cx_Oracle with multiple Oracle client versions
<p>I am running Python 2.7 and am using cx_Oracle on a linux 64 bit OS.  I need to be able to run against either an 11.2 or 12.1 Oracle client since I can't be sure which client will be installed on the deployed target.  I know there are cx_Oracle built against each Oracle client.  How can I be sure that the app will work?  I should mention I am using pyinstaller to package up the application.  Is there a version of cx_Oracle the is built against both Oracle clients or am I required to have two different versions of my application...one for 11g and one for a 12c client?</p>
