Project ERROR: Cannot run compiler '/Applications/Xcode 8.3.2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++'. Maybe you forgot to setup the environment?

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

Yogikipl

@SGaist
when we run
/Applications/Xcode 8.3.2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++
output :-
clang: error: no input files

I has the same error with version 5.9.0 and 5.9.1 installed on Sierra.
I just installed 5.9.2 Snapshot using the Online installer (also work with the MaintenanceTool.app and the problem is now solved !

I Resolved the problem with Xcode 14.2 only by removing space from XCode path.

"Xcode 14.2" renamed to "Xcode-14.2".
