[geos-devel] perl bindings for geos (Geo::Geos)

[Ivan Baidakou]

Hello, 

We (i.e. crazy-panda.ru) are glad to announce perl bindings for geos [1]. The bindings are done 
for C++ geos interface, and mostly maches 1 to 1, when it is possible to keep API "perlish",
i.e. not to crash due to dangling reference.

The bindings where successfully tested for Linux and FreeBSD. At the moment for Windows bindings
are not available.


PS. There were a few compilation issues on NetBSD, reported by cpantesters (i.e. [2]). I wasn't 
able to figure out what's wrong here:

     ^

however, disabling the following line

check_include_files(ieeefp.h HAVE_IEEEFP_H)

in CMakeLists.txt fixed the situation with compilation on NetBSD [3].
