OS X 10.4.10  
ruby 1.8.4 (ruby installed using [http://rubyosx.rubyforge.org/](http://rubyosx.rubyforge.org/))

Trying to install riuby-mysql 2.7.4

Every blog & refc I can find doesn’t work.

Using gem fails. Tried all the suggestions found on blogs.

Using the native package from [tmtm.org](http://tmtm.org) fails, but I get further with it.

One tip I picked up which helps the native install to get further along  
was to add “#define ulong unsigned long” at the top of the mysql.c file  
(which does not exist with the gem install).

after I make install I get this response  
/usr/bin/install -c -m 0755 mysql.bundle  
/usr/local/lib/ruby/site\_ruby/1.8/universal-darwin8.0

then I try to do a simple two liner just to see if I get complaints

#! /usr/local/bin/ruby  
require ‘mysql’

and indeed I get this complaint:

/usr/local/lib/ruby/site\_ruby/1.8/universal-darwin8.0/mysql.bundle:  
Failed to load  
/usr/local/lib/ruby/site\_ruby/1.8/universal-darwin8.0/mysql.bundle  
(LoadError)

I’m no C geek, so I have no idea what to try next.

Ideas?

btw the gcc I have installed is 4.01

looking closer, after make I get all this rot which maybe is meaningful  
to someone. it looked to me like it’s just recognizing that there’s no  
intel CPU, but maybe something in here is problematic?

I got it to work. Applied 25 years of engineering in various fields and  
disciplines… and guessed. I’ll write up details in a while, but just  
wanted to say I managed to hack it into working.

The gist of the trouble is that if you have a PowerPC Mac, the  
instructions don’t work as they assume an intel-based Mac.

I figured it out, and wrote up in detail what it took to make it work  
for me.
