Can't build with SFML 2.3.2

I'm not sure if its SFML 2.3.2 that's causing the problem but i get the following issues while trying to build:

Thanks for the feedback, it seems the failure is in building the examples, not the lib itself. I've just tested this on mint 17, however, using a fresh build of SFML and I can't reproduce the error. It also seems odd that it can't find definitions for functions which certainly exist. Are you perhaps mixing static/shared libs somehow?

Hello & sorry for the late reply!

I have found the issue & it wasn't with sfml-tmxloader but rather with my SFML-binaries.

I downloaded the SFML 2.3.2 source, compiled & installed then everything worked as expected. Not sure why the precomiled .so files didn't work for me.
