Compiling error with wwWidtes.qt 4.6.2

[Andrewshkovskii]

Hello all!
i build wwwidgets like this :
qmake -spec win32-g++ -r CONFIG+=release,
Mingw32-make-install.
and now i got a problem with compiling simple project with wwWidgets :
.pro

TEMPLATE = app
SOURCES += main.cpp
CONFIG += wwwidgets

#include <QtGui/QApplication>
#include <QwwTwoColorIndicator>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QwwTwoColorIndicator id;
    id.show();
    return a.exec();
}

#include <QtGui/QApplication>
#include <QwwTwoColorIndicator>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QwwTwoColorIndicator id;
    id.show();
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

buildind in release. So, i got error message :

testWWW/../../Qt/include/wwWidgets/qwwtwocolorindicator.h:21: undefined reference to `QwwPrivatable::~QwwPrivatable()'

But QwwPrivatable is defined in #include <wwglobal.h> witch is including in all qww classes.
Why is happening and what i'am doing wrong?
Because every example coming with wwWidgets is compiling, cleaning and re-building and qmake'ing as well, as normal project.
