I am deploying my Rails application using Chef. While

gem install mysql

am getting hte following error,

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Make sure that gem install mysql -v '2.9.1' succeeds before bundling.

I am using RHEL 6. I also have a separate cookbook for mysql installation. I tried installing Mysql manually using the yum command.

I tried

yum install mysql-devel and then run the gem install mysql

still not working. Can anyone help me out.

Thanks

Add the build-essentials cookbook to your runlist and configure it's "compiletime" attribute.

The following answer reports the same problem building the postgres gem

It sounds like you don't have a compiler. On a debian/ubuntu system, you can get everything you need to compile and build packages with:

sudo apt-get install build-essential

On Fedora/Red Hat I think it should be:

sudo yum groupinstall "Development Tools"
