Installing the Ruby driver for DB2 on Mac OS X Snow Leopard

Now that Mac OS X 10.6 is out, it’s time to leave the world of 32 bit computing behind. The pre-installed Ruby interpreter will run in 64 bit mode by default, so you may need to pay attention when installing some C-based gems. The ibm_db Ruby gem for DB2 can easily be installed or updated to the latest available version by following these simple steps:

$ sudo -s
$ export IBM_DB_LIB=/Users/<username>/sqllib/lib64
$ export IBM_DB_INCLUDE=/Users/<username>/sqllib/include
$ export ARCHFLAGS="-arch x86_64"
$ gem install ibm_db

You can verify that the installation was successful my running the following:

$ irb
>> require 'ibm_db.bundle'
=> true

Please let me know if you encounter any issues, I’d be glad to help you.

   Yes, I have a problem, when I am running the gem install I am recieving this error:

   Building native extensions. This could take a while…
   ERROR: Error installing ibm_db:
   ERROR: Failed to build gem native extension.

   /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb

   *** extconf.rb failed ***
   Could not create Makefile due to some reason, probably lack of
   necessary libraries and/or headers. Check the mkmf.log file for more
   details. You may need configuration options.

   Any ideas?
