If you compile with a deployment version of 10.9, I don't know if it
even bothers to look at the else clause. Try -mmacosx-version-min=10.8.
Oops, that was a typo. I meant -mmacosx-version-min=10.8. Either way,
@available is checked at runtime, so both cases must be compiled anyways.
#import <AppKit/AppKit.h>
int main() {
NSPrintInfo *info;
if (@available(macOS 10.9, *)) {
info.orientation = NSPaperOrientationPortrait;
} else {
info.orientation = NSPortraitOrientation;
}
}
Regardless, if you really need a fix, you should be able to cast
through NSInteger, instead of NSPrintingOperation, as a fallback.
I'm not sure what you mean by "cast through NSInteger", but if I say
info.orientation = (NSInteger) NSPortraitOrientation;
then there's an error, "assigning to NSPaperOrientation from
incompatible type NSInteger (aka long)”.
I’m not seeing that error at all, even with -Wall -Wextra. What flags
are you using?
Hmm, it appears to be because I'm using Objective-C++. When I put that
line in a .m file, there was no error.

I had some code like this
pInfo.orientation = NSPaperOrientationPortrait;
where pInfo is of type NSPrintInfo*. When compiling with
-Wunguarded-availability, I got a warning saying that
NSPaperOrientationPortrait is only available on macOS 10.9 and
later. So I wanted to change it to:
if (@available( macOS 10.9, * ))
{
pInfo.orientation = NSPaperOrientationPortrait;
}
else
{
pInfo.orientation = NSPortraitOrientation
}
But then I get an error, "assigning to NSPaperOrientation from
incompatible type NSPrintingOrientation". If I fix the error by
adding a typecast to NSPaperOrientation, then I get a warning that
NSPaperOrientation is only available on 10.9 and later. Is there
any way out of this roundabout, other than using a later deployment
target?
