In order to compile a software (https://github.com/bnordli/rftg/wiki/Compiling-on-Linux) I first need to install the gtk+2.0 package. But I cannot find it with aptitude search.
Any idea?
To install gtk+2.0 package you should run:
apt-get install gtk2.0
The development files for the GTK+ library can be installed through :
apt-get install libgtk2.0-dev
configure step mentioned explicitly a gtk+2.0 package. I should have thought better and search for a gtk2 dev-lib. Sorry, I was tired. Thanks for this obvious answer!
