1.58.1 bugfix release necessary?
by Oliver Kowalke 27 Apr '15

27 Apr '15

Unfortunately boost.context fails to compile for gcc-4.8.x and option -std=c++11. Because of a dependency to boost.context, boost.asio and boost.coroutine do not compile too. I've pushed a pull-request to boost.config - the patch adds C++14 test macro BOOST_NO_CXX14_INTEGER_SEQUENCE ( https://github.com/boostorg/config/pull/57) Oliver

[vmd] Getting regression tests
by Edward Diener 27 Apr '15

27 Apr '15

I created a pull request for boostorg/boost so that VMD is added to the regression tests. It has been sitting there for a long time now. Can someone at the Boost superproject level please address this pull request ? I want to have VMD added as a library in the next Boost release.

Boost 1.58.0 has been released
by Marshall Clow 26 Apr '15

26 Apr '15

Release 1.58.0 of the Boost C++ Libraries is now available. These open-source libraries work well with the C++ Standard Library, and are usable across a broad spectrum of applications. The Boost license encourages both commercial and non-commercial use. This release contains two new libraries and numerous enhancements and bug fixes for existing libraries. New Libraries * Endian: Types and conversion functions for correct byte ordering and more regardless of processor endianness. * Sort: Includes spreadsort, a general-case hybrid radix sort that is faster than O(n*log(n)) For details, including download links, see http://www.boost.org/users/news/version_1.58.0 You can also download directly from SourceForge: http://sourceforge.net/projects/boost/files/boost/1.58.0/ To install this release on your system, see http://www.boost.org/doc/libs/release/more/getting_started/index.html Thanks, --The Boost release team Vladimir Prus Rene Rivera Marshall Clow Eric Niebler Daniel James Beman Dawes

[interprocess] condition variables and spurious wakeups
by eg 26 Apr '15

26 Apr '15

Hi, I was hoping to get some clarification on whether the boost::interprocess library implementation of condition variables is susceptible to spurious wake ups. Most other library implementations (pthreads, boost::thread, std::thread) seem to be and are documented as such. I couldn't find any mention in the interprocess documentation nor find anything definitive in my google searching. Thanks in advance, Ed

[boost_document_library] [GSoC'15] How to Start? Any standards to follow?
by Abhinav Tripathi 25 Apr '15

25 Apr '15

Hello, I have finally set up my development environment on Ubuntu 14.10 x64... I am now able to compile any program consisting of Both OpenOffice and Boost code. I have made succesfully small examples with multiple files with both boost and OpenOffice sdk code and compiled them. . I am now ready to start writing code for the document library. What i could think of till now is : 1. Make the project on github and keep it synced 2. Separate classes in different headers with proper namespaces . What i am looking for : 1. Any suggestions on how to start! (More specifically) 2. Are there and standards that need to be followed for developing any library for boost (like using or not using some syntaxes &/or libraires) 3. Any suggestions as to what practices i should use, like which syntaxes/libraries to prefer. . Also, i see that all the boost libraries are independent (i.e., only dependence is within boost itself) [as far as i know]. While what i will be writing will depend on OpenOffice sdk. So, what are its chances to be accepted as an "actual boost library"? . Regards, Abhinav

tokenizer for overlapping delimiters?
by Jorge Cardoso Leitão 25 Apr '15

25 Apr '15

Dear boost devs, I'm writing here because I've been coding a tokenizer that I believe, given its generality, could be an addition to Boost. I'm asking for a judgement on whether the idea has room in boost or not. The interface I'm proposing is a function of two arguments, a string (call it text) and a set of strings (call it key-terms), that returns a vector<string> (call it result) which fulfils 4 constraints: 1. a string in the result can only be either a key-term or a string between two key-terms; 2. the concatenation of the result is always the original text; 3. a key-term containing other key-terms has priority over the latter; 4. a key-term overlapping other has priority based on its position in the text A tokenizer that divides a string by delimiters is a subset of this interface whose key-terms are the delimiters. This is considered in Boost.Tokenizer, where the key-terms are *non-overlapping. *The critical addition here is the ability to deal with *overlapping key-terms*. A common use case of overlapping key-terms is when you have key-terms that you want to consider as single tokens but they overlap with common delimiters. A practical example: tokenize a string (with words separated by spaces) and guarantee that both `"United States of America"` and `"United States of Brazil"` are interpreted as single tokens. The non-triviality appears because such feat requires storing which key-terms are using a previous sub-string, and how to reverse in case the match fails. (e.g. "United States of " is common to both terms above, but once the first letter appears, either one or both can be discarded as potential matches). Some examples in pseudo-code (see how they fulfil constraints 1-4) tokenize("the end", {}) --> {"the end"} tokenize("the end", {" "}) --> {"the", " ", "end"} tokenize("foo-bar", {"foo", "foo-bar"}) --> {"foo-bar"} tokenize("the end", {"the e", " ", "end"}) --> {"the e", "nd"} tokenize("foo-tars ds", {"foo", "foo-bar", "-tar"}) --> {"foo", "-tar", "s ds"} As a proof of concept, I've implemented such interface and respective test cases, which you can find in https://github.com/jorgecarleitao/tokenize. Any change is possible to accommodate to boost standards: this can be generalized to arbitrary sequences, to arbitrary types, and to use iterators, documented, better tested etc. But before anything else, I would like to ask for an opinion on whether this is sufficiently general and useful to be considered to boost. Thank you for your time, Best regards, Jorge

Description of pre-requisites for building Boost 1.58.0?
by Marko Asplund 25 Apr '15

25 Apr '15

Hi, While trying to build Boost on Ubuntu 14.04.2 LTS I noticed that the build failed because some library dependencies were missing on my system. I was unable to find documentation about library dependencies and other pre-requisites for building Boost. Are these documented somewhere? Some build related info can be found here, but I couldn't find info about required libraries: http://www.boost.org/doc/libs/1_58_0/more/getting_started/unix-variants.html I was able to build Boost after installing libpython-dev, libbz2-dev packages. This was with default Boost configuration, so other libraries may be required for custom configurations. marko
