Boost 1.70 - Test library error on Sun Solaris Studio 12.3
by mik 11 Dec '19

11 Dec '19

Hi, I'm triying to compile the boost 1.70 on Sun solaris using the version 12.3, but I got an annoying error on the test library: "./boost/test/unit_test_log_formatter.hpp", line 39: Error: Identifier expected instead of "__global". For what I can understand it seems that compiler doesn't recognize the keyword __global. Below, there's the command line that I've used: ./b2 toolset=sun variant=debug address-model=64 threading=multi link=shared runtime-link=shared --with-test Do you have any suggestions? Thanks, Mirko

[review][fixed_string] FixedString review starts today
by Joaquin M López Muñoz 05 Dec '19

05 Dec '19

The Boost formal review of Krystian Stasiowski and Vinnie Falco's FixedString library starts today November 25 and extends up to December 4. Description FixedString provides a dynamically resizable string of characters with compile-time fixed capacity and contiguous embedded storage in which the characters are placed within the string object itself. Its API closely resembles that of std::string. Repo and docs GitHub repository: https://github.com/18/fixed_string Online docs: https://18.github.io/doc/fixed_string Review questions Here are some questions you might want to answer in your review: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain? And finally, every review should answer this question: - Do you think the library should be accepted as a Boost library? I invite you to submit your review, either publicly to the developers or the users lists, or else, if for whatever reason you don't want to go public, directly to me. Thank you for investing your time on reviewing Krystian and Vinnie's work and for contributing to the advancement of Boost. Best regards, Joaquín M López Muñoz Review manager for candidate Boost.FixedString

Is it possible to force the boost::propertytree::write_json method to write the entire json tree on a single line (not human readable at all but to save file size)? Sent with [ProtonMail](https://protonmail.com) Secure Email.
