when trying to compile the following code (cut from the boost.function test suite): #include <boost/bind.hpp> #include <boost/function.hpp> #include <iostream> #include <string> #include <functional> struct X { X(int v) : value(v) {} int twice() const { return 2*value; } int plus(int v) { return value + v; } int value; }; int main() { using namespace boost; boost::function<int, X*> f1(&X::twice); X one(1); cout << "f1(one) = " << f1(&one) << endl; return 0; } _____________________________________________ i get the following errors: /usr/local/include/boost/function/function_template.hpp: In function `static int boost::detail::function::function_obj_invoker1<int (X::*) () const,int,X *>::invoke(boost::detail::function::any_pointer, X *)': /usr/local/include/boost/function/function_template.hpp:689: instantiated from `boost::function1<int,X *,boost::empty_function_policy,boost::empty_function_mixin,allocator<b oost::function_base> >::assign_to<int (X::*)() const>(int (X::* &)() const, boost::detail::function::function_obj_tag)' /usr/local/include/boost/function/function_template.hpp:618: instantiated from `boost::function1<int,X *,boost::empty_function_policy,boost::empty_function_mixin,allocator<b oost::function_base> >::assign_to<int (X::*)() const>(int (X::* &)() const)' /usr/local/include/boost/function/function_template.hpp:463: instantiated from `boost::function1<int,X *,boost::empty_function_policy,boost::empty_function_mixin,allocator<b oost::function_base> >::function1<int (X::*)() const>(int (X::* &)() const)' /usr/local/include/boost/function.hpp:459: instantiated from `boost::function<int,X *,boost::detail::function::unusable,boost::detail::function::unusable, boost::detail::function::unusable,boost::detail::function::unusable,bo ost::detail::function::unusable,boost::detail::function::unusable,boos t::detail::function::unusable,boost::detail::function::unusable,boost: :detail::function::unusable>::function<int (X::*)() const>(int (X::* &)() const)' hello.C:21: instantiated from here /usr/local/include/boost/function/function_template.hpp:272: pointer to member function called, but not in class scope /usr/local/include/boost/function/function_template.hpp:272: warning: control reaches end of non-void function `boost::detail::function::function_obj_invoker1<int (X::*)() const,int,X *>::invoke(boost::detail::function::any_pointer, X *)' /usr/local/include/g++-3/stl_alloc.h: At top level: /usr/local/include/g++-3/stl_alloc.h: In instantiation of `allocator<int (X::*)() const>': /usr/local/include/boost/function/function_base.hpp:131: instantiated from `boost::detail::function::functor_manager<int (X::*) () const,allocator<boost::function_base> >' /usr/local/include/boost/function/function_template.hpp:691: instantiated from `boost::function1<int,X *,boost::empty_function_policy,boost::empty_function_mixin,allocator<b oost::function_base> >::assign_to<int (X::*)() const>(int (X::* &)() const, boost::detail::function::function_obj_tag)' /usr/local/include/boost/function/function_template.hpp:618: instantiated from `boost::function1<int,X *,boost::empty_function_policy,boost::empty_function_mixin,allocator<b oost::function_base> >::assign_to<int (X::*)() const>(int (X::* &)() const)' /usr/local/include/boost/function/function_template.hpp:463: instantiated from `boost::function1<int,X *,boost::empty_function_policy,boost::empty_function_mixin,allocator<b oost::function_base> >::function1<int (X::*)() const>(int (X::* &)() const)' /usr/local/include/boost/function.hpp:459: instantiated from `boost::function<int,X *,boost::detail::function::unusable,boost::detail::function::unusable, boost::detail::function::unusable,boost::detail::function::unusable,bo ost::detail::function::unusable,boost::detail::function::unusable,boos t::detail::function::unusable,boost::detail::function::unusable,boost: :detail::function::unusable>::function<int (X::*)() const>(int (X::* &)() const)' hello.C:21: instantiated from here /usr/local/include/g++-3/stl_alloc.h:750: `allocator<int (X::*)() const>::address(int (X::* &)() const) const' has already been declared in `allocator<int (X::*)() const>' make: *** [hello.o] Error 1 ___________________________________ this code should compile (its just copied from the test code) and my compiler setup should work according to the boost compiler status page. Any ideas what i'm doing wrong? -Darin Buck
