compile error for ios from Qt but not with xcode

[SherifOmran]

I have an error when i compile a test application with a dummy button directly from QT with the auto detected ios sdk, and although the device is connected and correctly setup from the developer.apple website

03:20:57: Running steps for project testmobileapp...
03:20:57: Starting: "/usr/local/Qt-5.12.0/bin/qmake" /Users/sherifomran/Desktop/testmobileapp/testmobileapp.pro -spec macx-g++ CONFIG+=iphonesimulator CONFIG+=simulator CONFIG+=qtquickcompiler
Project ERROR: failed to parse default search paths from compiler output
03:20:57: The process "/usr/local/Qt-5.12.0/bin/qmake" exited with code 3.
Error while building/deploying project testmobileapp (kit: QT Kit IOS 5.12)
When executing step "qmake"

However, when i convert the code with qmake to xcode project, it works ! humm !
This is a test project with default project setting

any idea?

Hi,

How did you install Qt on your machine ?

[SherifOmran]

I compiled it from source code

Out of curiosity, why ?

And do you also have the same problem with the pre-built version ?
