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:
>> require 'ibm_db.bundle'
Please let me know if you encounter any issues, I’d be glad to help you.
