[Marv2.0]

Thanks again… I was running make inside the linux folder. So now that I’m running it from the correct folder (/opt/retropie/supplementary/SDL2-2.0.1/) I get further…although I’m not successful just yet :)

I copied the SDL_udev.c from CrazySpence’s github and WinSCP it to /opt/retropie/supplementary/SDL2-2.0.1/src/core/linux. I then ran the make command from /opt/retropie/supplementary/SDL2-2.0.1/ and get a bunch of errors like the below. I think I’m just going to get a keyboard encoder and attach the joystick hardware via USB…that being said if you guys feel good about giving me a helping hand on what all these errors may mean, I would greatly appreciate it! Thanks in advance.

*I didn’t copy/paste the entire error output*
