Compileing problem.

[SirSami]

I was making a project with a raknet. Until a error appeared, the code was not compiled. Then I tried to test tutorial if that works. But it doesn't work. Same problem... It is saying something about Linker error and compile log says:

Code: Select all

make.exe: *** [Project1.exe] Error 1

What can be the problem? Everything is fine but if add peer = RakNetworkFactory::GetRakPeerInterface(); line to my program it doesen't compile it. But if I only define a peer like this: RakPeerInterface *peer;
, it works well.

While I'm not exactly sure why you ask questions about RakNet on an Irrlicht forum, this looks like you don't link to the library containing those functions.

Creating an executable in c/c++ has two steps. In the first step modules are compiled and you can reference to other modules by including certain headers. You do that.

But after the compilation those modules must be linked together in the second step. I don't know how that library is called, but if it's name is for example libRaknet.a then for linking to it you would have to add the following parameter to the g++ commandline: -lRaknet

I had the same problem once. If you're using Dev Cpp, you have to recompile RakNet. That should do it.
