type specifier required for class

Question

I am trying to use my class ResourceManagement in my levelmanager, so that I can start creating resources.

however I get the following error(s)

Severity Code Description Project File Line Suppression State Error C4430 missing type specifier - int assumed. Note: C++ does not support default-int levelmanager.h 49

Severity Code Description Project File Line Suppression State Error C2143 syntax error : missing ';' before '*' Diabro levelmanager.h 49

I have declared the ResourceManagement class as followed in the LevelManager.h

private:
    Ogre::Entity* _playerEntity;

    ResourceManagement* mgr;

and then use it like this in the LevelManager.cpp

mgr->createResource("Diabro\Diabro\media\models", "MESH", "ninja.mesh",  "Mesh", "meshes"); //location of file, codeType of resourcetype, name of resource, type of resource, resourcegroup
    mgr->loadResource("meshes");
    mgr->reloadResource("ninja.mesh", "meshes");
    mgr->unloadResource("ninja.mesh", "meshes");

ResourceManagement class

void ResourceManagement::initialize()
{

_groupManager == new Ogre::ResourceGroupManager;
}

void ResourceManagement::createResource(std::string pLocation, std::string pLocType, std::string pResourceName, std::string pResourceType, std::string pGroupName)
{
    _groupManager->getSingleton().addResourceLocation(pLocation , pLocType);
    _groupManager->getSingleton().declareResource(pResourceName, pResourceType, pGroupName);
    _groupManager->getSingleton().initialiseResourceGroup(pGroupName);
    // Ogre::ResourceGroupManager::getSingleton().initialiseAllResourceGroups(); can be used to just load all, need decision which we want
}


void ResourceManagement::unloadResource(std::string pResourceName, std::string pGroupName) // unloads a single resource
{
    Ogre::ResourcePtr ptr = _resourceMgr->getResourceByName(pResourceName);
    ptr->unload();
    _resourceMgr->remove(pResourceName);    
}


void ResourceManagement::unloadResourceGoup(std::string pGroupName)
{
    _groupManager->getSingleton().unloadResourceGroup(pGroupName);

}

void ResourceManagement::loadResource(std::string pGroupName)
{
    _groupManager->getSingleton().loadResourceGroup(pGroupName);
}


void ResourceManagement::reloadResource(std::string pResourceName, std::string pGroupName)
{
    Ogre::ResourcePtr ptr = _resourceMgr->load(pResourceName, pGroupName);
    ptr->escalateLoading();
    ptr->reload();

}
