RVM Ruby 1.9 and the MySQL Gem — Friends at last on x86_64

admin — Sat, 14 Nov 2009 01:56:51 +0000

One of our production Rails apps is running on Ruby 1.9. The problem this introduces is that our dev environments must be able to run multiple versions of Ruby side-by-side. There’s nothing unique about this, it comes with the Ruby/Rails territory. After upgrading to Snow Leopard, I decided to give Ruby Version Manager a try. The install of RVM and the subsequent Ruby installs were a breeze. However, when it came time to install the MySQL gem, I ran into a brick wall. No matter what I tried, I kept getting install errors.

I’m running the standard MacOSX package install from mysql.com (Mac OS X 10.5 x86_64). I tried setting my ARCHFLAGS to the correct architecture, pointing to the correct config, and nothing helped. After Google turned up nothing, I decided to bother the nice folks in the #rvm channel. There I was given a handy little tip that goes as follows:

Uninstall the version of Ruby you’re trying to install the MySQL gem on
place the following in your ~/.rvmrc file:
```
rvm_archflags="-arch x86_64"
```
Reinstall Ruby using RVM
Install the ruby gem:
```
export ARCHFLAGS="-arch x86_64" ; gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
```
(use the correct path to your MySQL config file. If you installed mysql with MacPorts, it will be in /opt somewhere).

The problem turned out to be that RVM was not installing the x86_64 version of Ruby 1.9. And if Ruby’s architecture doesn’t match MySQL’s, then you have problems. Once they match, then it’s back to Ruby bliss.

The Sound of Freelance…

…is silence.

I had the best of intentions. I wanted to give you words. Words to make you laugh. Words to make you cry. Words to excite, enlighten and inspire.

So what happened?

Code. Code happened. I’m up to my eyeballs in freelance work. Many of you know first hand how busy things can get when you work full-time, and also take side jobs. There may be relief soon. My previous employer is finally beefing up his stable of monkey’s. These monkey’s will soon take over the work I’ve been handling since I left the outfit last July. This will hopefully free up some evening time so I can finally write some decent articles. I’m making a list, checking it twice, and will begin authoring soon.

Stay tuned. I plan on doing some small articles soon, as well as a book review.

Maybe.

Escaping the Matrix

Last weekend my wife and I went away for a four day get-away at a resort hotel. Initially I had the idea I would take my laptop along just in case the hotel had wi-fi. After a bit of consideration, I decided against it. After all, it’s a vacation, right?

After we arrived, I noticed in the hotel information that there was a business center with high-speed internet and public computers. So naturally, I checked to make sure I knew where it was during our tour on the first day. You know, just in case.

However, after a couple of days, I began to realize I CAN live without this thing called the internet. At least for four days. This may not seem like a big deal to some of you, but those four days were by far the longest I’ve gone “unplugged” in the past, oh, decade I think. Sad but true.

But at least now that I know it can be done, I won’t have to do it again. My poor inter-web, I will never leave you alone for so long again.
