No success with VS2013 and Boost 1.55b1
by LeMay.Steve 22 Oct '13

22 Oct '13

Using the attached batch file (below) to make Boost 1.55 beta 1 - I did NOT have success building Boost 1.55b1 with the release version of VS2013. I was however on a different PC able to build Boost with successfully with this batch file using VS2012. Others have reported successful builds using VS2013 – am I missing something new?

Does boost::unordered_map<> work with boost::container::scoped_adaptor?
by Jonathon Bell 22 Oct '13

22 Oct '13

*context *our code base uses boost 1.54 with GCC 4.4.7 on CentOS 6, compiling as C++98. we're interested in using an allocator with state with the standard containers, so are investigating the boost container library in boost 1.54, in particular, instantiating these containers with a boost::container::scoped_allocator_adaptor<MyArena> style argument. *questions* 1) i notice that boost::unordered_xxx<> is not part of the boost container library. does this mean that these classes are not aware of the C++11 allocator model? a casual inspection of the code suggests that this might be the case 2) if so, has anyone here tried to patch them, port them, or the like? 3) if not, can anyone here offer thoughts or advice on how i might attempt to do so myself? rgerads, Jonathon Bell Paradigm 4

[Locale] linking against static ICU library
by Stathis 22 Oct '13

22 Oct '13

Hi, Is there a problem with building Boost.Locale against the static ICU libraries? I have quickly looked through the respective Jamfile, but I don't see it being supported. Could anyone give me a hint or two on how to modify the Jamfile to link against static ICU (they are prefixed with "s", e.g. sicuXXX.lib) ? Any help or ideas would be greatly appreaciated. regards, stathis

[MPL] How to generate pre-generated header files for lists containing more than 50 entries?
by Klaus.Kempf＠industronic.de 22 Oct '13

22 Oct '13

Hello MPL experts, I want to code a state machine which has a reaction list containing more than 50 entries. I found here [http://svn.boost.org/svn/boost/trunk/libs/mpl/preprocessed/] some python scripts to generate header files for lists containing more than 50 entries. But I cannot manage to generate a single header file. Can someone please explain to me how to use these scripts? I also didn't find any help in boost documention. Command line messages of the related script were also not helpful for me: preprocess_list.py Usage: preprocess_list.py <mode> <boost_root> [<source_file>] Purpose: updates preprocessed version(s) of the header(s) in "boost\mpl\list\aux_\preprocessed" directory Example: the following command will re-generate and update all 'apply.hpp' headers: preprocess_list.py all f:\cvs\boost apply.cpp What is the meaning of [<source_file>] here? And how/where do I have to specify the count of list entries in order to generate the header files "list60.hpp", "list70.hpp" and so on? Thanks for any help you could provide. Regards, Klaus

String algorithm? Removing non-alphanumerics from a string
by Tim Burgess 22 Oct '13

22 Oct '13

Hi, Takeing an std::string as input, I need to return the same string with any characters not in the ranges "az", "AZ" and "09" being discarded. A colleague told me that a could use something in the string algorithm library, but I'm obviously not spotting what I need. I tried regex replace, but failed, as I'm not understanding regular expressions yet. Any and all suggestions would be gratefully received. Best wishes. Tim Burgess

thread: linux fedora .so built file under c++98 does not provide start_thread() symbol
by MM 21 Oct '13

21 Oct '13

hello, I am compiling my code with g++4.8.1 under c++11 mode, however the fedora's system provided boost thread lib has been compiled under c++98. Linking fails because of errors like: mainthread.cpp:(.text+0x2cf): undefined reference to `boost::thread::start_thread()' mainthread.cpp:(.text+0xcc9): undefined reference to `boost::thread::join()' looking at the provided shared object, nm -C -D /usr/lib64/libboost_thread-mt.so.1.53.0 |grep start_thread 000000000000ba80 T boost::thread::start_thread_noexcept(boost::thread_attributes const&) 000000000000ba00 T boost::thread::start_thread_noexcept() neither of which is start_thread() I've put an entry here https://bugzilla.redhat.com/show_bug.cgi?id=1021009 Is there a possible workaround?

ASIO receive and handle uploaded files
by Caroline Beltran 21 Oct '13

21 Oct '13

I hope that someone can give me a very general overview of what I would need to do order to create an ASIO application that handles uploaded files. At this time, I am uploading files via my web browser to a PHP script that handles files. >From what I've read so far, I am guessing that I would have to create an ASIO server that listens for incoming HTTP POST (multipart/form-data) and saves the message to a file on the server. Any additional information would be much appreciated as well as pointing me to a relevant ASIO example(s) that I should carefully look at. Thank you!

Migration from boost 1.49 to 1.54
by Sebastian Messerschmidt 21 Oct '13

21 Oct '13

Hi folks, We have a rather big project which we like to migrate from boost 1.49 to 1.54. I ran into several compile problems under Visual Studio 2010 SP1. The most annoying I was not able to solve yet is the following: We are using boost::serialization a lot and I now get the following error: <snip> error C2995: 'boost_132::shared_ptr<T> boost_132::dynamic_pointer_cast(const boost_132::shared_ptr<U> &)' : function template has already been defined </snip> I checked the sources but I don't understand why this broken with the new version. I removed all references to "shared_ptr_cast" and dynamic_ptr_cast in my code, but compilation still fails. Any ideas? cheers Sebastian

