XCode 4.3 changed location of compilers

[snaury@…]

Uninstalled XCode 4.2, installed XCode 4.3. Now anything that depends on C compiler fails to build, because path to clang is used as $DEVELOPER/usr/bin/clang, which is wrong for 4.3. For example:

$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
$ sudo port -v install graphviz
[...]
checking for gcc... /Applications/Xcode.app/Contents/Developer/usr/bin/clang
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.
[...]
$ sudo port -v install mercurial
[...]
building 'mercurial.base85' extension
/Applications/Xcode.app/Contents/Developer/usr/bin/clang [...]
unable to execute /Applications/Xcode.app/Contents/Developer/usr/bin/clang: No such file or directory
[...]
$ xcrun -find clang
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang

If I use xcode-select to switch to / then xcodebuild -version calls take forever because they scan my whole hard-drive, so currently there's no xcode-select -switch path that would work for all needed tools.

Perhaps macports should use xcrun -find to find actual locations of executables.

P.S. I know XCode 4.3 was just released, I'm logging it in case it's useful.

We are of course aware of this; see several other tickets and extensive discussion on the mailing list today. MacPorts base in trunk already uses xcrun; we have not yet released a version of MacPorts incorporating this change, so until we do, feel free to build MacPorts from trunk, or to go back to Xcode 4.2 with which MacPorts 2.0.3 works fine.
