It did help. I have attached a patch that I think should do the job. I
have also attached error output from building the Boost source from the
anonymous CVS repository as of about an hour ago. The majority of the
errors come from the iostreams library. I cannot get it to build on Fedora
Core 3 using GCC 3.4.3 either, so I may be doing something wrong. The
errors from the two platforms are not exactly the same, and I cannot say for
sure at this time why I cannot get it to build.
The error that is disappointing to me is an internal compiler error when
trying to compile an optimized version of one of the Boost.Python .cpp files
(boost/libs/python/src/object/function.cpp to be specific). The only way I
can get it to compile is to change the speed optimization setting from -O3
to -O0. I have submitted a bug report to Apple. My hope with that is that
it's a bug in the GCC 4.0 pre-release snapshot used for OS X Tiger that will
be fixed in Mac OS X 10.4.1.
On the upside, I can compile the boost_wserialization library with GCC 4.0
on OS X Tiger. GCC 3.3 in OS X Panther used to get stuck indefinitely on
the file boost/libs/serialization/src/xml_grammar.cpp when building the
optimized version of boost_wserialization, but that doesn't happen with GCC 4.0.
