I was testing SDL2 after installation, and this is what happened. It ran into a problem when image.load() was called. Any ideas on why this is happening

Was .../tutorials/04-drawing/ your current directory when you ran that script?

The relevant line:

local img = trySDL(image.load, "Lua-SDL2.png")

Tries to find Lua-SDL2.png in the current directory; it does not guess where the script folder is.

In other words, you should be running:

04-drawing$ lua tutorial.lua

And not:

luasdl2$ lua tutorials/04-drawing/tutorial.lua

Have you gotten things working?

Actually, luasdl2 worked fine on my laptop. The error only happened on my other machine, and I guess it is just a distro inconsistency. Thank you for the help.
