Not a nice set of dependencies to satisfy, IMO.
My understanding from your original message is that you want to parse and
render SVG files. If this is the case then I highly recommend you look into
using Qt - http://qt.nokia.com/products ; which like Cairo and friends is LGPL
Don't let the fact that it is a full-blown widget toolkit put you off :) The
SVG module (QtSVG) is reasonably full-featured and extremely easy to use. In
addition the Qt source as downloaded has *no* external dependencies, compiles
under both MinGW and MSVC and can easily be statically compiled. Many build-
time configurations are provided. On my desktop I have full-blown statically
linked Qt applications than come in at under 1.5MiB. (And yes, they do make
use of the SVG functionality for icon rendering.)
It is worth pointing out that Qt is C++ based which may or may not pose a
This approach will significantly reduce the size of your application and reduce
the amount of manual dependency management you need to perform.
rsvg is great if you're writing a GTK+ based desktop application, but a
nightmare if you just want to add SVG functionality to a cross-platform
