Getting started with ATK

To configure ATK, run the ./configure script, then ‘make’ and ‘make install’. If you are installing into a location where you don’t have write permissions, you’ll have to become root before running ‘make install’.

General information about building ATK and related libraries can be found at To compile a CVS version of atk on your system, you will need to take several steps to setup the tree for compilation.

You can do all these steps at once by running the “cvsroot/atk# ./” command, without quotes. Basically this does the following for you ‘cvsroot/atk# aclocal; automake; autoconf’. The aforementioned commands create the ‘configure’ script, which can be run in cvsroot/atk to create all the Makefiles.

Before running or configure, make sure you have libtool in your path. Note that runs configure for you. If you wish to pass options like –prefix=/usr to configure you can give those options to and they will be passed on to configure.
