Ok, here's simpler code that demonstrates the same problem: #include <boost/function.hpp> #include <iostream.h> void FooBar(boost::function0<void> callback) { callback(); } void CallbackImpl() { cout << "Called back ok\n"; } int main(int argc, char* argv[]) { FooBar(CallbackImpl); return 0; } I'm stuck with Builder because we already have a major system built with it (don't look at me, it was coded by Mechanical and Automation Engeneers, I was hired later to deal with it, so you can guess the size of my problem). I plan on porting it to Visual Studio, but finding the time and resources to do that is probably years away. And I probably won't be here by then. OvermindDL1 escreveu:

I've just recently learned about boost::function when reading Effective C++, and I was thrilled about it.
This is the simple code I'm trying to implement:
typedef boost::function1<void, boost::shared_ptr<VarSpeedObject> > ObjectDoneCallback; void SomeFunction(ObjectDoneCallback callback, ...) { // Some code callback(...); }
When trying to compile it under C++ Builder 2006 (I have no other choice but to use this in the current project), I get the following error:
[C++ Error] function_template.hpp(904): E2131 Objects of type 'detail::function::basic_vtable1<void,shared_ptr<VarSpeedObject> >' cannot be initialized with { }
On this line in function_template.hpp: static vtable_type stored_vtable = { { &manager_type::manage }, &invoker_type::invoke };
Can I circumvent this somehow to make it compile under my environment?
Two things.
First, it is best to give is a complete, but simplified example that demonstrates the problem.
Second, the Borland builder has lots of issue, and that is putting it mildly. Why are you stuck with it? _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users ------------------------------------------------------------------------
