[python] missing image in docs.
by John Maddock 02 May '05

02 May '05

The python tutorial references the image libs/python/doc/tutorial/doc/images/jam.png which is not in cvs, any chance of a fix? Thanks, John.

[property_map] Broken style sheet in property_map docs.
by John Maddock 02 May '05

02 May '05

The property_map docs reference the style sheet libs/property_map/doc/default.css, which does not actually exist in cvs, should this use the boost.css, or is there a missing library specific style sheet waiting for checkin? Thanks, John.

BGL documentation bugs
by Felipe Magno de Almeida 02 May '05

in the file: http://www.boost.org/libs/graph/doc/quick_tour.html there's an extra comma at the end of the declaration: Edge edge_array[] = { Edge(A,B), Edge(A,D), Edge(C,A), Edge(D,C), Edge(C,E), Edge(B,D), Edge(D,E), }; And a little after appears this line: Graph g(edge_array, edge_array + sizeof(edge_array) / sizeof(E), num_vertices); but I think the correct should be: Graph g(edge_array, edge_array + sizeof(edge_array) / sizeof(Edge), num_vertices); Since the first gives a segmentation faul and I think doesnt make too much sense to use sizeof(E)... -- Felipe Magno de Almeida UIN: 2113442 email: felipe.almeida at ic unicamp br, felipe.m.almeida at gmail com, felipe at synergy com I am a C, modern C++, MFC, ODBC, Windows Services, MAPI developer from synergy, and Computer Science student from State University of Campinas(UNICAMP).

Re: [Boost-users] Boost Graph Library and Boehm Garbage Collector

(the "new" which is causing the leak(or one of your leaks?) in your code is at line 278 of graph/detail/adjacency_list.hpp in version 1.32) -- Stefan Strasser

BGL::johnson_all_pairs_shortest_path question
by Andreas Fabri 02 May '05

02 May '05

Hello, What is the non-named parameter version of this algorithm. In the online manual it says Weight (and this is probably a typo, as there is a template parameter WeightMap). Also what are the arguments id1 and zero good for? andreas

These changes: http://build.redshift-software.com:9990/RSI-SoL-Full/builds/86 Are causing the processing of the jam logs to fail, and hence the inability to post test results: http://build.redshift-software.com:9990/RSI-SoL-Full/builds/86/boost.proces… Any ideas?

[graph] graph concepts in edmunds-karp algorithm are incomplete
by Peter Billen 02 May '05

02 May '05

Hello all, I believe the required graph concepts of the Edmunds-Karp algorithm are not complete. The online documentation says the given graph has to be a VertexListGraph. I believe it also has to be a IncidenceGraph, since the algorithm uses breadth-first search, which calls the out-edges of each node successively. Since the algorithm (and all flow algorithms) work on the edges of the graph, edges are needed somewhere, so VertexListGraph cannot be enough in my opinion. Is this correct? Thanks, -- Peter

tribool namespace problem with vc-7_1

Hello, is the following code correct? #include <boost/logic/tribool.hpp> using namespace boost; using namespace boost::logic; int main() { tribool tb; tribool &rtb = tb; rtb = indeterminate; } My Visual C++ Compiler 7.1 says "INTERNAL COMPILER ERROR". If i comment out "using namespace boost;" everything works fine... -- Sebastian Pfützner s.pfuetzner(a)onlinehome.de ICQ-ID: 39965036
