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

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

#ifndef NULL
#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);

No splitting of the lines is fine.

But I don't see at the moment what could cause this.

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;
