How do I get rid of these warnings?
- by Brian Postow
This is really several questions, but anyway...
I'm working with a big project in XCode, relatively recently ported from MetroWorks (Yes, really) and there's a bunch of warnings that I want to get rid of. Every so often an IMPORTANT warning comes up, but I never look at them because there's too many garbage ones. So, if I can either figure out how to get XCode to stop giving the warning, or actually fix the problem, that would be great. Here are the warnings:
It claims that <map.h> is antiquated.
However, when I replace it with <map>
my files don't compile. Evidently,
there's something in map.h that isn't
in map...
this decimal constant is unsigned only in ISO C90
This is a large number being compared to an unsigned long. I have even cast it, with no effect.
enumeral mismatch in conditional expression: <anonymous enum> vs <anonymous enum>
This appears to be from a ?: operator. Possibly that the then and else branches don't evaluate to the same type? Except that in at least one case, it's
(matchVp == NULL ? noErr : dupFNErr)
And since those are both of type OSErr, which is mac defined... I'm not sure what's up. It also seems to come up when I have other pairs of mac constants...
multi-character character constant
This one is obvious. The problem is that I actually NEED multi-character constants...
-fwritable-strings not compatible with literal CF/NSString
I unchecked the "Strings are Read-Only" box in both the project and target settings... and it seems to have had no effect...
