The Joy of Linking

September 21st, 2007

Wouldn’t you know it - in my various console stress test apps that I wrote I had no issues compiling and linking.  Now that it’s time to integrate with my existing app that uses the Oracle libs - now I’m having linker errors everywhere. 

It looks to be a conflict between memory managers … oh… joy.

They say understanding and fixing linker errors is the sign of an experienced programmer.  I just think of it as annoyingly time consuming.

  • definition for item A couldn’t be found
  • track down item A
  • Oh look - there are several of them - which one should I use?
  • Are there any defines that need to be set?
  • Are there project dependencies that I skipped?
  • Are the two projects using the same C Runtime?  Static/Dynamic and SingleThread/MultiThread?
  • summon archaine knowlege about one of the projects your linking to - you seem to remember some mentioning how it wasn’t compatable with something & it’s not documented in the headers ;-)
  • re-compile
  • Lather, Rinse, Repeat
