[test] spurious clang complier warnings
by Ian Emmons 10 Mar '13

10 Mar '13

When I compile my test code with clang on Macintosh (now Apple's default compiler), I get the two compiler warnings listed below. Could these be suppressed, please? I know this is a low priority item, but I expect it's pretty easy to fix. -Ian Emmons ============================== In file included from MyTest.cpp:6: In file included from ./MyTest.h:7: In file included from /Users/iemmons/dev/boost_1_53_0/boost/test/unit_test.hpp:19: In file included from /Users/iemmons/dev/boost_1_53_0/… [View More]

boost::interprocess::unique_ptr vs Boost.SmartPtr
by Adam Romanek 09 Mar '13

09 Mar '13

Hi! If I'm correct then the first "serious" implementation of unique_ptr for C++03 was written by Howard Hinnant, which was later adopted to Boost.Interprocess library. Unfortunately, I suppose not many people are aware of the fact that unique_ptr for C++03 is available in Boost. Even worse, I know people who are aware of it but who are afraid of using it just because it is provided by Boost.Interprocess, not by Boost.SmartPtr. Therefore, here's my proposal: - boost::interprocess::… [View More]

Context support for power architecture and mach-o ABI
by John Gleeson 09 Mar '13

09 Mar '13

I am interested in developing *ppc*_macho_gas.S implementations for the Boost.Context library. Has anyone already done some work on this combination? Any suggestions are welcome. I have prior experience in assembly programming and some understanding of processor scheduling concepts, but I have not done any work in these areas for a long time. I expect my re-learning curve to be steep. Thanks, John

[Serialization] Link issue on Mac OSX 10.8 (Mountain lion)
by Sean Farrow 08 Mar '13

08 Mar '13

Hi, I'm currently working with a client and we are facing an issue where by we can successfully build the boost libraries using the version of gcc that comes with xcode 4.6. However when we try to compile a project including serialization, the library and hence symbols cannot be found. We are using the latest mac os (mountain lion) and xcode 4.6. The strange thing is that this all worked under SnowLepard. If anyone can help this would be much appreciated. Moving to clang is not an option due … [View More]to other dependencies.

It looks like this library is some kind of abstraction around OpenCL.

[graph]Direct Edge Access
by Takatoshi Kondo 08 Mar '13

08 Mar '13

Hello, I'm using Boost.Graph version 1.53.0. I'm trying to write some graph algorithms and I want to minimize the requirements of the input graph. I have a question about Boost.Graph concepts. I wrote a very simple code as follows: typedef boost::adjacency_list< boost::vecS, boost::vecS, boost::bidirectionalS> G; int main() { G g; boost::add_edge(0, 1, g); auto res = boost::edge(0, 1, g); // Why can I call it? std::cout << std::boolalpha << res.… [View More]second << std::endl; boost::graph_traits<G>::edge_descriptor e = res.first; std::cout << boost::source(e, g) << "," << boost::target(e, g) << std::endl; } It works, but I don't understand why I can call boost::edge(). According to the following document, AdjacencyMatrix concept provides Direct Edge Access functionality, so I can call edge(u,v,g) : http://www.boost.org/doc/libs/1_53_0/libs/graph/doc/AdjacencyMatrix.html The class template adjacency_list is a model of VertexAndEdgeListGraph, MutablePropertyGraph, CopyConstructible, Assignable, and Serializable. http://www.boost.org/doc/libs/1_53_0/libs/graph/doc/adjacency_list.html So, adjacency_list is not satisfied AdjacencyMatrix concept. I checked which function template is called, then I found the following function is called: boost/graph/detail/adjacency_list.hpp:1582 template <class Config, class Base> inline std::pair<typename Config::edge_descriptor, bool> edge(typename Config::vertex_descriptor u, typename Config::vertex_descriptor v, const adj_list_helper<Config, Base>& g_) { typedef typename Config::graph_type Graph; typedef typename Config::StoredEdge StoredEdge; const Graph& cg = static_cast<const Graph&>(g_); typedef typename Config::out_edge_iterator out_edge_iterator; const typename Config::OutEdgeList& el = cg.out_edge_list(u); typename Config::OutEdgeList::const_iterator it = graph_detail:: find(el, StoredEdge(v)); return std::make_pair( typename Config::edge_descriptor (u, v, (it == el.end() ? 0 : &(*it).get_property())), (it != el.end())); } Also, I found the following document: http://www.boost.org/doc/libs/1_53_0/libs/graph/doc/using_adjacency_list.ht… This document describes that: edge() The time complexity for this operation is O(E/V) when the OutEdgeList type is a Sequence and it is O(log(E/V)) when the OutEdgeList type is an AssociativeContainer. It seems that edge() is a part of the public interface of adjacency_list. But I think that it is not a part of any graph concepts. If I want to write an algorithm that depends on several graph concepts, not actual classes such as adjancency_list, I can use edge(u,v,g) only if the input graph class satisfies AdjacencyMatrix concept. Am I understanding correctly? Thanks, Taka [View Less]

Re: [boost] [locale] Memory leaks?

You had mistaken "reachable" code with memory leaks... Especially if some std::locale::global remains etc. It is not a bug nor even a problem.

[Graph][Parallel][PBGL] Bug deleting self loop edges
by bminano 07 Mar '13

07 Mar '13

Hello, I think I found a bug in the graph parallel library. I have a bidirectional adjacency list which has some self loop edges. When I try to delete them with remove_edge_if (or remove_out_edge_if or remove_in_edge_if) the edges are deleted, but it seems that some reference gets broken in the graph. If I iterate over the in_edges a reference to a self loop is found. But it does not happen if I iterate over the out_edges. If the graph is written in a graphviz file the self loop edges … [View More]
