You probably haven't installed the dependencies needed to build. In this case it's probably `libglib2.0-dev` which contains the GLib gettextize macros that appear to be missing, I believe.
Even easier though, just run `sudo apt-get build-dep geany` which should install all the packages and development files required to build Geany from source. -- You are receiving this because you are subscribed to this thread.
