Build failing? Problem with gfx_device_gl?

[joshburkart]

I was trying to experiment with your awesome-seeming library, but unfortunately wasn't able to install it... Any ideas? I'm running OSX High Sierra, and just updated the Rust compiler. Example error message:

That is strange. core-graphics would probably be a Mac-only dependency of SDL2, so maybe you could try using updating the SDL2 dependency, if there is a newer version out there.

In general, though, only Windows and Linux are supported by dataplotlib right now. Mac seemingly can't handle the graphics window being created and controlled by a thread other than the main thread, even though it works fine on every other system I've tested.

Thanks for the info! I'll update this issue if I figure something out...
