Dependencies
Be sure to check the prerequisites before building.
Note that most prerequisites are optional, meaning Navit will build without them, but you may find that you have some crucial features missing such as the GUI.
Prerequisites are operating-system dependent:
In general you will need one of ksvgtopng, rsvg-convert or
Inkscape to build pre-scaled icons in the xpm directory - the build
process will detect if you have one of those installed, and warn you
otherwise.
Please see platform specific sections such as Nokia N8x0 for their additional development environment dependencies.
