hi, I'm newbie. the only one thing that I wanted to ask is building boost 64bit on aix6.1. I try it a number of times. and I failed building 64bit boost objects. It built only 32bit objects. would you tell me how to build boost 64bit on aix6.1 thanks read this msg. 주식회사 테미 임영운(Yeong-woon Im) 305-764 대전광역시 유성구 대학로99 충남대학교 산학연교육연구관 807호 #807, TBI Center, Chungnam University 99 Daehak-ro, Yuseong-gu, Deajeon, 305-764 Korea Home URL : http://www.temee.co.kr Tel : 042-824-7014 Fax : 042-824-7015 Mobile : 010-6266-9960

[language] determine sence of language proposal concerning the 'default'-keyword
by Jakob Riedle 09 Apr '15

09 Apr '15

Hello boost community, since this seems to me kind of a proving ground for new C++ library/language features I'd ask this question here. Would you recon' writing a language proposal about: using the 'default'-keyword as some standard way of calling the default ctor of variables. I could imagine the following use-case: void foo( some::very_long_name<some_very_long_template_param> arg = default ){ return; } This would make things shorter, in the way 'auto' does it for types. You could also do it for passing parameters: foo( default ); This could interact very well with boost::optional, make it more intuitive and easier to use: optional<int> bar( optional<some_long_type_name> arg = default ){ return default; } bar( default ); This way, you don't have to write 'optional<some_long_type_name>()', both at the parameter and at the function call. What do you think of such a language proposal? Regards, Jakob Riedle

[MinGW] [Windows] [build boost 1.57] Help required to build boost
by Abhinav Tripathi 08 Apr '15

I had submitted a GSoC application regarding developing a document library for boost and i wanted to do something regardless of the results of selection. . SO, i downloaded boost 1.57 source and tried to build it using MinGW compiler that i downloaded with CodeBlocks IDE which i use. When i ran : bootstrap.bat gcc I got error "Failed to build Boost.Build Engine". .

[flat_map] Any interest in a flat_map variant that is much faster on insertion/erase at the price of a slower lookup?
by Giacomo Drago 08 Apr '15

08 Apr '15

Hi My library is not ready for a formal review process, and I'd like to ask whether there is some potential interest first, thus saving everybody a lot of time. I have been working on a flat_map (http://www.boost.org/doc/libs/1_57_0/doc/html/boost/container/flat_map.html) variant that keeps some of the distinctive features of the original one (contiguous storage/cache friendliness, zero memory overhead/shrink_to_fit support, vector-based representation, etc...) but makes insertion and erasure of the elements much faster, at the price of a slower lookup and in-order traversal. Explaining how it works requires time and it's not really necessary if there is no interest in the first place (e.g. "thanks, but we have no use for this"). Let's get straight to the benchmarks and to some conclusions. #elems: 50000 std::map: Random insertion: 18.605 ms Random find: 24.382 ms Iteration: 5.658 ms Random erase: 37.166 ms experimental::flat_map: Random insertion: 400.141 ms Random find: 12.352 ms Iteration: 7.099 ms Random erase: 467.051 ms boost::container::flat_map: Random insertion: 611.678 ms Random find: 6.293 ms Iteration: 0.038 ms Random erase: 615.311 ms #elems: 200000 std::map: Random insertion: 146.394 ms Random find: 163.506 ms Iteration: 21.973 ms Random erase: 225.314 ms experimental::flat_map: Random insertion: 5068.93 ms Random find: 65.618 ms Iteration: 34.244 ms Random erase: 6851.09 ms boost::container::flat_map: Random insertion: 10696.9 ms Random find: 43.896 ms Iteration: 0.254 ms Random erase: 10604 ms Of course one doesn't expect the random insertion to have a performance that is comparable to the one of a tree-based map, like std::map. However, my experimental::flat_map provides a better trade-off than boost's flat_map for me, as random insertion is massively faster and in the big picture of the application I am developing this is making a hell of a difference. Am I making any sense? Shall I polish the implementation, publish it, and submit a proposal? I'd really appreciate your feedback. Kind Regards Giacomo

