Hi gccNewbie, >So it is really a very simple riddle. 'gcc -lmylib mysource.c' uses a function 'foo' which nm shows is defined in libmylib.a. gcc does not complain about not being able to find mylib, but it does complain that 'foo' is an 'undefined reference'. In what situation could that happen? Dependency order is important. What happens when you do: gcc mysource.c -lmylib HTH, --Eljay
