The boost branch. The link https://github.com/pfultz2/Fit/tree/boost points directly to the repository that will be reviewed. Vicente

Hi, Is there still somebody in charge of the bimap package? There are 2 trivial pull requests lying around since last summer. It would be nice to see them integrated. Thanks, Sebastien.

[config] config.requires and simple_run
by Steven Watanabe 27 Feb '16

27 Feb '16

AMDG I've just been trying to get MinGW working without requiring the compiler's bin directory to be in the PATH. It mostly works now, but unfortunately I ran into problems with simple_run_action. The problem essentially is that this rule ignores RUN_PATH, which may be set by some toolsets (a quick grep shows borland, cw, gcc, and intel) to indicate additional paths that must be added to PATH when running the executable. In addition, I'm wondering how this is supposed to work with a cross-compiler. We really shouldn't be requiring cross-compilers to have access to the target system for ordinary builds. In Christ, Steven Watanabe

[Experimental Boost.DI] [v1.0.0 released] [Looking for a Review Manager] Your C+14 Dependency Injection library with no overhead and compile time creation guarantee!
by Krzysztof Jusiak 27 Feb '16

27 Feb '16

Dear Boosters, I have just released version 1.0.0 of experimental Boost.DI library. Your C++14 header only Dependency Injection library with no dependencies. Library entered Boost Formal Review Queue some time ago and right now, IMHO, is ready to be reviewed. http://www.boost.org/community/review_schedule.html Therefore, I'm looking for a Review Manager, so if you think that Boost.DI is good enough to be reviewed and you would like to help with it, please let me know. Thank you! In the mean time check out the library yourself online! http://boost-experimental.github.io/di/examples/index.html Or read the interactive documentation... http://boost-experimental.github.io/di Or check out the source code... https://github.com/boost-experimental/di Why Boost.DI? * Boost.DI has none or minimal run-time overhead * Boost.DI compiles fast / Faster than Java-Dagger2! * Boost.DI gives short diagnostic messages * Boost.DI is non-intrusive * Boost.DI reduces boilerplate code * Boost.DI reduces testing effort * Boost.DI gives better control of what and how is created * Boost.DI gives better understanding about objects hierarchy Read more why here -> http://boost-experimental.github.io/di/index.html Any feedback is more than welcome! Cheers, Kris

GSOC-2016
by Abhimanyu Shekhawat 27 Feb '16

27 Feb '16

Hi there ! I am Abhimanyu Shekhawat, a sophomore perusing B.E(Hons)Computer Science, Birla Institute of Technology & Science, Pilani - Goa,India. I would like to take part in GSOC Programme 2016 with Boost Community. Actually I am very excited about contributing to open source projects and I already have experiences with some of the college based projects till now.I feel that being able to work in open source community will not only expose me to new learning avenues but will also give me a chance to contribute to the a much larger community. As far as my background is concerned,I have taken a course on Discreet Mathematics and currently perusing a rigorous Algorithm and Data structure course. Also I have got an intermediate level of skill set in C++,C,Java,Android and Mysql while a basic understanding of python. I hope that my skills and enthusiasm will prove an asset to the community.So I will be grateful if you can get me started Thank you :D

[hana] missing .gitattributes
by Steven Watanabe 27 Feb '16

27 Feb '16

AMDG I just noticed that all the files for hana had \n line endings in my working copy. To fix this I had to copy .gitattributes from the superproject. (Or am I just using git wrong) In Christ, Steven Watanabe

[log][thread][teeks][igaztanaga] Log & Thread tests failing on MSVC & MinGW
by Andrey Semashev 26 Feb '16

26 Feb '16

Hi, I can see lots of Boost.Log tests are failing on igaztanaga and teeks99-08 testers [1], while the error logs are non-descriptive (show a successful compilation). For some tests the links in the table refer to successful compilation of Boost.Thread, which I can see is failing on the same testers the same way [2]. What's interesting, teeks99-09 testers are green for both libraries. Is there a known problem with Boost.Thread on Windows? Or with these particular testers? If not, is it possible to see the actual failure logs? PS: Disregard the MSVC-7.1 and gcc 3.4 columns. These old compilers I don't expect to work.

toml parser for boost::property_tree
by Auer, Jens 26 Feb '16

26 Feb '16

Hi, is somebody working (or has been) on a property_tree parser for toml (https://github.com/toml-lang/toml)? if not I would give it a try. It looks like a project with reasonable for a single person, but complex enough to involve some interesting components, e.g. boost::spirit.

[interval] rounded_arith_opp doesn't work in Release configuration under msvc 14
by Peter Azmanov 25 Feb '16

25 Feb '16

Hello, Interval calculations with rounded_arith_opp in Release configuration under msvc 14 result in zero-size intervals. For example consider following: #include <iostream> #include <boost/numeric/interval.hpp> int main(int argc, char * argv[]) { unsigned int ctrl = _control87(0, 0); _control87(_EM_INEXACT | _RC_UP, _MCW_EM | _MCW_RC); using namespace boost::numeric::interval_lib; typedef typename unprotect< boost::numeric::interval<double> >::type interval_t; interval_t test = interval_t(1.) / interval_t(3.); std::cout << "test.lower() != test.upper(): " << std::boolalpha << (test.lower() != test.upper()) << std::endl; return 0; } This test unexpectedly prints: test.lower() != test.upper(): false Tested on x64 platform with /fp:strict and /fp:precise under MS Visual Studio Community 2015 Version 14.0.24720.00 Update 1, Boost 1.60. I've already reported this to https://svn.boost.org/trac/boost/ticket/12018 There you can find some details of what I think is going wrong and proposed workaround patch. I didn't create pull request because I'm not sure if my patch is a correct workaround. Maybe someone will propose more appropriate solution. Best regards, Peter Azmanov.
