FRCSim on Windows 10 Linux Subsystem

When the Windows 10 Anniversary Update came out, Microsoft released the Windows Subsystem for Linux as a beta Windows feature, which essentially installs Ubuntu 14.04 LTS on your Windows 10 PC. A while ago I was experimenting with running FRCSim on an Ubuntu laptop I had laying around. Installing the Linux subsystem on my Windows 10 laptop got me thinking; would it be possible to install the simulator on Windows 10, using the Ubuntu subsystem? Has anyone tried this, or are there any reasons that it wouldn't work? And if you could get it to install, would you also have to install the Linux version of Eclipse in order to push code to it?

Re: FRCSim on Windows 10 Linux Subsystem

Don't think it would work, for many reasons. Biggest one of which is that FRCSim/Gazebo is going to expect to be running under the X11 Window Server, which is basically how everything you see on linux that isn't a straight-up full screen console works (press ctrl-alt-f2 or ctrl-alt-fn-f2 on the ubuntu laptop to see what I mean, same thing but with f7 gets you back to GUI mode). As well, Gazebo is going to need GTK/QT (window theming), and a window manager, and all of that. You could probably get it to work with a ton of work and Xming or something (X11 for Windows, basically), but I'd say it's not worth the effort.

Re: FRCSim on Windows 10 Linux Subsystem

I've tried it (using xming), and gazebo just crashes immediately. It's not even because of graphics, but instead because WSL's networking stack sucks

Code:

[Err] [Connection.cc:738] EXCEPTION: Unable to get local interface addresses



[Err] [Connection.cc:738] EXCEPTION: Unable to get local interface addresses

terminate called after throwing an instance of 'gazebo::common::Exception'

I bet if the networking problem were solved, then it would crash because of graphics
