I examined the numerical value of NSScannedOption and decided to give
this a try in RegexKitLite.m:
#ifndef iPhone
else { if((splitStrings = rkl_realloc(&scratchBuffer[1],
splitStringsSize, (NSUInteger)NSScannedOption)) == NULL) { goto
exitNow; } } # <<<< original line 579
#else
else { if((splitStrings = rkl_realloc(&scratchBuffer[1],
splitStringsSize, (NSUInteger)1)) == NULL) { goto exitNow; } }
#endif
Now the test app link_example.m app installs and runs on a real phone.
Whether this actually solves a problem with the code running on an
iPhone, I do not know. I'm a newcomer to the Mac, and fixing one
problem may cause another. iow, my fix is naive.
I also decided to try to figure out where NSScannedOption originates,
and found this:
$ sudo find /usr /System/ /Developer/ -name \*.h |xargs grep
NSScannedOption 2>/dev/null
/System//Library/Frameworks/Foundation.framework/Versions/C/Headers/
NSZone.h: NSScannedOption = (1<<0),
/Developer//Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/
System/Library/Frameworks/Foundation.framework/Headers/NSZone.h:
NSScannedOption = (1<<0),
/Developer//Platforms/iPhoneSimulator.platform/Developer/SDKs/
iPhoneSimulator2.0.sdk/System/Library/Frameworks/Foundation.framework/
Versions/C/Headers/NSZone.h: NSScannedOption = (1<<0),
/Developer//SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/
Foundation.framework/Versions/C/Headers/NSZone.h: NSScannedOption =
(1<<0)
/Developer//SDKs/MacOSX10.5.sdk/System/Library/Frameworks/
Foundation.framework/Versions/C/Headers/NSZone.h: NSScannedOption =
(1<<0),
indicating that NSScannedOption lies completely within NSZone.h, at
least in the likely directory trees.
My guess is that the build process for the iPhone simulator config
differs from the device config in some way that includes NSZone.h for
the former, but not the latter. Or some such.
