MacOS Support - ERROR in input format validators: No input format validators found

Error

I am having issues with verifyproblem in problemtools/icpc. Specifically, it can't find my input format validators.

The same issue does not happen if I boot an Ubuntu Live USB into the same laptop. Is problemtools/icpc supported on MacOS? I'm not sure why the host OS would cause issues, since that is what Docker is for. Here is how I run it:

docker run --rm -it -v $PWD/crosswords/:/crosswords problemtools/icpc

Does it work if you rename input_validators -> input_format_validators (the old name)?

Yes. Does that mean problemtools/icpc is outdated?

Yep, definitely sounds like it!

It looks like it was last updated 3 years ago.

Not sure if there are plans to maintain it and keep it updated. If so, I’d be happy to help with that. Either ways, I think at least a note under Method 2 is probably needed as a warning. At first, it seemed to me as if it was the most reliable method. Maybe it was in the beginning. For now, using Method 1 on Ubuntu seems to work fine so I will continue with that.

Docker images are updated now so this is no longer relevant as far as I can tell.
