[Interest] FW: Need help in generating ActiveQt Libraries...

[Kammar, Mahesh]

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 at QAxBase@@QAE_NABVQString@@@Z) referenced in function "private: void __thiscall MainWindow::on_pushButton_clicked(void)" (?on_pushButton_clicked at MainWindow@@AAEXXZ)
mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: __thiscall QAxWidget::QAxWidget(struct IUnknown *,class QWidget *,class QFlags<enum Qt::WindowType>)" (??0QAxWidget@@QAE at PAUIUnknown@@PAVQWidget@@V?$QFlags at W4WindowType@Qt@@@@@Z) referenced in function "private: void __thiscall MainWindow::on_pushButton_clicked(void)" (?on_pushButton_clicked at 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-BBBB41BE2CE6}"));



Thanks in Advance....

Warm Regards,
