Re: Building on a Mac

[Ray Donnelly <mingw.android@gmail.com>]

GCC on mac will probably be able to make you a native compiler. It
won't be able to make you a cross compiler (easily) or (even more
tricky) a canadian cross compiler. Whether you should give up or not
is up to you! Certainly technologies like docker do offer alternatives
but they come at an execution cost. For sure, I'd love to see some
patches developed to fix the issues with macOS GCC-based-toolchains in
these more exotic scenarios! I did, at some point in the distant past,
create cross compilers that ran on macOS and targeted Linux. For fun I
did the same for Windows as host.
