rcairo is a Ruby bindings for cairo(*).

Cairo is a 2D graphics library with support for multiple
output devices. Currently supported output targets include
the X Window System, win32, and image
buffers. Experimental backends include OpenGL (through
glitz), Quartz, XCB, PostScript and PDF file output.

makes a binary package for rcairo. This is included in the
following archive:

Hi,
I've installed cairo and rcairo on Ubuntu and none of the examples in
the samples directory works but png.rb.
Launching ps.rb gives me an empty file test.ps with the following error
:

ruby: symbol lookup error: ../packages/cairo/ext/cairo.so: undefined
symbol: cairo_ps_surface_create_for_stream"

If you can help thanks, I'm new to Ruby.

It seems that this is a cairo library search problem. It
seems that your rcairo was compiled with cairo which
supports PS/PDF but you use rcairo with cairo which does not
support PS/PDF.

Thanks a lot Kou, I'll investigate that way...maybe in the different
pathes.
