[Serialisation] Using wide character
by Vincent Capicotto 25 Feb '11

25 Feb '11

Hi, first sorry for my bad English. I try to use wide characters with archive to serialize into xml, and I don't know the good way to do this. Until now, we used serialization with ASCII characters and it works fine. This is the part of the code for the ASCII: *std::ifstream oInputStream(szXmlDefinition.c_str()); boost::archive::xml_iarchive oXmlInputArchive(oInputStream); oXmlInputArchive >> SERIALIZE_MEMBER(szNomObjet, oObjet );* For the UNICODE I try to use wiarchive like this : *std::wistringstream oInputStream(szXmlDefinition.c_str()); boost::archive::xml_wiarchive oXmlInputArchive(oInputStream); oXmlInputArchive >> SERIALIZE_MEMBER(szNomObjet, oObjet );* but Visual C++ 2005 doesn't find xml_wiarchive during the link operation. Is it the good way to use wides character with archive and serialisaztion or not ? Please helpe me :) Thx This email is confidential.

License information

Hi All, I have read the boost license and I think I can do what I need, but to be sure I prefer to ask your opinion. I'm working at a very small project and I would like to keep the dependencies to external library as more contained as possible. I'm now in the situation where I need boost::any class... Do you think I can simply take the boost/any.hpp file, including both license and author copyright and modify it to make it compile in my project. Am I violation the license if I do so? Thanks for your time, Dan

input format library
by Daniel Neuberger 24 Feb '11

24 Feb '11

Is there any work being done on an input format library for Boost? Something similar to Boost.Format but for input rather than output? Google tells me that this has been discussed before, but I couldn't find any resolution of the issue. I'm interested because I need something like sscanf, but want it to be more powerful and safer (like Boost.Format vs. fprintf). I know there are workarounds using Boost.Spirit, Boost.Regex, std::istream, and boost::lexical_cast, but in my mind, none of those are a complete solution for this problem. Thanks. - Daniel

using the sandbox(es)
by Alle Meije Wink 24 Feb '11

24 Feb '11

Dear all, My code uses some files from the boost sandbox repository as well as from boost. To be able tom compile my own code and stay up to date, I have downloaded and installed boost (svn, bjam) and downloaded the sandbox (svn). Now building boost was simple: create a build/ directory and call "bjam -a --toolset=gcc --build-dir=build --variant=release --link=shared --threading=multi --runtime-link=shared install" or something very similar In the sandbox things seem to be a bit differently. Using bjam in the same style as above does not work, in particular any "bjam ... install" comes back with a warning/notice notice: could not find main target install notice: assuming it is a name of file to create. don't know how to make <e>install ...found 1 target... ...can't find 1 target... and no files are installed (i.e. no files are copied to /usr/local/include). Is it possible to install the boost-sandbox files to /usr/local using bjam? Or is this not the way the sandbox should be used? many thanks Alle Meije Wink

[boost][boost-users][ICL] ICL Compilation errors. Ticket #5207
by Joachim Faulhaber 24 Feb '11

