ncmpcpp failing on launch about homebrew-core HOT 5 CLOSED

This should have been fixed by afcf7e2. Have you tried brew update && brew upgrade ncmpcpp?

Unfortunately, no. I had updated and reinstalled just before posting the issue.

It did appear to me also that icu4c is pulled in by boost, and there seems to be some linking problem.

@knutaldrin Indeed, the error here is because of Boost. You should be able to fix this by rebuilding it via brew reinstall boost. (Boost gets built from source instead of using the bottle because ncmpcpp depends on it with the non-standard --with-icu4c option.)

@DomT4 Should we bump the revision of boost? It seems to be a bit silly because that's not going to change the bottles we build (those don't link to icu4c). This would also mean we'd be forcing a useless rebuild or bottle download on those who have a non-ICU Boost installation.

But without the revision bump, issues like this one will probably continue to come up, because there's no other way to trigger a rebuild for users that have installed Boost with --with-icu4c (either explicitly or as a dependency like in this case). 😿

Should we bump the revision of boost?

Normally I'd be a little "eh" about doing it for optional dependencies until we get some firm numbers to play with, but boost is cellar :any so the impact on users would be fairly minimal. No objection in this case, personally.

Bumped boost's revision in #441.
