Which BSD is Mac OS X based on

[jaboua]

Most, if not all current OS X applications are written with Carbon, or Coacoa (both proprietary Apple toolkits) and would have to be rewritten to be ported to any other operating system.

Unless... Another OSS backend for carbon/coacoa is created, and macosx apps with tiny efforts can be compiled on other *NIX?

Once again, how would developers do that? The code to Carbon/Coacoa is proprietary, I would imagine it would be illegal, and the code to all those apps is proprietary so it could never be OSS. Prehaps someday, "Warez Culture" Hackers might do something like that, which would be awesome.

What about OpenOffice.org http://porting.openoffice.org/mac/

And http://www.gnustep.org/ which is opensource and compatible with Cocoa

[Demetrius]

Apple makes it fairly easy to port native unix and X11 applications into OS X by providing tools to integrate the features allowed by Coacoa and Carbon into the existing code. They dont make it easy, however, to port native OS X applications out of OS X to other operating systems.

But it still can be done

It can be done but it requires alot of effort, so I doubt anyone would bother with it.

What about OpenOffice.org http://porting.openoffice.org/mac/

OO.o is based highly on Java iirc (though it's core is C++ iirc), and since java is platform independant, you can write in in windows, and it would still work on mac or linux.

Also isn't there an openoffice without java

OpenOffice works fine without java, however it will remain "crippled" with some functions unavailable.

As dylunio said, the core is c++:

Written in C++ and with documented APIs licensed under the LGPL open-source license, OpenOffice.org allows any knowledgeable developer to benefit from the source. And, because the file format for OpenOffice.org is XML, interoperability is easy, making future development and adoption more certain.
