Hi guys I am really new to mac and I am a little confused and having some linker problems in Xcode (c++)... I am using npp2 repository and I am trying to compile an example but I got a lot of errors. What could be the problem ? please any help appreciated. I am showing some of the errors.
Undefined symbols for architecture x86_64:
