I have moved all my .c and .h source to a defferent directory from the one 
wherein I am building. I now get a lot of error messages of the form:
"linker input file unused because linking not done"
What am I doing wrong? Do I need some kind of flag to tell gcc where to look?
Thank You.


I now have the source and the include files in a different read only directroy: 
I am building a library:

After making this change I get a lot of messages of the form:
linker input file unused because linking not done

--sample error message.
