Unsolved How to build Qt with designer support using Qt Online Installer for Linux (64-bit)?

[satishkumarc]

Hi all,

I have attempted to install QT 5.9.1 on my Ubuntu 20.04 using the Qt Online Installer for Linux (64-bit) that I found here. While building an application that requires me to have QT 5.9.1 (with designer support) as a dependency, I encountered the following error:

Project WARNING: QwtDesigner is enabled in qwtconfig.pri, but Qt has not been built with designer support

Could someone please let me know what options must I choose in the GUI that opens when I run the "Qt Online Installer for Linux (64-bit)" in order to install QT with designer support on my Ubuntu 20.04 machine? What I have chosen is a 'Custom Installation' in the QT Setup page and then selected 'Qt 5.9.1' under 'Qt' in the 'Select Components' page. What else must I choose to have the designer support? Any response will be very much appreciated.

Thanks in advance,
Satish
