Boost Graph Library: parallel edge removal problem
by Tiago de Paula Peixoto 25 Nov '04

25 Nov '04

Hello. I believe I found a bug in the remove_edge function, when the graph is directed and allows parallel edges. Sometimes an edge simply isn't removed. I think the problem is that remove_edge uses edge_range internally, but this function needs an ordered EdgeList (such as multisetS), and doesn't work properly when it's something like listS. The attached file shows the problem. It builds a simple graph with a loop, adds a parallel edge, and tries to remove it. The output of the program is: number of edges before removal: 5 number of edges after removal: 5 When EdgeList is changed from listS to multisetS, it works as it should: number of edges before removal: 5 number of edges after removal: 4 I'm using Boost 1.32.0, with GCC 3.4.3 on GNU/Linux. Thanks. -- Tiago de Paula Peixoto <tiago(a)forked.de>

address of member operator() function defined with member templates!
by Paul Elliott 25 Nov '04

25 Nov '04

This may be an general C++ question but: I want to take the address of a member function that happens to be an operator() operator, which is defined with member templates in apply.hpp: --------------quote---- namespace boost { template<class R> struct apply { typedef R result_type; template<class F> result_type operator()(F & f) const { return f(); } template<class F, class A1> result_type operator()(F & f, A1 & a1) const { return f(a1); } -------end quote. I want to take the address of operator() for <int,int> which is defined by the member template above. ----Quote--- // want to work with functions of the form int f(int); typedef int P(int); boost::function<int (P)> f = // boost::bind(boost::apply<int>(),_1,5); // above works but instead try below! boost::bind(&boost::apply<int>::operator()<int,int>,5); // above line produces error. ----end quote I get error message: exabind.cpp:23: error: no matching function for call to `bind(<unknown type>, boost::apply<int>, int)' How do I specify a pointer to the member operator() method defined with member template parameters <int,int> ? I must be doing something wrong. My brain hurts. -- Paul Elliott 1(512)837-1096 pelliott(a)io.com PMB 181, 11900 Metric Blvd Suite J http://www.io.com/~pelliott/pme/ Austin TX 78758-3117

Graphviz vs boost.Graph: which is recommended?
by Dan Dimerman 24 Nov '04

24 Nov '04

Hello, I am about to start a subproject that takes a graph, computes a layout and draws it on screen (Windows XP). I thought about using AT&T's well known graphviz library until I saw that on boost 1.32 there's a new algorithm: "boost::kamada_kawai_spring_layout". Although I am tempted to use boost's lib, tradition dictates that a longer/better tested and implemented library is the way to go. Do you happen to have any experience in this kind of problem (drawing graphs)? Any suggestions/ caveats ? Thanks... --- Outgoing mail is certified Virus Free.

compiling 1_32 in release mode brings the computer to its knees (Modified by Yarden Livnat)
by Mail Delivery Subsystem 24 Nov '04

24 Nov '04

Hi, I'm trying to compile 1_32 on OSX with the latest gcc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1666) however, while the debug version compile in just a few minutes, the 'release' start trashing on : libs/serialization/src/xml_grammar.cpp libs/serialization/src/xml_wgrammar.cpp in effect the compilation takes all the memory and then pages endlessly for hours, bringing the machine down to its knees. my compile command is: sudo bjam -sTOOLS=darwin "-sBUILD=release <threading>multi <define>BOOST_SIGNALS_NAMESPACE=Signals " install where the <define> is for Qt, Anybody has a clue why this is happaning and how to get the compilation to complete (other then copy the two .o from the debug tree into the release tree ? thanks Yarden

I have considered this and it still may be the answer or lead to an answer. Yes indeed they have separate heaps It may explain why the leak is steeper depending on what the function does. However I do remember had one experiment where i filled up a vector with a load of stuff and hey presto, no leak. if I have a function that allocates and deallocates memory on the heap and I use it as a thread using boost::thread, then when memory deallocations are performed by that thread is it the boost dll that is doing the deallocation or is it my exe? One would assume it was my exe since the deallocation code is in my exe. Surely there is no code in the threads dll to deallocate my memory. And I never ever get a crash, just a leak.

transform_iterator and lambda functors

24 Nov '04

Hello, I am trying to use transform_iterator with a lambda functor, but the compiler complains that the lambda functor does not contain a type called 'result_type', which the transform_iterator requires. I would have expected lambda functors to have this type. Any ideas on why it doesn't? Here is the code line causing the problem: return make_transform_iterator(attributes.begin(), bind(&pair<const AttributeType, string>::second, _1)); where attributes is of type map<AttributeType, string>. Here is the error message: /usr/local/include/boost-1_32/boost/iterator/transform_iterator.hpp:43: no type named `result_type' in `class boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::action<2, boost::lambda::function_action<2, boost::lambda::detail::unspecified> >, boost::tuples::tuple<std::string std::pair<const AttributeType, std::string>::*, const boost::lambda::lambda_functor<boost::lambda::placeholder<1> >, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type, boost::tuples::null_type> > >' Thanks, Rodrigo