C++Now 2014: Call for Submissions
by Hartmut Kaiser 20 Oct '13

20 Oct '13

============================================== C++ Now Conference 2014 Aspen CO, USA, May 12-17, 2014, www.cppnow.org ============================================== Call for Submissions -------------------- We invite you to submit session proposals to the 2nd annual C++ Now Conference (Aspen CO, USA, May 12-17, 2014). Building upon the resounding success of C++ Now 2013 and five years of BoostCon, C++ Now 2014 will present leading speakers from the whole C++ community. The C++ Now Conference is dedicated to discussion and education about C++, an open and free language and standard. Our Conference will focus on discussion and education about open source software usage and developments in the C++ developer and user community. To reflect the breadth of the C++ and Boost communities, the conference includes sessions aimed at three constituencies: C++ and Boost end-users, hard-core Boost library and tool developers, and researchers pushing the boundaries of computation. The program fosters interaction and engagement within and across those groups, with an emphasis on hands-on, participatory sessions. As a multi-paradigm language, C++ is a melting pot where the most compelling ideas from other programming communities are blended in powerful ways. Historically, some of the most popular sessions at C++ Now have highlighted these concepts, from DSLs to functional programming to transactional memory and more. Bring your C#, Python, Ruby or Haskell influences to bear in an environment that will broaden their exposure. At C++ Now 2014 we would like to focus on the now established C++11 standard and the new, upcoming C++14 and how those standard are and will shape C++'s future. However, by no means this is intended to restrict the topics of proposals we hope to see. Any other topic related to C++ as outlined below is perfectly fine for submission. Important dates --------------- New proposal submissions due: December 8th, 2013. Proposals decisions sent (tentative program available): January 30th, 2014. Fully scheduled program available: February 24th, 2014. Best Presentation Awards ------------------------ We know how much effort it takes to prepare talks for our conference. For this reason we will award the best presentations in the following categories: Best Presentation, Best Short Presentation, Best Tutorial, and Best Workshop. The awards will be given based on the audience's voting. Each award will include the author's name listed on the cover of the C++ Now website for that year and a plaque containing all the C++ Now conference information. Session topics -------------- Topics of interest include, but are not restricted to, the following: * C++11/14 and how it changes life for users and library writers * General tutorial sessions on C++11/14, the C++11/14 Standards library, and one or more Boost libraries * Parallelism in the new C++11/14 standard * Parallel, distributed and GPGPU topics relating to C++ * In-depth sessions on using specific Boost libraries * Case studies on using Boost * Experts panels * Advanced sessions on implementation techniques used within Boost libraries * Development workshops to extend or enhance existing Boost libraries * Workshops on design process * Infrastructure workshops such as Build tools, Website, Testing * Concepts and Generic Programming * Hardware and infrastructure presentations focused on how libraries can make better use of the technology * Software development tools and their application to C++ and or Boost * Other topics likely to be of great interest to C++ users and developers Interactive and collaborative sessions are encouraged, as this is the style of learning and participation that has proven most successful at such events. Sessions can be tutorial based, with an emphasis on interaction and participant involvement, or workshop based, whether hands-on programming or paper-based, discussion-driven collaborative work. Session formats --------------- Presentations Presentations focus on a practitioner's ideas and experience with anything relevant to C++11 or C++14, Boost and users. Panels Panels feature three or four people presenting their ideas and experiences relating to C++11 or C++14 and Boost's relevant, controversial, emerging, or unresolved issues. Panels may be conducted in several ways, such as comparative, analytic, or historic. Tutorials Tutorials are sessions at which instructors teach conference participants specific skills relevant to C++11 or C++14 and Boost. Workshops Workshops provide an active arena for advancements in Boost-relevant topics. Workshops provide the opportunity for experienced practitioners to develop new ideas about a topic of common interest and experience. Author's Corner Presentations These were introduced at BoostCon 2008, and were a great success. They are short (30 minute) sessions, focusing on tips on usage and design. In addition, we're looking to uncover the hidden design gems in Boost libraries. Tool Vendors Presentations We actively encourage tool vendors and ISP's to submit proposals for a special Tool Vendors Session Track aimed at products related to Boost and C++ (compilers, libraries, tools, etc.). Other formats may also be of interest. Don't hold back a proposal just because it doesn't fit into a pigeonhole. Submitting a proposal --------------------- Standard Sessions are 90 minutes. You may submit a proposal for fractions or multiples of 90-minutes. Fractional proposals will be grouped into 90 minute sessions covering related topics. Longer sessions, such as tutorials and classes, will be assigned three hour (i.e. half day), or six hour (i.e. full day) time slots. Please include: * The working title. * Type of session: presentation, panel, tutorial, workshop, authors corner, vendor track, other. * A paragraph or two describing the topic covered, suitable for the conference web site. * Proposed length: 10-20 minute short talks, 45 minutes, 90 minutes, half day, full day. * Alternate lengths, if you are willing to make adjustments: 10-20 minute short-talks, 45 minutes, 90 minutes, half-day, full day. * Audience: users, developers, both. * Level: basic, intermediate, advanced. * A biography, suitable for the conference web site. * Your contact information (will not be made public). Submission details ------------------ All submissions should be made through the EasyChair conference management system: http://www.easychair.org/conferences/?conf=cppnow2014. If you have not already registered at EasyChair, you will need to do so in order to submit your proposal. All submissions will go through a peer review process. Authors are invited (but are not required) to submit PDF versions of full papers of up to 10 pages in ACM conference proceedings format (see http://www.acm.org/sigs/publications/proceedings-templates) The full papers are not required unless you want them published in the proceedings. All accepted proposals will be made available in the Association for Computing Machinery (ACM) Digital Library (approval pending). Best papers, after further reviews, will be considered to be book chapters or journal articles in a renowned journal. The session materials go on the C++ Now website and will be available to attendees. For general information on the C++ Now 2014 paper submission or the scope of technical papers solicited; please refer to the conference website at www.cppnow.org. For any other questions about the submission process or paper format, please contact the Program Committee at cppnow2014(a)easychair.com.
