I am wrapping a C++-based data storage library for python using boost. The library is like this: class Container ... Piece* get(int index) ... ... class Piece ... Each Container (object) is composed of several Pieces. When Container.get is called it will return a pointer to Piece inside Container instead of a full copy. The pro...
I added following at line 42 of proto.h: typedef boost::make_unsigned<off_t>::type uoff_t; And now I get this verbose and confusing warning from gcc complaining about comparing an enum to the same enum type: In file included from proto.cpp:12: /usr/local/include/boost/type_traits/is_unsigned.hpp: In instantiation of 'boost::detail::i...
Firstly, I want to have a clearly overall look at MFC, Win32API . Is: Win32API: The first layer between hardware and software in prog [ except assembly ] MFC : A wrapper by Microsoft ? It helps us in design GUI and a lot of library for easier and faster programming. My problem is : I want an easy coding in GUI, no need to write every ...
I've only been working with Boost.Spirit (from Boost 1.44) for three days, trying to parse raw e-mail messages by way of the exact grammar in RFC2822. I thought I was starting to understand it and get somewhere, but then I ran into a problem: #include <iostream> #include <boost/spirit/include/qi.hpp> namespace qi = boost::spirit::qi; u...
I've seen two recent answers using _1 as a pure C++0x solution (no explicit mention of boost lambdas). Is there such an animal as std::_1 I would think that having native lambdas will make such a construct redundant. A Google code search for std::_1 brings two results from the same project so that's inconclusive. ...
Please could you explain why given the following boost::regex pattern: boost::regex re("/\\S+\\w"); /index.html is a match and /~index.html is not? RegexBuddy in Perl mode finds a match in both cases. Could you suggest a pattern that would work? Thanks!! P.S. The \\w at the end is needed in order to ignore the punctuation on the en...
For a little library project I'm using boost::tuple. Right now, I'm facing the problem of turning a "cons list" I operated on via metaprogramming back to a boost::tuple<...> type. The "dirty" solution would be to provide lots of partial specialications a la template<class T> struct id{typedef T type;}; template<class TL> struct type_li...
boost::mpl::integral_c is declared as: template <typename T, T N> struct integral_c; Is it possible to register this sort of template with Boost.Typeof: For any T? For some T's? ...
Hi, Suppose you have a certain template that takes a parameter class template <typename ConnectorClass> struct myClass { } I want to add a BOOST_ASSERT_MSG to validate that ConnectorClass implements a certain method of signature returnType MethodName(param1, param2) How should i write the assert condition in this case? EDIT: si...
Hello. I'm working with gnump and have a function that must return mpz_t. So I have to use raw pointers to return a value. I allocate space with new for pointer and send it as a parameter in my function. I think it is better to use smart pointers. But I didn't work with them before. I read the manual but still can't understand how to ...
In order to install Python XMP Toolkit, I need to install Exempi on my Mac, but doing this is becoming a real nightmare... After a lot of trouble, i finally made it with boost, and had the fantastic The Boost C++ Libraries were successfully built! The following directory should be added to compiler include paths: /usr/loc...
I am relatively new to using Boost MPI. I have got the libraries installed, the code compiles, but I am getting a very odd error - some integer data received by the slave nodes is not what was sent by the master. What is going on? I am using boost version 1.42.0, compiling the code using mpic++ (which wraps g++ on one cluster and icpc o...
I´m working with Spirit 2.4 and I'd want to parse a structure like this: Text{text_field}; The point is that in text_field is a escaped string with the symbols '{', '}' and '\'. I would like to create a parser for this using qi. I've been trying this: using boost::spirit::standard::char_; using boost::spirit::standard::string; usi...
I am looking for the best way to solve the following (c++) problem. I have a function given by some framework, which returns an object. Sometimes it takes just miliseconds, but on some occasions it takes minutes. So i want to stop the execution if it takes longer than let's say 2 seconds. I was thinking about doing it with boost threads...
I have the following in a for loop and the compiler says 'operator = is ambiguous'. Not sure how to solve this issue, can anyone help? rootelement = document->getDocumentElement(); boost::interprocess::unique_ptr<DOMNodeIterator, release_deleter> itera (document->createNodeIterator(rootelement, DOMNodeFilter::SHOW_ALL, NULL, true))...
Hi, I'm trying to understand how boost interprocess library works. I have an Equipment class which holds integer values in a vector container. In parent parent process; I constructed Equipment object in MySegmentObject segment, and in the constructor of this object I created the vector in MySegmentVector segment. Using child process;...
I was reading over Boost ConceptCheck today, and encountered this warning in the implementation page: This documentation is out-of-date; similar but newer implementation techniques are now used. This documentation also refers to components and protocols in the library's old interace such as BOOST_CLASS_REQUIRES and constraints() fun...
I wanted to be able to have something like Java's interface semantics with C++. At first, I had used boost::signal to callback explicitly registered member functions for a given event. This worked really well. But then I decided that some pools of function callbacks were related and it made sense to abstract them and register for al...
Hi all, I'm experimenting with Boost::asio, and I'm trying to make a client that reads and outputs to console packets sent from a server. The server uses a proprietary protolcol. It sends a timer update every second, responds to ping, and can reply with a list of files when the client asks for it. I have a decent grasp of asynchronous n...
