Cannot find TargetConditionals.h

TheFlyingMooseMan

After months and months of working with QT Creator, compiling that has been compiling fine for months, yields in the following error message...:

/Volumes/Home/roy/Qt5.7.0/5.7/clang_64/lib/QtCore.framework/Headers/qsystemdetection.h:95: error: 'TargetConditionals.h' file not found
#  include <TargetConditionals.h>

What is the next step to solve this?

Thanks for any pointers/hints,
Roy

Hi,

Any chance of Xcode upgrade recently ?

TheFlyingMooseMan

@SGaist It looks like there was an upgrade. All of a sudden I had to run make as root and had to answer some questions. What should be done next?

SGaist

Do a full clean rebuild.

If that's still not good, you may have to force the macosxsdk to 10.12.

TheFlyingMooseMan

@SGaist That did not work. How do I force macosxsdk to 10.12?

SGaist

Add

macx {
    QMAKE_MAC_SDK = macosx10.12
}

to your .pro file.

TheFlyingMooseMan

@SGaist And that did work. Thanks a lot!

SGaist

You're welcome !

You shouldn't need it anymore after the next Qt update.
