I looked in the usual places (/usr/lib/,/Developer/usr/lib/,/usr/local/lib), and it isn't there.
If it isn't installed, does anyone know where I can find instructions to install it?
Thanks!
I'm not sure if I should close this, but I found the answer I was looking for:
In OS X, with XCode 4 installed, libclang.dylib is at /Developer/usr/clang-ide/lib/libclang.dylib
With the latest (appstore) XCode 4.3.2, the location changed, it can now be found in
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/libclang.dylib
The /Developer
directory, among others, no longer exists by default. Everything is now packaged inside the XCode application, so that delta updates from the appstore work.
