#40619: virtualbox @4.2.16 Wrong SDK Selected
---------------------------+--------------------------------

     Type:  defect         |     Status:  new
 Priority:  Normal         |  Milestone:
Component:  ports          |    Version:  2.2.0
 Keywords:  Xcode5         |       Port:  virtualbox
---------------------------+--------------------------------
 After recently upgrading to Xcode 5, VirtualBox will not compile.  At
 first glance, the error is identical to that posted in #35808.  After
 reading the comments and investigating the configure log, the command that
 fails is (full log attached)
 {{{
 /opt/local/bin/g++-apple-4.2 -mmacosx-version-min=10.7 -isysroot
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk
 -Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk

 error: cstdio: No such file or directory
 }}}

 Digging around, it turns out that the 10.7 SDK has been removed from of
 Xcode 5 and 10.8 is now included.

 Reading ticket:35808#comment9 lead me to the configure script where there
 is a 'To Do' note to use Xcode/SDK version to get the version number.
 Playing around a bit, I was able to establish the following code snippet
 to extract the SDK name and version number
 {{{
 $ sdkname=`xcodebuild -showsdks | grep macosx | awk '{print $NF}'`
 $ echo $sdkname
 macosx10.8
 $ xcodebuild -version -sdk ${sdkname} SDKVersion
 10.8
 }}}
 I would offer an explicit patch, but I'm exactly sure where this would
 need to go, and I don't know how it would effect those who haven't
 upgraded Xcode yet.  I also do not know how wide spread the issue of the
 missing SDK will be.
