[BGL] problem with adjacency_list and bidirectional_tag
by Tiago de Paula Peixoto 02 Jun '06

02 Jun '06

Hi. I've noted an apparent discrepancy between the documentation of the adjacency_list class and the actual behavior: It's stated in the documentation that graph_traits<adjacency_list>::directed_category should be a typedef to "directed_tag" or "undirected_tag", depending on whether the graph is directed or not. Those are also the only possible types defined by the Graph concept. But when bidirectionalS is used as the Directed template parameter for adjacency_list, the type of the directed_category is set to "bidirectional_tag". Shouldn't this simply be set to "directed_tag", and the bidirectional information be confined to graph_traits<adjacency_list>::transversal_category? At least that's what the documentation says... I didn't provide a test program, since this can easily be checked in the source code. I'm using boost 1.33.1 and GCC 4.1.0. Thanks. -- Tiago de Paula Peixoto <tiago(a)forked.de>

When Boost::signals will be thread-safe?
by Tanguy Krotoff 02 Jun '06

02 Jun '06

Hi Boost::signals are not thread-safe http://boost.org/doc/html/signals/s04.html#id2738867 "Boost.Signals will support thread safety in the future." I would like to know when this feature will be implemented, if somebody is working on it. I like very much the fact that Qt slot/signals are thread safe, it helps really a *lot* : "the slot is invoked when control returns to the event loop of the thread to which the object belongs. The slot is executed in the thread where the receiver object lives." http://doc.trolltech.com/4.1/threads.html Do you plan also to make Boost::signals executed in the thread where the receive object lives? Thanks in advance for your answers Regards, -- Tanguy Krotoff <tanguy.krotoff(a)wengo.fr> http://openwengo.org

Poll: Do you use Spirit 1.6?
by Nicola Musatti 02 Jun '06

02 Jun '06

Hallo, This is a poll I started on the Spirit General mailing list which I'm reposting here as suggested by Joel de Guzman. I apologize to those who already read this message there. I'd be interested to know how many of you are currently using Spirit 1.6.x and with which compilers, to gauge the effort that might be required to take on maintenance of the 1.6 branch. Currently I'm using Spirit 1.6 with Borland's BCB6 and BCB2006, in conjunction with Boost.Serialization. Thank you, Nicola Musatti

Re: [Boost-users] [Test] Is It Possible to Put Test Cases in DLL?
by Wu Yinghui, Freddie 02 Jun '06

02 Jun '06

Hi Edwin, Thanks for your pointer. But how this small test framework is supposed to work out? The fact is that I've been using Boost.Test mostly with its auto test case capability (I don't want to have to write code to register my test cases one by one in general, unless that's the last resort). Therefore, I'm not very familiar with how such mechanism can work out by writing some test framework of my own... Would you mind to shed some more light on this?

boost::numeric::ublas matrix iterators
by Ed Johnson 01 Jun '06

01 Jun '06

Hi, I read through the Ublas documentation but did not see any examples with the iterator1 and iterator2 being used with a matrix. I am having trouble working with them. Does anyone know how to recreate this example using the iterators? http://www.boost.org/libs/numeric/ublas/doc/matrix.htm int main () { using namespace boost::numeric::ublas; matrix<double> m (3, 3); for (unsigned i = 0; i < m.size1 (); ++ i) for (unsigned j = 0; j < m.size2 (); ++ j) m (i, j) = 3 * i + j; std::cout << m << std::endl; } Many thanks, Ed Johnson

Using Boost.Build to link to boost libs
by Pierre THIERRY 01 Jun '06

01 Jun '06

Hi, I've read a great part of Boost.Build's documenation and taken a look i all the rest of it, but I don't quite understand of to use it to build to boost libs and arbitrary libs in general. If I have main.cpp that should be compiled to main, and uses boost::program_options, what should the Jamfile be? If it was any other lib, like POSIX threads or libbzip2, what would it be? That may sound quite simple, but I'm not sure it's clearly in the doc. :-/ Desperately, Nowhere man -- nowhere.man(a)levallois.eu.org OpenPGP 0xD9D50D8A

Pb compiling serialization on linux
by Thomas DAVID 01 Jun '06

01 Jun '06

Hi all, i've posted some time ago about a problem about how to serialize valarray with boost. The answer was to use the CVS version. But I have errors when i try to compile it. I downloaded the .rpm version of bjam, and installed it with alien and dpkg (i use Ubuntu). I used this command to launch the compilation : bjam --with-serialization I'm using : g++ (GCC) 3.4.6 (Ubuntu 3.4.6-1ubuntu2) and GNU ld version 2.16.91 2006011 I have many erros like this : `.L454' referenced in section `.rodata' of bin/boost/libs/serialization/build/libboost_serialization.so/gcc/debug/shared-linkable-true/array_binary_oarchive.o: defined in discarded section `.gnu.linkonce.t._ZNK5boost7archive17archive_exception4whatEv' of bin/boost/libs/serialization/build/libboost_serialization.so/gcc/debug/shared-linkable-true/array_binary_oarchive.o and collect2: ld a retourné 1 code d'état d'exécution (ld returned code 1) and at the end : ln -fs "libboost_serialization-gcc-mt-1_35.so.1.35.0" "bin/boost/libs/serialization/build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi/libboost_serialization-gcc-mt-1_35.so" ...failed gcc-Link-action bin/boost/libs/serialization/build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi/libboost_serialization-gcc-mt-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/debug/shared-linkable-true>libboost_wserialization-gcc-d-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/debug/shared-linkable-true>libboost_serialization-gcc-d-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/debug/shared-linkable-true/threading-multi>libboost_wserialization-gcc-mt-d-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/debug/shared-linkable-true/threading-multi>libboost_serialization-gcc-mt-d-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/release/shared-linkable-true>libboost_wserialization-gcc-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/release/shared-linkable-true>libboost_serialization-gcc-1_35.so... ...skipped <@boost!libs!serialization!build/libboost_wserialization.so/gcc/release/shared-linkable-true/threading-multi>libboost_wserialization-gcc-mt-1_35.so for lack of <@boost!libs!serialization!build/libboost_serialization.so/gcc/release/shared-linkable-true/threading-multi>libboost_serialization-gcc-mt-1_35.so... ...failed updating 4 targets... ...skipped 4 targets...

[boost-users] [parameter] test\preprocessor.cpp
by Cromwell Enage 01 Jun '06

01 Jun '06

With the latest CVS, test\preprocessor.cpp no longer compiles. The first two errors are: macro BOOST_PARAMETER_FOR_EACH_pred_aux3 requires 3 arguments, but only 2 given macro BOOST_PP_SPLIT_0 requires 2 arguments, but only 1 given All of my programs that use BOOST_PARAMETER_FUNCTION et al. are failing due to these errors.
