linux builds / nim instructions

[mikesteele81]

I'd like to try out gridmonger, but I can't figure out how to build it on Linux. There are at list a few problems I'm running into:

• When checking out 'koi' and the gridmonger branch of nim-glfw, instructions say to run nimble develop. When I do that, the tool appears to download a new copy from github into a subfolder, and then use that.
• The gridmonger branch of nim-glfw sets its version to 3.3.3.0, but the version koi appears to make use of is 3.3.4.0
• After adding koi and nim-glfw (though I don't know if its the right branch), I get an error about joystick_linux.c not being found in glfw.

I'm busy with other stuff right now, I will pick up the project in a month or two to work on the next release. I will revisit the README then and I'll let you know. It seems to me most of your problems are not Linux related, though.
