Re: OSX and XQuartz support

Hi Rafal, 
I’m not a windowing systems expert but for all intents and purposes XQuartz is X11 for OSX, it literally gives OSX an X11 backend option. See https://www.xquartz.org/. As for the details of the project that use the windowing system, I’m uncertain and it would take some effort to figure out what breaks if I tried to switch to a Quartz backend. So asked another way, what are the jhbuild commands to build GTK on a linux/unix system? 

Cheers, 

Andrew

 Hi Paul, 

 Thanks for the clarification. Your point about using the native Quartz
windowing system is well taken and may be implemented in the future but right
now thats a bit of a distraction for me. The code I want to compile is
actually sitting in the source that jhbuild pulls down, namely
~/gtk/source/gtk+-2.24.31/gdk/x11 and I have XQuartz installed on my machine
so I have the necessary X11 dependencies but I’m not fluent enough in the gtk
dependency scheme to understand how modify the makefiles to build gtk against
x11 on a mac.  

I'm not sure if I understand your issue correctly so I provide multiple
answers in hope that at least one of them is correct. X11 is a default
GTK backend for Linux and several other Unix-like operating systems.
For OS X the default backend is Quartz. X11 is not available (although
I'm not sure how XQuartz works). I don't know what your application
does. If it uses only the portable GTK and GDK API you should just
build GTK against Quartz (which is default) and your application
should work without any problem. Do you use any X Window System
Interaction API [1] or X API (like Xlib [2]) directly? They will not work
(again, I'm not sure about it and I'll appreciate if somebody explains).
If possible, please remove those calls from your code. You can use
conditional preprocessor directives (#ifdef ... #else ... #endif).

Hope that helps. Regards,

Rafal
