mapped_region locks on multithread
by Mikhail Eremin 09 Jun '12

09 Jun '12

Hello, SETTING: - There is an application, written using Boost Template library, meant for QUICK processing of bulk text files (cca 50-100Gb each). - There is a huge, quick and expensive piece of hardware with HUGE amount of RAM and multiple CPU. - There is [theoretically] any possible UNIX-like OS, even Microsoft Windows (R) is considered. - Boost Thread Pool extension is used; previously memory mapped files through memory_segment have been used, now got rid of the entire Boost::interprocess. - There are NO explicit data items in the application's algorithm to be shared by threads, each has its own piece of input file, thus - there is NO explicit concurrency. PROBLEM: - Ensure fast processing without locks and threads sleeping. Currently the threads sleep on some internal mutex. We thought it's been boost::interprocess (specifically - mmap, wrapped by a mutex), but it apparently isn't so. SPECIFIC QUESTION: - How could we get rid of Boost locks? Mike

define multi dimension array at run time
by Moataz Elmasry 08 Jun '12

08 Jun '12

Hello list I'm writing an n-dimensional histogram class and would like to use the boost multidimension array to store the elements of the histogram So the array is defined as a class member but is first initialized through the constructor, but according to boost example page its something like: typedef boost::multi_array<double, 3> array_type; but I'd like: typedef boost::multi_array<std::vector<MyObject>, n> array_type; where n is given through the constructor Is this somehow possible?

Building PDF with Open Source Solution
by Christian Henning 08 Jun '12

08 Jun '12

Hi there, This is slightly off topic. I have a question how pdf's are build within the boost build system. As far as I could figure it out the build system uses a proprietary solution called RenderX XEP or so. I'm wondering if there are open source solutions out there that could be used to generate boost's documentation as pdf files? Thanks, Christian

[serialization] custom allocation/deletion
by Brian Budge 07 Jun '12

07 Jun '12

Hi all - Is there a way to use custom allocation while loading from an archive? I'm thinking like passing an allocator along with the archive during deserialization? Adding to this, is it possible to add a custom deleter to a shared_ptr during deserialization? I am thinking of using this with boost mpi, and if I send a shared_ptr over the wire with some kind of deleter, the same deleter object can't be used on the other side since it's in a different address space. Thanks, Brian

[pool] Questions about memory pool
by Junchao Zhang 07 Jun '12

07 Jun '12

Hello, I'm new to boost memory pool. I have two questions: 1) My program has multiple iterations. In each iteration, I need to allocate chunks(objects) from a pool. I don't need to allocate array of chunks. I don't free objects until the end of an iteration. Then what is the most efficient way to do that? I wrote the following code, but I'm not sure it is right. boost::pool<> p(sizeof(MyType)); for (...) { ... // many calls to p.malloc(); ... p.release_memory(); // Is it OK??? } Also, I was wondering, to improve locality, how to reuse the memory in the next iteration, instead of deallocating/allocating memory again and again. 2) How to inquiry a pool to know have many objects have been allocated from the pool? For example, if malloc() 2 times, free() 1 time, then the count is 1. Does boost pool have this interface? Thanks! -- Junchao Zhang

[Boost.Random] Discrete distribution behavior
by sguazt 05 Jun '12

05 Jun '12

Dear Booster, I have a problem in understanding how the boost::random::discrete_distribution works. As far as I know, given the following events: x1, x2 and x2 and weights: 1, 4, and 5, * the associated PDF of the discrete distribution would be: \Pr{X=x1}=1/10 \Pr{X=x2}=4/10 \Pr{X=x3}=5/10 * and the CDF would be: \Pr{X<=x1}=1/10 \Pr{X<=x2}=5/10 \Pr{X<=x3}=1 So, if my random generator generates the value 0.814724, the discrete random variate would return the event x3 (if I'm not wrong). Instead, it seems that boost::random::discrete_distribution does not work in this way. To test it I have implemented a small program (see attachment). Moreover, I have also implemented a naive version of discrete distribution (called my::discrete_distribution), which simply draws a uniform [0,1] random number and select the first event whose CDF is greater than or equal to the drawn value. I have also added some debug prints in other boost classes (just to get the value of the generated random numbers). I run it in Linux with Boost devel version + GCC 4.6.3 (with flags: -Wall -ansi -pedantic) Here's the output: Testing Boost... [boost::random::mersenne_twister] 3499211612 [boost::random::mersenne_twister] 581869302 [boost::random::discrete_distribution] test=0.814724 - result=0 Random Event: 1 [boost::random::mersenne_twister] 3890346734 [boost::random::mersenne_twister] 3586334585 [boost::random::discrete_distribution] test=0.905792 - result=2 Random Event: 2 [boost::random::mersenne_twister] 545404204 [boost::random::mersenne_twister] 4161255391 [boost::random::discrete_distribution] test=0.126987 - result=2 Random Event: 2 Testing My own version... [boost::random::mersenne_twister] 3499211612 [my::discrete_distribution::rand] RNG: 0.814724 Random Event: 2 [boost::random::mersenne_twister] 581869302 [my::discrete_distribution::rand] RNG: 0.135477 Random Event: 1 [boost::random::mersenne_twister] 3890346734 [my::discrete_distribution::rand] RNG: 0.905792 Random Event: 2 As you can see, the sequence of Random Event is different. Looking at the output of my::distribution, it seems it is working OK. Can you help me in understanding what is going on? Thank you very much for the help!! Best, -- Marco

Hi, I like to collects some stats. There are several data slices where I can partially/separated collect them (each of them). Finaly I like to combine these stats to a single one to get summarized informations. How to? May this work: accumulator_set<..> acc1; accumulator_set<..> acc2; ... accumulator_set<..> acc_all; ... acc1(42); ... acc_all += acc1; ... acc_all += acc2; Because did not found informations about. The same problem woulde be probably for a threaded implementation too. Thanks, Olaf

[multi_array] operator= requires resize - why?
by Markus Werle 04 Jun '12

04 Jun '12

Hi! IMHO the behaviour of operator= for multi_array is a little bit broken. A lot of preconditions required: template <typename ConstMultiArray> multi_array_ref& operator=(const ConstMultiArray& other) { [...] // make sure the dimensions agree assert(other.num_dimensions() == this->num_dimensions()); assert(std::equal(other.shape(),other.shape()+this->num_dimensions(), this->shape())); Besides the fact that I get mad about asserts instead of exceptions (please change this to a way users may choose) why do we have such an odd behaviour here? >From page 1, line 3 of the docs I cite: "The interface design is in line with the precedent set by the C++ Standard Library containers" - this is not true for operator=, since std::<container>::operator= works fine for me all the time _without_ any resize. Could we please change the behaviour of multi_array::operator= to take care of resize where in need to? IMHO operator= should result in a true copy ignoring previous state. Markus

Boost logger parameters.
by Mangesh Sawant 04 Jun '12

04 Jun '12

When I use boost for asynchrous logging, application crashes due to low memory. It seems internal queue maintained by boost during asynch logging is causing this problem. Is there any way to limit size of internal queue, during asynch logging. If I switch to synchronous logging there is no crash. Thanks, Mangesh Sawant.

