Why did you make this link?

That might be the cause of your problems. From other sources I consulted it
seems that "ld" is not smart enough to handle C++ linking.
The prefered method is to use "c++" to do the linking.

That actually makes some sense given what I've seen in other places. Using
"c++" instead of "ld" will make sure the extra C++ init/link information is

After looking at your changes and other build sources for Darwin I decided
it was not worth it to try and change the gcc-toolset.jam to accomodate
Darwin. It's just too different, and would just complicate it, not that it's
simple now ;-\
Instead I created a new toolset, "drawin-tools.jam" to accomodate
MacOSX/Darwin better. The lates Boost CVS state has the toolset, and some
minor changes to "allyourbase.jam". You can get the two files at
This is a first pass, and you'll have to tell me if it works.
I did not add the "-framework Python" as this is something that should go on
Python specific code only. So for that I added a free feature one can use to
add frameworks to the link. For now though go ahead an add it directly, and
any other changes too, until we get it working.
One warning... I'm using a single "c++" invocation for linking and that may
not work. If this is the problem you run into I have a two step method of
doing the linking which might also work.
Your welcome :-)
