linking problem with Visual Studio 2005
by Andrea Galeazzi 18 Dec '07

18 Dec '07

Hi everybody, I'm trying to use boost in a .NET project written in C++ managed. When I build it in Debug version it's everything alright, but when I do it in Release version I've got this error: error LNK2001: unresolved external symbol "char __cdecl boost::re_detail::w32_toupper(char,unsigned long)" (?w32_toupper@ re_detail@boost@@$$FYADDK@Z). In particular the error above is generated by the following row: regex_replace(std::string(p1, p2), transformer, replace_string,boost::format_all). So now I'm in a bind because I've completed my application but I cannot distribute it due to the fact that .NET allows to deliver only release version. Can some help me? Cheers

Jamfile to use system boost
by Darren Dale 18 Dec '07

18 Dec '07

Hi, I am new to boost, working through the quickstart example as documented at http://www.boost.org/libs/python/doc/building.html . I have gotten to the point where I can move the test project out of the boot source tree, and run the tests by directing the Jamroot back to the boost source tree. The next step I would like to take is to build the test project using my system's boost (version 1.34.1, installed using gentoo's package manager), rather than the svn checkout. This question has been asked on this list before, but was not resolved: http://www.nabble.com/-python--jam-file-to9942060.html#a9942060 . Is it possible to use boost without the boost source tree? If so, what should I look for so I can point my Jamroot to the right place? As it stands, I am stuck in the same place as the previous poster. If gentoo hasn't installed all of the necessary files, maybe I could improve gentoo's handling of the package. Thank you, Darren

Interprocess: which version to use?
by Michael Shepanski 18 Dec '07

18 Dec '07

Hello, I want to start using boost::interprocess. My needs are fairly modest, so I don't need a large feature set, but reliability is valuable. Also I need it to be compatible with the rest of boost 1.34.1. So which is the best version of interprocess for me to download and use? Thanks, --- Michael

Visual Studio .NET 2008 compiler #defines?
by legalize+jeeves＠mail.xmission.com 18 Dec '07

18 Dec '07

[Please do not mail me a copy of your followup] I'm using boost 1.34.1 with the Boost Consultants installer. I tried compiling some code with Visual Studio 2008 and of course 1.34.1 doesn't recognize the compiler and prints out a lot of "compiler not recognized" messages. The code seems to compile OK, but obviously the compiler isn't recognized. Are there plans to update the #defines to recognize VS.NET 2008 soon, or should I do something to update the headers? (Would this mean I'd have to recompile all the libs? I'm using the precompiled libs at the moment.) Thanks in advance. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

time_series
by Sebastian Weber 17 Dec '07

17 Dec '07

Hello everyone! I am wondering about the time_series library. It got accepted a while ago and I thought it will be included in boost 1.35.0. However, I can not find time_series in subversion - its not in the trunk, nor in sandbox or any other suspicious places. Only the quite old version in the sandbox on boost-consulting seems to be available. What happened? Can someone enlighten me, please? The library looks really useful and I am willing to use it in my project. Are there any alternatives by the way which can compete with boost.time_series and are as well written in C++? Greetings, Sebastian

Run-time flavors of Boost (aka lib suffix / runtime-options)
by Benoit Sigoure 17 Dec '07

17 Dec '07

Hello list, Boost libraries often ship compiled in various different "flavors" (compiled with different runtime-options). First off, is there an official place where this is documented? I didn't find any, besides the header `boost/config/auto_link.hpp'. Based on this header, I tried to document the suffix used by Boost libraries as follows: > A suffix is one or more of the following letters: sgdpn (in that > order). s = static > runtime, d = debug build, g = debug/diagnostic runtime, p = STLPort > build, > n = (unsure) STLPort build without iostreams from STLPort (it looks > like `n' > must always be used along with `p'). Additionally, it can start > with `mt-' to > indicate for multi-thread builds. Is this accurate? What is a `static runtime'? My guess is that `-s' is Windows-specific, because on Windows it's common to see both shared libraries and static libraries using the same naming scheme `libfoo.lib' (because in the shared library case, `libfoo.lib' is not a directly shared library but rather an import library), can anyone confirm that? This entails that for most UNIX-like OSes, the `-s' variant doesn't exist, it's the `libfoo.a' static archive that is used instead, is that correct?

BoostCon 2008: May 4-9
by David Abrahams 17 Dec '07

17 Dec '07

The 2nd annual Boost Conference has been scheduled for May 4-9 2008. Please save the date! Registration should open sometime in the next week. If you want to stay at the Aspen Meadows (highly recommended as it is within walking distance of the conference venue and was the site of great after-hours discussions in '07), it's especially important this year that you book your rooms early. Since, unlike last year, Aspen's airport will be open this May, demand for rooms has been heavy. In fact, the following week, which we tried to get, was snapped up by another group before we even had a chance to catch our breath, just weeks after BoostCon'07 ended. We'll be working hard on getting the program together for 2008 over the coming weeks. We hope to include many more Boost authors and contributors, and build in several more intensive library-specific sessions, to make 2008 better than ever. Please send any questions to the BoostCon planning committee at: boostcon-plan(a)lists.boost-consulting.com Those of you who didn't make it to BoostCon'07 may want to have a look at the photo gallery at http://boostcon.com/community/photos, peruse the 2007 program at http://boostcon.com/program, and check out the two trip reports mentioned here: http://boostcon.com/news/2007/Jul/16/yet-another-trip-report. See you in Aspen! -- The BoostCon Planning Committee

[review] Review of Unordered library begins today December 7
by Ion Gaztañaga 16 Dec '07

16 Dec '07

Hi all, The formal review of the Unordered library, proposed by Daniel James, begins today : *Description*: An implementation of the unordered containers specified in TR1, with most of the changes from the recent draft standards. *Author*: Daniel James *Download*: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam… The documentation is in the zip file. I've put documentation online here: http://igaztanaga.drivehq.com/unordered http://tinyurl.com/yw8wjp What to include in Review Comments ================================== Your comments may be brief or lengthy, but basically the Review Manager needs your evaluation of the library. If you identify problems along the way, please note if they are minor, serious, or showstoppers. 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? Be sure to say this explicitly so that your other comments don't obscure your overall opinion. Unordered containers are likely to become one of the most used Boost libraries so I encourage you to review the library in order to see if Unordered fulfills all your expectations.

[boost-users] tokenizer vs string algorithm split.
by chun ping wang 15 Dec '07

15 Dec '07

Hi I was wondering which one is better and faster to split a file of csv value of number and put it into container of double. 1.) Which option is better. // method 1. std::vector<std::string> split_string; boost::algorithm::trim(flist); boost::algorithm::split(split_string, flist, boost::algorithm::is_any_of(",")); std::vector<double> elements; BOOST_FOREACH(std::string s, split_string) { elements += boost::lexical_cast<double>(s); } // method 2. boost::char_separator<char> sep(","); boost::tokenizer<boost::char_separator<char> > tokens(flist, sep); std::vector<double> elements; BOOST_FOREACH(std::string token, tokens) { elements += boost::lexical_cast<double>(token); } 2.) When is it better to use string algorithm split instead of tokenizer and vice versa.
