This seems related to another discussion. possibly being built into the wrong place. Looking into it.

@ray-sh Can you recheck with scenic_driver_glfw 0.10.1 and scenci_new 0.10.3? I'd expect it to work with those versions.

[smedegaard]

To others that may have this kind of error: check if you have a MIX_TARGET set to for example rpi3. I blanked my MIX_TARGET. That solved it

[wilsonsilva]

I fixed this by installing glfw3 and compiling scenic_driver_glfw manually:

brew update
brew install glfw3 glew pkg-config

mix deps.compile scenic_driver_glfw
mix do deps.get, scenic.run

I just had the same issue with the initial code delivered by mix scenic.new.

I could start my app, bypassing this issue, by setting MIX_TARGET=host, or removing targets: :host from scenic_driver_glfw dependency, which is default on the starter code.

I think the Getting Started documentation should be changed to include this, or remove targets: :host as default config for scenic_driver_glfw.
