> GTK2 development packages not found. If GTK2 packages are installed, please remove the build directory and try again.
So I tried to use a nix-shell environment to make sure gtk2 was available like so:
nix-shell -p binutils ant gnome2.gtk but when I tried to build the SDK again it still failed with the same error. I also tried using
gtk2-x11 instead, but that didn’t work either.
