libgif.so: cannot open shared object file: No such file or directory

Question

I am having an issue loading the giflib ffi module (https://github.com/leafo/giflib) in my Lapis web application running in Docker.

Here is the relevant information: https://hastebin.com/ojodidodoj.nginx

libgif.so seems to be able to be found since there is no Lua module search output, yet it says that libgif.so cannot be found, so I am very confused by this error, unless I am misunderstanding the output here?

Edit: Here is the Dockerfile: https://hastebin.com/inezemogux.rb

Answer 1

I ended up having to execute ldconfig to update the lib cache.