Hi , Using boost logger for asynchronous logging. Application crashes with bas_alloc exception. When I switch to synchronous logging mode there is no crash. It seems in asynchronous mode log queue size keeps growing leading to low memory. Is there any way(i.e a parameter in setting file) to control max log queue size in asynchronous logging. Thanks, Mangesh Sawant.

[boost] [review] Multiprecision review scheduled for June 8th - 17th, 2012
by Jeffrey Lee Hellrung, Jr. 04 Jun '12

04 Jun '12

Hi all, The review of the proposed Boost.Multiprecision library authored by John Maddock and Christopher Kormanyos has been scheduled for June 8th - June 17th, 2012 and will be managed by myself. >From the Introduction: -------- "The Multiprecision Library provides *User-defined* integer, rational and floating-point C++ types which try to emulate as closely as practicable the C++ built-in types, but provide for more range and precision. Depending upon the number type, precision may be arbitrarily large (limited only by available memory), fixed at compile time values, for example 50 decimal digits, or a variable controlled at run-time by member functions. The types are expression-template-enabled for better performance than naive user-defined types." -------- And from the original formal review request from John: -------- Features: * Expression template enabled front end. * Support for Integer, Rational and Floating Point types. Supported Integer backends: * GMP. * Libtommath. * cpp_int. cpp_int is an all C++ Boost licensed backend, supports both arbitrary precision types (with Allocator support), and signed and unsigned fixed precision types (with no memory allocation). There are also some integer specific functions - for Miller Rabin testing, bit fiddling, random numbers. Plus interoperability with Boost.Rational (though that loses the expression template frontend). Supported Rational Backends: * GMP * libtommath * cpp_int (as above) Supported Floating point backends: * GMP * MPFR * cpp_dec_float cpp_dec_float is an all C++ Boost licensed type, adapted from Christopher Kormanyos' e_float code (published in TOMS last year). All the floating point types, have full std lib support (cos sin exp, pow etc), as well as full interoperability with Boost.Math. There's nothing in principal to prevent extension to complex numbers and interval arithmetic types (plus any other number types I've forgotten!), but I've run out of energy for now ;-) Code is in the sandbox under /big_number/. Docs can be viewed online here: http://svn.boost.org/svn/boost/sandbox/big_number/libs/multiprecision/doc/h… -------- I hope everyone interested can reserve some time to read through the documentation, try the code out, and post a formal review, either during the formal review window or before. I expect to conduct the review in the "traditional" manner, i.e., entirely within the regular boost developers' mailing list (boost(a)lists.boost.org) I will send a reminder of review process details closer to the review window. Thanks! - Jeff

problem with boost compilation
by Ohad Barta 01 Jun '12

01 Jun '12

Hi I installed and compiled boost for my project a long time ago, however now I fail to repeat on this success on another computer. I use only the serialization library, therefore the folder that my project linker includes in order to work properly is: C:\boost_1_47_0\boost_1_47_0\bin.v2\libs\serialization\build\msvc-10.0\release(or debug...)\address-model-64\link-static\threading-multi what is the corresponding cmd compilation command? I tried to specify all the corresponding flags but for some reason it doesn't work,(for example- despite using the flag --address-model=64, the folder "address-model-64" wasn't constructed in my folders hierarchy tree, so I guess that this flag was ignored) Thanks in advance!

asio ssl handshake error
by Lloyd 01 Jun '12

01 Jun '12

Hi, We are using SSL for secure communication. In this both the parties verify each other (ctx.set_verify_mode(boost::asio::ssl::context::verify_peer|boost::asio::ssl::context::verify_fail_if_no_peer_cert);). Both the communicating parties uses self signed certificates. Both client and server loads the each others public key for peer verification, for that we use the call ctx.load_verify_file(). At the client side when we call "load_verify_file()" only once with the other parties public key it works perfectly. If we load one more public key of some other application again using "load_verify_file()" the peer authentication fails. So what I understood is "load_verify_file()" loads only one latest certificate, but the documentation says it can be used for loading one or more CA files. To solve this, I also merged the two certificates into one file and tried loading it. If the valid certificate is in the second position in the file the verification is performed successfully. Otherwise it fails!! What could be the reason, is there any method available for peer authentication? Thanks, Lloyd

Dear friends, Please tell me how to set the pkg-config in bjam. please see,like this I am using while compiling the using gcc and make command 1) gcc -g - o `pkg-config --cflags glib-2.0 dbus-glib-1 --libs glib-2.0 dbus-glib-1` main main.c but I don't know how to add this option in bajm and also I don't know where to add this option in either jamfile or boost-build.jam, or user-config.jam. because you might get doubt why do you want use glib and dbus means I using dbus api's in my program. so how to and where to add is my big confusion , please if any one knows could help me get out of this problem. I had tried in the bellow ways but didn't worked so using gcc : : : <cxxflags>-glib-2.0 -dbus-glib-1 : <libs>-glib-2.0 -dbus-glib-1 ; using gcc : : : <compileflags>-glib-2.0 -dbus-glib-1 : <libs>-glib-2.0 -dbus-glib-1 ; some time I thought, I am adding above options in wrong place meaning different file , please any one can suggest.

BOOST PASSING PARAMETER PROBLEM

hello I have a program like the last regex program in this link: http://www.boost.org/doc/libs/1_49_0/libs/regex/doc/html/boost_regex/ref/re… inside the while loop *i++ returns the url's found with regex: while(i != j) { std::cout << *i++ << std::endl; } i need to pass *i++ to a function that "accepts" the url string/address/pointer (the function is in different c++ file) as a string (before it the function header was char** argv) how do i pass *i++ to the function in order to make it accept the *i++ parameter?

