Hello. I downloaded a library called Libnoise that generates coherent noise. It can be used for landscapes, which is why I downloaded it. You can download it here: libnoise.sourceforge.net Anyways, I'm using Microsoft Visual Studio 2008. When I tried to compile the following code, #include "stdafx.h" #include <iostream> #include <noise.h> using namespace noise; int main (int argc, char** argv) { module::Perlin myModule; double value = myModule.GetValue (1.25, 0.75, 0.50); std::cout << value << std::endl; return 0; } I get the following errors: test2.obj : error LNK2019: unresolved external symbol "public: virtual double __thiscall noise::module::Perlin::GetValue(double,double,double)const " (?GetValue@Perlin@module@noise@@UBENNNN@Z) referenced in function _main test2.obj : error LNK2019: unresolved external symbol "public: __thiscall noise::module::Perlin::Perlin(void)" (??0Perlin@module@noise@@QAE@XZ) referenced in function _main test2.obj : error LNK2019: unresolved external symbol "public: virtual __thiscall noise::module::Module::~Module(void)" (??1Module@module@noise@@UAE@XZ) referenced in function "public: virtual __thiscall noise::module::Perlin::~Perlin(void)" (??1Perlin@module@noise@@UAE@XZ) I know I correctly linked all the directories. I've looked on other sites, and found no answer. I also made threads on all the other sides and nobody replied. Can somebody please help me with this? Thank you, it's very much appreciated.

It's in the correct directory. Everything is. I made sure to link everything. Just in case, the I would link the DLL under Library files, right?

Edit:

add the libnoise.lib to your Linker\Input\Additional Dependencies, with full path if needed.

What can I say? It worked. Thanks a lot guys, it was a huge help.

I didn't know whether to start another thread, so I'll revive this one. I've run into another problem when I added two more files to the Compiler's include directory: noiseutils.h and noiseutils.cpp. I'm getting the same type of error as above, but there isn't any library to include.

libnoise.obj : error LNK2019: unresolved external symbol "public: __thiscall noise::utils::NoiseMap::~NoiseMap(void)" (??1NoiseMap@utils@noise@@QAE@XZ) referenced in function _main

libnoise.obj : error LNK2019: unresolved external symbol "public: virtual void __thiscall noise::utils::NoiseMapBuilderPlane::Build(void)" (?Build@NoiseMapBuilderPlane@utils@noise@@UAEXXZ) referenced in function _main

libnoise.obj : error LNK2019: unresolved external symbol "public: __thiscall noise::utils::NoiseMapBuilderPlane::NoiseMapBuilderPlane(void)" (??0NoiseMapBuilderPlane@utils@noise@@QAE@XZ) referenced in function _main

libnoise.obj : error LNK2019: unresolved external symbol "public: __thiscall noise::utils::NoiseMap::NoiseMap(void)" (??0NoiseMap@utils@noise@@QAE@XZ) referenced in function _main

Any suggestions?

Um, i don't think you should have a cpp in the include directory. The LibNoise documentation (assuming there is some) should tell you what .lib files to include and what header files to include.

Whoops, my mistake. I meant to say that I've linked everything correctly. And there is barely any documentation.
