[BUG] Won't start on MacOSX?

[TheEvilDev]

Describe the bug I'm not sure if this is a bug, or more just because I am a noob when it comes to C++, but I followed the brew instructions for MacOSX platform support, and recompiled it from source with cmake and make install. No issues with any of this, but when I run the program, I get the following output. I expect I'm missing some dependencies in the right places.

Here's the log output when I run the MK404 cli:

~/w/e/MK404 ❯❯❯ ./MK404                                                                                                                                                                                      ⏎ master ✱ ◼

freeglut (./MK404): failed to open display ''

Seems like it's almost there, and my issue might just be the last line, and something isn't quite right with my freeglut setup, but I just don't have much to go on, so am hoping for some guidance.

Desktop (please complete the following information):

• OS: MacOS Catalina
• Version: 10.15.7

Additional context Add any other context about the problem here - printer model, what firmware file you are running, etc.

This sounds like it cannot find a display server to connect to.

If memory serves, you need to manually start an instance of XQuartz before trying to launch MK404. If it still gives you the same error, you may need to explicitly tell it the display name to use, e.g. if the XQuartz output says something about Display :0 then the syntax is DISPLAY=:0 ./MK404 ...

Let me know if that fixes it, if so I'll update the documentation.

Actually, thanks for the quick response, turns out all I needed to do was reboot, it's working now, thanks for the great work on this project!

Ah, fantastic! I'll add a note to the wiki.
