Hi am trying to create a .net dll with the static library nvtrsistrip, my problem is that i don´t know c++ i have tried and it gives me 3 errors, could anyone take a look to my project to tell what i have to do? http://rapidshare.com/files/358865335/MYtristrip.rar Thank´s

How about you instead post your code and the error messages you get? Nobody is going to bother downloading and compiling your code for you.

My project is named Prc++ and it has the code of the nvtristrip that i need to compile into a dll for visual basic, i don´t know c++ i have read some tutorials and i made this:

i have added into the folder nvstrip.lib and in Prc.h i have put the code of nvstrip.h:


#ifndef NVTRISTRIP_H
#define NVTRISTRIP_H

#define NULL 0
#endif

#pragma comment(lib, "nvtristrip")

And here are the errors in the compilation:

Quote:

bool GenerateStrips(const unsigned short* in_indices, const unsigned int in_numIndices,
PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false);

void RemapIndices(const PrimitiveGroup* in_primGroups, const unsigned short numGroups,
const unsigned short numVerts, PrimitiveGroup** remappedGroups);


Put these on to single lines:

bool GenerateStrips(const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false);

void RemapIndices(const PrimitiveGroup* in_primGroups, const unsigned short numGroups, const unsigned short numVerts, PrimitiveGroup** remappedGroups);

I have put those lines in single lines, but i am still having the 3 same errors.

Now i have changed prc.h:



// Prc++.h

#pragma once

using namespace System;

namespace Prc {




enum PrimType

PT_LIST,
PT_STRIP,
PT_FAN
};



struct PrimitiveGroup

unsigned int numIndices;
unsigned short* indices;

////////////////////////////////////////////////////////////////////////////////////////

PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {}
~PrimitiveGroup()

if(indices)
delete[] indices;
indices = NULL;
}
};

but i have this errors compiling:
