I am using this command to build boost 1_46_1. * ./bjam architecture=combined address-model=32_64 * and got following errors for almost every file: *./boost/python/detail/make_tuple.hpp:25: error: no matching function for call to \'91incref(<type error>)\'92\./boost/python/detail/make_tuple.hpp:25: error: \'91class boost::python::tuple\'92 has no member named \'91ptr\'92\ ./boost/python/detail/make_tuple.hpp:25: error: there are no arguments to \'91PyTuple_SET_ITEM\'92 that depend on a template parameter, so a declaration of \'91PyTuple_SET_ITEM\'92 must be available\* and "g++" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -dynamic -no-cpp-precomp -gdwarf-2 -Wno-long-double -fPIC -arch i386 -arch ppc -arch x86_64 -DBOOST_ALL_NO_LIB=1 -DBOOST_PYTHON_SOURCE -DNDEBUG -I"." -I"/System/Library/Frameworks/Python.framework/Versions/2.6/include/python2.6" -c -o "bin.v2/libs/python/build/darwin-4.0.1/release/address-model-32_64/architecture-combined/threading-multi/object/stl_iterator.o" "libs/python/src/object/stl_iterator.cpp"\ \ *...failed darwin.compile.c++ bin.v2/libs/python/build/darwin-4.0.1/release/address-model-32_64/architecture-combined/threading-multi/object/stl_iterator.o...\* please help me out if I am doing anything wrong or there is any other way of doing this. kind regards;
