Qt 6

@Rich-v

Closing this. Qt support confirmed they do not support windows hosts building 6.2 for QNX.

Hi,

The QtScript module has been deprecated and obsoleted during the Qt 5 series and AFAIK, it won't be ported to Qt 6.

Try porting to Qt 5.15 first, it should print you some nice deprecation and porting messages during compilation and at runtime. This will help you fix the issues.

A wild guess in this case: Qt 6 requires Q_PROPERTY types to be fully qualified (not forward declared). Go through your properties and make sure it's true.

This works! Thank you!

@Christian-Ehrlicher

@sierdzio you are right. Thank you very much! I placed Qt_Static back and it works now:

Static Release was created and It works:

Adding this bug report to the conversation: https://bugreports.qt.io/browse/QTBUG-88645

It appears GraphicalEffects is intended to be replaced by something like MultiEffect - which isn't ready for Qt 6 yet.

Solved.. The build and install directory should be different.

So, I've kind of solved that, I've updated to the latest VS, installed last available WinSDK (there were build errors with old ones), just comment out the check in the qglobal.h

//static_assert(!std::is_convertible_v<std::nullptr_t, bool>, // "On MSVC you must pass the /permissive- option to the compiler.");

After all I needed to disable building of qttools, there were other errors. That's not the perfect solution but at least I built it. And still I want to know why it does not build as explained in the documentation and having now LTS release 6.2.

@debian said in ld: cannot find atomic:

Problem in incorrect addititonal library name, LIBS contain correct -latomic and incorrect atomic.

Sorry missed that. No idea on the question. The qmake feature appears to be incorrect in some way, but I have no clue why.

Thanks, I solved ! Such as follows;

template <
typename _MyClass2>
MyClass1::MyClass1(
MyClass2 MyObject // !!! DO NOT USE QObject !!!
QObject* ChParent /= Q_NULLPTR/)
: QQmlPropertyMap(
MyObject,
ChParent)

Resolved.

Default Profile
The default profile is now off the record.
To have a standard browser profile with disk-cache and cookies, we recommend creating your own profile and using that explicitly.

So, I used m_webview->setPage(new QWebEnginePage(new QWebEngineProfile("MyProfile"))); instead of QWebEngineProfile::defaultProfile()->setPersistentCookiesPolicy(QWebEngineProfile::ForcePersistentCookies);, and it worked.
