Double Commander

Hi!

I compile doublecmd-qt (32 bit) with branches/0.5 r3923 in linux.
I use:
./build.sh all qt
The compile is fine.

When I start doublecmd-qt, it crash.

Here is my doublecmd.err:
--------------- 26-09-2011, 21.19.14 ---------------
| DC v0.5.0 beta Rev. 3935M -- i386-Linux-qt4
|  -- QT 4.7.4, libQt4Pas 4.5.3
Unhandled exception: EAccessViolation: Access violation
Stack trace:
$B53D15CE

The problem is the doublecmd.xml file. If I start the doublecmd-gtk2, it is work fine, it can write the doublecmd.xml. After when I start the doublecmd-qt again, it is working, use the doublecmd-gtk2's doublecmd.xml file.

The doublecmd.xml has 644 permissions.

Is this problem just mine?

So it crashes when you don't have doublecmd.xml file? For me it works fine.

Try build with with debugging info and reproduce the crash.

Hi!

The first start the dc-qt copy the doublecmd.xml file in $HOME/.config/doublecmd/ too.
But it is the default doublecmd.xml file, I think the dc-qt can't write it. The dc-gtk2 can write it. If dc-gtk2 modify the doublecmd.xml, the dc-qt can use it, and start. Maybe.

I recompile dc with:
lcl=qt ./build.sh nightly

In start this crash too.

The reading/writing of doublecmd.xml does not depend on QT or GTK2, it must be something else.


Yes, but I thought there will be a better stack trace.

I tried with i386-Linux-qt4 with the default config and it does not crash.

Tomorrow I will make a build with full debugging info and give you to reproduce the crash again.

Please download this DC version and try to reproduce the crash:
dc-0.5-i386-linux-qt-dbg.tar.bz2

Crash again.

Why does crash the qt version, if gtk2 version not?

It should have shown where it crashes. Maybe the crash is in some system library, like QT lib or something that is why it doesn't show.

If you run from console, what is the output?
