I did “sudo gem uninstall mysql” and I found out there are two gems installed. After uninstalling the gems, I “sudo env ARCHFLAGS=”-arch x86_64″ gem install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config”. Works fine now.

If it’s not a production server i suggest just install MySQL x86 version and reinstall the gem.

I also just ran into this exact issue with DataMapper’s do_mysql gem. After pulling out my hair for a while I compiled mysql by hand and re installed the gems and everything worked perfectly after that. Hope this helps *someone*.

This article goes into more detail on the problem involving x86 versions of mysql http://craiccomputing.blogspot.com/2008/11/installing-rails-22-on-mac-os-x-mysql.html

If you are using a 32-bit version of Ruby, you won’t be able to use the mysql gem with the 64-bit version or mysql (irrespective of the arch directive).

Instead, you can install the pure Ruby MySQL interface from here:

OK, seriously. I have a REAL solution that actually works though it’s a pain in the ass. You install MySQL 32-bit and then build and link the gem against that and then binary hack the resulting mysql.bundle to use the correct location for the 32-bit libs.

Sorry, that’s “-arch x86_64″. I copy and pasted directly, not my modification.

Chris’ post didn’t work for me because it couldn’t find the x86_64. What did work was

sudo env ARCHFLAGS=”-arch ppc64″ gem install -V mysql — –with-mysql-include=/usr/local/mysql/include/ –with-mysql-lib=/usr/local/mysql/lib –with-mysql-config=/usr/local/mysql/bin/mysql_config –with-mysql-dir=/usr/local/mysql

I did a lot more research on this problem with mysql bindings for Ruby. In a nutshell, I eventually bailed out and installed the 32-bit version. Details here:
