Hello Everyone, I am trying to compile boost 1.36.0 with gcc 4.1.2 on Fedora 7 and while compiling extension.cpp in boost.python, it triggers an internal compiler error --------- gcc.compile.c++ bin/gcc-4.1.2/debug/extending.o ../../../../boost/type_traits/detail/cv_traits_impl.hpp: In instantiation of ‘const bool boost::detail::cv_traits_imp<<unnamed>::hello*>::is_const’: ../../../../boost/type_traits/is_const.hpp:53: instantiated from ‘boost::is_const<<unnamed>::hello>’ ../../../../boost/python/detail/cv_category.hpp:31: instantiated from ‘boost::python::detail::cv_category<<unnamed>::hello>’ ../../../../boost/python/detail/unwind_type.hpp:58: instantiated from ‘typename Generator::result_type boost::python::detail::unwind_ptr_type(U*, Generator*) [with Generator = boost::python::converter::detail::unwind_type_id_helper, U = <unnamed>::hello]’ ../../../../boost/python/detail/unwind_type.hpp:127: instantiated from ‘static typename Generator::result_type boost::python::detail::unwind_helper2<2>::execute(U& (*)(), Generator*) [with Generator = boost::python::converter::detail::unwind_type_id_helper, U = <unnamed>::hello]’ ../../../../boost/python/detail/unwind_type.hpp:165: instantiated from ‘typename Generator::result_type boost::python::detail::unwind_type(boost::type<U>*, Generator*) [with Generator = boost::python::converter::detail::unwind_type_id_helper, U = <unnamed>::hello&]’ ../../../../boost/python/converter/pytype_function.hpp:45: instantiated from ‘boost::python::type_info boost::python::converter::detail::unwind_type_id_(boost::type<T>*, mpl_::false_*) [with T = <unnamed>::hello&]’ ../../../../boost/python/converter/pytype_function.hpp:68: instantiated from ‘static const PyTypeObject* boost::python::converter::expected_pytype_for_arg<T>::get_pytype() [with T = <unnamed>::hello&]’ ../../../../boost/python/detail/signature.hpp:98: instantiated from ‘static const boost::python::detail::signature_element* boost::python::detail::signature_arity<1u>::impl<Sig>::elements() [with Sig = boost::mpl::vector2<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, <unnamed>::hello&>]’ ../../../../boost/python/detail/caller.hpp:232: instantiated from ‘static boost::python::detail::py_func_sig_info boost::python::detail::caller_arity<1u>::impl<F, Policies, Sig>::signature() [with F = std::string (<unnamed>::hello::*)()const, Policies = boost::python::default_call_policies, Sig = boost::mpl::vector2<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, <unnamed>::hello&>]’ ../../../../boost/python/object/py_function.hpp:48: instantiated from ‘boost::python::detail::py_func_sig_info boost::python::objects::caller_py_function_impl<Caller>::signature() const [with Caller = boost::python::detail::caller<std::string (<unnamed>::hello::*)()const, boost::python::default_call_policies, boost::mpl::vector2<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, <unnamed>::hello&> >]’ extending.cpp:40: instantiated from here ../../../../boost/type_traits/detail/cv_traits_impl.hpp:37: internal compiler error: in make_rtl_for_nonlocal_decl, at cp/decl.c:5069 ------------- Is anyone else seeing this? Also has anyone had any luck compiling boost with the intel compiler suite (version 10.1) on linux? Thanks, Sameer
