[geos-devel] C API busted for Windows

Tue Nov 14 11:20:16 EST 2006

This solution is not so pleasant for the svn developer types (go to a 
gnu system and autogen.sh/configure and copy the file or hand tweak 
and copy the file), but we can cope I suppose.

The C API is still pretty busted on Windows though.

- Both the .cpp and .h files are doing extern "C", which MSVC doesn't like:

>..\capi\geos_c.cpp(124) : error C2733: second C linkage of 
>overloaded function '
>GEOSDisjoint' not allowed
>         ..\capi\geos_c.cpp(123) : see declaration of 'GEOSDisjoint'
>..\capi\geos_c.cpp(145) : error C2733: second C linkage of

>         ..\capi\geos_c.cpp(144) : see declaration of 'GEOSTouches'

>..\capi\geos_c.cpp(189) : error C2733: second C linkage of 
>overloaded function '
>GEOSCrosses' not allowed
  (goes on throughout the rest of the file)
-If I drop the extern "C" in the .cpp file, other insanity ensues:
