by Marshall Clow 22 Jul '14

22 Jul '14

Boost release 1.56.0 beta 1 is now available from SourceForge See http://sourceforge.net/projects/boost/files/boost/1.56.0.beta.1/ This release contains 2 new libraries: * Align: Memory alignment functions, allocators, and adaptors, from Glen Fernandes. * Type_Index: Runtime/Compile time copyable type info, from Antony Polukhin. Modularization Boost version control has migrated to a system using git submodules. This shouldn't make too much of a difference to users, although the directory … [View More]

Building modular-boost on windows with masm32?
by Alle Meije Wink 22 Jul '14

22 Jul '14

Dear all, I have tried to build modular-boost on windows (win7 64bit) using the mingw toolset. The steps that I followed (after some trial & error) are: 1. clone boost-modular from into %home%\usr\local\boost 2. in that boost directory; type bootstrap mingw ===========output=============== Building Boost.Build engine Bootstrapping is done. To build, run: .\b2 To adjust configuration, edit 'project-config.jam'. Further information: - Command line help: .\b2 --… [View More]help - Getting started guide: http://boost.org/more/getting_started/windows.html - Boost.Build documentation: http://www.boost.org/boost-build2/doc/html/index.html ================================ 3. after apparently successful bootstrap, type b2 -a -d+2 -q --prefix=c:\users\amwink\usr\local --build-type=complete --build-dir=build toolset=gcc link=shared runtime-link=shared The output is below. So the commands cl.exe and ml.exe, which are not in mingw but can be used from the masm32 package are found, but their output is not recognised (as I understand) Is that correct? Would there be a way around this other than installing VC++? Many thanks Alle Meije ===========output=============== Building the Boost C++ Libraries.

[odeint] optional data
by Erik Schultheis 22 Jul '14

22 Jul '14

Dear all, i am simulating particle trajectories, and depending on the data i want to generate i may or may not have to track additional data [boost.ublas c_matrix] along those trajectories. Right now i enable/disable that via a template parameter (so, using std::tuple(vec, vec) or tuple(vec, vec, c_matrix) and fusion_algebra), which has a few drawbacks. The algorithm is already templated to support varying dimensions via a template parameter, so the additional data practically doubles … [View More]

I did a quick test on defer and checking the queue size and it didnt work may be there is something wrong in my test program but wanted to check if anyone tried this out. thank you -raj

Push-Relabel undirected graph
by Charles Maske 20 Jul '14

20 Jul '14

Hi there, I'm working in a cut-tree implementation of gomoryhu algorithm and I have to compute max-flow on the input graph. I read about efficiency of the push-relabel algorithm and I want to do some tests but I can't get this because all reverse edges have to capacity equals 0. Someone knows one way to workaround this restriction? Other max-flow algorithms in BGL (edmonds-karp and boykov-kolmogorov) don't have this restriction, what do them more fast than push-relabel implementation. Thanks

Hello, I try to benchmark different queue implementations. I have a test program which includes the boost lockfree queue and some custom implementations where one is using gcc's STM. In order to compile it, I need to add the -fgnu-tm flag. I am using an up-to-date arch linux system with gcc 4.9.0 and boost 1.55.0 When adding this flag, I get a compilation error.

Hello, I just recently found Boost, and I am attempting to use it in a project I am working on. However, in my attempts to make simple graphs with the graph/adjacency_list.hpp subdirectory, I get a compiler error within the code for adjacency_list.hpp. I don't know if I can copy the error message correctly, but the errors seem centered around lines 1503-1505, those saying typedef typename lookup_one_property<vertex_property_type, vertex_bundle_t>::type … [View More]

Intrusive: Checking for undefined behaviour
by Brian Wood 15 Jul '14

15 Jul '14

I was reading here about some of the sanitizers http://cplusplusmusings.wordpress.com/ and decided to try it out the undefined behavior sanitizer on some code. One thing that came out was related to the Intrusive library. /home/brian/boost_1_55_0/boost/intrusive/detail/tree_node.hpp:164:44: runtime error: member access within null pointer of type 'const boost::intrusive::bhtraits<myString, boost::intrusive::rbtree_node_traits<void *, false>, 2, boost::intrusive::default_tag, 3>' … [View More]

TCP resolver creates TppWorkerThreads on windows only
by Chris Stankevitz 14 Jul '14

14 Jul '14

Hello, When I run the following code on windows, some threads are created, presumably by winsock. These threads are "named" _TppWorkerThread. This does not happen on linux. These threads do not stop when all the boost objects go out of scope, but I wish they did. Q1: Am I doing something wrong? Q2: Is there a boost way for me to stop these threads? Thank you, Chris int main() { { boost::asio::io_service DummyIoService; boost::asio::ip::tcp::resolver Resolver(DummyIoService); … [View More]

Dear All, I already posted on the boost.test user mailing list, but as my question was to technical they forward me their ( http://lists.boost.org/boost-testing/2014/07/7692.php ) I installed/compiled boost on the BG/Q (with gcc provided by IBM) but I am confronted to a issue, the framework crashed (compute node) due to a call to the system function sigaltstack. >From my previous post, a boost user suggests me to disable a macro into execution_monitor.ipp line 176 https://github.com/… [View More]boostorg/test/blob/boost-1.55.0/include/boost/test/impl/… If I disable this macro the framework works well.

hi, I used the following piece of code after following your suggestions. Iam new to boost and even multi-threading When I ran this piece of code on my machine I found that for every run 4 threads are only used out of the pool. As I have 4 cores in my machine.

Hello, I'm not 100% positive, I downloaded stale source and/or binary build of boost 1.55, supposedly, but I am finding that tickets which were reported to have been included in that version are not in the build. I'll retrace my steps to find where that build came from, but I seriously question whether this build included the latest 1.55 code. i.e. uuid fixes, which I am finding are still happening in the download: Error 1 error C4996: 'std::_Swap_ranges': Function call with … [View More]
