I see, that indeed appears to work on fedora, but not on the nixos box I tested (because having different include paths made testing easier there, but now I'm testing on fedora it looks OK there as you say) The difference between the two is that nixos is using the freedesktop pkg-config[1] while fedora uses pkgconf[2], so it would appear this isn't standard maybe? At which point the man page could use being more explicit about it... Oh, now I'm looking there's a (rather long) bug open about this here: https://bugs.freedesktop.org/show_bug.cgi?id=105572 [1] https://www.freedesktop.org/wiki/Software/pkg-config/ [2] https://github.com/pkgconf/pkgconf > I've patched many packages to use that feature, and haven't noticed any > breakage (so far). Well, packages can be fixed on the fedora side, but as upstream I wouldn't accept such a change until the freedesktop version behaves the same as I'd want to support users of either pkg-config version.

Yeah, complex frameworks are difficult with that, but upstream is actually dealing with it indirectly by switching to more modern build systems (for gtk, see gnome's MesonPorting[3] page) meson will automatically add --as-needed to the linker flags as appropriate (don't ask me what is appropriate), so we won't need to force it for them when they're done. Eventually some autotools/libtool macro could be added for other projects to use..
