I downloaded a pre-compiled qt5-webengine from https://sourceforge.net/projects/fabiololix-os-archive/files/Packages/ And then "sudo pacman -U qt5-webengine-5.15.19-4-x86_64.pkg.tar.zst"

Then the notepadqq did compile without errors.

tried to rebuild qt5-webengine (see patch in qt5-webengine too: https:// vs git://), but notepadqq has then (with libicu 78) segmentation fault

Aborting... -> error making: notepadqq-exit status 4 -> Failed to install the following packages. Manual intervention is required: notepadqq - exit status 4

So it will not compile... (all other my other software is pacman up-to-date).

Maybe it's an icu/libicui18n version problem as the icu package was recently updated from v76 to v78.
