My build environment was using gcc-9, which does support the -std=c++2a. I build packages of FreeFileSync for other distros as well, and I know how to patch the program to compile it for -std=c++17 for gcc-8 or lower.

About the error in my OP, I used to get that exact error when building by hand on my dev box when I had gtk3 and gtk2 installed on Fedora; that's why I know this exact error about the "error: conflicting declaration ‘typedef struct _GdkDrawable GdkWindow’".

If you clear that gtk2//3 hurdle, here's another

g++ -std=c++2a

which version of gcc is installed? (the installed version may not be able to handle c++2a)

With https://salsa.debian.org/freewx-team/wx now producing files for GTK3 only, I am unable to resolve

nothing provides wx3.0-headers = 3.0.4+dfsg-14 needed by libwxgtk3.0-dev
nothing provides libwxbase3.0-dev = 3.0.4+dfsg-14 needed by libwxgtk3.0-dev

The package libwxgtk3.0-dev is no longer produced, because it is now only producing libwxgtk3.0-gtk3-dev. When I install libwxgtk3.0-gtk3-dev and try to compile my dpkg (FreeFileSync) I get this classic error:

This is a conflict when both gtk2 dev and gtk3 dev packages exist. I am only referencing gtk+-2.0 linking directories, so how is it getting the gtk3 parts? Or how can I get a current gtk2 package on my Devuan box?

I am also investigating compiling the application with gtk3 but that is considered experimental by the app upstream team.
