.5.3 installed?
Comment 2 Martin Walch 2013-02-19 10:25:01 UTC 
Yes, I have tried several versions of ktp-text-ui and telepathy-logger-qt, including 0.5.3 of both. Line numbers in the error message may vary slightly, but the error is always the same.

I should have mentioned in the first place: it works all fine with gcc 4.6.3.
Comment 3 George Kiagiadakis 2013-02-19 10:35:25 UTC 
This shouldn't be happening, tbh, but you shouldn't be using such an old compiler either, as QtGLib will fail at runtime -> http://cgit.freedesktop.org/gstreamer/qt-gstreamer/tree/README#n43
Comment 4 Martin Walch 2013-02-19 11:01:25 UTC 
Thank you for the link. Is it sure that QtGLib is likely to fail at runtime when using gcc 4.4? Shouldn't cmake then fail when encountering <=gcc-4.5?
Comment 5 George Kiagiadakis 2013-02-19 11:13:05 UTC 
Yes, it is sure that it will fail if you use the libstdc++ provided by gcc 4.4. I haven't done any strict cmake checks because it is only a runtime requirement. You should be able to compile with gcc 4.4 and run the executable with libstdc++ 4.6 just fine.
Comment 6 David Edmundson 2013-03-11 13:16:16 UTC 
George's answer seems valid, closing.
