[bgl]Shouldn't floyd_warshall_all_pairs_shortest use compare instead of min
by Peter Gerell 16 Feb '06

16 Feb '06

Hi, I am trying to calculate all pairs longest path withous any success using floyd-warshall in this way. floyd_warshall_all_pairs_shortest_paths(g, D, distance_compare(std::greater<int>()).distance_inf(std::numeric_limits<int>::min())); The problem seems to be the test within the three loops of floyd_warshall_dispatch. This function selects the minimum value using std::min instead of the maximal that would have been selected if the test had been implemented using compare. Is this a bug, or shouldn't it be possible to use the function like this? I have also found a problem in example/min_max_paths.cpp. The example tries to calculate the longest path in a graph with cycles of positive weight. Thanks, Peter

Member function as a thread function
by Steven Wooding 16 Feb '06

16 Feb '06

Hi, I've had a good search on the mailing list and while some posts have got close to my problem and given me a few glues, my code does't quite work the way I want it to. My goal is to have a (non-static) class member function run in a child thread + passing a parameter to it. The code I've got at the moment goes something like this: void MyClass::spawn_threads() { for ( int ii = 0; ii < num_threads; ++ii) { threadGroup.create_thread( boost::bind( ChildThreadFunc, _1, ii)); } } void MyClass::ChildThreadFunc( int &threadNumber) { // Does some work } I get the following error on the create_thread line: error: no matching function call to bind(<unknown type>, boost::arg<1>&, int&) cadiates are: .... boost:bind(F, A1, A2)[ with F= void (MyClass::*)(int&), A1=boost:arg<1>, A2=int] I'm confused by the <unknown type> business. How do I tell it the correct type? Maybe someone could point out where I've erred. Cheers, Steve.

[serialization] Really strange error that crashes the application
by Scott 16 Feb '06

16 Feb '06

I'm developing a client/server application using asio for communication and boost::serialization as the means to stream the objects between the two applications. This is on Windows XP with Microsoft Visual Studio 7.1. Everything works fine until this sequence of events happens: 1) The server shuts down gracefully and serializes some classes to a file. 2) The server restarts and reads in the file, loading the settings and replacing the default settings 3) The client makes a request for an object from the server 4) The server dies with the following error: --------------------------- Microsoft Visual C++ Debug Library --------------------------- Debug Error! Program: c:\Dev\NwEngineD.exe This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. (Press Retry to debug the application) --------------------------- Abort Retry Ignore --------------------------- Now, if I skip loading of the previously saved file, none of this ever happens. Everything works just fine. The following is the call stack when the error occurs: > msvcr71d.dll!_NMSG_WRITE(int rterrnum=10) Line 195 C msvcr71d.dll!abort() Line 44 + 0x7 C msvcr71d.dll!_assert(const char * expr=0x003696dc,

Now, as I've said, if I don't try to read in the saved file, none of this occurs. As a matter of fact, if I just run this simple code upon server startup, the whole error above occurs: typedef unsigned int Handle; void Manager::load(const std::string &filename) { std::ifstream inFile; inFile.open(filename.c_str(), std::ios::binary); boost::archive::text_iarchive archiveFile(inFile); Handle handle = 0; ManagerNode node; archiveFile >> handle; if (handle != Handle(-1)) { // comment out the line below and everything works fine // NOTE: the line below works fine (does not blow up) // it only causes serialization to fail later. // Also notice that I don't actually do anything with node, // it just goes out of scope at procedure end archiveFile >> node; } } My apologies for not being able to provide a complete working program that mimics the error. I developed a whole test program to replicate the error, and of course, it works just fine. It does almost everything the server program does, except it doesn't use asio. My hope is the code above, call stack and error message is enough to pinpoint where the problem may be. If it isn't, please give me a general idea of how to proceed. Thanks for any help, Scott

