First, might I suggest that you ask these types of questions on the plug-devel list. That is what it is for.
Second, it looks to me like you are not including a standard header file. Maybe you missed putting it in at the top of your module. Something like "#include <stdio.h>"
Third, it would be helpful to see the code or a part of it to know more of the full story.
I'll be watching the plug-devel list...

<BODY>
Somebody please explain what I'm doing wrong here. I'm trying to work on some of my Advanced Placement computer science AB projects here at home. Well, I typed in the code, checked it twice and ran 'gcc main.cpp' to no avail. First it gave me warnings about textspace standard so I fixed the code to make it recent (the book is 1994) and tried again. I now get all kinds of linker errors:<BR>
