MySQL Gem installation

[Dai Le]

Hi, I'm trying to installation the MySQL gem for Ruby and I keep getting this error that I have no idea how to resolve. Has anyone ever encountered this error or have an idea of how resolve it?

I'm issuing the command:

sudo gem install mysql -- --with-mysql-config=/usr/bin/mysql_config

and I get this output:

Building native extensions. This could take a while...
ERROR: Error installing mysql:
ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb install mysql -- --with-mysql-config=/usr/bin/mysql_config
