In Devuan Ceres, starting in 2021-08 with libglib2.0-0=2.68.3-2 the file icon_loader.cpp fails to compile. By removing the static_cast, this file can compile. The built application throws all sorts of GLib-GObject-CRITICIAL messages but the application operates.
Downgrade to "deb [check-valid-until=no] https://snapshot.debian.org/archive/debian/20210801T144205Z/ unstable main non-free contrib" in /etc/apt/sources.list and install the exact libglib version necessary to compile without this patch.
$ sudo apt-get -V install libglib2.0-0=2.66.8-1 libglib2.0-bin=2.66.8-1 libglib2.0-data=2.66.8-1 libglib2.0-dev=2.66.8-1 libglib2.0-dev-bin=2.66.8-1 libglib2.0-0:i386=2.66.8-1
Zenju tried addressing this for me, but it still does not compile, even with g++-12. So I still have to omit this macro call.
