Debugging a Linking Error

  1. Is library referenced in the link command?

  2. Does the library have the method?

nm <library path> | grep -i <method name> | grep -v " U "

Note: if the symbol type is lowercase 't', then the symbol is not exported!

  1. Are both libraries/executables compiled with or without RTTI?
