Segmentation fault when installing QtIFW on Linux

[Mimi76]

Hello to everyone,

I am currently trying to install Qt Installer Framework on a Linux virtual machine (Debian 8.2 amd64).
However, whenever I try to execute Qt Installer Framework setup (V2.0.1) I get a segmentation fault.
For information, I try to install only the 32bit version of Qt Installer Framework, in order to create 32bit setups only.

Of course, my virtual machine has the i386 libraries installed and 32bit application can run (mine works fine even compiled in 32bit).
All libraries required by the Qt Installer Framework setup are installed (I saw it with ldd)

I made some tests : it seems I can run 64bit versions of the setup correctly (QtIFW and QtCreator (itself made with QtITW)).
The 32bit versions of these setups do not work however : always return with segmentation fault.

To get details on the crash, I execute the command "./qt-installer-framework-opensource-2.0.1-x86.run -v" and get the following output:

IFW Version: "2.0.1"

Erreur de segmentation

For information too; on another linux machine (Linux Mint amd64) the 32bit setups works perfectly.
So I suppose the problem comes from Debian where less libraries are installed by default.

So, has anyone of you an idea on my problem ?

Thank you and sorry for my bad English,

I found !

For those interested; since dmesg did not gave me any answer, I lauched my setup with gdb:

gdb-multiarch qt-installer-framework-opensource-2.0.1-x86.run

Seeing it was comming from QDBus, I looked for libdbus* on my machine debian and my machine mint.
Only mint add the /lib/i386-linux-gnu/libdbus-1.so.3 file.

So I installed the DBus library:

sudo apt-get install libdbus-1-3:i386

And now it works!

Bye Mimi76

PS: Sorry I do not know how to close/mark as solved the topic.
