Precompiled header woes
Precompiled header woes

I hate compiler warnings. In this case I got them by working on a very
simple exercise in O'Reilly's "Building Cocoa Applications."
Specifically, the dict.m demo of NSDictionary on pp. 267-268. I know
the dictionary class well enough, but felt I ought to run it through
the command line anyway.
I got all this:
dict.m:3: warning: could not use precompiled header
'/System/Library/Frameworks/Cocoa.framework/Headers/Cocoa-gcc3.p',
because:
dict.m:3: warning: macro '__APPLE_CC__' previously defined on command
line for precomp does not match current command line definition
/System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:12: warning:
could not use precompiled header
'/System/Library/Frameworks/Foundation.framework/Headers/Foundation-
gcc3.p', because:
/System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:12: warning:
macro '__APPLE_CC__' previously defined on command line for precomp
does not match current command line definition
/System/Library/Frameworks/Foundation.framework/Headers/
NSAppleEventDescriptor.h:8: warning: could not use precompiled header
'/System/Library/Frameworks/ApplicationServices.framework/Headers/
ApplicationServices-gcc3.p', because:
/System/Library/Frameworks/Foundation.framework/Headers/
NSAppleEventDescriptor.h:8: warning: macro '__APPLE_CC__' previously
defined on command line for precomp does not match current command line
definition
/System/Library/Frameworks/ApplicationServices.framework/Headers/
ApplicationServices.h:20: warning: could not use precompiled header
'/System/Library/Frameworks/CoreServices.framework/Headers/
CoreServices-gcc3.p', because:
/System/Library/Frameworks/ApplicationServices.framework/Headers/
ApplicationServices.h:20: warning: macro '__APPLE_CC__' previously
defined on command line for precomp does not match current command line
definition
/System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:13: warning:
could not use precompiled header
'/System/Library/Frameworks/AppKit.framework/Headers/AppKit-gcc3.p',
because:
/System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:13: warning:
macro '__APPLE_CC__' previously defined on command line for precomp
does not match current command line definition
If I'm reading this right, it looks like the precompiled headers for
Cocoa, Foundation, ApplicationServices, CoreServices, and AppKit are
all hosed.
Can anybody tell me what I did wrong, and how do I fix this mess? Isn't
there a nice, neat command for recompiling the headers, and if so,
where do I find it?
