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 From: Kammar, Mahesh Sent: Friday, March 20, 2015 5:01 PM To: 'interest@qt-project.org' 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: __thiscall QAxWidget::QAxWidget(struct IUnknown *,class QWidget *,class QFlags<enum Qt::WindowType>)" (??0QAxWidget@@QAE@PAUIUnknown@@PAVQWidget@@V?$QFlags@W4WindowType@Qt@@@@@Z) referenced in function "private: void __thiscall 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-BBBB41BE2CE6}")); Thanks in Advance....
