Unable to compile when using QtDeclarative

If I make an instance of QDeclarativeView my code is unable to compile and I get the following errors.

@c:\Qt\qt-everywhere-opensource-src-4.7.0-rc1\lib/libQtDeclarative.a(qdeclarativevaluetype.o):qdeclarativevaluetype.cpp:(.text+0x4c8): undefined reference to `_imp___Z13qt_defaultDpiv'

c:\Qt\qt-everywhere-opensource-src-4.7.0-rc1\lib/libQtDeclarative.a(qdeclarativevaluetype.o):qdeclarativevaluetype.cpp:(.text+0x552): undefined reference to `_imp___Z13qt_defaultDpiv'

collect2: ld returned 1 exit status@

Source:

@#include <QApplication>
#include <QtDeclarative/QDeclarativeView>

int main(int argc, char * argv[])
{
QApplication app(argc, argv);
QDeclarativeView view;

return app.exec();
}
@

Qmake project file

@QT += declarative gui
TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .

Input

SOURCES += main.cc@

Does anyone have an idea what might be wrong? By the way I compiled qt statically if this has any impact.

Hi

Wich Qt version and compilator you use?

Version 4.7.0-rc1 and mingw (gcc 4.4.1-tdm-2)

What is the demangled symbol name that is missing? Run @c++filt _imp___Z13qt_defaultDpiv@ to find out:-)

I just get the same string back.

This should now be fixed in the qt-qml staging branch (commit 0537750396ea519bbdf2b0fed086d535fc8c53b7).

Thanks, this solved the issue. I ran into 1 or 2 similar errors while building other modules and used the same fix to solve it.

Great! Any chance you can raise a bug in the "tracker":http://bugreports.qt.nokia.com detailing what else needs to be fixed to compile correctly?

Thanks,
Michael

There were already a couple of issues but none of them had fixed for all the issues so I created a new one.

Hmmm..... I'm having a similar issue using QT 4.7.0 with GCC 4.4.0, so I guess this wasn't fixed in the final release after all :(

After compiling statically (configure -static -release) I get the following error when issuing mingw32-make:

Any advice?

Perhaps it wasn't included in the release. If you get the tar ball from gitorious it probably works. "http://qt.gitorious.org/qt/qt/archive-tarball/4.7":http://qt.gitorious.org/qt/qt/archive-tarball/4.7
