OS X "Native" version of Ardour gets closer
We are getting closer and closer to being able to release a "native" OS X version of Ardour that will not require X11. There are still several substantive issues to be resolved, but a few bleeding edge users are currently evaluating the initial "All In One" package that includes JACK as well as Ardour (and will very soon include a set of recommended LADSPA plugins too). This has been made possible by the amazing work of the GTK-Quartz porting team, who managed to get GTK to run on a system that is really fundamentally different in several key ways from X11. Stay tuned for more news.
As a footnote, it was very frustrating to discover that the wonderful experience that OS X generally offers to end-users is not maintained for developers. Certainly not developers wishing to build packages of an application that uses a large set of inter-dependent 3rd party libraries. Although the final result is quite pleasant, the pain involved in doing the packaging was quite astounding. Apple made some odd choices about this all should work, and left developers like me to clean up after them.
