[Test] Can't build Boost Test 1.65.0 with Visual Studio 2013
by Kerry, Richard 07 Sep '17

07 Sep '17

I've just tried building Boost Test 1.65.0 with Visual Studio 2013 (ie msvc-12) and it doesn't seem to work, showing a compiler internal error. Can anyone advise what I might be doing wrong. Or whether a newer (or older) release fixes this issue. I've also tried 1.64.0 with an identical looking failure. Details below. Regards, Richard. I run : >b2 --with-test (as in the docs, though I'm not specifying address-model, link, --prefix or install. Having tried address-model and link as documented they appear to show the same fault). And then, after some messages, including "- test : building" (and nothing else listed as building), I get some messages starting: ...patience... ...found 1239 targets... ...updating 28 targets... compile-c-c++ bin.v2\libs\chrono\build\msvc-12.0\debug\link-static\threading-multi\chrono.obj chrono.cpp C:\Users\kerryr01\Downloads\Boost\boost_1_65_0\boost/type_traits/common_type.hpp(43) : fatal error C1001: An internal error has occurred in the compiler.

flat_(multi)map/set and Compare::is_transparent
by TONGARI J 06 Sep '17

06 Sep '17

Hi, Since C++14, the standard introduces transparent comparators for heteregeneous lookup, but seems that the Boost's flat counterparts don't take advantage of this yet. Is there any plan to support transparent comparators? Thanks.

[fiber][asio] Problem running http://www.boost.org/doc/libs/1_65_0/libs/fiber/examples/asio/autoecho.cpp
by Mark Hieber 24 Aug '17

24 Aug '17

Hi, I am using cmake 3.9.1 and Boost 1.65.0. I have downloaded the autoecho.cpp file and the corresponding yield.hpp, detail/yield.hpp and round_robin.hpp from http://www.boost.org/doc/libs/1_65_0/libs/fiber/examples/asio. When I run my program (just these 4 files, with no modifications), I get this output: Thread A: started Thread A: A0: echo-server started Segmentation fault Using print statements the seg-fault happens in the io_svc->run(); call. If anyone can help me with this, I would appreciate it. BTW, I am running on Ubuntu 16.04.3 LTS Thanks, Mark

Portable file I/O with system error codes support
by Oleg Andriyanov 23 Aug '17

23 Aug '17

Hi, I'm looking for a portable way to open a file, read some data from it, and do a proper error reporting in case of error. Apparently std::fstream is not suitable for this task because it does not provide means to retrieve original error code or even some human readable description of what went wrong (checking errno does not count since the standard does not guarantee it is set by any functions in std::fstream). I'm wondering if boost::iostreams can do that, but I've found nothing this far that could help in getting the error code. I've also tried boost::filesystem::fstream, but no luck. Users of large frameworks like Qt have advantage of their portable wrappers for file I/O like QFile. Are there any means in Boost which provide similar functionality? Related StackOverflow question: https://stackoverflow.com/questions/45840686/portable-way-to-read-a-file-in… Thanks.
