Windows will tell you that "Windows has protected your computer!,"
but this is a lie. All that Windows has done is
noticed that Multiplayer Map Editor is not signed with a
very expensive code-signing certificate. This means nothing other
than that we don't have $500 per year to give to Microsoft just so that
they'll stop telling everyone that our game is malware.
Note that in Windows 8, you must click the "more info" link, which doesn't
actually give you any more information, before "run anyway" is presented.
Note that 64-bit Windows can run 32-bit programs as well.
Install Wine Bottler
which allows you to run 32-bit Windows programs in Mac OS. This video
explains how to use Wine Bottler in general.
We thought we'd be clever and save everyone from issues with shared library
versions by statically linking the executable, but of course, the
freetarded nature of Linux makes this impossible. The glibc
people can't even be bothered with understanding what "static" means:
warning: Using 'getaddrinfo' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
...but it's just as well I suppose. It seems glibc is LGPL-licensed, which means we can't statically link it anyway as the LGPL's restrictions for static linking are asinine.
So just run the Windows version under Wine. It should work well as we use Wine to test the Windows version.
