Linking VS2010 with Assimp

Question

I have been trying to get assimp working with VS2010. I have seen many questions similar to this but I just can't get it to work. Read the installation tutorials here http://assimp.sourceforge.net/lib_html/install.html and still can't get it to work.

This is what I did for VS2010 project setup:

All Configurations -> Configuration Properties -> VC++ Directories -> Library Directories ADDED C:\assimp--3.0.1270-sdk\lib\assimp_release-dll_x64
All Configurations -> Configuration Properties -> VC++ Directories -> Include Directories ADDED C:\assimp--3.0.1270-sdk\include
All Configurations -> Configuration Properties -> C++ -> General -> Additional Include Directories ADDED C:\assimp--3.0.1270-sdk\include
All Configurations -> Configuration Properties -> Linker -> Input -> Additional Dependencies ADDED assimp.lib

When i write following code:

#include <assimp/Importer.hpp>      // C++ importer interface
#include <assimp/scene.h>           // Output data structure
#include <assimp/postprocess.h>     // Post processing flags

Assimp::Importer importer;

This is the error I get:

Error   2   error LNK2019: unresolved external symbol "public: __thiscall Assimp::Importer::Importer(void)" (??0Importer@Assimp@@QAE@XZ) referenced in function "void __cdecl `dynamic initializer for 'importer''(void)" (??__Eimporter@@YAXXZ)    C:\Users\Martin Liu\documents\visual studio 2010\Projects\MyGame\MyGame\Game.obj    MyGame

Error   3   error LNK2019: unresolved external symbol "public: __thiscall Assimp::Importer::~Importer(void)" (??1Importer@Assimp@@QAE@XZ) referenced in function "void __cdecl `dynamic atexit destructor for 'importer''(void)" (??__Fimporter@@YAXXZ) C:\Users\Martin Liu\documents\visual studio 2010\Projects\MyGame\MyGame\Game.obj    MyGame

Any help would be appreciated

I'm not familiar with that but... are you matching your app bitness (e.g. 32 bit) with the version of the libraries above (x64) ? — Marco A., Feb 15 '14 at 20:25
I think so, my comp is 64 bits and I used x64 versions do those libraries — Mantracker, Feb 15 '14 at 21:15
okay, but is the visual studio project configured as 64? VS by default creates 32bit ones. You can check this out by right-clicking in your project and choosing "properties" and then "Configuration Manager" button — Marco A., Feb 16 '14 at 08:59
ah thank you, changing them from x64 to x86 solved my problems — Mantracker, Feb 16 '14 at 18:14

Make sure your application's bitness matches your libraries' one. E.g. you can't link against x64 libraries if your project is 32 bit.

You can check this out by right-clicking in your project and choosing "properties" and then "Configuration Manager" button.
