Apple has an X11 sample app. This works fine in Project Builder and
also fine in XCode as a legacy target. But if it is updated to a
native target, it claims to find a conflict for the Bool and Status
types, defined in both Xlib.h and ICElib.h. Turning off ZeroLink makes
the problems described here go away. But for the record, with ZeroLink
turned on:
Here are the errors:

It still compiles, but dies with these errors:
ZeroLink: unknown symbol '_labelWidgetClass'
X11CallCarbonAndCocoa (Upgraded) has exited due to signal 6 (SIGABRT).
So I don't really understand why the PB legacy has no errors about
type redefinition, nor why the linker dies in the upgraded target. Are
the linker flags being ignored?
In the older target, they are in the Other Mach-O Linker flags as:
-L/usr/X11R6/lib -lXaw -lXext -lXmu -lXt -lX11
They get copied to the Linker flags setting of the new native target
just fine.
Is this a known issue? Could not find any word about it in the XCode
or X11 list archives.
Cheers,
