QxOrm on Linux with gcc 4.6.1, Qt 4.7.4 (Ubuntu 11.10)

[pyrrhula]

Hi there,

I've tried to compile an in-house application using QxOrm on a computer that was recently upgraded to Ubuntu 11.10. It works fine in the previous 11.04-distribution that has an older version of gcc. What happens now is that the application crashes quite immediately. I'll paste an example crash backtrace below.

The gcc version is now at 4.6.1, Qt is 4.7.4.

- Is this a know problem with QxOrm?
- If yes, are there plans to fix this? (I'm aware that the website says tested on GCC 4.4.1).
- Or are there some other tricks that may be done to avoid this crash?

Let me know if I can help with further tests etc.

Best regards

Hi,

I have never tested QxOrm with GCC 4.6.1 but I think there is no problem.
Maybe you can try to recompile boost libraries and Qt libraries with GCC 4.6.1 => you have maybe some old binaries compatible only with an older version of GCC ?

PS : have you tried to execute all samples projects of './test/' directory ?
You can compile all of them using './tools/gcc_build_all_debug.sh' script...

Hi,

thank you very much for the quick response!

Following your tip I have now tested the test applications and they work without problems.

It turns out, the crashing application was accidentally linking to a static library version of QxOrm (with fresh builds of the static QxOrm lib, not some old one). By using dynamic linking instead it works. I haven't tried to build the QxOrm test apps with static linking to see how that goes, we're aiming for dynamic linking anyway because of the LGPL license.

Thanks again
