[Solved] Linux 64 bit Qt segmentation fault

img_man

Hello,

I'm having some trouble using Qt 5.1.0 or 5.1.1. The installers work fine, and I can use the installed version of qmake to create makefiles for the examples and build them. When I try to run any of the examples, they fail with a segmentation fault.

I am able to install Qt 4.8.5 (using ./configure and make) and run it's examples without issue. Is there a known issue here?

Hi,

Where does the segmentation fault happen ?

Here's the gdb trace.

Can you build Qt 5 and try the example again ?

img_man

Yep, in the process. Will post again soon with results.

The self-built version of Qt-5.1.0 appears to work correctly. I suggest somebody fix those installers...

The you need to report the problem on the interest mailing list, you'll find Qt's developer/maintainers there (this forum is more user oriented)
