Qt Creator : Failed build after update to xcode 9 GM

[jaden]

Hi.

Today, I installed xcode 9 GM seed. But Qt project build failed.

First error message... not found Mac sdk path

So, I modify a code of 'Qt5.9.1/5.9.1/clang_64/mkspecs/features/mac/sdk.prf file.

QMAKE_MAC_SDK_PATH = $$ system ( "xcodebuild -version -sdk | grep '^ Path * MacOSX'| cut -d ''-f 2")

After the change, the following error appears when building.

warning: no such sysroot directory: '-mmacosx-version-min=10.10' [-Wmissing-sysroot]

/Users/kakao/Qt5.9.1/5.9.1/clang_64/lib/QtCore.framework/Headers/qsystemdetection.h:95: error: 'TargetConditionals.h' file not found
 include <TargetConditionals.h>
           ^~~~~~~~~~~~~~~~~~~~~~

.... What should i am? ㅠ_ㅠ

Hi i am sure if you install the MacOSX-SDKs
from your version the problem is solved

CarbonHeaders TargetConditionals.h

Thank you for kind your answer. : )

I downloaded MacOSX10.12.sdk.

unzip file...
but how to install the sdk? ㅠ_ㅠ

It's installed means that the 10.12.sdk folder copy to '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs' path?

How to install the sdk? ...

[patrik08]

macOS Sierra?
is the Sierra not to slow? i wait to update wen become more stable point...
sdk is only copy at the right place inside Xcode or like https://stackoverflow.com/questions/34876144/where-to-download-an-slightly-older-ios-sdk

Yes, Sierra.
The sierra is more stable than I thought. : )

example of code you must insert in your .pro, replace 10.13 by whatever version you want...

macx {
   QMAKE_MAC_SDK = macosx10.13
   QMAKE_MAC_SDK_PATH = "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk"
}
