Dear List,
ld: Undefined symbols:
vtable for AUFlanger
translation: you've declared a virtual method but failed to provide an
implementation. I believe that normally, when you get an error about a
missing vtable, you're missing the first virtual method. It's often a
destructor.
Can anyone tell me:
1) What is the best way to begin writing an effect AU?
2) What is the proper target?
3) What are the proper compiler settings if they vary from the
SampleEffect
example?
I would just follow the sample effect; it should be set up correctly.
4) Are there any additional ways to clarify linker issues in XCode?
I remember that CodeWarrior used to spit out pretty much the same
linker error for the same problem... I don't know if it still does.