[integer_traits problem
by Robert Ramey 29 May '12

29 May '12

I'm having problems with integer traits when passed an __int64 type data type under Visual C++. I run the following test: boost::mpl::print< boost::mpl::integral_c< boost::intmax_t, boost::integer_traits<boost::intmax_t>::const_min > > x13; boost::mpl::print< boost::mpl::integral_c< boost::intmax_t, boost::integer_traits<boost::intmax_t>::const_max > > x8; What I expect to get for const_min is: ... 1> T=boost::mpl::integral_c<boost::intmax_t,0x8000000000000000> ... What I get is: 1>test_fixed_type.cpp 1>c:\boostrelease\boost\mpl\print.hpp(51) : warning C4308: negative integral constant converted to unsigned type 1> c:\projects\boost projects\safe_numerics\include\test_fixed_type.cpp(13) : see reference to class template instantiation 'boost::mpl::print<T>' being compiled 1> with 1> [ 1> T=boost::mpl::integral_c<boost::intmax_t,0x800000000> 1> ] 1>c:\boostrelease\boost\mpl\print.hpp(51) : warning C4308: negative integral constant converted to unsigned type 1> c:\projects\boost projects\safe_numerics\include\test_fixed_type.cpp(20) : see reference to class template instantiation 'boost::mpl::print<T>' being compiled 1> with 1> [ 1> T=boost::mpl::integral_c<boost::intmax_t,0x7fffffffffffffff> 1> ] That is the value for const_min is not correct !!. Note I've tried various different types such as using __int64 and also changed the rendering of he real vale to _I64_MIN. None of this seems to fix things. I've also tried making my own specialzation of integral_c for this type: template<boost::intmax_t C > struct integral_c<boost::intmax_t, C> { BOOST_STATIC_CONSTANT(boost::intmax_t, value = C); typedef integral_c_tag tag; typedef integral_c type; typedef boost::intmax_t value_type; operator boost::intmax_t() const { return this->value; } }; Hmmm now I'm wondering about BOOST_STATIC_CONSTANT. and looking at the documenation of BOOST_STATIC_CONSTANT shows it's not really expected to work on anything wider than an int. What should one do in a case like this? Robert Ramey

[ASIO]: Best solution for Publisher/Subscriber pattern
by Ingo Maindorfer 28 May '12

28 May '12

Hi All, currently we do some research in how we can do implement the classical Publisher/Subscriber pattern using ASIO. We had one thread that produces some kind of a message and like to send it out to 1 to n subscribers via TCP, where n is < 5. Message rate will be up to 800 Hz. My first idea is that the producer thread puts the message in a blocking queue. On the other end a consumer thread waits, takes the message and send it to the subscribers via synchronous or asynchronous send. One requirement is, when one connection blocks (because their client is buggy/hangs) it's ok to drop messages for that connection, but we should deliver to the other subscribers. It's also a one way communication from publisher to subscriber. Can someone provide some hints for best practices / design patterns / comments please? If I show up with some other lib like ZeroMQ my colleagues will fry me, so it's the easiest to use boost also for that task.. Best, Ingo

"invalid signature" in boost::archive::binary_iarchive
by Ibrahim Beicker 28 May '12

28 May '12

I had to port a multi-process application to 64 bits and I rely on boost serialization to send messages, that are maps of key-values, into Microsoft queues to the other modules. It works just fine into 32 bits but when I run it in 64 the constructor throws an "invalid signature" exception void Message::fromBinary( const std::string& data ) { std::stringstream ss; ss << data; boost::archive::binary_iarchive ia(ss); //exception here ia >> *this; } I managed to debug into basic_binary_iarchive.ipp and this 'if' @ line 72 fails if(file_signature != BOOST_ARCHIVE_SIGNATURE()) boost::serialization::throw_exception(archive_exception(archive_exception::invalid_signature)); inside this file I have no debug symbols so I don't know the values of 'file_signature' and 'BOOST_ARCHIVE_SIGNATURE' or where BOOST_ARCHIVE_SIGNATURE is defined. Some additional information: the modules are all running on the same machine, on windows 7 64-bits, and compiled by visual studio 2010 x64 including static boost libraries 1.45. What causes this and how can I fix it?

[asio] Using asio for asynchronous event processing
by Edward Diener 28 May '12

28 May '12

I do not understand the documentation for asio, or even if it pertains to the programming problem I am trying to solve. The doc, for whatever reason, is poor regarding practical use. But rather than complain about the doc I will ask a specific problem related to what I am trying to do and hopefully someone can help me or point me to something in the doc by which I can understand how to use asio for my problem. I need to design generalized asynchronous events triggered by an event source and handled by an event handler. The event source would trigger an event declared as a callable object, as in boost::function, and an event handler would eventually handle the event asynchronously. The event source and the event handler would be in different threads of an application but not in different applications. The event source triggers the event but does not block in any way waiting for the event to be processed. The event source may subsequently trigger other asynchronous events to be eventually handled in the same way without blocking. The event handler is able to check for events periodically from within its own thread. Each event itself could be a totally different callable object, but the event source and the event handler both know the callable prototype for any given event. The event source and the event handler are completely disconnected in that neither knows about the other. For any given asynchronous event there may be any number of event handlers when an event is triggered. Can I use asio to implement such a solution ? The doc suggests that asio does not only deal in i/o events, such as networking and sockets, but I could not understand whether it deals in generalized asynchronous operations or not. The proactor pattern is understandable but there appears to be nothing in the doc which connects the elements of the proactor pattern to classes in asio. The basic tutorial as well as the sockets tutorial does not enlighten me at all. Hopefully someone here can help.

BOOST_ALL_NO_LIB / BOOST_THREAD_NO_LIB / BOOST_THREAD_DYN_LINK etc etc etc
by Josh Quigley 28 May '12

Hi, I'm trying to link to Boost.Thread DLL's. If I define BOOST_ALL_NO_LIB everything works fine - but it wants to link all packages as DLL, instead of just Boost.Thread. None of the following cause dynamic linking - that is I get a linker error saying the static *.lib could not be found. (defined on the command line, Visual Studio 2010) BOOST_THREAD_NO_LIB BOOST_THREAD_DYN_LINK BOOST_THREAD_ALL_DYN_LINK BOOST_THREAD_BUILD_DLL BOOST_THREAD_USE_DLL Is there a problem with - what I'm doing; - Visual Studio 2010; or - boost.thread?

