[SOLVED] Link error while building a unit test target

Link error while building a unit test target

I have a XCode4 / iOS project with a regular target and unit test target. Everything works fine, except when I try to #import one of my classes in my test class and try to use it. If I try to build the unit test target, I get the following link error:

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_FRRCategory", referenced from:
      objc-class-ref in CategoryTests.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status

In CategoryTests.m I'm importing the header file in this way:

#import "../todoro/FRRCategory.h"

What am I doing wrong?

Solution

Make sure that the FRRCategory source file has been added to your Compile Sources for your unit test target.

Xcode 4:

Project Navigator -> "[Project Name]" -> Under Targets select your unit test target -> Build Phases -> Expand Compile Sources -> Click + at bottom of Compile sources and add the correct source file.
