Has anyone managed to use boost::function<> with Sun WorkShop 6 update 2? For me, it causes the compiler to core dump.

I don't believe anyone has gotten this to work, unfortunately. I have access to this compiler now, so I might be able to port boost::function to it.

Glad you're on it Doug - it's a very useful class on its own and essential for boost::threads. If any one's interested, I've whipped up a rough version of boost::function (which only handles functors). It's enough to get boost::threads working. Simon class function_holder_base // detail { public: virtual ~function_holder_base() {} virtual void operator()() = 0; virtual function_holder_base* copy() const = 0; }; #endif // !defined(WU_FUNCTION_HOLDER_BASE_H_) template<typename F> class function_holder : public function_holder_base // detail { public: function_holder(const F& f) : m_f(f) {} ~function_holder() {} void operator()() { m_f(); } function_holder_base* copy() const { return new function_holder(*this); } private: F m_f; }; class function { public: template<typename F> function(const F& fb) : m_fb(new function_holder<F>(fb)) {} function(const function& r) : m_fb( (r.m_fb)->copy() ) {} function() : m_fb(0) {} function& operator=(const function& r) { std::auto_ptr fb( (r.m_fb)-

copy() ); if(fb.get()) { delete m_fb; m_fb = fb.release(); } return *this; } ~function() { delete m_fb; } void operator()() { m_fb->operator()(); } operator bool() const { return m_fb != 0; } void clear() { delete m_fb; m_fb = 0; }

private: function_holder_base* m_fb; };
