Hi Frank, Your patch resolves the error I posted before, but there are still other, similar errors while compiling other Boost.Python sources. I think this is the problem: shared_ptr.hpp: if(del_wrapper) del = del_wrapper->get_deleter<D>(); ^^^ ^^^ I think gcc 3.2 doesn't support this syntax. In the old days this was a common problem. The usual workaround is to use a type holder. See the patch below, which resolves all my compilation errors. Ralf P.S.: I bet there must be a central type holder in boost somewhere, but I couldn't find it.
