It might be that you would prefer to start by learning more about C and your compiler first, before unix programming in C. Assuming that 'i;' at the end of the line isn't actually there, you are probably not passing an object module to the linker. Aside from letting the precompiler find apue.h, you also have to compile the code that implements those functions and link it with the object module compiled from your FE_10.c, or compile them together as someone else suggested.
