Qt-5.4.0 undefined reference to `QDebug::~QDebug()'

sboyce

A previous git clone of qt-5.4.0 does not report this error when building my application.
The clone dated 29th. June is OK but the ones done in the last few days give the error.

This is something for IRC, development mailing list, or the bug tracker. Qt developers are rare on this forum and your post is very likely to go unnoticed.

Hi,

Qt 5.4.0 is not yet released. You have cloned the "dev" branch, which is expected to be unstable.

For your project, using an officially-released version is recommended. You should clone the "v5.3.1" tag instead.

Thanks,
Where I have come across the problem I reverted to 5.3.1.
git clone now gets 5.3.1 and I checked out dev to get 5.4.0.

git branch

5.3

dev

_dmp

I got http://download.qt-project.org/development_releases/qt/5.4/5.4.0-beta/single/qt-everywhere-opensource-src-5.4.0-beta.tar.xz

When I compile I got errors:

.obj/qsqldatabase.o:qsqldatabase.cpp:function QSqlDatabasePrivate::database(QString const&, bool): error: undefined reference to 'QDebug::~QDebug()'

.obj/qsqlfield.o:qsqlfield.cpp:function operator<<(QDebug, QSqlField const&): error: undefined reference to 'QDebug::~QDebug()'

.obj/qtestlog.o:qtestlog.cpp:function QTest::messageHandler(QtMsgType, QMessageLogContext const&, QString const&): error: undefined reference to 'qFormatLogMessage(QtMsgType, QMessageLogContext const&, QString const&)'

.obj/qnetworkaccessbackend.o:qnetworkaccessbackend.cpp:function QNetworkAccessBackend::createUploadByteDevice(): error: undefined reference to 'QNonContiguousByteDeviceFactory::createShared(QSharedPointer<QRingBuffer>)'

what can help me?

Some body get compiled Qt 5.4 beta for imx.6 successfully?
