New boost webpage
by Marcin Kalicinski 18 Aug '05

18 Aug '05

Hi all, I know gazillion words have been said on the looks of the new webpage, but still I want to add my 2 pennies. Briefly, I think that links in the text look very ugly and... amateurish? If you insist on having them underlined I suggest you stick with more standard look, such as on OpenOffice.org webpage (and many others). This looks much more professional. Additionally, I'd rather have links in boxes on the right have the same style as links in the text. cheers, Marcin

Errors in warning texts when building boost 1.33
by Jurko Gospodneti� 18 Aug '05

18 Aug '05

Hi all. Not sure if anyone reported this or if it is fixed in the CVS but when you build the 1.33 boost release on a machine with none of the additional software needed to use the IOStreams zipping functionality the warning displayed (the first one) seems to have a typo... it seems to come out in one line instead of two and one of the bjam 'ECHO' commands gets displayed as well. Hope this helps, Jurko Gospodnetiæ

MSVC 7.1 warnings for lexical_cast.hpp
by Jurko Gospodneti� 18 Aug '05

18 Aug '05

Hi all. I was wandering if someone could disable the following warnings for the lexical_cast.hpp file when compiled with the MSVC 7.1 compiler: * 4511 - Copy constructor shall not be generated. * 4512 - Assignment operator could not be generated. * 4127 - Conditional expression is constant. They are reported at high warning reporting levels and easy to work around by preparing my own wrapper header that disables them but I would really like it if boost could do this out-of-the-box. Best regards, Jurko Gospodnetiæ

hi guys, I got problems with compiling the new release for MS Visual Studio 7.1 on winXP. I download the boost self extracting exe for win and the pre-build version of bjam for nt machines and I tried to build it with E:\boost_1_33_0>bjam -sVC71_ROOT="E:\programme\Microsoft Visual Studio .NET 2003 " -sTOOLS=vc-7_1 install to compile it bud I just become this output: ****************************************************** Building Boost.Iostreams with bzip2 support disabled. ECHO To enable bzip2, cons ult the Boost.Iostreams documentation ****************************************************** ****************************************************** Building Boost.Iostreams with zlib and gzip support disabled. To enable zlib and gzip, consult the Boost.Iostreams documentation ****************************************************** Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (and if you don't know what ICU is then you probably don't need it).

surveying async network io libraries
by Jose 18 Aug '05

18 Aug '05

Hi, Pardon my high level focus as I am new to the list. I have read all the multiple threads on this topic and I only want to confirm understanding of what libraries can be used now or in a few months, before a future boost library is available. Authors please jump to provide info on your release plans (if possible). I define the library as a c++ async network io library (at least linux ready now but multi-platform in the future) at the connector / acceptor level (or higher but never at the sockets level) that can be combined in different concurrency models (e.g. single-threaded or multi-threaded where the async network io can run in one or multiple threads). I'll just list a brief pro/con list for the 3 libraries I've found so far nanostreamer (downloaded from the boost vault) ========== pros - good introductory article.pdf - designed to make best use of c++ and boost (my newbie opinion!) - real world code examples, e.g. http server (although not fully developed) cons - no async network io available yet although it is planned (see event queue ext) asio (asio.sf.net) === pros - async network io ready (linux epoll as of 0.31) cons - basic real world code examples (but no http examples) - does not use boost threads netiphany (netiphany.sf.net and boost vault) ======= pros - simple usage (see rfc doc in the vault archive, by Don G) - focused on async network io (not sure how it can be combined with threads) cons - no implementation distributed yet (although mentioned and partially shown in the sf docs) Note that I've not included sockets wrappers or libraries that will not provide an async network io solution in the short term. Also worth checking the scheduler library in cryp.to and the CUJ dec 2002 article on a templated library for fast multiplexing although both of those don't seem to have active development. Thanks and regards Jose

Re: [boost] Propose adding Clone Smart Pointer (clone_ptr) to the boost library

What I meant is that both allow a user to implement a container of heterogeneous objects. The documentation needs to explain when the user should choose one over the other (they must offer different trade-offs). I was about to say "Just as the documentation compares and constrasts boost::any and boost::variant." However it turns out that it doesn't!

I agree. I think that clone_ptr is designed for a rather small niche, and I can't see myself ever needing it ... but that doesn't mean it couldn't be useful to somebody. -- Martin Bonner Martin.Bonner(a)Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 441434
