Boost 1.58 linking error with Mongo 3.2
by Ameerkhan Mohamed 17 Dec '15

17 Dec '15

Hi, I am planning to use 3.2 mongo version. Hence i built client library of mongo 3.2 with pre-built boost library of 1.58. Both libraries are built under 64 bit configuration. Lib created successfully. When i integrate this libmongoclient-s.lib with my project i faced some linking error. Some of the sample error is :: Error LNK2001 unresolved external symbol "class boost::filesystem::file_status __cdecl boost::filesystem::detail::status(class boost::filesystem::path const &,class boost::system::error_code *)" (?status@detail@filesystem@boost @@YA?AVfile_status@23@AEBVpath@23@PEAVerror_code@system@3@@Z) StoreGrid_Head Error LNK2001 unresolved external symbol "class boost::system::error_code __cdecl boost::filesystem::detail::dir_itr_close(void * &)" (?dir_itr_close@detail @filesystem@boost@@YA?AVerror_code@system@3@AEAPEAX@Z) StoreGrid_Head Guide me on this issue please.

Re: [boost] [Boost-announce] Boost 1.60.0 rc1 is now available

Hi, (Resending to avoid bouncing on the lists.) I can build the libraries on FreeBSD 10.2 with clang 3.7 and gcc 5.2 in various modes. However, with both clang 3.7 and gcc 5.2 the following program fails to compile: #define BOOST_MOVE_USE_STANDARD_LIBRARY_MOVE #include <boost/thread.hpp> int main() { } This works fine with the same compilers and boost 1.59. The difference seems to be caused a change to boost/thread/detail/thread_group.hpp to use boost::csbl::unique_ptr<> instead of std::auto_ptr<>. Diff showing the change between 1.59 and 1.60 in thread_group.hpp and the compiler error messages below.

QVM formal review extension request
by Adam Wulkiewicz 16 Dec '15

16 Dec '15

Dear Boost Community! The number of reviews we received so far is too small to decide wether or not QVM should be a part of Boost. Therefore I request to extend the review period by a week to 23rd Dec. I'm aware that the time of year may be busy and that we're in the middle of Boost release. I hope that the extension would allow you to find time to write a short piece of review. -----The original announcement----- The formal review of Emil Dotchevski's QVM library is ongoing. Boost QVM defines a set of generic functions and operator overloads for working with quaternions, vectors and matrices of static size with the emphasis on 2, 3 and 4-dimensional operations needed in graphics, video games and simulation applications. While it provides its own quaternion, matrix and vector types, it is designed to work primarily with user-defined types through user specializations of the q_traits, v_traits and m_traits templates. QVM's source code is available on Github: https://github.com/zajo/boost-qvm Full documentation is also viewable on Github: http://zajo.github.io/boost-qvm/ We encourage your participation in this review. At a minimum, kindly state: - Whether you believe the library should be accepted into Boost * Conditions for acceptance - Your name - Your knowledge of the problem domain. You are strongly encouraged to also provide additional information: - What is your evaluation of the library's: * Design * Implementation * Documentation * Tests * Usefulness - Did you attempt to use the library? If so: * Which compiler(s) * What was the experience? Any problems? - How much effort did you put into your evaluation of the review? More information about the review process can be found here: http://www.boost.org/community/reviews.html We await your feedback! Best regards, Adam Wulkiewicz

Boost 1.60.0 beta 1 Release Candidate 4 available for testing
by Marshall Clow 15 Dec '15

15 Dec '15

After far too long, release candidate files for 1.60.0 beta 4 are available at http://boost.cowic.de/rc/ As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy. This helps ensure the candidates build OK before we push them out to SourceForge. Changes since rc3: * Boost.Test has been updated and now builds on Visual Studio Changes since rc1: * Boost.Sprit has been updated and Boost.Log now builds. * Boost.Math has been updated and now builds. Known issues (which will not be fixed for the beta): * Errors when building Boost.TypeErasure for older versions of Visual Studio. * Boost.Test fails when building on Darwin with gcc 4.9.2 The files (and associated md5s) are: MD5 (boost_1_60_0_b1_rc4.7z) = 63530c9594b24f56e5df79d910c9daeb MD5 (boost_1_60_0_b1_rc4.tar.bz2) = 29af12a1028536219a21517e953df4eb MD5 (boost_1_60_0_b1_rc4.tar.gz) = 74df7f5eb5e32f3a92b6141af3c6f541 MD5 (boost_1_60_0_b1_rc4.zip) = 90c25c34b64eb6cc88845ec5372938d7 Thanks! -- The release managers

Fwd: Re: [Boost-users] [boost-users][QVM] Boost.QVM formal review is ongoing
by Adam Wulkiewicz 15 Dec '15

15 Dec '15

It seems that you've send a response to the boost-users list and I'm guessing Emil is not a subscriber because he haven't responded. So I'm forwarding it to the developers mailing list. -----Original Message----- I'm not qualified to give a full review of this library beyond observing: 1 It looks very useful. 2 Boost prefers clarity to curtness. The naming is much too terse making the resulting code rather 'write-only'. I'd at least go for col_mat for col_m and transpose for transp etc. (I know any changes will be a big PITA but shows that asking sooner than later is a good idea for would-be Boost library authors ;-) 3 Documentation is OK, but I'd like many more examples of every function, and some much bigger fuller real-life examples showing use too. 4 Does this mesh at all with the quaternions in Boost.Math library? FWIW Paul PS If you build the Boost inspect tool \modular-boost\tools\inspect by running its jamfile, (and making sure that it is in your PATH) then from your /doc folder you can simply call > inspect > inspect.html and view any transgressions of the Boost rules in inspect.html - and, most important, any dud links. You may get a few false positives, but you can spot these easily. --- Paul A.

QVM formal review update
by Adam Wulkiewicz 15 Dec '15

15 Dec '15

Dear Boost Community! We're near the end of the QVM formal review period, it ends on 16th Dec. So far 11 people participated in discussions (not taking Emil nor me into account) and 2 reviews were sent. Do anyone of you need more time to ask questions, discuss, think, familiarize with QVM before sending a review? Are there people who would like to participate but haven't found enough free time so far? Basically I'm asking if anyone thinks that a review period should be extended? We appreciate your time and effort and of course kindly ask for sending reviews whenever you're ready. <TL;DR> -----The original announcement----- The formal review of Emil Dotchevski's QVM library is ongoing, it started on 7th Dec and it ends on 16th Dec.

safe integer library -- the scope
by Andrzej Krzemienski 14 Dec '15

14 Dec '15

Hi Robert, It is great to see this library getting into Boost. It fills an important gap, but it is only after a long while that I realized that, because the introductory part of the documentation does not stress it enough, and in fact it misled me a bit. My understanding is that safe<int> represents a high level abstraction of an integral number from mathematics: unlike raw type int, which represents a set of allowed operations on the underlying processor. You could say that raw type 'int' is only needed to efficiently implement higher level abstractions, like BigInt or safe<int> -- the two only differ in trade-offs between efficiency and the range of values they can represent. I was missing this in the introduction. Instead I got a somewhat negative impression that the goal of the library is to turn any UB into throwing exceptions (and thereby prevent any UB-based static analysis from detecting programmer errors). I would like to see the library in Boost, although I must admit the other parts do not sound that compelling as safe<int>. Regards, &rzej
