[release] 1.75.0 open for merging
by Marshall Clow 14 Aug '20

14 Aug '20

The master branch is open for merging all stable changes from develop, including bug fixes and major upgrades to existing libraries. Breaking changes should be coordinated via the mailing list with the developers of the other libraries affected. New libraries may be added, but require permission of a release manager. In other words, merging does not require permission from a release manager, except for new libraries.

[test] runtime failures with "main() should return report_errors()"
by stefan 14 Aug '20

14 Aug '20

Hello, With the Boost.Python tests I'm observing a couple of mysterious failures, where the test application fails *after* the actual test succeeded, with a message main() should return report_errors() I gather this error is emitted by the Boost.Lightweight_test library whenever a test's main() function does not call `report_errors()` at the end. The problem in my case is that my failing tests are not (explicitly) using Boost.Lightweight_test. In fact, in all of the failing cases I'm not even writing a `main()` function, as the test driver is a Python script that's importing a (test) module. For example: https://www.boost.org/development/tests/master/developer/output/teeks99-05-… Does anyone understand or has an idea how this could happen, and how to fix this ? Thanks, Stefan -- ...ich hab' noch einen Koffer in Berlin...

current situation with clang-cl?
by Dennis Luehring 13 Aug '20

13 Aug '20

some of my project using boost building with clang-cl but there are still some libraries that don't is there any official interest in supporting clang-cl or is it up to a library maintainer to support it? many project of mine building better and better, boost 1.73 currently is neary full useable with clang-cl without any problems today i tried to compile a 600KLOC project and it failed with the same problem Libreoffice got they are using a patch to "fix" its used boost version https://github.com/LibreOffice/core/blob/62808ef28e05eee4945a6a15d981350d13… https://github.com/boostorg/thread/issues/286 "clang-cl defines _MSC_VER by ms-compatibility but BOOST_MSVC will not be set." still a problem? there are some Issues reported but i don't know if fixes are wanted of if there is a strategy to support clang-cl out of the box

(I am using Clang and GCC from this site with CodeBlocks IDE and also using b2/bjam but I could not get the clang-win .exe to build reliably and am using clang-linux .exe in my user-config.jam. However this isn't any help to your difficulties ☹ ). > compiler set to 2017 microsoft-cl in VS2017: > libboost_serialization-vc141-mt-gd-x32-1_74.lib > > compiler set to clang-cl in VS2017: > libboost_serialization-clangw10-mt-gd-x32-1_74.lib > > that behavior is new to 1.74 - older boosts versions 1.69..1.73 would use the vc141 libs what makes > sense because clang-cl is the microsoft-cl compatible replacement > > normaly there is no need to switch any external libs when using clang-cl instead of microsoft-cl

Re: [boost] Hello everybody, I have something to share about the shared_ptr class
by 逸霖杨 04 Aug '20

04 Aug '20

Last post was sent directly to Rob, I forgot to cc list.bost.org. Thinking of the multiple calling of the detors, which is suggested by Rob and other members, I came up with some ideas. This IS about specification. If class A has a dispose method like class A { A(){} ~A(){} //Dispose method: !A(){} }; Where !A() can be called multiple times and ~A() can be called only one time. Everything rcgc_ptr delegates will be called its dispose in !A() and therefore multiple times to just decrease the reference count and finally call ~A() when real delete happens. And this can be done on the compiler level (!A() maybe not visible at all or just visible when you use like ~A()). Saying this algorithm is a part of the C++ language itself, then C++ has no need to manually manage pointers (at least the unwanted management). Idea is inspired by all of you especially Andrey Janson and Rob. Thank you all! Best Regards, Yilin
