QT4 development with QDevelop
- Install QT4 development packages and cmake. Not all of them are needed, but these are nice to have:
apt-get install libqt4-core libqt4-debug libqt4-gui libqt4-qt3support \ libqt4-sql qt4-designer qt4-dev-tools qt4-doc qt4-qtconfig exuberant-ctags cmake
- Download QDevelop source from http://www.qdevelop.org/
- Untar the package, cd to its directory, then run:
cmake . && make
If everything works as it should this should produce a binary file in bin sub-directory, you can run it with ./qdevelop or if you want you can move it to /usr/bin and then run it by typing "qdevelop" in Run Command.
- Run update-alternatives as root and change the relevant links from qt3 to qt4.
