So I tried changing Render () to Render CInt in four places in SVG.chs.
Aye, the cairo C library changed it's API from 1.6 to 1.8. It added an int return type to several functions that previously returned void.
Now it installs OK with 6.8.3, and all the demos run.
I'd have a go at getting it to work with 6.10.1 if I knew what to do. It appears the library structure has changed incompatibly (and ghc didn't even change its version number - that's pretty bad).
The version of ghc did change of course, 6.8 -> 6.10, but perhaps you mean the versions of the libraries? They changed also, to reflect the API changes.
Is there a document anywhere that details the structure changes?
Yes, the ghc-6.10 release notes. Duncan
