Error installing on MacOS 15.1

[samuelvaneck]

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.

Same with me on homebrew, rvm and MacOS 15.1.1. Tried all kinds of combinations in the flags for different c++ or icu4c (74, 75, or 76) as well as versions of the gem, but no luck. Am now always met with:

compiling ext.c
compiling transliterator.cpp
make: *** [transliterator.o] Error 1

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]

[samuelvaneck]

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"
