Hello, I am one of the upstream maintainers of pyfltk https://pyfltk.sourceforge.io/ I adopted the orphaned python-pyfltk package in the AUR. In the process of creating a PKGBUILD, I noticed that the FLTK 1.4.4 package in the extra repo is not built with Wayland support. One of the main new features of FLTK 1.4 is that it now has native Wayland support. Hence, pyfltk 1.4 now also has native Wayland support. I would like to request that FLTK be re-built with Wayland support. Here are some of the missing makedepends packages cairo pango libdecor wayland-protocols There may be more packages required. You can verify that wayland is supported from the output of the cmake command. The README.Wayland.txt in the FLTK source tree describes the dependencies for other distros like Debian and Fedora.
