Using QT in CentOS

[vishakvkurup]

Hi all,
This is my first post in this forum, and i am expecting all ur support.

I am having an application developed in qt 3.1.2 running in redhat 8. Now i plan to use CentOS 5, which is having qt 3.3.6 by default. Trolltech says qt 3.3.6 has forward and backward compatiblity with QT 3.3.x versions. So i need to recompile my code. I want to know if any code level modifications are needed for recompilation. If so what all are the changes. And is QT having any depedencies with the kernel. Pls do respond.

regards
VISHAK (vishak.kurup@nestgroup.net)

As the 3.3.6 changelog says:
It maintains both forward and backward
compatibility (source and binary) with Qt 3.3.5, 3.3.4, Qt 3.3.3,
Qt 3.3.2, Qt 3.3.1 and Qt 3.3.0.

Hi all,

Is it possible to use QT 3.1.2 version in CentOS 5. CentOS 5 is having QT 3.3.6 by default.

Yes, it should work fine. Qt has backward binary compatibility so an application compiled against Qt 3.1 should work with Qt 3.3 out of the box.

I don't run CentOS but if it uses a repository more than likely QT3.3.6 is in there and ready to apt-get, along with all necessary dependencies.

But, why are you staying with QT3.x? Upgrade to QT4.3.3 and leave the old stuff behind!
