Qt5 Target conditionals not found

Question

I just updated to the latest version of command line tools in OS X Mavericks and now when compiling my (previously-working) code it throws the following error

> clang: warning: no such sysroot directory:

Does anyone knows that if changing this line

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk

from sdk 8 to 9 would work? If so, where in the parameters of Qt5 can I change this?

Answer 1

For other people's reference, I solved the issue by editing my platform mkspec file:

/users/nic/Qt/5.3/clang_64/mkspecs/qdevice.pri

change the following line:

!host_build:QMAKE_MAC_SDK = macosx10.8

to this:

!host_build:QMAKE_MAC_SDK = macosx10.9

Be sure to clean your project and run qmake again.

Answer 2

It is possible to compile the project also by adding the following line to the .pro file

QMAKE_MAC_SDK = macosx10.9

Answer 3

If you compile in other platforms than OS X, an improvement of BRabbit27 solution would be:

macx {
QMAKE_MAC_SDK = macosx10.9
}

Answer 4

I just upgraded to XCode 9 and I started getting this problem on macOS Sierra (10.12). The problem is that Xcode moved the default symlink to 10.13. To fix:

cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
sudo ln -s MacOSX.sdk MacOSX10.12.sdk
