While porting Qt project from windows to linux(ubuntu) i faced with the following issue:
on windows Qt version 4.8.1 is installed
on linux 4.6.3 in which some functionalities availiable in higer version 4.8.1 don`t yet implemented (ex. QUdpSocket::joinMultiCastGroup).
I see only one solution to this problem: upgrade Qt version on linux to 4.8.1.
How can I do this?
On linux I got installed libqt4-dev, qmake.
Solved: I changed repository from squeeze (stable) to wheezy(testing), in wheezy latest Qt version is 4.8.1, which is perfectly suits my needs.
Using package manager I found package libqt4-dev and selected it for update.
That is all, the whole process took 5 minutes.
Disadvantages:
– As I run Debian on Virtual Box after changing repository I had to reinstall guest additions
– wheezy is less stable than squeeze (I haven`t faced yet with stablilty problem)
