Linked thread: https://stackoverflow.com/questions/73005956/qt5-error-class-qtextbrowser-has-no-member-named-setmarkdown.

I'm going to investigate tonight.

Yes. It would be of great help. Looking forward to trying your tool. If you want can connect on a meeting too.

I can confirm that the setMarkdown function was introduced in Qt 5.14.0. Regarding that, I think your Qt's installation is broken, since I just tested on a 5.14 install. One reason could be that you are using sudo to build Degate, and maybe it uses another version of Qt. Since the issue is surely coming from your installation, I cannot help you more. One solution could be to install the latest Qt5 version (5.15.5), an LTS, from the Qt installer (official): https://www.qt.io/download-open-source#section-2. Also, please read carefully the Degate's build instructions from the readme (available here: https://github.com/DegateCommunity/Degate#for-linux-debian-like).

If nothing work, you will need to provide more information:

• The result of sudo qmake -v,
• Full build logs,
• Which branch you are trying to build (master or develop),
• Your full OS version,
• The result of uname -a.

Finally, if you just want to try Degate, you can find prebuilt binaries here: https://github.com/DegateCommunity/Degate/releases/tag/v2.0.0 (latest release). If, like me, you are wondering about possible security issues regarding these prebuilt binaries, please check our security notice here: https://github.com/DegateCommunity/Degate/blob/develop/DOWNLOADS_SECURITY.md.

If you need anything else, don't hesitate :)