arm-elf-gcc 4.0.1 class alignment
by Pierre-Andre van Leeuwen 28 May '12

28 May '12

Hi Not sure if this belongs on this list or the Boost.Build list, but the problem exists when using Boost as well as building it. I'm using Boost with the ARM-ELF-GCC toolchain with gcc version 4.0.1. When building the Boost serialization library, I get the following error: ./boost/archive/basic_binary_oarchive.hpp:80: error: invalid application of 'sizeof' to incomplete type 'boost::STATIC_ASSERTION_FAILURE<false>' It turns out that sizeof(class_id_type ) == 4 in stead of 2, where class_id_type is defined as follows: class class_id_type { private: typedef int_least16_t base_type; base_type t; ... }; Using a toolchain with a more recent gcc version (arm-none-eabi-gcc 4.4.1) works correctly, but unfortunately I need to get Boost working with the old toolchain as well. I have tried to add __attribute__ ((packed)) to the class declaration, but that breaks as well (cannot bind packed field in operator int_least16_t). Is there anything I can do to rectify the situation? My user-config.jam contains the following: using gcc : armelf : "arm-elf-gcc.exe" : <cflags>-nostdlib <cxxflags>-DBOOST_NO_INTRINSIC_WCHAR_T <cxxflags>-D__OAT_API_VERSION__=637 <cxxflags>-D__WIP_PLUGIN_VERSION__=543 <cxxflags>-D__arm <cxxflags>-D_LITTLE_ENDIAN <cxxflags>-IC:\Program Files (x86)\Sierra Wireless\Embedded Software\com.wavecom.openat.ide.spm.lib.os.model.6.37.0.201202060950_6.37.0.201202060950\resources/ADL/itf <cxxflags>-IC:\Program Files (x86)\Sierra Wireless\Embedded Software\com.wavecom.openat.ide.spm.lib.os.model.6.37.0.201202060950_6.37.0.201202060950\resources/ADL/basic <cxxflags>-IC:\Program Files (x86)\Sierra Wireless\Embedded Software\com.wavecom.openat.ide.spm.lib.plugin.model.WIP.5.43.0.201202100610_5.43.0.201202100610\resources/WIP/itf <cxxflags>-fshort-enums <cxxflags>-fdollars-in-identifiers <cxxflags>-nostartfiles <cxxflags>-fno-strict-aliasing <cxxflags>-fno-common <cxxflags>-fomit-frame-pointer <cxxflags>-mthumb-interwork <cxxflags>-mthumb <cxxflags>-march=armv5te <cxxflags>-msoft-float <cxxflags>-mfpu=fpa <cxxflags>-mapcs <cxxflags>-mno-apcs-stack-check <cxxflags>-mlittle-endian <architecture>arm <address-model>32 ; I'm building boost with the following command .\b2 variant=debug,release link=static threading=single toolset=gcc-armelf --debug-configuration --debug-building --with-serialization stage Any help will be appreciated.

BOOST_RESULT_OF_USE_DECLTYPE and Boost.Optional ?
by John M. Dlugosz 27 May '12

27 May '12

I turned on BOOST_RESULT_OF_USE_DECLTYPE and used boost::result_of because the std::tr1::result_of that comes with VS10 doesn't use declspec at all and thus doesn't work right with lambda functions. This passes my unit tests, but fails on a piece of code that has a function returning an instantiation of boost::optional. It seems confused as to whether the value held in the optional is as-specified or has a reference added to it. I wonder if this is a specific issue with optional that might be addressed/worked-around/patched, or perhaps there is a way to enable declspec-based testing just for the code that wanted it and not globally? —John

Apple "Block" closures and boost::function
by John M. Dlugosz 26 May '12

26 May '12

I'm looking at using Apple's proprietary closure blocks as a substitute for C++ lambda functions on a project that needs to be portable between Mac (LLVM 3.1, but not using the C++0x dialect compiler switch) and Windows (Visual Studio 10). The project uses Boost.TR1 to supply std::tr1::function and related stuff on the Mac build. Now I found that the compiler handles the nonstandard block objects in Functor-like template situations in a manner perfectly analogous to C-style pointers to functions. I can even assign one to a boost::function with no complaint! The only issue seems to be that it never calls Block_copy/Block_release. So it works OK for passing them to STL algorithms that uses them on the spot, but will probably do bad things if used in general. Does anybody have something ready-made, to efficiently add the copy/destroy semantics to functors that hold such "blocks"? That would be much more efficient than wrapping them in another layer. Or, any pointers to the Boost innerds for doing that myself? Thanks, —John

[Test] main for BOOST_TEST_DYN_LINK with manual registration

25 May '12

What from example 15 from the Boost.Test "Manually registered test suites" documentation[1] needs to change if instead of #include <boost/test/included/unit_test.hpp> one used #define BOOST_TEST_DYN_LINK #include <boost/test/unit_test.hpp> ? >From reading [1] and [2], one needs to provide a main() that invokes the unit_test_main, but I'm at a loss for what it would look like... I don't think I'm running afoul of BOOST_TEST_ALTERNATIVE_INIT_API from reading <boost/test/unit_test.hpp> where the main() definition cares nothing about that #define, but I could be wrong.

[Geometry] spatial linestring access along line
by Stephan Menzel 25 May '12

25 May '12

Hi all, before I begin, let me tell that geometry is not exactly my strong suite so please forgive my probably dumb question. I have started to work with boost geometry which, I find very neat, and assembled a line string. Now I basically need a method that gives me a point to a length value. Like when my linestring is 100 units long and I say give me the point at 3 I want the exact position of the point (coordinates) as if I were following the line for exactly 3 units. I have an approach that would allow me to implement this myself by following the segments (possibly after indexing them) but I have a feeling that one of those many functions provided by the library itself might do just that and I simply don't know it. If anyone knows if such is the case, would be nice to give me a heads up. Thanks, Stephan

I believe that the small-buffer optimization implementation is superior to forcing the definition of a closed-set of possible type as suggested in a TODO within the ASL documentation. During my performance testing I had considerably superior performance than the ASL implementation. I wondered if you disliked my implementation, or had any feedback. Additionally I wondered what you thought about moving the Boost.Range internal any_iterator implementation into Boost.Iterator. I can't honestly imagine a good use-case for using any_iterator in preference to any_range, hence I haven't suggested this previously. This could easily be due to my lack of imagination! Can you think of a time when using an any_iterator on any interface would be superior to using an any_range? Your opinions and guidance would be much appreciated.

Iterator concept checking
by McNamara, Nate 24 May '12

24 May '12

I'm trying to learn to use BOOST_CONCEPT_CHECK for custom iterators, ranges, and containers. I've built a simple linked list class with an iterator (and const_iterator) that, as far as I can tell, satisfies the forward traversal iterator requirements.

