Hi folks,

the build of serialization in boost 1.44 fails when compiling for PPC Mac.

On a native Power PC with gcc 4.0.1 the build fails:

On an Intel Mac, with OSX 10.5 and gcc 4.2.1 the build fails when architecture=combined is added to the bjam command:

When using bjam without architecture=combined on an Intel Mac, the build succeeds.

That makes boost.serialization unusable on PCC, because it can neither be build native, nor for a universal binary.

I wonder how this could slip through the rigid testing procedures of boost...

OK - I can fix this, I'll upload the change to the trunk The fix consists of eliminating the line 75 in ./boost/archive/basic_binary_iarchive.hpp BOOST_STATIC_ASSERT(sizeof(tracking_type) == sizeof(bool)); For now you could just edit your own copy. Note that this configuration is not explicitly tested by boost. maybe you want to become a boost tester for it. This would guarentee that in the future your configuration would be "pre-tested" for you. Robert Ramey
