Re: [gtk-osx-users] GTK with Quartz backend

[Gabriele Greco <gabrielegreco gmail com>]

I read in a mailing list (not the one of osxcross) that some do not use
Apple hardware as an European court would consider it a vexatious
clause, and therefore that software related clause should only be
applied in the USA.
Anyway should be always possible legally cross-compile from Linux on
Apple HW.

The gtk-osx-build system itself require macOS to work, but nothing prevents you from building it on a Mac, then move the whole tree it created (that with jhbuild you can place for instance in /usr/local/gtkosx ) to another machine, also linux, provided you use a similar build system and deployment target, AFAIK osxcross supports libc++, so it should be possible.

You will be able to build macOS binaries that use the GTK quartz backend, probably you will need to do some changes to the scripts if you want to use also the gtk-mac-bundler to build an app bundle with the gtk libraries inside since it depends from command line utils that usually have different names in not macOS targets.

Anyway since virtualizing macOS is forbidden on non macOS hosts, building macOS software with CI services (like github actions, travis...) is very expensive, amazon just introduced an AWS mac mini, but it's more expensive that an AI instance with a TESLA cad.... I'm not really sure that cross compiling to mac is a bad thing... also because you are not using the software itself, but just some supporting files (header and libraries) that you are allowed to use as developer.