newbie question on preferred method to use shared_ptrs
by Perry Smith 16 Feb '06

16 Feb '06

Hi, I often have to "fight" with my C++ code and I must be missing a basic design characteristic of C++. Suppose there is a shared_ptr that has already been created. I now want to create an object with new and "give" it to shared_ptr to manage. I tend to do this: std::tr1::shared_ptr<int> dog; int fun(void) { int *temp = new int; dog = temp; // ... } This does not work. I've discovered two ways to achieve (I think) what I'm looking for: int fun(void) { std::tr1::shared_ptr<int> temp(new int); dog = temp; // ... } or ... int fun(void) { foo *temp = new int; dog.reset(temp); // ... } The first has the extra overhead of creating a second shared_ptr. The second worries me... It just seems like "reset" is not what I would call the method to do what I want to do (but maybe it is). Anyone care to help me out here? Thanks, Perry

Boost bind library question
by Meryl Silverburgh 15 Feb '06

15 Feb '06

How can I use boost:bind library to bind to constructor of a class. Right now, I have code like this: class build { public: Rect* operator()(string& str) { return new Rect(str); } }; void TestBlockData::buildRectList( vector<string>& inputs, RectList& bdl) { transform(inputs.begin(), inputs.end(), bdl.begin(), build()); } I wonder if I can get rid of the whole "build class" by using boost::bind library. Thank you.

using filtering_istream for decompression
by Ed Sykes 15 Feb '06

15 Feb '06

Hi, I'm trying to use a filtering istream with a gzip decompressor attached. I've got it all working but the one part that I am having trouble with is figuring out the most effective way of consuming the decompressed data. I'd like to be able to get hold of all the decompressed data in one go, rather than reading out a word at a time using the >> operator. It seems to me that the most logical way of doing it, given what I have read about the way streams work, would be to use rdbuf() to get the streambuffer and then send that to a stringstream. However when I try this the filtering_istream throws an exception of type boost::iostreams::gzip_error. I do know however that the data integrity is fine since I am able to use >> to push data into a std::string. Instinctively I realise that the filtering_istream doesn't have an internal buffer as such and using the >> operator pulls data from the source, through the decompressor and into the type on the right hand side. This leaves me confused as to what the best way of getting the data out is if I can't use the filtering_istream as a typical stream inheriting from basic_istream. I think that perhaps I'm misunderstanding a fundamental principle of how to use the filtering_istream and I'm hoping that someone on the list can point me in the right direction of how I should achieve a read of all the decompressed data. So does anyone have any idea how I should proceed? I've included the code I have thus far below.

Serialization Build Issues
by Arpan Sen 15 Feb '06

15 Feb '06

Hello everyone, I am attempting to build a single threaded static debug library of the boost serialization project, using the vc_7-1-stlport toolset. The only consideration being that the iostream library should be the native one. This has turned out to be quite a pain owing to the following reasons: 1. I could not figure out any know cmdline options to get this done. So, I hacked the stl_user_config.h and added the _STLP_NO_OWN_IOSTREAMS macro after which I start getting the compiler error "../include/iostream.h" --> No such file or directory. I was thinking that this is an issue with paths, but i do have an iostream.h inside Vc7/include. 2. The cmdline that I was using had the <threading>single option but that somehow did not work. I had to hack jam scripts to get things working but not sure if that was the only available option or am i missing something. I am using bjam 3.1.0. Any help appreciated. -- Regards, Arpan

"The message suggests that the serialization libraries are not linked in.This would likely be an issue with link command line." The command i used to compile the demo is g++ demo.cpp -L/home/newton6/rwm33/usr/lib -lboost_serialization-gcc-mt-d -o demo I tried other variations of: g++ demo.cpp -L/home/newton6/rwm33/usr/lib -lboost_serialization-gcc-mt -o demo g++ demo.cpp -L/home/newton6/rwm33/usr/lib -lboost_serialization-gcc -o demo Should i be linking with something else? Thanks, Ryan McKeown Drexel University Physics Dept.

Dunno about G++. We're forced to use xlC at work. All I can say is some of the libraries work, some of them don't. At least with our version.
