Darwin Team Answers & Develop on Darwin
Lagos writes "In July Darwin developers at Apple had a call for questions. Their answers were posted on Monday and may be found here. There is some discussion of Apple's place within the Open Source community, though most of the questions answered are more technical." Along the same Darwinian lines, this submission came in: Maktoo writes "Maccentral is reporting that SourceForge.net has added PowerMac G4 Servers running MacOS X 10.1 into their Compile Farm. Now any apps you have going on SourceForge, you can test to see if it'll run on OS X! Gotta love that BSD heritage... OS X is already going to benefit greatly from all the apps it can use in the UNIX/Linux space. This just makes life easier for developers to bring even more."
If you interested in getting more OS X information in general, the Collge Park chapter of ACM is having a speaker from Apple today to talk about it. Its from 5-6, in the Classrom Building (yes, that actually is the name of one of our buildings), room 0111

the simple answer: Sort of.
the real answer: it all depends...
the explanation: if you can compile it, you can run it. if its a command line program, you're porting compile is considerably easier. if its Graphical, you've got a bit harder approach since OSX uses Aqua - a graphical display system which has bases in display PDF (some *nixes GUI systems used to be based on Display Postscript - see Solaris' OpenWindows v1.x)
however, since i've yet to see a linux/bsd / solaris / aix application that uses aqua, if its a gui program its probably doing Xwindows. to run X on X, you gotta do some tricks, theres a few methods, but Darwin has ported XFree86 to X. it runs pretty well too.
what i've found is that the quickest way to get an aqua app running is to find a java version of the application if possible since the awt/swing -> aqua stuff is abstracted by the osx implementation of java. but this doesnt solve all your woes.
The short answer is yes: OS X is a Unix variant - so you only need to recompile the software. In fact many tools of OS X are typical Unix programs, apache, perl, gcc, tcsh, etc...
The long answer is, it depends. While OS X is clearly Unix, there are some issues:
- OS X is from the BDS Unix familly, so linux programs might need some tweaking.
- OS X is structured differently from other Unixes, standart paths are different and configuration files are very different.
- Most Unix system use the X11 standart for GUI. OS X does not use X11 but instead a protocol based on display PDF. While it is possible to install an X11 server (for instance Xfree), this is not the default installation.
Still many Unix programs have been ported to OS X in the rather short timeframe of it's existence(~six months).Many people complain about Linux not being user-friendly enough in the GUI. Whether that is true or not is irrevelant to my question. Near everyone can agree that Apple has the best GUI. We're talking about how easy it is to port *BSD/Linux apps to OS X ... how easy do you think it would be for Apple to port Aqua to *BSD/Linux?
-As beautiful as KDE is, I would drop it in a heartbeat for Aqua.
