When gem install with --with-mysql-dir, the mysql2.so library does not link libmysqlclient.so.

Hi there,

I'm facing this issue with mysql2-0.5.3 when trying to install Redmine on CentOS 8.

I first install it using
$ gem install mysql2 -- --with-mysql-dir=/usr

Then uninstall the gem and set the bundle config
$ bundle config set build.mysql2 --with-mysql-lib=/usr/lib64/mysql --with-mysql-include=/usr/include/mysql
$ bundle install

In both case the installation of mysql2 went well but then this error occur
$ bundle exec rake generate_secret_token ruby /home/redmine/.rvm/gems/ruby-2.6.5/bin/rake generate_secret_token: symbol lookup error: /home/redmine/.rvm/gems/ruby-2.6.5/gems/mysql2-0.5.3/lib/mysql2/mysql2.so: undefined symbol: mysql_server_init
$ bundle exec rake db:migrate RAILS_ENV=production ruby /home/redmine/.rvm/gems/ruby-2.6.5/bin/rake db:migrate RAILS_ENV=production: symbol lookup error: /home/redmine/.rvm/gems/ruby-2.6.5/gems/mysql2-0.5.3/lib/mysql2/mysql2.so: undefined symbol: mysql_server_init

If I follow the link above it seems to say that the fix has been merged since 0.5.2 but I have 0.5.3.

Please note that I'm using MariaDB server installed with their repository.

Regards,

@glouton 1. Please open a new issue. 2. I don't follow why you're using any config options at all. Your libraries are in a standard location. The build auto-detects standard locations by default.
