Error installing on MacOS 15.1
I'm trying to install version 0.7.9 on MacOS. It seems that since upgrading to MacOS 15.1 i'm getting error. I've tried setting the correct flags like explained in the README but with no luck yet.
Installing in on Linux within a docker container works fine.
This is the begin and end part of the error logs that I'm getting.

In my case, I rebuilt ruby through rvm and it fixed the issue:
rvm reinstall 3.2.1 --with-openssl-dir=/usr/local/opt/openssl
...where the symlinked version of openssl is [email protected]
I was able to solve the issue by installing the gem using the following command
export ICU_PATH="/opt/homebrew/opt/icu4c"
gem install charlock_holmes -- --with-icu-dir="$ICU_PATH" --with-cxxflags="-std=c++17"
I had trouble installing it on 15.3 (24D60). I tried various solutions, but nothing worked. Ultimately, I found a suggestion to completely remove the Command Line Tools and reinstall them from scratch, which finally solved the issue. Make sure you start fresh—no environment variables, no bundle config for charlock_holmes build, nothing.
Steps to take:
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install
bundle config --delete build.charlock_holmes
bundle config build.charlock_holmes --with-icu-dir="/opt/homebrew/opt/icu4c" --with-cxxflags="-std=c++17"
bundle
If it's not included in Bundler but you want to install it separately, do it like @samuelvaneck mentioned in the previous message.
gem install charlock_holmes -- --with-icu-dir="/opt/homebrew/opt/icu4c" --with-cxxflags="-std=c++17"
I had trouble installing it on 15.3 too.
I can install it like that with the global version of ruby set (3.3.x) like that:
sudo gem install charlock_holmes -- --with-icu-dir="/usr/local/Cellar/icu4c" --with-cxxflags="-std=c++17"
Fetching charlock_holmes-0.7.9.gem Building native extensions with: '--with-icu-dir=/usr/local/Cellar/icu4c --with-cxxflags=-std=c++17' This could take a while... Successfully installed charlock_holmes-0.7.9 1 gem installed
However, when I go to my project (local ruby 2.6.x set with rbenv), and type the same thing, i looks like it didn't find GCC !

I have tried so many things since yesterday... I reinstalled dev tools too.
I got multiple compilation errors when installing charlock_holmes v0.7.9 with Ruby 2.7.8.
Install comand:
gem install charlock_holmes -- --with-icu-dir=/opt/homebrew/opt/icu4c@76 --with-cxxflags="-std=c++17"
(It didn't work with icu4c@77 and c++11 as well.)

What's the best way to fix it? I'll happily submit a PR if required - just direct me, please. :-)
I got multiple compilation errors when installing charlock_holmes v0.7.9 with Ruby 2.7.8.
Install comand:
gem install charlock_holmes -- --with-icu-dir=/opt/homebrew/opt/icu4c@76 --with-cxxflags="-std=c++17"(It didn't work with icu4c@77 and c++11 as well.) ... What's the best way to fix it? I'll happily submit a PR if required - just direct me, please. :-)
@ilyazub, it looks like the newer versions of icu4c aren't compatible with Ruby 2.7.8 as far as I can tell.
Downgrading to icu4c@74 seems to do the job. With Homebrew:
brew uninstall icu4cbrew install icu4c@74brew link --force --overwrite icu4c@74bundle config build.charlock_holmes --with-cflags="-I/opt/homebrew/opt/icu4c@74/include" --with-ldflags="-L/opt/homebrew/opt/icu4c@74/lib"bundle install
brew tap-new old/formulas
brew extract icu4c old/formulas --version=74
brew install old/formulas/icu4c@74
gem install charlock_holmes -v 0.7.9 -- --with-icu-dir=$(brew --prefix icu4c@74)
