FFI and PHP

[devnix]

Hi! I'm trying to call Chipmunk's FFI from PHP.

I think I'm almost there, but the header files have some issues when parsed by PHP's FFI. Right now I'm running cpp -P -D "__attribute__(ARGS)=" ~/tmp/Chipmunk2D/include/chipmunk/chipmunk.h -o include/chipmunk.h to get an already pre-processed header file, and I'm removing the #include <stdlib.h>. #include <math.h> lines for now.

My actual problem is a FFI\ParserException: ';' expected, got '{' at line 4 error when trying to load the library.

static inline cpFloat cpfmax(cpFloat a, cpFloat b)
{                                                        // This is line 4
 return (a > b) ? a : b; 
}

This is my first experience implementing a FFI. There's something I would need to consider? Should I curate my own .h file and write manually there the definitions as I'm needing it?

Maybe could be worth to investigate if a tool like SWIG would help making the library more friendly to make bindings?

Well, I guess I made some progress manually removing the implementation of those inline functions (for example, turning it like static inline cpFloat cpfmax(cpFloat a, cpFloat b)).

But it seems like those functions are not implemented in the dynamic library, so I can't access to them!
