Hi--
I am rather new to XCode (Version 2.5), still reading the User Guide. I'm stumped by one thing I'm seeing that I'd think would be obvious.
I made up a little project to demonstrate this thing. The project contains three files (listed below); "test.c" #includes the other two. The first #included file declares a global variable, MyData, and sets it. The second #included file uses that variable.
The problem is, when I compile (command-K) the "test.c" file, the second #included file gets an error that MyData is undeclared. Why so?
I confess to an illusion that this doesn't happen all the time. I could swear (but I cannot reproduce) that that compile went through without errors a few minutes ago, before I changed something then changed it back. Is this possible, or should I think about changing my coffee supplier?
--Gil
//test.c #include <test.h> int main(void) { if (MyData); //stub return 1; } #include "testadd.c" //test.h //testadd.c void foo(void) { if (MyData); //<-- 'MyData' undeclared (first use in this function) } |
