since i’m in kind of a pissy mood anyways …
apple, i’d like to thank you for making me waste a solid 45 minutes fixing
various and sundry pointers because you decided that moving everything from
/Developer to /Applications/Xcode.app/Contents/... was a productive way to
facilitate an “upgrade”. this results in all sorts of unexpected behaviors.
like oh say, an inability to find stdio.h.
some quality time with xcode-select and its associated manpages as well as
some judicious googling seemed to result in the appropriate behavior. but i’m
not entirely sure that i have the right switches in place. in the interests of
saving someone else this hass. the following worked for me.
% sudo xcode-select -switch \
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer
note, that one would expect the following to work as well, but interestingly some stuff tries to sniff even further into the directory hierarchy and points at a number of 10.7 specific SDKs. these are not picked up by the CLI tools.
% sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
i suspect there’s deeper magic i need to divine in order to make sure that i really haven’t screwed something up here. but at least my stuff is building complaint/warning free.
