Hi Ruben,

Thanks for your interest in the darwinx toolchain.

The toolchain as it is now works fine albeit with some small nitpicks.
The most important issues which still surround this toolchain are the
legal part and the fact that support for debug symbols in binaries is
broken due to the absence of the source code of the dsymutil tool.

I wasn't aware that the macports project is using gcc 4.6 for Mac OS X.
The main question I have with using gcc 4.6 is whether it works stable.
Apple decided to fork gcc 4.2 and heavily patch it for optimal support
for Mac OS X (this version can be found on the Apple website). Most of
those patches haven't been upstreamed AFAIK (as they're only useful for
Mac OS X) so I wonder if a clean gcc 4.6 is able to build binaries for
Mac OS X and if they're stable. Do you know anything about this subject?

Perhaps switching to gcc 4.6 will also get debugging symbols working, so
it sure is interesting to do some more research :)

Kind regards,

Erik
