Compilation error on Ubuntu 20.04

[Vivien-lelouette]

Hello,

I am currently trying out Nyxt. I find it pretty cool, but I would like to try using webengine instead of webkit.

To do so, I am trying to compile this project on Ubuntu 20.04, with the following qt dependancies installed: sudo apt install libqt5core5a libqt5gui5 libqt5widgets5 libqt5webenginewidgets5

I get the following stacktrace:
~/common-lisp/cl-webengine master 18:56:46❯ sudo make all

As I am not yet confortable with common lisp, I am not able to understand if I am doing something wrong, or if there is a bug in this project compilation.

Can you advise me on the matter ?

Hi, the cl-webengine project is still at its infancy and might not build properly at the moment. Hopefully we can dedicate more time to it at some point, but in the meantime I'm afraid it won't be usable. Contributions are welcome of course! Note: As a rule of thumb, never use "sudo" when building software locally, it's dangerous ;)

hi,

according to https://doc.qt.io/qt-5/qwebenginepage.html#lifecycleState-prop

setLifecycleState() was introduced in Qt 5.14.

Good point, thanks for the link!