[Chrono] Negative real time
by Wilfried Kirschenmann 23 May '12

23 May '12

Dear chrono maintainer team, Using the following example : int main(int argc, char **argv) { boost::chrono::process_real_cpu_clock::time_point start = boost::chrono::process_real_cpu_clock::now(); for ( long i = 0; i < 1000; ++i ) std::sqrt( 123.456L ); // burn some time Sleep(10000); //idle some time boost::chrono::process_real_cpu_clock::time_point end = boost::chrono::process_real_cpu_clock::now(); std::cout << end << std::endl; boost::chrono::process_real_cpu_clock::duration elapsed = (end - start); std::cout << "took real : " << elapsed << "nanoseconds\n"; return 0; } I obtain negative times. I run boost 1.49 win32 on Windows 7 x64 with Visual studio 2010. Studying the behavior of the timer, I think that the error is one of these : - process_real_cpu_clock::now() only stores the current time in a 32 bit integer instead of a 64 bit integer - time_points only prints the 32 lowest bits. I came to this conclusion by observing the results printed before they got negatives (printing in the loop with the sqrt): 2019000000 nanoseconds is the last value printed before getting negative. Is there any mistake in my way of using this chronometer ? Do you have a workaround ? Thank you for your help !

Hi! I'm using boost::serialization to save a structure to a file and read from a file. My code works perfect in debug-build, but in release-build an exception is thrown. I'm using MSVC2010 to build the project on Windows 7 64-Bit-Machine. The code is the same. Who could help me out? You can find the code here: http://boost.codepad.org/8fp6XnC3 Thank you very much!!!!

First attempt at using Boost::Test is a flop: the program ends with an exception related to std::string but I don't use any
by Ted Byers 23 May '12

23 May '12

Here is the full output from my program: $ ./decision.test.suite terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_S_construct NULL not valid Aborted (core dumped) Now, all the code in this program is focussed on number crunching, so none of it involves strings. I am guessing that I missed something in setting up a test suite. After including the headers for the function objects being tested (some of which are template classes) as well as headers for several boost libraries, I have the following: #define BOOST_TEST_MAIN decision_tests #include <boost/test/unit_test.hpp> #include <boost/test/floating_point_comparison.hpp> BOOST_AUTO_TEST_SUITE( test_decisions ) BOOST_AUTO_TEST_CASE( test_dist_moments ) { And I have a series of test cases that start the same way. After setting up the required data for each test, I use something like: BOOST_CHECK_CLOSE( Sm, 0.00000000000, 0.0001 ); or something like: BOOST_CHECK(ibll(x1,i) == true); Of course each test case ends with a closing '}' and the whole program ends with: BOOST_AUTO_TEST_SUITE_END() Now, I know I can write a suite of unit tests without using Boost::Test, but I was hoping I'd just missed something obvious. I don't even know where to look for the cause of this exception since none of the code I actually wrote that is involved in these tests makes any use at all of any strings. My guess is that I must have missed some macro required by the unit test framework that is required in order to ensure whatever string object is involved in this exception doesn't get a NULL value. Or maybe I missed a header. I really have no idea where to look for the cause of this problem. Any guidance on what to look for or what I may have missed, would be greatly appreciated. Cheers Ted

boost::signals2::signal - is a "decimated" version available?
by Chris Stankevitz 22 May '12

22 May '12

Hi, I'm using boost::signals2::signal to notify a dialog when the state of an underlying object has changed. The signal is sometimes is generated at 100Hz. Other times it is generated at 1Hz. The dialog provides a "slot" for this signal that updates the controls on the screen. I'd like to limit the "slot rate" to 10Hz. By "slot rate" I mean the rate at which the slot receives notification from the signal. This will prevent the screen updates from happening faster than can be seen. Has this been done already? If not, I'm going to implement something like the pseudocode below. Currently I'm not sure how I to specify "arguments" nor how I am going to specify the function "SlotCallback". Thank you, Chris === Pseudocode: float MaxPeriod = 0.001; // 10Hz class SignalDecimator { public: void Register(signal Signal, slot Slot) { Signal.connect(&SignalDecimator::SlotCallback, this, _1, _2, _3, _4...); mSlot = Slot; } private: void SlotCallback(arguments Arguments) { if (TimeSinceLastCall() > MaxPeriod) { mSlot(Arguments); } else { mArguments = Arguments; if (!TimerIsRunning()) { StartTimer(MaxPeriod - TimeSinceLastCall()); } } } void TimerCallback() { mSlot(mArguments); } slot mSlot; timer mTimer; arguments mArguments; }

Hello, It appears that the implementation of mapped_file in iostreams does have a resize method, but it isn't documented. If I'm going to be resizing a mapped_file_sink, are there any issues I need to be aware of? Particularly around the use of iterators. Thanks.

Rational: [PATCH] Eliminate excessive calls to gcd and add operator%
by Mario Lang 22 May '12

22 May '12

Hi. I am using boost/rational.hpp in my code to represent musical time with rational numbers. I have found some possible improvements. These improvements have accumulated into a small patch which I'd like to present for review. I think it is worth applying. There doesn't appear to be a maintainer for rational.hpp though, so I am writing to the list. The story: In my application I need a remainder operation. Looking at rational.hpp and its work-horse operators.hpp it became rather obvious that rational.hpp can and (in my opinion) should implement operator%= and friends. operator%= can easily be defined as return operator-= (other * rational_cast<int_type>(*this / other)); I have been using this definition for operator%= successfully in my code for quite a while. During a profiling session it showed up which made me think a bit more. Actually, the current way how rational.hpp implements mixed-mode operators is a waste of performance. It calls the corresponding operator with a temporary rational where the denominator is always equal to 1. However, this means that there are excessive (unnecessary) calls to boost::math::gcd performed by the operators. For instance, addition of two rational numbers needs two calls to gcd. On the other hand, addition of a rational number and an integer can be performed without any gcd at all (n += d * i). Similarily, multiplication of two rational numbers needs two calls to gcd, while multiplication of a rational with an integer only needs one call to gcd. So it is definitely worth it to actually define the mixed mode operators not in terms of the already existing operators but reimplement them with the unnecessary calls to gcd removed. After this, the definition of operator%=(const rational&) results in one less call to gcd (because there is one mixed-mode multiplication involved) and the definition of operator%=(param_type) saves two unnecessary calls to gcd since there is one mixed-mode multiplication and one mixed-mode division involved. Obviously, all code that involves mixed-mode operators benefits from these changes. As a side effect of reading code I noticed that the definition of operator=(param_type) (assign from an integer) also does unnecessary gcd. It currently calls assign(n, 1) which itself calls normalize() which does gcd. However, as above, we know that there is no need to calculate gcd of (n, 1) since it will always be 1. So I changed the definition of operator=(param_type) to directly assign the parameter to num and set den to 1, instead of calling assign(). Another useless call of gcd squashed! On top of these, we can observe that now that boost::rational provides operator%= it is actually an instance of ordered_euclidean_ring_operators. Comments and committers welcome.

