I recently upgraded my cairo bindings to 1.8, and my ruby-gnome2  
bindings to  
0.18.1.

Everything seems to be working nicely (less leaks!), with one exception:  
after loading the rsvg2 bindings, my cairo contexts don’t have the  
render\_rsvg\_handle method added to them.

I’ve traced this issue to the check\_cairo refactor in revison 3294.

The temporary solution I used as a workaround was to add the following  
line to rsvg/extconf.rb

have\_header(“librsvg/rsvg-cairo.h”)

It appears that line doesn’t get called in the new check\_cairo function,  
so the Makefile generated for the rsvg bindings doesn’t add  
-DHAVE\_LIBRSVG\_RSVG\_CAIRO\_H to CPP\_FLAGS.

You’re right. The check is missing. I’ve fixed it in trunk.  
Thanks for reporting!
