We've been going through the same exercise porting one of our 
products. I've kept all my notes in one place so that I can 
publish them as "The Compiler Writer's Guide to Linux". The 
current set of notes includes a complete program that calls 
printf from the libc shared library.

The notes are at
  http://www.mpeforth.com/arena/cwgtLinux.txt

At this stage I can't say that everything is 100%, but so far so 
good. The next task is to set up signal handlers from assembly. 
All feedback, criticism and help is welcome. The final book will 
be available as a free PDF from our website. Printed copies with 
an accompaying CD will also be available.
