Thanks for pulling the code and trying it out, jacquesm!

That kind of feedback is gold.

I have updated the README with the correct Ubuntu package details.

I think the issue with the includes is likely to do with having both SDL1 and 2 installed, and the slightly dirty way I am pulling in the header (so it works on Mac too).

I will have a bit of a think about how best to resolve that issue, likely needs some ifdefing.
