Windows

• The official libs are available from http://win32builder.gnome.org/
• We do not need all of them, the needed subset will be included in the dependency bundle (in buildwin/gtk)
• The headers are in our tree (https://github.com/nohal/OpenCPN/commit/9cf849d218cdf983b9eacd029090406dbc255469)
• Local build is a total alchemy. Do not even try...

OS X

• The instructions come from https://wiki.gnome.org/Projects/GTK+/OSX/Building
• Get https://git.gnome.org/browse/gtk-osx/plain/gtk-osx-build-setup.sh
• sh gtk-osx-build-setup.sh
• .local/bin/jhbuild bootstrap
  • There should be no need to set the SDK versions /actually when I tried to set everything to 10.7, the builds started to get broken/ as 10.7 is the newest jhbuild deployment target available
  • cmake failed, made it succeed by looking up the way it called ./bootstrap and then running it manually with added --system-curl parameter in another terminal, then repeated jhbuild build stage and everything completed fine
• .local/bin/jhbuild build meta-gtk-osx-bootstrap
• .local/bin/jhbuild build meta-gtk-osx-core
• .local/bin/jhbuild build librsvg
• The libs are now available in gtk/inst/lib
• Get the list of ones we need using otool -L gtk/inst/lib/librsvg-2.2/dylib
• Copy them to buildosx/gtk
• We use the local includes (same as on Windows)
• We can most likely provide the dylibs prebuilt to save people time and use consistent set of libraries
