Installing Oracle Instant Client on Ubuntu

The Oracle gem for Rails is ruby-oci8.

To run Radar against Oracle on Ubuntu, you need 'instant client' installed. Directions for this are here.

Radar is currently (as of 10/12) running ruby-oci8 2.0.6 gem. Hence, when installing on Ubuntu, you will run across the following in error log.

  Do you install glibc-devel(redhat) or libc6-dev(debian)?
  You need /usr/include/sys/types.h to compile ruby-oci8.

The fix is:

$ sudo ln -s /usr/include/linux/ /usr/include/sys

This is described here.