Re: [boost] [SORT] Parallel Algorithms
by Francisco José Tapia 07 Apr '15

07 Apr '15

Hi , In the file of this link, in my dropbox space, you have the code, the test programs and the benchmarks with GCC. https://dl.dropboxusercontent.com/u/8437476/works/sort/Sort_V0.1.7z *FILE DESCRIPTION* In the root folder of the file you have a INSTRUCTIONS.txt file detailing the content of all the folders of the file, information for to compile the programs, where is each file, and which options and libraries you must link. *Test* Contains the test programs of each class and algorithms. *Src* Contains the source code of all. In the folder *src/boost/sort* there is a file *algorithm.hpp*, which is the only include file needed for invoke the algorithms. The parallel algorithms have a parameter of the NThread type which indicate the number of threads to use. By default use the same number than the HW threads of the machine. it's a very simple structure defined in boost/sort/util/atomic.hpp. *Benchmarks* In this folder are the benchmark code with GCC compiler under Linux x64. In the future I will add benchmarks with other compiler and Operating Systems. The folders *cpp-TimSort-master*, and *parallel_stable_sort* have the C++ code of the TimSort algorithm, found in https://travis-ci.org/gfx/cpp-TimSort, and the code of the sample sort with TBB. The code had been modified, due to the four versions use the same name space and many common names, and was not possible invoke the four versions in the same program. The modification put each version in a different name space. In the folder *GCC*, you can find 3 folders - *algorithm* : Have the code of the benchmark programs - *bin *: have the compiled and static linked version of the benchmark programs. In this folder you have a shell run.sh which run sequentially the programs and collect the results obtained in .txt files with the same name than the program - *Results *: in this folder you can find the result generated by the benchmark programs on different machines. Each machine have a folder where you can find the text files with the same name than the programs with the results, and a description.txt file with the description of the HW where run the benchmarks. The format used in this folder is the suggested for to present the results of all the machines used in the test. Here you have the result of my two computers, and can have a first idea about the results expected in other machines. The benchmarks, like in the old version, have a version with 64 bits numbers, and a version with objects of several sizes. About the memory used for of the algorithms. If you consider M the memory used by the data, the total memory used by the algorithms are : - GCC sort → M - boost sort → M - GCC parallel_sort → M - boost parallel_sort → M - TBB parallel_sort → M - GCC stable_sort → 2 M - boost stable_sort → 1.5 M - TimSort -> 2M - GCC parallel_stable_sort → 2.5 M - TBB parallel_sort → 2 M - boost sample_sort → 2 M - boost parallel_stable_sort → 1.5 M The algorithms use the indirect version when the size of the objects is greater than 128 bytes. I am speaking with several friends, for to run the benchmarks in more powerful machines. I think, the first is to check the speed. If the speed is good, we have something useful , if not, we must decide what must do with this. If something is useful , or we must leave all. If we decide continue, the next steps to do are : Reorganize the benchmark, and include benchmarks with string objects. Your idea about the use of files, I thing is the correct way to follow Finish all the documentation of the code for to generate a Doxygen documentation Generate the web pages of documentation for the Boost project Modify the test programs for to do according the bjam files If you found any problem , error or doubt, please , contact me for to resolve Francisco

[sync] Needs a 'master' branch

I created a Github issue that the sync library needs a 'master' branch, even if its just the current 'develop' branch. Please let's get this done. It is more than just irritating that: git submodule foreach --recursive git checkoout master stops and fails because a Boost library does not have a 'master' branch.

[VS++ 2015 CTP 6] [build] Workaround for Visual Studio 2015 CTP 6 Preview breaking Boost.Build
by Beman Dawes 02 Apr '15

02 Apr '15

If you have previously been running Boost.Build on toolset=msvc-14.0 (Visual Studio 2015 Preview), installing CTP 6 causes some bjam/b2 builds to fail because of missing include files. What's happening is that Boost.Build caches several files in C:\Users\<name>\AppData\Local\Temp. For my installation these files are: b2_msvc_14.0_vcvarsall_x86.cmd b2_msvc_14.0_vcvarsall_x86_amd64.cmd b2_msvc_14.0_vcvarsall_x86_arm.cmd but the introduction of the new universal runtime stuff in CTP 6 added some additional paths to vcvarsall, so the cached files are no longer correct. The workaround is to simply delete the b2_msvc_14.0_vcvarsall* temporary files. The next time bjam/b2 is run correct versions of the files will be regenerated. --Beman

[rational] Can the community maintenance team and/or rational users please review some pull requests?
by John Maddock 02 Apr '15

02 Apr '15

I have a bunch of PR's against Rational, which of course is basically unmaintained. I'd be grateful if a second pair of eyes (at least) could take a look before I start agitating for someone to merge them ;) Each of the four, builds on the previous one(s). Three are basically trivial: https://github.com/boostorg/rational/pull/1/files https://github.com/boostorg/rational/pull/2/files https://github.com/boostorg/rational/pull/3/files The final one is much more complex, and disables "accidental" conversion from float to rational (which otherwise proceeds via truncation to integer first). As you can see from the commit history, I've had quite a few attempts at getting the final one correct. I believe it is now, doesn't break anything in Boost except, as noted in the discussion, Boost.Geometry, which relies on an unsafe float to rational conversion - Geometry's authors are aware of the issue here: https://github.com/boostorg/geometry/commit/c992eb61e8ef9e90fdae403ac6ff1ee…. So.... I'm interested in both eyeball-look-throughs from seasoned Boosters, but also feedback from Rational's users, and verification that it doesn't break end user code - other than unsafe conversions of course. If you just want the updated header to test, you can grab it from here: https://raw.githubusercontent.com/jzmaddock/rational/no-float-convert/inclu… Many thanks! John.

