Docker Compose libcups.so.2

[danielchild1]

When I use docker compose up I get caught on the the error error while loading shared libraries: libcups.so.2: cannot open shared object file: No such file or directory. So I go into the Dockerfile and add libcups2 to the end of the apt-get install -y line. Once I rebuild and run it gives me a symbol lookup error: /usr/sbin/cupsd: undefined symbol: _cupsArrayStrcmp Error.

I am wondering if I am needing to do some more prepwork before running this docker container. Is there documentation for the docker-compose.yml? I cannot find it. Thank you!

Hey @danielchild1 I am having same issue... did you find way to solve it?

@michaelrsweet by any chance can you bring us some light here? Thank you so much.

The current Github master code should work better. Linux needs the "ldconfig" command to be run, otherwise the cache of symbols in libcups.so.2 isn't updated, and that can prevent programs using the newer functions from working. I also cleaned up the Docker stuff so that it would build properly (although a fully-functional Docker image will really depend on more of the OpenPrinting components...)
