This is a quick setup guide to develop C++ desktop application with Gtkmm toolkit library using Geany IDE on Ubuntu. In other words, you can start learning how to create cross-platform GUI application. You know, Gtkmm is a C++ binding to the C-based GTK+ library, and this library has been used to create great desktop apps such as Inkscape and MySQL Workbench (also GParted and GNOME System Monitor!). This tutorial is a continuation to Quick Setup of C, C++, and Java on Ubuntu. This works on other Debian-based distros as well such as Mint, Trisquel, and elementary OS (however, I used this last one to write this tutorial). Follow instructions below and happy coding!
