The first thing on my developer itinerary after getting my MacBook Pro is to install my development tools. That includes upgrading the ruby and rails gem versions packaged with OS X 10.6 and installing Xcode which is included on Snow Leopard’s install DVD. Things proceed smoothly until I tried to install the mysql gem.
Ruby threw a fit and dumped this message:
$ sudo gem install mysql Building native extensions. This could take a while... ERROR: Error installing mysql: ERROR: Failed to build gem native extension. Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/mysql-2.8.1 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/ext/mysql_api/gem_make.out
After some google-fu, I found out that when installing the mysql gem on OS X, you need to point it to where your mysql_config file is placed. Below is the complete guide on how to how to install the mysql gem on Snow Leopard.
- Download your preferred MYSQL version from the community download site. If you’re on Snow Leopard, you may want to install the 64-bit version.
- Install mysql via dmg or compile it from source.
- Type ‘which mysql_config’ on the terminal to locate said config. Take note of this location as we’ll use it on the next step.
- Install the mysql gem with the command below. If the location for your mysql config is different with the one below, use that instead.
sudo env ARCHFLAGS="-Os -arch x86_64 -fno-common" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Note that if you’re using the 32-bit version, you have to use:
sudo env ARCHFLAGS="-Os -arch i386 -fno-common" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
- And success!
$ sudo env ARCHFLAGS="-Os -arch x86_64 -fno-common" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config Building native extensions. This could take a while... Successfully installed mysql-2.8.1 1 gem installed Installing ri documentation for mysql-2.8.1... ...
