Box2D Linker Woes

3 posts in this topic

Hey Folkz,

 

Hoping someone can help me here. this should b fairly simple.

 

I am trying to look at C++ again, so am using SFML and Box2D to create a small game, easy. I have setup SFML and have a working program, but ... Box2D! i have looked at every page on Google on how to link the .lib into my project and have followed every step to the T and i still get:

Error	1	error LNK2019: unresolved external symbol "public: __cdecl b2World::b2World(struct b2Vec2 const &)" (??0b2World@@QEAA@AEBUb2Vec2@@@Z) referenced in function "public: __cdecl PhysicsSystem::PhysicsSystem(struct b2Vec2)" (??0PhysicsSystem@@QEAA@Ub2Vec2@@@Z)	F:\Code\ShapeGames\ShapeGames\PhysicsSystem.obj	ShapeGames

Now, i know what the problem is, just not how to solve it.

 

I have added the Box2D Header to the Additional include Directories and Intelli-sense picks up the correct function definitions etc. 

I have added the .lib's path to  to both Linker -> General and the Box2D.lib to Linker-> Input -> Additional Dependencies.

 

AFAIK, the linker is even picking up Box2D.lib because if i remove the files path from Linker -> general it tells me cannot find file. So it found the file, but isn't linking it? right? wrong? what have i missed? i have followed the tutorials linked below to the word :/

 

So, i have spent 3hrs on this now. Help me Obi-wan your my only hope.

And your Box2D.lib is x64 as well? (possibly not the issue, but worth checking)