Problem compiling with boost thread
by Rajalakshmi Iyer 21 May '12

21 May '12

Hello, I am trying to compile my application with Boost thread library (1.49.0) on Ubuntu 11.10 (gcc 4.6.1). However I see this error: $(BOOST_PATH)/include/boost/thread/detail/config.hpp:29:24: fatal error: platform.hpp: No such file or directory compilation terminated. In the file $(BOOST_PATH)/include/boost/thread/detail/config.hpp, the platform.hpp is included as: #include "platform.hpp" If I change that to: #include <boost/thread/detail/platform.hpp> this error goes away. However, there are a lot of places where headers are included using relative path, thereby causing compilation errors. Is there a workaround for this?

Hi, John. > Many thanks for any help. I'm really enjoying Asio and other parts of Boost, but I still don't > understand the framework completely. Sorry, if I'm spamming you but feel free to read Asio examples at my project - http://sourceforge.net/projects/asio-samples.

Yes, you need to close all sockets (and other instances of asio::basic_io_object) having pending asynchronous operations (read/write for sockets, async_wait for timers, etc), related to the used instance of asio::io_service. Otherwise you can call asio::io_service::stop(). > I added 2 member functions to help me: > > void chat_server::close() > { > ? room_.close(); > } > > void chat_room::close() > { > ? std::for_each( participants_.begin(), participants_.end(), boost::bind(&chat_room::leave, this, _1) > ); > } > > I call this in my server app class's destructor before calling thread_group::join_all, but this has a > crash.

Deriving custom archive classes from boost::archive::text_oarchive_impl and boost::archive::text_iarchive_impl
by Aldo Longhi 21 May '12

21 May '12

*Note: Boost's archive scheme is based on symmetrical input and output archive classes. It's tedious to write about both of them all the time, so I'll use "?archive" to mean both "oarchive" and "iarchive".* *Summary:* After changing the base classes of my custom archives from binary_?archive_impl to text_?archive_impl, my custom archive classes are no longer "found" when the compiler is instantiating the serialize(...) methods in my other classes. *Background:* My application was successfully reading and writing files to disk using subclasses of binary_?archive_impl (the documentation and/or code comments recommend this over deriving from binary_oarchive). I needed to switch from a binary file format to a text format, so I switched the base classes of my custom archives to text_?archive_impl. That's when everything blew up. *The problem:* My custom archive classes add functionality, including some additional methods which do not exist in their Boost base classes; these methods are called in the serialize(...) methods in many of my classes, and they were working fine. After changing the base classes from binary_?archive_impl to text_?archive_impl, I received compilation errors all over the place complaining that my custom methods do not exist in text_?archive. Well, that's obvious (!!!), but they DO exist in my CUSTOM archives, and they were working JUST FINE when I was using Boost's binary base classes. What's the deal? *What I found, and my temporary - but undesirable - solution:* After tearing my hair out and going around in circles for about a day, this is what I found... 1) Some time ago (Boost 1.34 I believe), the files "binary_?archive.hpp" were split up into "binary_?archive_impl.hpp" and "binary_?archive.hpp" (the latter #include the former). This WAS NOT done to "text_?archive.hpp". (As a result, I changed my application's #include lines from "binary_?archive_impl.hpp" to simply "text_?archive.hpp".) 2) If I split up "text_?archive.hpp" into two parts and #include only the "..._impl.hpp" headers, everything works. (But I really DON'T want to modify my Boost installation!) 3) Looking more closely at these headers and fiddling around a bit, I found that if I use the original, unmodified headers and comment out the line BOOST_SERIALIZATION_REGISTER_ARCHIVE(boost::archive::text_oarchive) (and likewise for text_iarchive), then everything works fine again. (By the way I have similar lines in my own archive code to "register" my custom archives.) *The mystery, and my dilemma:* A) Why does the presence of those lines foul up the works? ...and why does removing them make things work? ...and what might I have broken (without knowing it) by doing so? B) Why were the "text_?archive.hpp" files NOT split up along with the "binary_?archive.hpp" files a long time ago? (Is the library broken? Should it be fixed?) C) Is there any way to solve this in my application code WITHOUT modifying my Boost installation? *P.S. I'm using Boost 1.48 and Visual Studio 2010 SP1 (64-bit)*

[asio] Correct handler signature for io_service::post/dispatch
by Gary Sanders 20 May '12

20 May '12

Currently I'm developing a server that uses Boost.Asio, version 1.49. It makes use of io_service::post and io_service::dispatch to invoke handlers running in the same process, but on different threads. Some of the handlers invoke a function with the following signature: void handler(std::string s); This works fine and no problems have been observed. However, subsequently I read in the asio documentation that the function signature of a handler invoked by post/dispatch *must* be in the following format: void handler(); Is my code working by chance or is the asio version 1.49 documentation out of date? Regards Gary Sanders

asio - improving chat server example for my usage
by john grant 18 May '12

18 May '12

Hi,I could use some help to build on Asio's chat_server example so I can use it in my app. I want the server to have a main thread loop, like you would need if the server had a user interface or some other responsibility than just accepting client connections and echo-ing their input. I added a thread_group to call 'io_service::run' (to allow for asynchronous connections), letting the server have a main app loop for other responsibilities. I've learned enough about Asio by watching and reading Michael Caisse's excellent Asio presentation from BoostCon 2010 to feel somewhat comfortable using Asio and Threads together. I have a client app that connects well with the server app. ** I have a problem with my server app upon shutdown. The problem is that the thread_group I am using is stuck at the 'join_all' call (in the server app class's destructor). ** 1- I was worried that the threads were all dead, so I added a work object to my server app class, and now I delete it before I call 'join_all', but it still hangs here. 2- This might be way off, but I also wondered if I need to close all the sockets so that the thread group could join. I added 2 member functions to help me: void chat_server::close() { room_.close(); } void chat_room::close() { std::for_each( participants_.begin(), participants_.end(), boost::bind(&chat_room::leave, this, _1) ); } I call this in my server app class's destructor before calling thread_group::join_all, but this has a crash. The crash occurs right after chat_room::close() completes. I'm not confident in the way I used bind(...), but I was able to see the function execute, and then the crash occurs later. ** Do you know what I am doing wrong that causes the thread_group to hang? If I need to close the sockets, can you show me how to do that so I do not crash my app? ** For additional context, my server needs to send vehicle state to clients, among other messages. The server has a real time physics simulation. My client app will show a representation of the physics simulation. Many thanks for any help. I'm really enjoying Asio and other parts of Boost, but I still don't understand the framework completely. By the way, the IRC channel has been a big help already, but it seems everyone is busy in Aspen. :) John

[bimap] How to erase a single association in a many-to-many bimap?

