Can't run Picam.Camera.start_link() #33

Closed aplisov closed 5 years ago

aplisov commented 6 years ago

I've installed a fresh version of Raspbian as well as Elixir and Nerves. I also downloaded this file and moved it into /home/pi. When I SSH into the file picam/lib/picam, I open up iex and type c("camera.ex"). Once I do this, it says [Picam.Camera] which I assume is correct. However when I go to run Picam.Camera.start_link() I get the following error. image

Any help is much appreciated.

@TheHardestBunnyAlive Hi! So you are not using this in a Nerves application? Is this still an issue or can we close this out?

I ended up not using picam because I couldn't figure out the issue. You can close it.

It looks like the issue is that elixir_make would normally have compiled a C-based application that Elixir is trying to call. When you manually compile the Elixir code like this, the binary application isn't available where it should be. mix compile before running IEx should solve this in case someone else happens upon this issue in the future.
