by dinesh kumar 16 Nov '18

Hi Team, I would like to take this to your notice, as the boost process group object creation is failing, in windows with ${SUBJECT} versions. I've tried 1.66, 1.69-b1-canadiate2 both are working fine. #include <boost/process.hpp> #include <iostream> int main() { try { boost::process::group grp; } catch (std::exception &e) { std::cout << e.what(); } return 0; } *Output* SetInformationJobObject() failed: The handle is invalid. Visual studio version is: 15.8.5 -- Regards, Dinesh manojadinesh.blogspot.com

[Optional] Lazy initialized optional
by Michael Powell 14 Nov '18

14 Nov '18

Hello, I am looking into deriving from boost::optional and adding lazy initialization capability. I can arrange a constructor, or whatever, to inject an appropriate factory method, functional callback, etc, that's no problem. >From the boost::optional perspective, I'd like to override a key method (or methods, hopefully not too many) in order to inject that factory provided value. I'm thinking optional::get? Unless there's a better override for that? Cheers, Michael Powell

Hello, What's the minimum implementation a struct needs to fulfill in order to be boost::variant friendly? Things like, does it need to support perfect forwarding? An assignment operator? And so on. Thanks! Michael Powell

[Spirit] Qi int_parser rejecting a negative signed std::intmax_t
by Michael Powell 12 Nov '18

12 Nov '18

Hello, qi::int_parser works fine for a positive signed hex radix integer, but is failing for a negative signed hex radix integer. My integer type is std::intmax_t, which on this platform I think is long long. Is there an integer width constraint? And/or a signage problem? Do I need to enable BOOST_HAS_LONG_LONG? Or is that enabled by default? Cheers, thanks! Michael Powell

Boost 1.68.0 contains only python 3.7 library, no python 2.7 library?
by Heng Zhou 10 Nov '18

10 Nov '18

Hi, I installed Boost 1.68.0 recently from Windows x64 pre-compiled binary "boost_1_68_0-msvc-14.0-64.exe" downloaded from https://urldefense.proofpoint.com/v2/url?u=https-3A__sourceforge.net_projec…. Then, I noticed that this version of Boost contains only python 3.7 library because the filenames under C:\local\boost_1_68_0\lib64-msvc-14.0 are only boost_python37-vc140-mt-.... This caused errors from building a third-party library which tries to link Boost python 2.7 library (i.e., tries to find file boost_python27-vc140-mt-...) . So what is matter? Does Boost decide to stop supporting python 2.7 since version 1.68.0, or is Boost python 2.7 library located somewhere else using some hard-to-recognize filename? I'm using Windows 10, VS2015 and have only python 2.7 installed. Thank you for your help with this issue.
