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.

LoadError: dlopen(/Users/xxx/Projects/DTAG/td-wowi-shop-backend/vendor/bundle/ruby/2.5.0/gems/charlock_holmes-0.7.7/lib/charlock_holmes/charlock_holmes.bundle, 9): Library not loaded: /usr/local/opt/icu4c/lib/libicudata.64.dylib

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

[stanhu]

This happens quite frequently to us. #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 golang/go#70209 is applicable here. The change in unicode-org/icu@199bc82 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:

[stanhu]

Actually, it seems charlock_holmes already adds all the required libraries here:

charlock_holmes/ext/charlock_holmes/extconf.rb

Lines 33 to 35 in 1c14a3f

	pkg_config("icu-i18n")
	pkg_config("icu-io")
	pkg_config("icu-uc")

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