Hi, I have a bimap typedef bimap< multiset_of< tagged< Person*, consultant> >, multiset_of< tagged< Company*, client> >, with_info< tagged< ConsultancyContract*, contract> > > Consultancy; initialized as follows Consultancy consultancy; Person John("John"), Jane("Jane"); Company Dell("Dell"), HP("HP"); ConsultancyContract JohnContractD(10,1); ConsultancyContract JaneContractD(20, 2); ConsultancyContract JaneContractH(30, 3); consultancy.insert(Consultancy::value_type(&Jane, &Dell, &JaneContractD)); consultancy.insert(Consultancy::value_type(&Jane, &HP, &JaneContractH)); and I want to remove only the specific association Jane<->Dell and so I'm using consultancy.erase(Consultancy::value_type(&Jane, &Dell)); but then the resulting consultancy bimap is empty, while I expect the association Jane<->HP to be there yet. If I add before erasing consultancy.insert(Consultancy::value_type(&John, &Dell, &JohnContractD)); and then consultancy.erase(Consultancy::value_type(&Jane, &Dell)); all the associations concerning Jane are removed. What I'm doing wrong? How to erase a single association? Best, Vicente

segmentation fault using boost asio in linux.

Hi, I am using Boost Asio and hitting a segmentation fault crash in ubuntu. I don't have any issue when this is run in the windows. it runs and after half an hour, it hits this crash. Below is the code that starts from beginning to the place that the segmentation fault happened. The interesting part is that I use io_strand all over the code and I don't see any thread-safety issue. In the program I use 2 threads that run the worker io_servece.run(). I also put some printf in the HandleSend() just before the crash. i can see that itr pointer is not valid even though m_pending_sends has one element in the list that is supposed to be this itr pointer.

[boost] [decimal] Proposed portable implementation ofstd::decimal
by Josh Quigley 16 May '12

16 May '12

Hi all. A first draft of this library is available at https://sourceforge.net/projects/stddecimal/ Runs on MSVC10 and gcc 4.6.3. Wraps the Intel implementation only, Until we resolve the licencing issue, top-level README contains detailed instructions about where to get 3rd party code and what to do with it. I'm keen on feedback on a particular point (although all feedback is of course welcome!): The current project can parse and execute the test cases maintained by Mike Cowlishaw from http://speleotrove.com/decimal/ (referred to as the Test Cases). To be completely clear, I also have normal, interface testing test cases, I am *not* talking about those below. - Question: How useful do people feel the Test Cases to be? I originally expected 99% of these tests to pass, but it turns out that most of them require: - The operands to be parsed and stored at the precision they appear in the Test Case file - The operation to be performed at precision of the operands - The high precision result to be rounded to the precision required by the Test Cases. - The test inputs to be parsed with correct rounding in underflow situations (not required by IEEE afaik) The above requirements are based on my experience with the tests - it is possible I'm making a blunder somewhere. Since the Test Cases are really testing the 3rd party library, an argument could be made they are not essential, or even desirable. I'm inclined to think they would be very, very nice to have, as they would give users a lot of confidence - I suspect user uptake would be poor without this confidence. So... what do people think? Regards, Josh.

Boost/Asio short read error
by Marcin Głogowski 15 May '12

15 May '12

Hi, I have problem with Boost/asio - sometimes server returns "short read" error. I'm using client/server from the examples. Please write me - is it a bug or just wrong implemented example because the error occurs not every time. How to protect my application against the error?

communicate with GSM MODEM
by Evaggelos Tsampazis 15 May '12

15 May '12

Hi Everyone! I would like to ask if someone knows how to use in detail the serial_port() mechanism. I want to create an API application where I will send SMS messages from the pc instead of the mobile phone/gsm modem. Of course, the mobile phone will be connected to the PC from a com or tty serial port. Despite that, I would also like to receieve the inbox from the mobile device. By other words, I need a way to send AT commands to my gsm device and then after receieve the answer. How can that be made easy? Thanks Evaggelos

Using BoostTest to run unit tests multiple times without quitting test runner
by Pankaj 15 May '12

15 May '12

I want to use Boost Test to run unit tests multiple times without quitting the test runner. Here is the pseudo-code to demonstrate what I want to do: void main() { for(int i = 0; i < 10; ++i) { char *arguments[] ={ "MyApplication.exe", "--detect_memory_leak=0" }; boost::unit_test::unit_test_main( &init_function, 2, arguments); } } The first time unit_test_main is called, all the boost tests run fine but in the second iteration, boost test throws an exception. I looked at the internal code and found that framework is initialized everytime unit_test_main is called and if framework is already initialized, boost test doesn't like initializing framework again. Please let me know if there is any way to run units test multiple times without quitting test runner. -- View this message in context: http://boost.2283326.n4.nabble.com/Using-BoostTest-to-run-unit-tests-multip… Sent from the Boost - Users mailing list archive at Nabble.com.

boost::bind and Motif
by Sven Bauhan 14 May '12

14 May '12

Hi, I just tried to use boost::bind to create a function pointer from an object method to define it as a Motif callback function: class AnimationController { public: void timerCB( XtPointer, XtIntervalId* ); void startTimer() { this->mTimeout = XtAppAddTimeOut( this->mAppContext, ANIMATION_TIMESTEP, boost::bind( &AnimationController::timerCB, this ), NULL ); } ... }; For the definition of the Motif function: XtIntervalId XtAppAddTimeOut( XtAppContext /* app_context */, unsigned long /* interval */, XtTimerCallbackProc /* proc */, XtPointer /* closure */ ); with typedef void (*XtTimerCallbackProc)( XtPointer /* closure */, XtIntervalId* /* id */ ); But I get the following error: ../AnimationController.cpp: In member function 'void geo::AnimationController::startTimer()': ../AnimationController.cpp:193: error: cannot convert 'boost::_bi::bind_t<void (&)(void*, XtIntervalId*), boost::_mfi::dm<void ()(void*, XtIntervalId*), geo::AnimationController>, boost::_bi::list1<boost::_bi::value<geo::AnimationController*> > >' to 'void (*)(void*, XtIntervalId*)' for argument '3' to 'XtIntervalId XtAppAddTimeOut(_XtAppStruct*, long unsigned int, void (*)(void*, XtIntervalId*), void*)' Can someone explain, what I did wrong? Thanks, Sven

Hi, I grabbed an mpl cross product implementation (product_view) of this mailing list.

