[Serialization] test_exported_*_archive failures
by Sohail Somani 24 Mar '08

24 Mar '08

On trunk, revision 43795. Does anyone know why these are failing? These are the only tests failing on my machine (g++ 4.1.3 on 32-bit Linux). Additionally test_*_dll don't seem to be running either... Anyway, the error I see is: ../libs/serialization/test/test_tools.hpp(182): unregistered void cast in function 'int main(int, char**)' >From a quick inspection, it appears that the cast between base and derived never gets registered. I'm actually unsure as to how the void cast can get registered *before* BOOST_SERIALIZATION_BASE_OBJECT_NVP(Base) gets executed and therefore, I'm not sure how these tests are passing anywhere else. Where/when is the Base<->Derived cast supposed to be registered in test_exported.cpp? I can only see it being registered when serialize is called for the first time on the polymorphic_derived[12]. -- Sohail Somani http://uint32t.blogspot.com

Feel free to contradict me and change > it back Dave, While we aren't really targeting VC++ 9.0 with this release, most of the problems being turned up have relatively easy fixes so I'd like to get them in 1.35.0 if doing so does not result in a delay. Thus if this one really is easy, and if someone will try the changes and walk them through the process in the next day or two, I'd like to see the fix in 1.35.0. Otherwise it can wait 'til the next release. --Beman > > > -- > Ticket URL: <http://svn.boost.org/trac/boost/ticket/1697#comment:1> > Boost C++ Libraries <http://www.boost.org/> > Boost provides free peer-reviewed portable C++ source libraries.

problem with shared_from_this in trunk
by Tim Blechmann 24 Mar '08

24 Mar '08

hi all, a few days ago, some changes to the shared_from_this implementation have been committed to the trunk ... the changes break the following code, though (maybe this can be added to the shared_from_this_test.cpp test suite?): struct V: public boost::enable_shared_from_this<V> {}; struct W: V {}; void test4(void) { W * w = new W(); boost::shared_ptr<W> p(w); } best, tim -- tim(a)klingt.org http://tim.klingt.org Most of the trouble in this world has been caused by folks who can't mind their own business, because they have no business of their own to mind, any more than a smallpox virus has.

[serialization] missing #include in test_static_warning.cpp
by Boris Gubenko 24 Mar '08

24 Mar '08

test_static_warning.cpp uses EXIT_SUCCESS without #include'ing <stdlib.h>/<cstdlib>. Because of this, the test fails to compile on HP-UX/ia64/gcc. Thanks, Boris

[GSoC 2008] Special Function and Integral Transformation Library
by Barco You 24 Mar '08

24 Mar '08

Hello, I'm a student of HUST in China, named Barco You. I think we should have a general integral (or accumulative for discrete problem) transformation library, just as we have Matrix with relevant algorithms which could be dedicated to applications. My idea is that we should construct a general transformation model continuous and discrete, and the model can be instantiated for varieties of transform kernel. The transform kernel can be for: Fourier Transform (continuous and discrete) Windowed Fourier Transform Laplace Transform Wavelet Transform Gaussian Transform Z Transform .... For doing the transforms we surely need some special functions, so a special function library should also be included. Feedback, suggestion and critique are appreciated. ------------------------------- Enjoy life! Barco You

Linker warnings
by Robert Dailey 24 Mar '08

24 Mar '08

Hi, I'm currently building a static library in Visual Studio 2008 using Boost 1.34.1. This static library is for my own personal game engine, which internally also uses several parts of boost. Two in particular I'm using is Boost.Signals and Boost.Python. I like for my static library to link in the boost libraries so that every project that uses my engine won't have to include those libraries manually. However, I find that by doing so I get tons of linker warnings when building my static library. One of which is below: "boost_signals-mt-gd.lib(boost_signals-mt-gd.dll) : warning LNK4006: __NULL_IMPORT_DESCRIPTOR already defined in boost_python_debug.lib(boost_python_debug.dll); second definition ignored" When I'm linking both of these libraries together during an executable build, I do not get these warnings. I don't understand why I'm getting these warnings in a static lib but not an executable when I'm including the very same libraries together. Any tips to resolve the warnings? Thanks.

[statechart] priority_scheduler<> status
by Manuel Jung 24 Mar '08

24 Mar '08

Hi, I would really like to use a priority_scheduler<> in the statechart library. It is on the todo list of boost 1.34.1. How about its development status? Is it in development or hast someone his own homebrew solution for a finite state machine with a priority scheduled event dispatcher? At the moment i'm using the nice ordered Multi_Index_Container to implement a priority queue. Ideas? Kind Regards Manuel Jung

JSON Archives for Boost.serialization
by Kasun Indrasiri 24 Mar '08

24 Mar '08

Hi all, I'm interested in the Boost JSON archive for Boost.serialization project which is presented in the GSoC2008. I have had good exposure to C/C++ during my academic life and projects in the past. The main motivation to select the JSON archive project is that I have developed a JSON parser for Apache AXIS2/C web service engine and I successfully completed the project. In that case the parser was written in C but the task was similar to the requirements of the Boost.serialization. Therefore I would like to contribute to the Boost C++ community through my project. I would like to gain the experience of the Boost.serialization and spirit as a preparation to the project and it would be a great experience to work with boost C++. I also a fan of open source software and currently, an active contributor(Non-Committer) to *Apache Axis2/C and Apache Rampart/C*. I would like to share my ideas through the Boost mailing lists. *As an initial step I went through the Boost Spirit and Serialization and gain the basic knowledge of those things. Currently I do have a pretty simple question that in the JSON Archives do we have to worry about the relevant XML mapping criteria (Badgerfish or Mapped) because JSON may use as an alternative to XML. And also there are few areas that JSON is really lack in supporting some requirements (basically in as an alternative to XML) of the real world applications.* Thanks. Kasun Indrasiri.
