Inheriting from class template undefined reference to constructor

I am having trouble with templates and combining them with inheritance, I keep getting an error undefined reference to AssetLoader<Shader*, ShaderLoaderParameter*>::AssetLoader()'. I think there's something I don't quite grasp on templates.

#ifndef ASSETLOADER_H
#define ASSETLOADER_H

#include <iostream>
#include <string>

template<class T, class P>
class AssetLoader
{
	public:
	AssetLoader();
	T virtual load(P loaderparameter) = 0;
};

#endif

class ShaderLoader : public AssetLoader<Shader*, ShaderLoaderParameter*>
{
	public:
	ShaderLoader() : AssetLoader() {}
	Shader* load(ShaderLoaderParameter* loaderparameter) override;
	~ShaderLoader() {}	
};

#endif

Looks like you haven't provided a definition of the AssetLoader() constructor.
