OSX clang 64-bit release kit - qmake always generates "this project is using private headers"

VRHans

I've been having some odd issues on OSX and trying to track them down, and I just noticed that when I run qmake I get the following warnings:

11:41:52: Running steps for project testApp...
11:41:52: Starting: "/Users/hans/Qt5.7.0/5.7/clang_64/bin/qmake" /Users/hans/Desktop/testApp/testApp/testApp.pro -r -spec macx-clang CONFIG+=x86_64 CONFIG+=qtquickcompiler
Project MESSAGE: This project is using private headers and will therefore be tied to this specific Qt module build version.
Project MESSAGE: Running this project against other versions of the Qt modules may crash at any arbitrary point.
Project MESSAGE: This is not a bug, but a result of using Qt internals. You have been warned!
11:41:52: The process "/Users/hans/Qt5.7.0/5.7/clang_64/bin/qmake" exited normally.
11:41:52: Elapsed time: 00:00.

I do not get these warnings with my debug qmake call. I have never added anything related to private headers, and I even went through and make sure I used <QQuickItem> style of includes instead of <qquickitem.h> everywhere in that was the issue.

There's nothing in my .pro that includes or mentions anything private, so I am a loss as to know why this message keeps coming up?

Here's my .pro

TEMPLATE = app

QT += qml quick

# Windows, OSX, and linux use webengine
win32 | macx | unix {
	QT += webengine
}

CONFIG += c++11

SOURCES += main.cpp \
        IMLogger.cpp \
        IMManager.cpp \
        IMOptions.cpp \
        plugins/FalsePlugin_Debug/FalsePlugin_Debug.cpp \
        plugins/FalsePlugin_Diagnostics/FalsePlugin_Diagnostics.cpp \
        plugins/FalsePlugin_Enrollment/FalsePlugin_Enrollment.cpp \
        plugins/FalsePlugin_Profiles/FalsePlugin_Profiles.cpp \
        IMCmdLineParser.cpp

HEADERS +=  \
        IMLogger.h \
        IMManager.h \

        plugins/FalsePlugin_Enrollment/FalsePlugin_Enrollment.h \
        plugins/FalsePlugin_Profiles/FalsePlugin_Profiles.h \

RESOURCES += qml.qrc

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# The application version
VERSION = 0.1

# Define the preprocessor macro to get the application version in our application.
DEFINES += APP_VERSION=\\\"$$VERSION\\\"

I google for this but couldn't see any reason why this would be affecting me...

BTW - I get the same warnings if I build release versions of the example Qt applications that shipped with Qt 5.7.

Thanks :)

Hi,

What if you remove the qtquickcompiler from CONFIG ?

VRHans

That makes those warning disappear.

Does that indicate a bug in Qt or some bad in my Qml?

SGaist

Neither, it's a known limitation explained here.
