Linker error with std C tool

  • Thread-topic: Linker error with std C tool

This is going to sound unbelievably stupid but I never tried to use Xcode
for a *std C tool* before, just C++, Cocoa, etc.  [Xcode 3.1.3, OS 10.5.8]

The project template works. [Hello, world!]

I created myFile.c file and its header, place them in a subdirectory of the
project directory and added that directory to the project (drag-and-drop).
main.c and myFile.c are both checked in the source list.  main.c includes
myFile.h and calls a function myFunc() in myFile.c.  myFunc shows up as a
project symbol.

The project compiles but I get a linker error:

_myFunc
symbol not found

When I check Build Results, it shows only main.o being built even though,
when I select the target, myFile shows up in the list of sources for the
tool.

If I add

#include "myFunc.c"

to main.c, there is no linker error.

I am completely bewildered.  Clearly, I'm missing something basic.  Could
someone please tell me what it is?

Thanks in advance.
