To build pidgin on Ubuntu linux you’re going to need a whole bunch of libs and tools. Let’s check you’ve got the base dev tools installed:
sudo apt-get install build-essential
Next the glib stuff and libxml:
sudo apt-get install libgtk2.0-dev
sudo apt-get install libxml2-dev
I’m not sure if you need this separately, however libpurple is the plugin system for Pidgin:
sudo apt-get install libpurple-dev
Finally mop up any specific pidgin dependencies that are missing:
sudo apt-get build-dep pidgin
If you haven’t already downloaded the Pidgin source get it here:
http://www.pidgin.im/download/source/
Uncompress it:
tar zxvf pidgin-sipe-1.11.2.tar.gz # change for your version
cd into the directory, then run:
./configure
make
make install
Enjoy!
