What is the official stance on CMake adoption? Is if simply a fork in the development, or will all of Boost eventually be built using CMake? Michael

Let me just say that the book is excellent! Thanks, Boris, for supplying such a comprehensive source of information on Boost.

The German language edition is a bit more up-to-date after the English language edition has been published in September last year.

Boost.Cgi Status
by Michael Ainsworth 01 May '15

01 May '15

What is the status of Boost.Cgi by Darren Garvey? It seems that the library hasn't been accepted and it's now 2015 - at least 7 years after last Boost Users mailing list post regarding its status. Michael

[Pyhton] (re)binding class instance in python object
by Tamas.Ruszkai＠leica-geosystems.com 27 Apr '15

27 Apr '15

Hi, I have a plain C++ class which I want to exposed to python. The pyhton object accesses the C++ class via smart pointer. class Sensor : public boost::enable_shared_from_this<Sensor> { public: Sensor(int port); ~Sensor() void Open(); void SendCommand(const std::string& command); void Close(); private: int _port; }; auto sensorClassTypeObject = boost::python::class_<Sensor, boost:: shared_ptr<Sensor>>("Sensor", boost::python::init<int>()) .def("Open", &Sensor::Open) .def("SendCommand", &Sensor::SendCommand) .def("Close", &Sensor::Close); The question is: if I already have one instance of the C++ class (in a dependency injection container) then how can I create in the C++ part an instance of the python wrapper so that it does not create a new instance of Sensor, but uses my existing Sensor instance? Then I would put this instance into one of the python modules (this part would be made in C++) inside the python interpreter to be able to access it via script. Something like that: shared_ptr<Sensor> sensorInstance = DIContainer.Resolve<Sensor>(); boost::object pythonInstance = sensorClassTypeObject(sensorInstance); pythonInterpreterWrapper.AddToModule("__main__", pythonInstance); Best Regards, Tamas

[msm] Event does not get processed after exiting an interrupt state
by Chrisopher Vogl 27 Apr '15

27 Apr '15

Hi all! I got a state machine with 2 regions. The second region has two states ("Run" and "Interrupt"), one is an interrupt state. The region starts in the non interrupt state, just like in the MSM example "Orthogonal regions, terminate state, event deferring". The event called Ev_Resume leads to a transition from state Interrupt back to state Run. In on_entry() of Run I fire an event which never gets processed. Is at that time the FSM still interrupted, i.e. event processing still blocked? Christopher

Re: [Boost-users] [boost] [test] boost.test owner unresponsive to persistent problems for multiple years

It is indeed really deplorable that we don't have Boost.Test updates in a release. Though in mitigation I note that we are really struggling to get out a GIT-driven release at all, (and some of the new troubles are with asynch-exceptions in Boost.Test. See this thread Re: [boost] Running b2 on develop needs asynch-exceptions=on.) However, Richard's hard work on improved docs have been refined and completed by Raffi Enficiaud. Many bug fixes are in the develop branch (including some very new and prompt bug fixes, for example https://svn.boost.org/trac/boost/ticket/11054) I also understand that the fear of Boost.Test updates causing trouble with other libraries, and worse with users test, is a cause for caution in a release version. So it would be really good if *lots more users could download and use the version in the Boost.Test develop branch* so we can get current user feedback. (My experience is good using this, and the test matrix is also good). You can download just Boost.Test either using GIT or as a zip from https://github.com/boostorg/test/tree/develop and substitute it for the contents of the current release modular-boost/libs/test folder (Don't forget to rebuild the Boost.Test library unless you only use the included version). If nothing else, you will find Raffi's shiny new Boostbook docs finally allow you to find what you want to know without frustration. I'd very much like to see this new docs version in the 1.58 documentation release (despite any new features not being in the code release). Paul --- Paul A.

[log] Possible to explicitly disable AVX2?
by Jason Roehm 24 Apr '15

24 Apr '15

I am building Boost.Log on a relatively new machine whose compiler and CPU both support the AVX2 instruction set. Boost.Log detects this at build time and configures its compiler flags accordingly to use the AVX2 instruction set. I'd like to use the resulting binaries, however, on older systems that do not have AVX2 support. Is it possible to explicitly disable this at build time? I didn't see any mention of it in the documentation, and my attempts to parse the Jamfile's intentions were not successful. Thank you. Jason
