Hello Paul,

In thread.cpp:

1) Obviously missing
#include <iostream>

2) A few syntax errors
Eg. missing "std::" in
Thread::Thread(std::auto_ptr<Runnable> runnable .....
-------------------------------------

It's best to create and use a Makefile !
------

But this is how to compile and link your code manually.

First compile thread.cpp and runnable.cpp. The result is object files
thread.o and runnable.o

g++ -c thread.cpp
g++ -c runnable.cpp

Now compile the main program (Listing1-6.cpp) and link all modules
together with the libpthread library.

g++ -o Listing1-6 -lpthread thread.o runnable.o Listing1-6.cpp

And finally run it
../Listing1-6
-------------------

Now learn howto to create and use a Makefile.
