I am the author of a C library called Panda. It has about 100 exported functions, and I had a need to produce a C++ wrapper for the library... I didn't really want to manually maintain a C++ version of the headers, so I wrote objectify, which is a simple perl script which will do it for me.
An example:
The first step is to make sure that objectify knows which methods and classes to export. You do this by defining two empty macros:
#define SUPPRESS(x)
#define INTERNAL
SUPPRESS means that the class x wont be exported, whilst INTERNAL stops the specific method listed from being exported. For example:
SUPPRESS(panda_object)
INTERNAL void panda_dbopen (panda_pdf *);
INTERNAL void panda_dbclose (panda_pdf *);
INTERNAL void panda_dbwrite (panda_pdf *, char *, char *);
INTERNAL char *panda_dbread (panda_pdf *, char *);
Objectify will then go through the header, and use the pointers which are passed around to determine what is a class and what isn't... stdout will be the header, stderr is a log of what objectify did...

The latest code for Objectify can be found in my online CVS server here.

This release fixes a bug where way too many methods were included under the parent class. We now also generate IDL on demand (although the IDL has not been completely tested yet).
Get the code here.
