Borland C++ Builder

[marijan2k]

Would you be so kind and help:

Does anybody has any experience with Borland C++ Builder and converting VC++ projects.

I am getting a message on very first HalloWorld project:
[ILINK32 Error] Error: Unresolved external '__stdcall irr::createDevice(irr::video::E_DRIVER_TYPE, const irr::core::dimension2d<int>&, unsigned int, bool, bool, bool, irr::IEventReceiver *, const char *)' referenced from D:\_CDESW8\TEST\3D_ENGINE\IRRLICHT-1.4.2\EXAMPLES\01.HELLOWORLD\DEBUG\GLAVNI.OBJ

What did I do:
set include path paths (irllicht\include)
put the irrlicht.dll in Debug directory
change the irrlicht.lib for use in Borland C++ (through coff2omf.exe)
import new lib to project (Project->Add to project)

The code is like this:

//---------------------------------------------------------------------------
#include <vcl.h>
#include <irrlicht.h>
#pragma hdrstop
//---------------------------------------------------------------------------
using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;
//---------------------------------------------------------------------------
//*Bc.lib in the name means that this lib is converted with coff2omf.exe
#pragma comment(lib, "IrrlichtBC.lib")
#pragma argsused

int main(int argc, char* argv[])
{

IrrlichtDevice *device =
createDevice( video::EDT_OPENGL, dimension2d<s32>(1024, 768),
16,false, false, false, 0);

return 0;
}

What did I missed?

Note: this is not my first project for converting VC++ libs to Borland environment, but here I stucked...

I have the same problem as you have. my teacher said that it is because of name manglings in the setting . but i could not solve this problem yet.

Are you sure that the comment-lib pragma is supported by this compiler? I'd try to link against the lib by different means.

You should try to remove default parameters in CreateDevice definition,
or use something like:

typedef core::dimension2d<s32> dim_type; // by darseq, bcb compat
IRRLICHT_API IrrlichtDevice* IRRCALLCONV createDevice(
video::E_DRIVER_TYPE deviceType = video::EDT_SOFTWARE,
const dim_type& windowSize = dim_type(640,480),............

See this topic:
http://irrlicht.sourceforge.net/phpBB2/ ... 31&start=0

For earlier Irrlicht version that was the trick, so I suppose that the same issue will work with Irr 1.5

I have tried to compile this file but I received these errors :
declaration synatax error in irrmath.h
and many error in file scolor.h
how can i fix this problem?

BCC doesn't support some MS defined types.
You should predefine any functions in project options ->conditional defines.
See example below:

atanf=(float)atan;cosf=(float)cos;sinf=(float)sin;acosf=(float)acos;asinf=(float)asin;tanf=(float)tan;sqrtf=(float)sqrt;atan2f=(float)atan2;fmodf=(double)fmodl;floorf=(float)floor;ceilf=(float)ceil;_DEBUG;fabsf=(float)fabs

I have not any spare time right now to try Irr 1.5, but you can add some additional types if it's necessary following Irr 1.4 example above.

Success!
