LoadError libicudata.64.dylib with 0.7.7

[OneDivZero]

Installed as described in readme on latest OSX, installation passed without errors, but now rails does not work any more.

This might happen after you upgrade your icu4c. For example after brew upgrade. To fix it run bundle pristine charlock_holmes

I believe that this suggestion should be a part of the error message

This happens quite frequently to us. https://github.com/brianmario/charlock_holmes/pull/164 would add an --enable-static option so that icu4c upgrades don't break charlock_holmes.

[stanhu]

I think we can close this issue now that charlock_holmes 0.7.9 supports the --enable-static option:

gem install charlock_holmes -- --enable-static

This will work for macOS, but not for Debian/Ubuntu since they don't ship a static library compiled with -fPIC.

If you’re having trouble installing charlock_holmes on an M3 Mac, try this:

Install a compatible ICU version:

brew install icu4c@74

Install the gem with the ICU path specified:

gem install charlock_holmes -v 0.7.7 -- --with-icu-dir=$(brew --prefix icu4c@74)

This links charlock_holmes to a compatible ICU version and should fix installation issues on Apple Silicon(Apple M3 Pro).

Just ran into these issues after running brew upgrade. It installed icu4c@76, which evidently is not supported. Downgrading to @74 as per @MurapureddiNag comment above worked well. Thanks.

Also, --enable-static as mentioned earlier in this ticket does not work, so sticking with dynamic linking for now.

I've had no issues building charlock_holmes with icu4c@75 or icu4c@76 on Ruby 3.2.5. --enable-static also works fine.

What errors are you seeing?

[stanhu]

It's entirely possible the issue I ran into with Go in https://github.com/golang/go/issues/70209 is applicable here. The change in https://github.com/unicode-org/icu/commit/199bc827021ffdb43b6579d68e5eecf54c7f6f56 caused icu-uc to be in the Requires.private for libicu-i18n.pc:

Requires.private: icu-uc

We might need to add --static to the pkg-config command to pick up icu-uc.

However, I'm not seeing an issue:

Actually, it seems charlock_holmes already adds all the required libraries here: https://github.com/brianmario/charlock_holmes/blob/1c14a3fd5b08f629bba7ba478f8644a5296932bc/ext/charlock_holmes/extconf.rb#L33-L35

That explains the latest version works fine for me. I don't know what errors people are getting.
