Using Core Plot iPhone - Linker error

Question

I kept getting the following linker error when i try using Core Plot in my project...

Undefined symbols for architecture i386:
  \"_OBJC_CLASS_$_CPXYGraph\", ref         


        

Answer 1

Is this in xcode 4? You might want to make sure that you have the latest version of core plot. Xcode 4 caused a problem for me until I downloaded the latest version of core-plot and removed the previous directory.

I open the touch project and rebuilt then the linked was OK again!
