Hi, I also have Sierra, but in my Qt 5.9.1 the compiler has the path: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++

Maybe try updating your Xcode to 8.3.3 (2 months old)?

Also, If you open a Terminal and type

clang++ -v

what does the InstalledDir say...

SGaist

Hi and welcome to devnet,

Did you start Xcode once ? Accept the license agreement ?

Yogikipl

hi, thanks for your reply
clang++ -v
output is:-
Apple LLVM version 8.1.0 (clang-802.0.42)
Target: x86_64-apple-darwin16.0.0
Thread model: posix
InstalledDir: /Applications/Xcode 8.3.2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

& we are already using Xcode for other applications, develop in IONIC

Hi, Qt expects the compiler to be installed in /Application/Xcode.app/... that's probably why you get the error. It might work pointing Qt to the correct directory, open a Terminal and type:

sudo xcode-select -s /Applications/Xcode\ 8.3.2.app/Contents/Developer

If that doesn't work, you could also try creating a symbolic link in /Applications named Xcode.app that points to Xcode\ 8.3.2.app...

@hskoglund Hi, thanks
xcode-select -p
already print
/Applications/Xcode 8.3.2.app/Contents/Developer

SGaist

Maybe you are hitting QTBUG-61690

Yogikipl

@SGaist Hi, QTBUG-61690 not having any solution.

jsulm

@Yogikipl Wrong. It is fixed in Qt 5.9.2

hskoglund

Hi (if you don't want to wait a couple of weeks for 5.9.2) you can apply the patch yourself, open $HOME/Qt/5.9.1/clang_64/mkspecs/features/toolchain.prf and change line 41 from

darwin: cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH

to

darwin: cxx_flags += -isysroot $$sdk_path_device.value

Yogikipl

Hi,

change:-
darwin: cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH

to

darwin: cxx_flags += -isysroot $$sdk_path_device.value

restart QT Creator, Same error

@Yogikipl
Hi, its not option just to use Qt 5.9.2 ?
BUG report says it fixed in that version.

hskoglund

@mrjj Release version of 5.9.2 is difficult to download right now, not available in MaintenanceTool yet.

@Yogikipl: I tested and could reproduce your bug, when trying to compile the example Qt Quick Controls 2 - Gallery on my Mac. First my fix above wasn't complete, you need the full change (same that's coming in 5.9.2), so change the line (same as before)
darwin: cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH
to these 5 lines:

darwin {
    uikit:macx-xcode: \
	    cxx_flags += -isysroot $$sdk_path_device.value
    else: \
	    cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH
}

Also it not sufficient just to restart Qt Creator. First, delete your .pro.user file, so you get to reselect the compiler(s) again. Then there's a problem with the caching of files, so try open and close the project a couple of times, to get the "green arrow" lit in Qt Creator and be able to compile.

mrjj

@hskoglund
Ok, so its a build yourself version still :)

hskoglund

@mrjj yeah, the wiki says "August 2017" for 5.9.2 so there's plenty of time left :-)

mrjj

@hskoglund
hehe and thats the "Original plan" so might go a bit over :)

Yogikipl

@hskoglund Hi, we try to replace with
darwin {
uikit:macx-xcode:
cxx_flags += -isysroot $$sdk_path_device.value
else:
cxx_flags += -isysroot $$QMAKE_MAC_SDK_PATH
}

& create a new project, & also restart several time, but still there is same error.

SGaist

What happens if you run /Applications/Xcode 8.3.2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ in a terminal window ?

hskoglund

@Yogikipl Did you forget the 2 backslashes? That might explain why you still get the error.

Yogikipl

@hskoglund no, back slash are there, as you provide
