After installing XCode7.1, the solution of various problems QT5.5 appears

After installing the XCode7.1, I suddenly found that QT5.5 could not compile the program. Directly in the terminal input clang, unexpectedly output the following information.

Agreeing to the Xcode/ios license requires admin privileges, please re-run as root via sudo.

In fact this is the need for us to agree with a license. Enter the following command in the terminal.

sudo xcodebuild-license

will open a protocol, press SPACEBAR to browse to the last, then enter agree. So clang can.

However, the following error will still occur when compiling the project with QT5.5.

' cstddef ' File not found

This is due to the use of a low SDK version, only need to add the following configuration in the pro file to use macosx10.11

QMAKE_MAC_SDK = macosx10.11
