I have successfully built using gcc 4.9.0 and clang 3.4 on Mac OS X 9.4.
It successfully built using gcc 4.7.2 on Ubuntu 12.10, although with a couple of warnings: gcc.compile.c++ bin.v2/libs/python/build/gcc-4.7/release/link-static/threading-multi/object/enum.o libs/python/src/object/enum.cpp: In function ‘boost::python::api::object boost::python::objects::{anonymous}::new_enum_type(const char*, const char*)’: libs/python/src/object/enum.cpp:150:11: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] gcc.compile.c++ bin.v2/libs/python/build/gcc-4.7/release/link-static/threading-multi/object/class.o libs/python/src/object/class.cpp: In function ‘PyObject* boost::python::objects::static_data()’: libs/python/src/object/class.cpp:211:11: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/class.cpp: In function ‘boost::python::type_handle boost::python::objects::class_metatype()’: libs/python/src/object/class.cpp:319:11: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/class.cpp: In function ‘boost::python::type_handle boost::python::objects::class_type()’: libs/python/src/object/class.cpp:473:11: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] gcc.compile.c++ bin.v2/libs/python/build/gcc-4.7/release/link-static/threading-multi/object/function.o libs/python/src/object/function.cpp: In constructor ‘boost::python::objects::function::function(const boost::python::objects::py_function&, const boost::python::detail::keyword*, unsigned int)’: libs/python/src/object/function.cpp:108:9: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/function.cpp:110:9: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] gcc.compile.c++ bin.v2/libs/python/build/gcc-4.7/release/link-static/threading-multi/object/inheritance.o gcc.compile.c++ bin.v2/libs/python/build/gcc-4.7/release/link-static/threading-multi/object/life_support.o libs/python/src/object/life_support.cpp: In function ‘PyObject* boost::python::objects::make_nurse_and_patient(PyObject*, PyObject*)’: libs/python/src/object/life_support.cpp:94:9: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/life_support.cpp:96:9: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] - Alex
