[ sorting_view ] -do not sort arrays, sort iterators instead
by Boris Kats 27 Feb '16

27 Feb '16

The sorting procedure is one of the most usable routine in programming.And all sorting template functions have the same signature:template< class RandomIt, class Compare >void sort( RandomIt first, RandomIt last, Compare comp );with conditions: the type of dereferenced RandomIt must meet the requirements of MoveAssignable and MoveConstructible.It is clear that in the sorting process a lot of records are moving in the memory andwhen these records have a big size, these movements, together with calling constructors, can be very expensive.Solution.The proposed template function sorting_view is free of that problem - the sorting procedureis working (and moving) on tiny objects - iterators. As result of that procedure,the initial array of records is remaining intact; however provided std::vector<int> viewallows indirect access to the sorted array. On many occasions user does not need the sortedarray at all and he/she has a luxury to iterate through sorted and unsorted arrays simultaneously.In case of real needs of sorted array, it can be obtained via other template function apply_view with exactly 2*N movements of the records, where N is the size of initial array.For getting sorted view of arrays of user's defined records the appropriate Compare template function should be supplied.Happy sorting, Boris Kats.

Help: Errors compiling SESHAT project
by C. Ichongiri 26 Feb '16

26 Feb '16

Hey there, I've been at this for days now and can't seem to find anything to help with this: I got the project at https://github.com/falvaro/seshat and followed the instructions exactly as-is: - Got the *Boost* headers - Have got *g++ *compiler ( versions 5.2, 4.9, 4.7, 4.5, 4.3) and my default *clang++* *- Makefile *is present *P.S.* I'm on *OS X Mavericks*; Used *MacPorts* to install all above gcc versions *except *5.2, which was manually done following this tutorial: https://solarianprogrammer.com/2015/05/01/compiling-gcc-5-mac-os-x/#comment… However, when I attempt to compile it, I get the following errors (attached in the Textfile below). A screenshot image also attached shows the filesystem and path I am working with, from where the error file was created. Honestly, I'm at my wits end now, especially with my being new to C++. ANY helpful insight into this would be MOST APPRECIATED. Much thanks in advance, chiich.

Build Boost.Context with Visual Studio
by Thomas Ziegenhagen 26 Feb '16

26 Feb '16

Hi there, I'm building the required portions of Boost myself, along with all my other projects. It turned out that even the smallest compiler setting changes lead to strange crashes, some of which only occured on 5% of the client's systems, so I will not use externally built boost libraries anymore. So now I'm building the parts of boost which I require, which works fine so far. The trouble starts when I tried to use Boost.Context. It also contains ASM code, which I now need to build in Visual Studio 2015. VS2015 does not have builtin Asm support, for x64 it never had. So I'm invoking the Microsoft assembler as a custom build step. Command line is as follows: ml64 /Fo path/to/obj/file.obj /c path/to/source/jump_x86_64_ms_pe_masm.asm Documentation is as scarce as usual, but I figured from the filename that jump_x86_64_ms_pe_masm.asm is the correct file for Microsoft Visual Studio, x64. But assembling failed, and to add insult to injury, the error messages are lost somewhere in the output piping process. The complete output reads like this: ------ 1>------ Erstellen gestartet: Projekt: boost, Konfiguration: Debug x64 ------ 1> Microsoft (R) Macro Assembler (x64) Version 14.00.23506.0 1> Copyright (C) Microsoft Corporation. All rights reserved. 1> 1> Assembling: C:\Projekte\DeadPlanet\SourceExt\boost\context\asm\jump_x86_64_ms_pe_masm.asm 1> C:\Projekte\DeadPlanet\SourceExt\boost\context\asm\jump_x86_64_ms_pe_masm.asm(80)ied size 1>: error A2008 : syntax error : FRAME 1> C:\Projekte\DeadPlanet\SourceExt\boost\context\asm\jump_x86_64_ms_pe_masm.asm(81)ied size 1>CUSTOMBUILD : warning A4020: directive ignored outside a procedure 1> C:\Projekte\DeadPlanet\SourceExt\boost\context\asm\jump_x86_64_ms_pe_masm.asm(215 1>CUSTOMBUILD : fatal error A1010: unmatched block nesting : jump_fcontext ------ Please note that the actual error messages are overwritten by the filename - I can only guess at what buffer magic happens there, but I'm pretty sure it's not intended. But that's just a funny anecdote. My actual question is: how do I build Boost.Context in Visual Studio? Is there maybe some way to see the effective command line when building using Boost.Jam? Is this even the right ASM file for x86_64, Visual Studio? Thanks in advance! Bye, Thomas

