Constructor can't find appropriate definition, and 100 other errors out of nowhere?

I'm trying to write a wrapper for Bullet physics for implementing into my game framework.

I have 3 classes, mDebugDraw is an implementation of the bullet debug drawing.

mRigidBody is a container for bullet's rigid body stuff.

World is a container for bullet's world stuff.

I have ~100 errors in visual studio, and almost all of them are coming from where I'm trying to create mRigidBodies, the errors are "cannot convert from initializer list to mRigidBody", "no appropriate constructor available", as well as weird ones like "mRigidBody::mRigidBody(std::string) member function is already defined or declared", which isn't a function I have implemented.

world.h contains the definitions for those three classes:

#pragma once
#include <btBulletDynamicsCommon.h>
#include <BulletCollision\CollisionShapes\btBoxShape.h>
#include <GL/glew.h>
#include "LinearMath\btIDebugDraw.h"

        {

            to = ito;

    mRigidBody(std::string name, World::shapeTypes type, glm::vec3 extent, glm::vec3 startPosition, float mass, float friction, float restitution);

    btRigidBody* getBody() { return rigidBody; }
    int getIndex() const { return index; }
private:
    btCollisionShape* mShape;
    btRigidBody* rigidBody;
    std::string name;
    int index;
    //btDefaultMotionState * mMotionState;
};

class World
{

protected:
    World();
public:
    enum shapeTypes
    {
        sphere,
        cube,
        capsule
    };
    static World * gameWorld();
    void init();
    btDiscreteDynamicsWorld* physicsWorld;
    std::vector<btBoxShape> hitboxes;
    mDebugDraw debugDrawer;
    void drawWireframe();
    mRigidBody* getRigidBody(std::string name) const;
    void addRigidBody(mRigidBody* _body, std::string _name);
    std::map<std::string, mRigidBody *> getMap() { return mRigidBodies; }
private:
    static World *mInstance;
    std::map<std::string, mRigidBody *> mRigidBodies;
};

the majority of the errors come from these two lines in world.h, where I'm defining the two constructors.

mRigidBody(std::string name, World::shapeTypes type, glm::vec3 extent, glm::vec3 startposition);
mRigidBody(std::string name, World::shapeTypes type, glm::vec3 extent, glm::vec3 startPosition, float mass, float friction, float restitution);

Here's the full list of errors.

Thanks in advance for any help, I've been struggling with this for a day now.

Solution

World is used before it's declared. In the definition of mRigidBody's constructors you refer to World::shapeTypes but World is only defined later in the file. Try placing the definition of World before mRigidBody. You may need to forward declare mRigidBody before defining World.
