Boost libraries and no exceptions
by David Ward 08 Feb '05

08 Feb '05

Boosters: In our embedded environment, we compile everything with -fno-exceptions. I'm getting errors in the new program_options library because it has naked throw calls in it. I did see a definition of boost::throw_exception and changed the naked throw calls to use that. That seems to work. However, naked throw calls are littered throughout many of the libraries. Is there some generic way to get these libraries to compile with -fno-exceptions or do I have to go through and change all … [View More]

Bind question
by Surya Kiran Gullapalli 07 Feb '05

Hi all, This is a follow up to my previous message on boost::bind question. Please go thru the attached program. I've 2 structures X an Y, and i'm calling stable_sort on vectors of both the objects. But in one stable sort, i'm using the member variable directly, and in the other i'm using a member function to access that. When i use boost::bind with member variable directly, it has no problem (structure Y), But if i use member function to access the member variable, which is private, i'm … [View More]

Hi all, I'm having this particular class class File { public: int get_size(); std::string get_name(); private: int size, std::string name; } ; and a vector of objects of this class. vector <File> files ; and if want to sort the elements of the container i use stable_sort (files.begin(), files.end()) // Invokes operator < if its defined. otherwise shows up an error. there's another form of stable_sort, in which we can call a sorting function of our own. … [View More]

[signals] Painfully simple signals question

Shame be where it belongs, after rading documentation, implementation, examples and test code, I am unable to write what should be simple signals code: --------------------------------------------- *.h typedef boost::function<void (void)> Callback; struct Signal { static void Connect(Callback f); }; ------------------------------------------------ *.cpp boost::signal<void (void)> mySignal; void Signal::Connect(Callback f) { // iterate over signal slots, if slot equals … [View More]

Signals and fuction documentation really old?
by Tony Juricic 07 Feb '05

07 Feb '05

..or am I having a day of profound stupidity. documentation: Boost.Function 3.5 Comparing Boost.Function objects me: okay, boost function object wrapper objects are comparable. documentation: Chapter 5 FAQ 5.1 Comparison between boost::function objects cannot be implemented well, and therefore will not be implemented. me:okay so it is not implemented documentation: 5.1 This essentially negates the usefulness of operator==in the context in which it is most desired:multitarget callbacks. … [View More]

deepcpy_ptr
by gast128 06 Feb '05

Dear all, I couldn't find functionality a la deep copy pointer in boost. Isn't this an idea to extend the smart_ptr library with it? Basically it has the same functionality as if the object was hold by value, but sometimes you want to dismiss the header file and only have a fwd decl: #include "bla.hpp" struct Foo { Bla m_Bla; }; deep copy: class Bla; //fwd decl. is sufficient { deepcpy_ptr<Bla> m_ptr; }; Or do I overlook something? Wkr, me