MPL and MPL core
by Edward Diener 02 Apr '15

02 Apr '15

Were the changes to MPL splitting it between a core and the rest of MPL supposed to be part of the upcoming release ? Because looking at MPL the 'master' branch is at the previous 1.57 release and there have been quite a number of changes to the 'develop' branch since then, much of it relating to the mpl/core split. The 'develop' regression tests for MPL look pretty green. I would like to get bruno Dutra's fix for MPL arity into the coming release as it has been thoroughly tested on 'develop', but I do not know whether or not all the other MPL 'develop' changes should go in 'master' although I suspect not.

questions regarding GCC visibility
by Robert Ramey 02 Apr '15

02 Apr '15

I made a few changes to simplify code in the serialization library. This entailed eliminating support for borland compilers, workarounds for compilers which fail to support partial specialization of template function and some general clean up. In the course of this effort, I had occasion to simplify the code which supports Auto linking - and by extension visibility. Things seemed to go pretty well. Feeling frisky, I added the switch -fvisibility=hidden to the gcc compile of library. Now applications won't link for lack of certain symbols. Well, they link and run fin on my machine here at home- but fail in the test matrix. http://www.boost.org/development/tests/develop/developer/output/Debian-Sid-… Funny thing is: doesn't seem to be a problem on my machine doesn't seem to occur with all exported symbols - only select ones - often but not always desctructors I can switch Jamfile back so it doesn't specify -fvisibility=hidden, but it seems that I'm really close to being able to generate a smaller, cleaner DLL which I would prefer to do. Any constructive suggestions would be appreciated. On a related note, it seems to me that http://www.boost.org/development/separate_compilation.html should be updated to explain BOOST_SYMBOL_EXPORT and BOOST_SYMBOL_IMPORT which are convenient for simplifying the auto-linking and visibility functionality.

[log] [asio] Conflicting default configs
by Andrey Semashev 01 Apr '15

01 Apr '15

Hi, In Boost.Log I'm using Boost.ASIO to implement network-based syslog backend. Boost.ASIO is used in the compiled part of Boost.Log and, obviously, can be used in the user's code as well. By default Boost.ASIO is header-only, so we basically have a copy of Boost.ASIO in Boost.Log and another copy in the user's app. In Boost.Log I have the option to enable compiler-based TLS at the library build stage (BOOST_LOG_USE_COMPILER_TLS macro), which is by default not enabled. In Boost.ASIO there is a similar option (BOOST_ASIO_DISABLE_THREAD_KEYWORD_EXTENSION macro) but the feature is enabled by default. I want Boost.Log built libraries to actually respect the BOOST_LOG_USE_COMPILER_TLS option, so I define BOOST_ASIO_DISABLE_THREAD_KEYWORD_EXTENSION internally when BOOST_LOG_USE_COMPILER_TLS is not defined. The problem is that Boost.ASIO changes implementation in an incompatible way when BOOST_ASIO_DISABLE_THREAD_KEYWORD_EXTENSION is defined. It is further worsened by a recent change that makes all of Boost.ASIO symbols externally visible. Basically, this means hard to debug trouble on user's end, when different versions of Boost.ASIO (one from Boost.Log binaries and the other used by the user's code directly) are used at the same time. I'd like to ask community what is the preferred resolution of this situation (and possibly similar ones in the future). I can see several ways of tackling this: 1. Introduce an inline ABI namespace in Boost.ASIO, much like the one I have in Boost.Log. The namespace name would depend on BOOST_ASIO_DISABLE_THREAD_KEYWORD_EXTENSION and other macros that affect binary compatibility. This would be my preferred solution, although I'm not sure how fast and easy it can be implemented. 2. Remove symbol visibility enforcement from Boost.ASIO, or at least make it optional. That way I could encapsulate my private copy of Boost.ASIO in Boost.Log binaries. 3. Change the defaults, either in Boost.Log or in Boost.ASIO, so that they are aligned by default. When the user changes Boost.Log config he would be expected to know that Boost.ASIO config also needs to be changed accordingly. If he doesn't, Boost.Log is still built consistently with its own config. Note, however, that since Boost.Log is a built library and in most distributions it is built with default options, the choice for Boost.Log is more significant and because of that should probably be more conservative. 4. Same as 3 but also remove the enforcement of Boost.ASIO config by Boost.Log. Whenever the user wants to change the default, he would have to define macros for the both libraries, otherwise Boost.Log can be built inconsistently. 5. Do not change the defaults but remove the config enforcement. BOOST_LOG_USE_COMPILER_TLS becomes Boost.Log-local and as such does not guarantee that the resulting binaries do not in fact use compiler-based TLS. Users can get surprised. 6. Do not change anything, let the users suffer because of ODR issues. Maybe document this somewhere... Opinions?

Transferring a library on Github
by Edward Diener 31 Mar '15

31 Mar '15

In order to get VMD under boostorg in order to begin the process of integrating the library into Boost for the release after the current pending one I tried to transfer the library as explained on the page https://svn.boost.org/trac/boost/wiki/NewLibFromGit. But I do not have the necessary admin rights for boostorg. How do I proceed ? I want to get VMD under boostorg and then do whatever is necessary to add it to the superproject and have it part of for regression testing.
