Actually, Thomas has a good point.  The cookbook example 
has several problems that cause it to not compile.  

Read the comments within my attachments to see where the cookbook
led you astray. 

Build like this: 
  g++ -c testrunner.cpp
  g++ -c complexTestSuite.cpp
  g++ -o testrunner testrunner.o complexTestSuite.o -lcppunit

Then just run ./testrunner

You may need -L or -I flags to g++ if you installed cppunit
someplace non-standard. 

Hope this helps.
