For SDK path detection wouldn't it be possible to use the xcode-select

Something like this in the configure.ac file should do the trick,
It won't do the trick of making macosx-setup.sh work, as that must be run before you can, on newer versions of OS X, even *generate* the configure script from configure.ac, much less *run* the configure script. Anders was having a problem with macosx-setup.sh building Qt.
So something needs to be done in macosx-setup.sh.
even if you are using a " beta " version of Xcode.
SDKPATH=`xcode-select - -p`/Platforms/MacOSX.platform/Developer/SDKs/"MacOSX$deploy_target.sdk"
The "-p" flag is a later addition - Xcode 3 didn't have it:
snowleopard.local$ xcodebuild -version
Xcode 3.2.6
Component versions: DevToolsCore-1809.0; DevToolsSupport-1806.0
BuildVersion: 10M2518
snowleopard.local$ xcode-select -p
Usage: xcode-select -print-path
or: xcode-select -switch <xcode_folder_path>
or: xcode-select -version
Arguments:
-print-path Prints the path of the current Xcode folder
-switch <xcode_folder_path> Sets the path for the current Xcode folder
-version Prints xcode-select version information
so what should be used is --print-path, not -p - --print-path, with two leading "-"s, works in Xcode 3.2.6 (and -print-path, with only one leading -, works in Xcode 6.1.1, but I'm less tempted to assume that will continue to work in the future).
However, on Xcode 3.2.6 again:
snowleopard.local$ ls `xcode-select --print-path`/Platforms/MacOSX.platform/Developer/SDKs
ls: /Developer/Platforms/MacOSX.platform/Developer/SDKs: No such file or directory
so that's not enough:
snowleopard.local$ ls /Developer/SDKs
MacOSX10.5.sdk
MacOSX10.6.sdk
On Xcode 6.1.1 on Yosemite, we have:
yosemite.local$ xcrun --show-sdk-platform-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform
but on 3.2.6 on Snow Leopard:
snowleopard.local$ xcrun --show-sdk-platform-path
xcrun: error: unrecognized option: --show-sdk-platform-path
usage:
xcrun [-verbose] [-no-cache] [-kill-cache] [-sdk <sdkroot>] [-log] [-run] <utility> [utility argument(s) ...]
xcrun [-verbose] [-no-cache] [-kill-cache] [-sdk <sdkroot>] -find <utility> <tool> [tool arguments ...]
And, if we also want to support installing just the command-line tools, you also have to look in /Library/Developer/CommandLineTools/SDKs; however, I think Qt refuses to install if you don't have Xcode installed - the command-line tools aren't sufficient.
