hi Friedemann,
Thanks for the information,
adding
QT += axcontainer to my .pro solved the issue and I can use the ActiveQt
interfaces for Example: SetControl without any issues.
I was just wondering, if above trick solves the problem, then
why Qt documentation suggests to build ActiveQt static libraries manually?
Thanks for your help...
Warm Regards,
Mahesh Kammar

Subject: Need help in generating ActiveQt Libraries...
Hi All,
I am new to Qt, am trying to use SetControl of QAxWidget class to host some Wpf
control in Qt which is exported as COM.
I am getting the following linking error, understand that I need to provide
ActiveQt library, but am not able to generate one I do not find QAxBase.lib
file or any other ActiveQt libraries.
I really don't know how to change this QTDIR path to generate ActiveQt
libraries, please help. It is not clear to me what to do when I refer it in
http://doc.qt.io/qt-5/activeqt-index.html#activeqt-framework
mainwindow.obj:-1: error: LNK2019: unresolved external symbol public: bool
__thiscall QAxBase::setControl(class QString const )
(?setControl@QAxBase@@QAE_NABVQString@@@Z) referenced in function private:
void __thiscall MainWindow::on_pushButton_clicked(void)
(?on_pushButton_clicked@MainWindow@@AAEXXZ)
mainwindow.obj:-1: error: LNK2019: unresolved external symbol public:

MainWindow::on_pushButton_clicked(void)
(?on_pushButton_clicked@MainWindow@@AAEXXZ)
debug\QtWinApp32bit.exe:-1: error: LNK1120: 2 unresolved externals
Here is my simple code:
QAxWidget *axObj = new QAxWidget(0,0);
axObj-setControl(QString::fromUtf8({BF71CE63-0A2E-419D-B7DE-41BE2CE6}));
Thanks in Advance