Spherical Bessel function (nu, x as real) implementation
by campagne 26 Feb '16

26 Feb '16

Dear developpers, 1) Does you use this reference to compute Spherical Bessel Functions for real argument? Accurate recursive generation of spherical Bessel and Neumann functions for a large range of indices E. Gillman <http://scitation.aip.org/content/contributor/AU0510272>^1 and H. R. Fiebig <http://scitation.aip.org/search?value1=H.+R.+Fiebig&option1=author&option91…>Comput. Phys. 2, 62(1988); http://dx.doi.org/10.1063/1.168296 2) is there a way to speed up the computation of j_nu(x) if one wants 10 digits accuracy for instance? Best regards J.E

[ASIO] Resolver question
by Davies, John 26 Feb '16

26 Feb '16

I have some pretty simple UPD code. (It has to be simple, I'm new at ASIO) boost::asio::ip::udp::resolver::query query(boost::asio::ip::udp::v4(), addr, port); m_receiverEndpoint = *m_resolver.resolve(query); If my address is 192.168.1.112 everything works If my address is 192.168.001.112 it doesn't work and throws an exception about not finding the host. It's not a big deal, but it sure took me a long time to track down. Is there some sort of Boost magic I can do to convert the bad address into a good address?

[graph] abort algorithm execution from a visitor
by Frank Tetzel 23 Feb '16

23 Feb '16

Hi all, i played around with the bfs example calculating distances to all vertices. Now i just want to calculate the distance between two vertices, so i want to stop when the target vertex is visited. If i understood the visitor concept correctly it's not really possible to change the behaviour of the algorithm from a visitor. Does anybody know of any workaround to do early exit? Do i have to implement a new algorithm for this? In a different thread on this list Paolo Bolzoni wrote that he aborts in a custom visitor by throwing an exception. Is this the only way? I'm using bfs here and not dijkstra because i have uniform edge weights. Btw, if someone could fix the documentation that would be really nice: http://www.boost.org/doc/libs/1_60_0/libs/graph/doc/bfs_visitor.html The code snippet there did not work for me. I had to wrap make_bfs_visitor() in visitor() like it is done in examples/bfs.cpp too. Regards, Frank

Boost 1.60 Raspberry Pi lockfree::queue compilation error
by Alexander Simpson 23 Feb '16

23 Feb '16

Hello, I’m trying to compile a project that makes use of boost::lockfree::queue on a Raspberry Pi 2 running Jessie. I built version 1.60 of Boost myself (apt-get was out of date) with sudo ./bjam install. I’m not cross-compiling. When I attempt to compile a project that uses the boost library I get the error listed below (where boostreader.cpp is the file written by me). I found a patch suggested two years ago here (https://svn.boost.org/trac/boost/ticket/9041 <https://svn.boost.org/trac/boost/ticket/9041>) but the changes in that patch seem to have already applied in 1.60, so I’m at a loss as to what to do. Assistance would be greatly appreciated.

boost 1.54: problem with building documentation.

Hallo people. I need to have documentation in man pages format on my ubuntu 14.04. Unfortunatelly, I fail with this task. The following are the steps I've performed. In step 11 I do "../b2" instead "../b2 man" just to highlight that the problem is not related to building the man pages. Of course "../b2 man" fails as well Could You please help me with it? 1. install following packages for man pages build. lubuntu.14.04$ sudo apt-get install xsltproc lubuntu.14.04$ sudo apt-get install doxygen 2. lubuntu.14.04$ dpkg --list | grep libboost-all ii libboost-all-dev 1.54.0.1ubuntu1 i386 Boost C++ Libraries development files (ALL) (default version) 3. download boost_1_54_0.tar.bz2, unpack to ~/ 4. cd ~/boost_1_54_0 5. ./bootstrap prepares build configuration and puts it to project-config.jam. 6. ./b2 builds whole the boost libraries, but does not install them into the system. 7. lubuntu.14.04$ export BOOST_ROOT=/home/userp/boost_1_54_0 8. lubuntu.14.04$ cd ~/boost.doc/ 9. lubuntu.14.04$ ~/boost_1_54_0/tools/boostbook/setup_boostbook.sh Downloading DocBook XSLT Stylesheets version 1.75.2...
