I am trying to use the boost graph library in C++* I want to create a topological sort for my graph. However the output I want on my graph is the actual names of the vertex, not the number positions. For example on the following example I get the following output: A topological ordering: 45 40 41 34 35 33 43 30 31 36 32 26 27 25 23 24 1...
I'm writing a UDP server that currently receives data from UDP wraps it up in an object and places them into a concurrent queue. The concurrent queue is the implementation provided here: http://www.justsoftwaresolutions.co.uk/threading/implementing-a-thread-safe-queue-using-condition-variables.html A pool of worker threads pull data ou...
Hi, I have tried various approaches to fixing this issue with maps and casts, splitting the parse into different sub-pieces, using std::vector directly and trying _r1 etc. but I seem to have failed to grasp something fundamental about the use of attributes. I want to parse a line such as: DEFMACRO macroname param1 param2 param3 ... pa...
I work on a cross-platform (Windows, Linux, Solaris) project. I want to use Boost's shared_ptr in this project. How can I install it, and redistribute it with the project to the customers? I don't have root permissions on Linux/Solaris, so I probably have to add Boost' sources to my sources, and build it together. Also, our version of...
While doing the data/time parsing in c++ (converting a string in any format to a date), i found the following useful methods 1) strptime() - here the %d, %m etc can have either 1 or 2 characters. The function will take care of that. As a result of this it will enforce that we use a separator between two conversion specifiers. Ex: Its n...
Hello! I spend some time examining boost:: libraries architecture and was interested with the following fact: In some parts of the libraries a yyy_fwd.hpp idea is used pretty common (see boost/detail or boost/flyweight for examples). These files obviously contain only forward declarations of some template-based classes and as far as I...
I am currently involved in the development of a software using distributed computing to detect different events. The current approach is : a dozen of threads are running simultaneously on different (physical) computers. Each event is assigned a number ; and every thread broadcasts its detected events to the other and filters the releva...
Hi! I'm working on an application where I need to send a "filename", "filesize" and the filedata over the network. I created a server using boost which, for now, reads in the filesize and name. I'm wondering how I can fill a buffer with the file data (if necessary) and how to transfer it to the server. This is what I've got now: #i...
So, the code I started with and which works (with important caveats below) int reply_length = boost::asio::read(*m_socketptr, boost::asio::buffer((char*)reply, 6)); This works, I get the header which I then decode and follow up with another read which gets me my message and then I loop back to the top and read another header. This pe...
Hi, I'm trying to do some kind of Macro "Overloading", so that MACRO(something), gets expanded differently than MACRO(something, else). Using a snippet I got from here (I'm not sure if it's 100% portable) and some functions from the Boost PP Library, I was able to make it work :D //THESE TWO COUNT THE NUMBER OF ARGUMENTS #define VA_NA...
Hi All, I just downloaded the source code of facebook's scribe. I'm new to it and having read the readme.build file , I can say I could barely understand how to build it. Could anyone give me the step by step procedures? thanks... :) ...
I'm trying to view the boost documentation at their website: http://www.boost.org/doc/ But it says Forbidden. Any way I can download the documentation, or get past this error? ...
I implemented an iterator, which has Fibonacci numbers as output. In my main() I'd like to find a number which is dividable by 17 (it's 34). Why doesn't work my find_if statement. Thank you! #include <boost/operators.hpp> #include <algorithm> #include <tr1/functional> struct FibIter: boost::input_iterator_helper<FibIter,uns...
I am using UDP in particular boost::asio::ip::udp::socket sockets if that helps? What is the header file? What headers/classes do I need to handle network byte ordering with the UDP under boost? ...
boost signals allows temporarily blocking a connection via a connection member function. However, I have a single signal with many connections. The connections are stored and maintained by their respective listeners. Now the broadcaster decides that it wants to stop sending signals for a while. There does not seem to be a way to iterate ...
Does anybody have some example code showing the pipeline of serializing a std::string sending it through a boost::interprocess::message_queue and getting it back out again? ...
Hello everyone, I'm working with some code which writes to a wostream. I'd like take its output and write it to a gzip'ed file. This seemed like a good job for boost::iostreams. However, my attempts so far at this haven't been successful. (in all the below, assume using namespace boost::iostreams and that I have some function void my_...
i am using microsoft visual c++ 2010 can i use boost library or does it requires different compiler? ...
TLDR Linking my fresh boost build with Visual Studio (/Mtd) causes boost to throw a 'bad_alloc' exception before entering the main function. Details I built the boost library using the instructions from the Getting Started instructions. After setting up the prerequisites I used the following build command: bjam -j8 --build-dir="C:\De...
Is there any way to use the += operator with a vector without using boost or using a derivated class? Eg. somevector += 1, 2, 3, 4, 5, 6, 7; would actually be somevector.push_back(1); somevector.push_back(2); somevector.push_back(3); etc. ...
