Problem with MakeFile

Hi, I'm doing a project and I added some new classes. The problem is that now the MakeFile is getting some errors!!! :(

The above is the error that shows when I do make.

The project is in this repo -> https://github.com/lazaro92/SFML_tutorial/ on the branch development.

I think is not a good idea to post the entire code here.

Anyone know which is the problem?
My makeFile is this (also it is inside the repo):

The principal problem I have to detect errors is that I'm novice with C++

you may use `nm' and see that ResourceHolder.o is basically empty
http://www.cplusplus.com/forum/general/113904/#msg622073
put the template code in the header

did a simple search and couldn't find the implementation of the constructors
Ok thanks!

The first problem I saw that in the code that I downloaded from the web of the book it uses an #include "ResourceHolder.inl" . I never saw an inl file but I imagine it's use.

The second one is a fail XD

Thanks a lot!!!

This weekend I will document all the code to finish understanding it. The problem is that I have had a little time to work on this.

perhaps the inline functions implementations
#include is simply copy-paste and extensions are meaningless

¿did you remove the repository? ¿why?
I changed it to private because it is based on a tutorial book, so in fact I (think) don't have the rights to publish it
