Hello Everybody I am one of the developers of a cross platform library called plib (plib.sourceforge.net), used for developing 3d games.. I know there has been alot of work done porting gl, and glu over to d, has glut been ported yet. On to my real question, is there any way to use c++ libraries. If so what do i have to do. Compile my c++ libraries(static or shared), convert c++ headers to d and compile my new d program using the d headers.. Can live be that easy or am i missing something.. Thanks Ben

What C++ libaries did you want to use?Thanks Ben

plib is the library.. have a look its a great library for working with 3d scenes, flightgear was created using it.. its at plib.sourceforge.net Later, Ben anderson wrote:"ben" <zander echotech.ca> wrote in message news:aff549$1aiv$2 digitaldaemon.com...Hello Everybody I am one of the developers of a cross platform library called plib (plib.sourceforge.net), used for developing 3d games..

Sorry I over read that. The simple answer is you can't. I read some where that Walter looked into adding c++ support but found it much to complex to interface to D. There may be other free libraries C out there that build on openGL, otherwise your stuck with openGL, directX and SDL in D. Incidently have you tried using SDL (Simple DirectMedia Layer import module) with openGL, it doesn't read any 3d file formats but it does sound, textures and lots of other things."ben" <zander echotech.ca> wrote in messagenews:affa3i$1q85$1 digitaldaemon.com...plib is the library.. have a look its a great library for working with 3d scenes, flightgear was created using it.. its at plib.sourceforge.net Later, Ben anderson wrote:

The trouble with interfacing to C++ is the C++ object model is so complex it would essentially require building most of a C++ compiler into the D compiler.

Not that easy=2E You cannot just import C++ classes from D modules=2E
There are two ways to do this=2E One is to provide a C wrapper function

=09class Surface

=09=2E=2E=2E
=09Surface=5Funlock=28logo=29=3B
=09Surface=5Fblit=28screen=29=3B
=09
Then=2C you can wrap this all into classes=2C reconstructing C++ class
hierarchy=2E
This is the most portable way=2C it'll work on any platform which has C++
and D compilers=2E But how about virtual methods=3F Well=2C you can then define
a
C++ class as a struct in D=3A
=09struct Surface
=09{
=09=09struct =5FVMT=09 =2F=2F virtual method table
=09=09{
=09=09=09PIXEL* =28*lock=29=28Surface*=29=3B
=09=09=09void =28*unlock=29=28Surface*=29=3B=09=09=09
=09=09}
=09=09=5FVMT* =5Fvmt=3B
=09}
Now you can use late binding as well=3A
=09data =3D logo-=3E=5Fvmt-=3Elock=28logo=29=3B
=09=2E=2E=2E
=09logo-=3E=5Fvmt-=3Eunlock=28logo=29=3B
Not sure if this is portable=2C though=2E I guess it works with DMC=2FDMD=2C
MSVC=2C
BCC=2C probably GCC as well=2C but it's better to check=2E

You cannot just import C++ classes from D modules. There are two ways to do this. One is to provide a C wrapper function over each C++ class method, e.g.: // C++ file class Surface { public: Surface(); void blit(Surface& target); virtual PIXEL* lock(); virtual void unlock(); ... }; // C wrappers extern "C" { Surface* Surface_Surface() { return new Surface; } void Surface_blit(Surface* _this, Surface* target) { _this->blit(target); } PIXEL* Surface_lock(Surface* _this) { return _this->lock(); } void Surface_unlock(Surface* _this) { _this->unlock(); } ... } /+++ D module +++/ // import C wrappers extern(C) { typedef void* Surface; Surface* Surface_Surface(); void Surface_blit(Surface* _this, Surface* target); PIXEL* Surface_lock(Surface* _this); void Surface_unlock(Surface* _this); } // use it Surface logo = Surface_Surface(); PIXEL* data = Surface_lock(logo); ... Surface_unlock(logo); Surface_blit(screen); Then, you can wrap this all into classes, reconstructing C++ class hierarchy. This is the most portable way, it'll work on any platform which has C++ and D compilers. But how about virtual methods? Well, you can then define a C++ class as a struct in D: struct Surface { struct _VMT // virtual method table { PIXEL* (*lock)(Surface*); void (*unlock)(Surface*); } _VMT* _vmt; } Now you can use late binding as well: data = logo->_vmt->lock(logo); ... logo->_vmt->unlock(logo); Not sure if this is portable, though. I guess it works with DMC/DMD, MSVC, BCC, probably GCC as well, but it's better to check.

I guess it works with DMC/DMD, MSVC, BCC, probably GCC as well, but it's better to check.DMC's object model (i.e. the location of the vptr) is compatible with MSVC. It's different for GCC, so some care needs to be taken there.
