Hi,

I just loaded xcode from the cd (xcode 1.0). i was going through the
documentation - ADC Home > Documentation > Tools > A Quick Tour of
Xcode.  i found the hello world example.  it's a carbon app.  when i
try to build i get an error:

Build failed (1 error)

however, the errors and warnings in the left pane is greyed out.  whats
the error?  how do i fix?

here is the entire main.c listing:

#include <Carbon/Carbon.h>

static OSStatus PrintHello (
   EventHandlerCallRef handler, EventRef event, void *data)
{
   WindowRef window = (WindowRef) data;
   Rect bounds;

   GetWindowPortBounds (window, &bounds);
   EraseRect (&bounds);
   InsetRect (&bounds, 12, 12);
   TextFont (FMGetFontFamilyFromName ("\pTimes"));
   TextSize (48);
   TextFace (italic);
   TXNDrawCFStringTextBox (CFSTR("Hello, world!"), &bounds, NULL,
NULL);
   return noErr;
}

int main(int argc, char* argv[])
{
   IBNibRef         nibRef;
   WindowRef         window;

   OSStatus        err;

   // Create a Nib reference passing the name of the nib file (without
the .nib extension)
   // CreateNibReference only searches into the application bundle.
   err = CreateNibReference(CFSTR("main"), &nibRef);
   require_noerr( err, CantGetNibRef );

   // Once the nib reference is created, set the menu bar. "MainMenu"
is the name of the menu bar
   // object. This name is set in InterfaceBuilder when the nib is
created.
   err = SetMenuBarFromNib(nibRef, CFSTR("MenuBar"));
   require_noerr( err, CantSetMenuBar );

   // Then create a window. "MainWindow" is the name of the window
object. This name is set in
   // InterfaceBuilder when the nib is created.
   err = CreateWindowFromNib(nibRef, CFSTR("MainWindow"), &window);
   require_noerr( err, CantCreateWindow );

   // We don't need the nib reference anymore.
   DisposeNibReference(nibRef);

   EventTypeSpec eventSpec =
       { kEventClassWindow, kEventWindowDrawContent };

   InstallWindowEventHandler (window, NewEventHandlerUPP(PrintHello),
       1, &eventSpec, (void *) window, NULL );

   // The window was created hidden so show it.
   ShowWindow( window );

   // Call the event loop
   RunApplicationEventLoop();

CantCreateWindow:
CantSetMenuBar:
CantGetNibRef:
    return err;
}

thanks for your help.