Boost.Filesystem (?): How to get the platform-specific path separator (not directory separator) ?
by Johannes Stallkamp 14 May '12

14 May '12

Hi all, Boost.Filesystem eases use of path names across platforms w.r.t to the directory separator (slash vs. backslash, as I am only concerned with Linux <-> Windows). Now, I need to handle _lists_ of path names (in an environment variable). Is there a similar transparent way a) to automatically handle or b) access os-specific _path_ separators (colon vs. semicolon) in Boost.Filesystem or Boost in general? In other words, I am looking for the Boost (well, C++) equivalent of Pyhton's os.pathsep, Java's path.separator or PHP's PATH_SEPARATOR. And I am looking for a library function/constant rather than a self-implemented platform-dependent preprocessor directive. The only C++-solution I am currently aware of is "apr_filepath_list_merge"/"apr_filepath_list_split" in Apache Portable Runtime (as mentioned in this answer to my question on stackoverflow: (http://stackoverflow.com/a/10514401/1228449) Is there a similar way in Boost? Kind regards Johannes

Building boost with a locally built g++
by Mark Summerfield 14 May '12

14 May '12

Hi, I have two locally built g++'s and want to build boosts to go with them. Unfortunately I've never used jam and despite reading the docs haven't succeeded. I created a user-config.jam file with the single line: using gcc : 4.7 : /home/mark/opt/gcc47/bin/g++ : <compileflags>-std=c++11 -pedantic <linkflags>-lstdc++ -lpthread -L/home/mark/opt/gcc47/lib -L/home/mark/opt/gcc47/lib64 <address-model>64; but this seems to be ignored. All I want to do is build boost for my local g++ 4.6 in ~/opt/gcc46 and my local g++ 4.7 in ~/opt/gcc47. Can anyone give me or point me to some simple instructions for doing this? I did not find http://www.boost.org/doc/libs/1_49_0/more/getting_started/unix-variants.html at all helpful for my situation. In particular, section 5.2 didn't help and b2 just keeps using the system's /usr/bin/g++. (I want boost primarily for its regex library.) Thanks! PS I'm not a subscriber so would appreciate being cc'd in any reply. -- Mark Summerfield, Qtrac Ltd, www.qtrac.eu C++, Python, Qt, PyQt - training and consultancy "Programming in Go" - ISBN 0321774639 http://www.qtrac.eu/gobook.html

[build] How do I get my trial project to use b2 correctly?
by Daryle Walker 13 May '12

13 May '12

I'm trying out GitHub for the first time. I have a new project thatis supposed to reference my Boost-SVN tree for both the Boostheaders and its build system. I copied the project structure,including Jamfiles, from John Maddock's Multiprecision trial library.I don't think I did it right because calling "b2" doesn't do anything.At first, I got directory errors because it couldn't find my Boost tree.(The "../Trunk" alias doesn't work. Is it because I'm an extradirectory away?) Then I defined "BOOST" in my shell, so "b2" canfind the tree. I just get "1 target found" notices without anythinghappening. I know nothing's being compiled because I called it fortool-sets that aren't C++11-enabled and the build just ends withouterror on my C++11 code. My directories are like: + MyProjects++ boost-trunk++ Trunk (aliased to "boost-trunk")++ Unionize (a Git clone of my project on GitHub) Does anyone want to take a look and see how I have to fix my buildfiles? The project is at "https://github.com/CTMacUser/Unionize". Daryle W.

Interprocess file mapping - fixed addresses
by Steve 13 May '12

13 May '12

I hope someone on this list is sufficiently familiar with file_mapping, mapped_region and "Fixed Address Maping" to be able to offer advice. I have a very large file, and I want to map pairs of system-page-sized blocks from it into memory. The catch: I want to map non-consecutive blocks from the file into consecutive memory addresses. For example, with block 42 mapped to BASE_ADDRESS, I might want block 7 mapped to BASE_ADDRESS+PAGE_SIZE. Under Linux, using mmap() directly, I can use one of two approaches: 1. I can map two pages from the first file-block-start-location, then map one block from the second, using MAP_FIXED, at the address returned by the first mapping plus one page. 2. I could map two pages of /dev/zero - then map the first and second pages explicitly using MAP_FIXED into that address space - this copes with the case where the first block in memory is the last block of the file, but has an overhead. Both approaches seem to work, though I've not done extensive testing. I'd prefer to avoid using mmap directly - both to gain the advantages of a well-tested library using high-level C++ idioms - and to compile cross-platform... definitely targeting Linux and Windows - but maybe other platforms too. When I attempt to use the above strategy, I get a boost::interprocess_exception::library_error - though I'm not sure why. The following code fails on both Linux and Windows: -- size_t page_size=mapped_region::get_page_size(); file_mapping m("file.dat", read_write); mapped_region ra(m,read_write,0,2*page_size); uint8_t *base=reinterpret_cast<uint8_t*>(ra.get_address()); mapped_region rb(m,read_write,2*page_size,page_size,base+page_size); //FAILS -- whereas, the following appeared to work under Windows 7 (but not Linux) - perhaps by fluke of the way address space was allocated: -- size_t page_size=mapped_region::get_page_size(); file_mapping m("file.dat", read_write); mapped_region ra(m,read_write,0,page_size); // N.B. Map 1 page only uint8_t *base=reinterpret_cast<uint8_t*>(ra.get_address()); mapped_region rb(m,read_write,2*page_size,page_size,base+page_size); -- The documentation seems focused on MAP_FIXED being used to map specific data in a file into the same memory address on every invocation - with the obvious reference to validity of pointers referencing the mapped address space. Pointers are not a problem for me - my file contains no pointers - just a long stream of application-specific values. I only need to explicitly control two pages to be mapped into contiguous memory - I can be flexible about the mapped base address for the pair of pages - and it doesn't matter if different addresses are chosen on successive invocations.. as long as, in memory, the byte following the last byte of the first page is the first byte of the second page for an arbitrary pair of pages... irrespective of the locations of those pages in the file. Is this a use case that boost::interprocess intends to support? What is the most appropriate, robust, platform independent, way to reserve address space in order map into fixed addresses to ensure contiguous mappings? Do I need to mmap /dev/zero for POSIX systems - and use VirtualAlloc with MEM_RESERVE on Windows myself in order to use fixed-address memory mapping of files? Does boost offer anything to make this platform independent - or am I 'on my own'?
