I want to install kdevelop 4.5.2 on Ubuntu 12.04 I ran sudo apt-get install kdevelop 4.5 in the terminal and the installation had a few errors but things looked fine. if i run kdevelop i get the following error Could not find KTextEditor::Factory, check your installation: Make sure that Kate is installed, KDEDIRS is set properly and that you ran kbuildsycoca4. I tried to install kate but I got errors since ubuntu 12.04 does not support kdevelop 4.5.2 officially. Does that mean I'll have to build from source ?
