Hi,
Using GCC you should add the following to the command line:
`pkg-config --cflags --libs libsvg-cairo`
This includes and links the necessary libraries.

If you create the cairo_image_surface after parsing the SVG and after calling
svg_cairo_get_size() you can use this information to create a surface which has
exactly the same size as the SVG.

Kind regards
Ulrich
