**Premise** Befor you do anything, please make sure, that you have the following packages installed: - libglib2.0-dev - intltool - gnome-common The name of the package may vary from distribution to distributon. The first two packages provide m4-files needed for the generation of the configure script. The files in need are: - intltool.m4 - gsettings.m4 They should be located somewhere in /usr/share/aclocal. **Installaton** If everything is in place, run ./autogen.sh to generate the configure script. If everything worked well, do: ./configure --prefix=/usr && make To install the extension to your home directory, run make local-install Or to install it for all users you need administrator rights. Thus you've to use something like sudo or become root via su. Using sudo, simply run: sudo make install Restart gnome-shell after that (using Alt+F2, enter "r" -- without quotes). If you wish to translate TeaTime to your language, have a look at the directory "po". A handy zip file can be created using: make zip -- This is the same you get via http://extensions.gnome.org Thanks to Thomas Liebetraut for the new build system.
