boost-1.66.0 tag?
by James E. King, III 18 Dec '17

18 Dec '17

I just refreshed Boost.Uuid locally and don't see a boost-1.66.0 tag. I had assumed this would be added by the upstream build and release procedure? Am I supposed to make that tag? - Jim

[chrono][timer][release] Non-inline functions in inlined headers
by Daniel James 14 Dec '17

14 Dec '17

Hi, We've had a link problem reported. for this code on Visual Studio, using auto-linking: #include "boost\chrono.hpp" #include "boost\timer\timer.hpp" int main() { auto now = boost::chrono::steady_clock::now(); boost::timer::cpu_timer cput; return 0; } I haven't got the binaries installed yet, so I haven't reproduced it, but I think it's caused because timer now includes the chrono headers using BOOST_CHRONO_HEADER_ONLY, and in the chrono inlined headers not all functions are BOOST_CHRONO_INLINE. It looks like this problem was always in chrono, but BOOST_CHRONO_HEADER_ONLY was widely used enough for it to be detected. I'd quite like to fix this for 1.66.0, which requires either reverting the change to timer, or fixing the problem in chrono. The error is in chrono, but I'm more inclined to revert the change in timer for this release, as it's a less disruptive way of quickly fixing the problem. https://github.com/boostorg/timer/pull/5

Building only x86 /MDd and /MT on msvc 2017
by Fredrik Stax{ng 13 Dec '17

13 Dec '17

The docs says For instructions on how to build only specific variants, please ask on the Boost.Build mailing list. but I gmane gives a 411 for Boost.Build so I ask the question here. For 1.60.0 I used this cd modular-boost rem call .\bootstrap .\b2 headers .\b2 toolset=msvc variant=debug address-model=32 link=static threading=multi runtime-link=shared .\b2 toolset=msvc variant=release address-model=32 link=static threading=multi runtime-link=static Has this changed? -- Fredrik Stax\"ang | rot13: sfgk(a)hcqngr.hh.fr This is all you need to know about vi: ESC : q !

[beast] Security
by Phil Endecott 13 Dec '17

13 Dec '17

Dear All, To what extent do we think that Beast should be "secure"? I am thinking mostly about handling malicious input. Has it been reviewed by anyone with specific experience of how HTTP can be attacked? Has it been "fuzzed"? Regards, Phil.

linker error in 1.66 rc1 (regression from 1.65.1)
by Mark Incley 13 Dec '17

13 Dec '17

Hi, Using Visual Studio 2017 15.5, the following minimal test case causes a linker error with Boost 1.66 RC1 but builds fine with 1.65.1: Produces... 1>------ Build started: Project: aZ80, Configuration: Debug Win32 ------ 1>libboost_timer-vc141-mt-gd-x32-1_66.lib(cpu_timer.obj) : error LNK2005: "public: static class boost::chrono::time_point<class boost::chrono::steady_clock,class boost::chrono::duration<__int64,class boost::ratio<1,1000000000> > > __cdecl boost::chrono::steady_clock::now(void)" (?now@steady_clock@chrono@boost@@SA?AV?$time_point@Vsteady_clock@chrono@boost@@V?$duration@_JV?$ratio@$00$0DLJKMKAA@@boost@@@23@@23@XZ) already defined in libboost_chrono-vc141-mt-gd-x32-1_66.lib(chrono.obj) 1>libboost_timer-vc141-mt-gd-x32-1_66.lib(cpu_timer.obj) : error LNK2005: "double __cdecl boost::chrono::chrono_detail::get_nanosecs_per_tic(void)" (?get_nanosecs_per_tic@chrono_detail@chrono@boost@@YANXZ) already defined in libboost_chrono-vc141-mt-gd-x32-1_66.lib(chrono.obj) 1>C:\Projects\aZ80\vs\Debug\aZ80.exe : fatal error LNK1169: one or more multiply defined symbols found Swapping the order of the includes appears to workaround the problem.

Info: Boost.Config is older than your compiler version - message is surprising
by Paul A. Bristow 11 Dec '17

11 Dec '17

I've just updated to the latest and greatest Visual Studio 15.5 and also got my Boost develop branch up-to-date. But I'm still getting this message: "Info: Boost.Config is older than your compiler version - probably nothing bad will happen - but you may wish to look for an updated Boost version. Define BOOST_CONFIG_SUPPRESS_OUTDATED_MESSAGE to suppress this message." I've just rebuilt my library files that have the new -x64- x32 in the name (great - but grrrr because I have had to change all my command files to generate them, previously in /x64 and /win32 folders ;-) The library files have names like libboost_chrono-vc141-mt-x64-1_66.lib so version number is still at 1.66 (a fact confirmed by the config_info Boost version 106600) The config_info.txt output is attached. So I am surprised to get this potentially useful warning. It would *much* more helpful if the warning told which version number of both compiler and Boost? (Just like the 'File not found' message that provokes "Which *&%$%^!!ing file" expletives). Paul PS The Good news is that defining BOOST_CONFIG_SUPPRESS_OUTDATED_MESSAGE quiets as promised. --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830

Help requested for boost documentation for polymorphic_value
by Jonathan Coe 11 Dec '17

11 Dec '17

I have been preparing polymorphic_value for submission to boost. I have draft documentation here: https://drive.google.com/open?id=1xpD8s8zDzedVDDlqjsl1JtYGaJBHWoGy but am having problems generating doxygen docs. A forward declaration seems to stop generation of docs for methods of polymorphic_value. I'm at a loss as to why doxygen is not working properly for boost doc (it works fine when run in isolation) and would be grateful for any insight anyone can offer. I suspect it's a simple problem but I'm not very experienced with doxygen and am new to the boost docs tools. source is here: https://github.com/jbcoe/polymorphic_value/tree/boost regards, Jon

Optional third-party libraries
by James E. King, III 09 Dec '17

09 Dec '17

The boost documentation on the web site talks about building boost from source, but I don't see information on how to leverage optional third party libraries easily accessible in the documentation from the place the user will most likely end up: "Building From Source". This information seems to be tucked away in documentation of various components, making it difficult to actually build a complete boost. I think it would be a good idea to bring this information up to the top level build instructions, at the very least itemize these third party packages and then link to the relevant project-specific documentation pages that talk about configuring to use them. Here are the third party optional libraries I know about so far and the libraries that use them: bzip2 (iostreams) iconv (locale - if icu not available) icu (locale, regex) lzma (iostreams) openssl (asio, beast) pthread-win32 (sync, thread) zlib (beast, gil, iostreams) Any others? Would folks find it useful if this information was part of the standard "Building From Source" sections of the upper layers of documentation? Thanks, Jim

[config] msvc-15.5, updating tests
by John Maddock 09 Dec '17

09 Dec '17

While working on updating Boost.Config for msvc-15.5 I've managed to break the test case for boost_no_cxx17_iterator_traits (both GCC and msvc agree on this) but can't see what's wrong :( The change is this one: https://github.com/boostorg/config/commit/305f5a58ef879037b0fd9fdaa8e05615c… which removes use of std::iterator as a base class. Anyone any ideas? Many thanks, John. --- This email has been checked for viruses by AVG. http://www.avg.com
