[Kde-games-devel] Moving KDots to KDE Review

[Minh Ngo]

Hi Ian,

Possibly it's because of the different stdlib (clang in Linux requires gcc,
but on Mac maybe it uses other stdlib
implementation), but I'm not sure about Mac. Is it possible to treat these
errors as warnings?

In the point.hpp the thing I did is just implemented a class Point that
consists from two coordinates and a hash function to store it in
std::unordered_*. Therefore please be free to change and don't fear about
breaking logic :).

Cheers,

Minh
