Good news.

...

Only the command line GNU tools in Xcode are open source, such as gcc itself.

Not all tools are open source (yet?) either, Xcode 2.4.1 and Xcode 3.0 have so far not been released.

I hope that is not really the case, as the GNU tools (not the BSD ones) such as gcc itself, are covered by GPL or LGPL copyleft rules. Unlike the source for the Darwin kernel, Apple are not allowed to be 6 months late with the source. Apple keep a public CVS for copylefted software.

And you'll need something like "odcctools", in order to actually build and use them outside of the Apple toolchain... http://www.opensource.apple.com/darwinsource/ and http://macosforge.org/

Perhaps some of the tools are not copylefted, and so leave gaps in the toolchain. Good luck to whoever tries to build all this then. (It won't be me!)

Objective-C++ eventually got included, so Objective-C 2.0 probably will. Someone needs to write a new runtime, though, such as the GNUstep one ?

Omitting the runtime source seems to sail close to the wind on copyleft. Does the gnustep runtime support Tiger?
