clang: error: while accessing a library(contains kiss xml) in sub-project

Question

We have a workspace with the below structure:

SampleProject1

SampleProject2 >>Sub-Project

---

Now, we are trying to access the SampleProject1 in Sub-Project. After setting the

Header Search Path

in Sub-Project able to access the Sampleproject1. But, the SampleProject2 is showing build error as follows:

Undefined symbols for architecture i386:   "_OBJC_CLASS_$_DDXMLDocument", referenced from:
      objc-class-ref in libMyervices.a(MyService.o) ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

In SampleProject1, we have integrated KissXML.

Thanks in advance
