[geos-devel] Can't build geos with ruby swig bindings on Mac OS

[Ramie Blatt]

I'm wondering if there's *anyone* out there who has successfully  
built GEOS 3 with swig and ruby on Mac OS?

I've spent a lot of time on this and keep coming up empty...

I tried building GEOS with ruby enabled using the hourly svn snapshot  
yesterday and get the same "make" issue I get with the  
geos-3.0.0rc1,2 and 3 tarballs, namely:
"geos_wrap.cxx:1702: error: invalid conversion from 'size_t*' to  
'unsigned int*"

Strangely, the geos-3.0.0rc4.tar.bz2 release builds fine, but then I  
can't access GEOS in ruby, getting a "MissingSourceFile: no such file  
to load -- geos" whenever 'require 'geos' is encountered (though the  
library files seem to be where they should).

Again, any help on this is great;y appreciated!

Best,
Ramie
