RoR + XAMPP + MySQL -- Gem Install MySQL Issue - mysql

Question

I am PHP developer by trade and I work with XAMPP. I have decided to dive into Ruby now and I want to use the MySQL installation from XAMPP for Ruby and I am having a problem getting the Gem for mysql to install properly.
The command I am executing is this:
sudo gem install mysql -- —–with-mysql-config=/Applications/XAMPP/xamppfiles/bin/mysql_config
and the error I get is this:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/mysql-2.9.1 for inspection.

An error occurred while installing mysql (2.9.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.9.1'` succeeds before bundling.
If I do a locate mysql_config, I get this:
/Applications/XAMPP/xamppfiles/bin/mysql_config
/Applications/XAMPP/xamppfiles/bin/mysql_config_editor
/Applications/XAMPP/xamppfiles/man/man1/mysql_config.1
/Applications/XAMPP/xamppfiles/man/man1/mysql_config_editor.1
I have gone through all of the help requests on SO and I cannot find a solution to my particular problem.
Any help would be appreciated. Please let me know if you need any further information.
Thanks!

Answer 1

This worked for me on MacOS X High Sierra using RubyGems:
gem install mysql2 -- \
--with-mysql-config=/Applications/XAMPP/xamppfiles/bin/mysql_config \
--with-mysql-dir=/Applications/XAMPP/xamppfiles/mysql/ \
--with-mysql-lib=/Applications/XAMPP/xamppfiles/lib/mysql/ \
--with-mysql-include=/Applications/XAMPP/xamppfiles/include/ \
--no-ri --no-rdoc

Answer 2

I figured out with this:
bundle config build.mysql --with-mysql-config=/Applications/XAMPP/xamppfiles/bin/mysql_config
gem install mysql2
my client:
require 'mysql2'
client = Mysql2::Client.new(:host => "127.0.0.1", :username => "root")

Answer 3

I notice the OP had XAMMP installed. Here is what I had to do to get this to work after installing XAMPP. I warn you that this is not elegant, but it does allow you to avoid a second installation of mysql
# first, fake the location of the headers
sudo ln -s /Applications/XAMPP/xamppfiles /usr/local/mysql
# second, let the libraries etc show up where they are expected:
cd /usr/local/mysql/lib/mysql
for i in ../libmysql*; do sudo ln -s $i .; done
# and finally, one last hack for dynamic loading to work
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
I warned you that it was a bit ugly :-)
