Hi... I am working with brook language to realize some general purpose computing on GPU... I compile my "mathlib.br" brook file with "brcc" brook compiler and get "mathlib.cpp" file after compilation. After I get "mathlib.cpp", I add it to my VS.NET project. But when I add "mathlib.cpp" to my project and then built, some link errors occured. Can you explain me how to add my "mathlib.cpp" file into my VS.NET project successfully... (what kind of arrangements do i have to make on the link properties of my project in VS.NET or anything like ) THANKS...

Oh I think I can not explain my problem briefly...

I add my "mathlib.cpp" file to my project by using "AddExistingItem". After I add, I try to built my project but it gives link errors. I arrange the paths but can not succedded :(

Is anyone try such a thing?

Thanks...

what are the linker errors?

simply my .cpp file is like that:

int oct=20;
float *Frequency;
float *Persistence;

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

float P=0.5f;
int i;
int fin; //color info
int cidx; //index of a pixel

Frequency = (float*)malloc(oct*sizeof(float));
Persistence = (float*)malloc(oct*sizeof(float));

Frequency[0]= 0.05f;
Persistence[0]= 0.5f;

for(i=1; i<oct; i++)
{
Frequency = Frequency[i-1] * 2;
Persistence = Persistence[i-1] * P;
}

return 0;
}

after I add this file to my project and then built I hav got the following link errors:

LIBCD.lib(dbgheap.obj) : error LNK2005: _malloc already defined in MSVCRT.lib(MSVCR71.dll)

LIBCD.lib(dbgheap.obj) : error LNK2005: _free already defined in MSVCRT.lib(MSVCR71.dll)

So what is the problem?
