question about .net conventions

[stubert]

in the .net environment, how do you include precompiled object files?

 

like in unix we have .o files which can be pre compiled and then included in a makefile

 

 

but how do you tell a .net soultion to include pre-made .obj files?

 

 

the reason i ask this is cause i'm working on a meathod to catch wallhackers/aimbotters etc and it requires C++, and to get that to workin the jk3 library you need to precompile the C++ object then include it in the final build

 

 

the anti cheat thing is also probably a good idea to share around with the modders, as long as the source isn't released publicly becase then it will be subject to hacking

[stubert]

i can make full C++ calls from jk3 source now

I've been a bit wary about doing C++ calls in the .dll code because you have to have a method that works with your windows compiler and your linux compiler.

 

Let us know if you've come up with a method that works for both.

i have to bulld a static .lib written in C++

 

the main header for the lib looks like this

 

#ifndef CPP_H
#define CPP_H



#ifdef __cplusplus
extern "C" {
#endif 

   void test_pp(void);


#ifdef __cplusplus
}
#endif 


#endif 

 

 

this is included in the buld for cgame and the c++ lib

 

in cgame i include this in cg_local.h and it's one of the headers in the lib

 

 

void test_pp() looks like this in the lib

 

 

#include <stdio.h>
#include <stdlib.h>

#include "CPP.h"

extern "C" void Com_Printf( const char *msg, ... );


extern "C"  void test_pp(void)
{
  Com_Printf("this is a msg from c++!");

}

 

 

to create a static lib, in .net go to new project -> win32 project

 

then in the wizard that comes up click applications settings and check static .lib

 

 

then go into proteries of cgame, go to linker->inpuit and add the .lib name to the "additional depenancies" list

 

you will also need to put it in one of the .lib paths that .net looks for in tools->options->projects->VC++ directories (show directories for library files)

 

 

 

now you'll be able to add a consolecommand call to test_pp() in cgame and see the message written in the C++ modules

 

this guide also helps to do further stuff

btw, bow to me now

[razorace]

Neat, has anyone tried with the Linux compiles yet?

[stubert]

in linux you just make a .o with GCC and then copy it to your build directory and add it to your makefile

[razorace]

Well, I mean, has anyone actually tested that one with the linux compiling? I'm concerned that it might be unstable.

[stubert]

it's all the same machine code in the end

[razorace]

In theory, yes, but this isn't something that .dll support of JKA was designed for. There could be stability issues or maybe slowdown.

 

I'm just a bit paranoid about these sort of things.

[stubert]

it still doesn't matter, the dll is stored as assembler no matter what

 

 

fear not, all will be well

[Wudan]

Shouldn't cause any slow-down at all.

[ensiform]

exactly

[Wudan]

I am curious though, how much power this gives me - I'm guessing I'd be able to get information about the OpenGL context, and then start pushing polygons to it with this code - isn't that a potential security issue?

[stubert]

i am setting up a way to use this to query windows for the name of each file in memory and their path

 

then i'm going to find their md5 sums and check that against a list of know wallhacks and such

 

but, we still don't have the names of what void functions are in the .exe but i supposse you could find a way to use regular opengl calls

 

 

 

wudan: security issue for who =p

[CortoCG]

A national security issue of utmost importance =P.
