Script fails when oci8 required

Question

I am new to ruby and I have this weird problem. I have installed ruby 1.9.3p125, Oracle11gXE(ver 11.2.0.2.0) on 64-bit Win7. I am able to run without any problems this script:

require 'watir-webdriver'
browser = Watir::Browser.new
browser.close

and also this script:

require 'oci8'
conn = OCI8.new('username/passwd')
conn.logoff

But as soon as I do this:

require 'watir-webdriver'
require 'oci8'
browser = Watir::Browser.new
browser.close

Things go wrong - I get this error:

Press any key to continue . . .

On the other hand this is working fine:

require 'watir-webdriver'
require 'oci8'
conn = OCI8.new('username/passwd')
conn.logoff

Could you help me to fix this? It seems 'watir-webdriver' has some problems when 'oci8' is required. But this might be wrong assumption - it might be some configuration problem. Thanks for your help!

Answer 1

Try the following code.

require 'watir-webdriver'
require 'openssl' # <-- Add this line to load openssl.so before oci8.
require 'oci8'
browser = Watir::Browser.new
browser.close

The LoadError is raised when openssl.so is loaded. As far as I tested, loading openssl after oci8 produces same error and the inverse works fine.
