We put occasional tarballs of development snapshots in the development download area.

We have the sources for libvips and nip2 on github.

To check out a copy of the source:

git clone git://github.com/jcupitt/libvips.git

You'll need to rebuild the configure system after downloading:

cd libvips ./bootstrap.sh

Then you can configure ; make ; make install as usual.

./configure  make make install

If you want to make changes and merge them, make an account on github, fork vips, edit as you please, and push commits upstream as you make them. gitref.org is a very handy getting-started guide to git.

There are separate HOWTO guides to help you Build on windows and Build on OS X.