24 Feb '11

Hi John, lists, I am replying to your ticket #5207 on the lists because I am afraid that you walked into a trap that others can fall into as well. In the ITL, the precursor of Boost.ICL there was a single polymorphic interval class template: itl::interval. Due to input from the list during the review I split up this "one size fit's all" template in smaller classes according to static and dynamic interval concepts. In order to help ITL users to have a simple transition from ITL to ICL I wrote a template icl::interval. icl::interval is a meta function that yields the right interval type dependent on the instance type e.g. : BOOST_STATIC_ASSERT(( boost::is_same< interval<int>::type , discrete_interval<int> >::value )); So ITL users could move from ITL to ICL just by appending a '::type' to all occurrences of 'interval<T>' So please note that interval<myType> myInterval; can not be used as an interval type in ICL functions. Please use interval<myType>::type myInterval; or one of the specific interval types discrete_interval, continuous_interval, (dynamic borders) closed_interval, right_open_interval, left_open_interval, open_interval (static borders) e.g. discrete_interval<int> myInterval; See examples http://www.joachim-faulhaber.de/boost_icl/doc/libs/icl/doc/html/boost_icl/e… http://www.joachim-faulhaber.de/boost_icl/doc/libs/icl/doc/html/boost_icl/e… http://www.joachim-faulhaber.de/boost_icl/doc/libs/icl/doc/html/boost_icl/e… and docs http://www.joachim-faulhaber.de/boost_icl/doc/libs/icl/doc/html/boost_icl/i… for more detail. This reduces John's non compilable ICL statements in the following way: BOOST_AUTO_TEST_CASE(ticket_5207) { icl::interval< int >::type int_interval; icl::interval_set< int > int_set; icl::interval_map< int, int > int_map; icl::interval_map< int, int >::element_type int_element; icl::interval_map< int, int >::segment_type int_segment; // The next 4 lines compile icl::lower( int_interval ); icl::upper( int_interval ); icl::first( int_interval ); icl::last( int_interval ); // The next 4 lines are *not* supposed to compile // according to the docs: icl::add( int_set, int_set ); icl::add( int_map, int_map ); icl::subtract( int_set, int_set ); icl::subtract( int_map, int_map ); int_set += int_interval; // compiles // Here you are right, John: // The next 4 lines should compile according // to the docs, but don't icl::disjoint( int_map, int_element ); icl::disjoint( int_map, int_segment ); icl::intersects( int_map, int_segment ); icl::intersects( int_map, int_element ); // Those four are pretty special. I doubt anyone will // use them. But I will complete the library here. } Thanks for using my library and helping to improve it.

Undefined reference to boost_serialization even though it is specified with -lboost_serialization
by Cedric Laczny 24 Feb '11

24 Feb '11

Sorry, my bad. Hit "Send" before being finished... So let's start again... I apologize. Hi, I have a program that uses serialization-functionality for some of the self- defined classes. I specify "-lboost_serialization" with the g++ and it works fine on my local machine. However, when I want to compile it on a remote machine, it fails. The remote machine is lacking >=boost-1.42 which is needed. Therefore I built (no install) boost-1.45 remotely (under /local/cedric/boost_1_45_0) and at least the configure-script (generated using autotools) seems to detect all the necessary libraries and headers (provided I specify them in the environment variables), on my local machine aswell as on the remote machine. Now the problem is, that I don't find the reason why it fails to compile my program remotely... Any ideas? Here's the command used for linking: /bin/bash ../libtool --tag=CXX --mode=link g++ -Wno-deprecated -g -O2 - lboost_serialization -L/local/cedric/boost_1_45_0/stage/lib -o test test- main.o ../includes/Parser/libparser.a -lgsl -lgslcblas -lm and an excerpt of the error (taken from the end): ...

Help needed with successive calls to Asio routines using the plain old Windows API
by Adolfo Jimenez 24 Feb '11

24 Feb '11

Hi all: Using MS Visual Studio 2008 C++ for Windows 32 (XP brand), I try to construct a POP3 client managed from a modeless dialog box. As a first step, in the WM_INITDIALOG message in the dialog-box-procedure, I create a persistent object -say pop3- with all that Boost.asio stuff to do asynchronous connections. Some like: case WM_INITDIALOG: return (iniPop3Dlg (hDlg, lParam)); Here we assume that iniPop3Dlg() create the pop3 heap object -say pointed out by pop3p-, and then, connect with the remote server and initiate a session with the client’s id and password (USER and PASS commands). After that, the server is in TRANSACTION state. Then, in response to some user input, the dialog-box-procedure, call the appropriate function. Say: case IDS_TOTAL: // get how many emails in the server total (pop3p); return FALSE; case IDS_DETAIL: // get date, sender and subject for each email in the server detail (pop3p); return FALSE; Note that total() uses the POP3’s STAT command to get how many emails in the server, while detail() uses two commands consecutively; first STAT to get the total and then a loop with the GET command to retrieve the content of each message. As an aside: detail() and total() share the same subroutines -the STAT handle routine-, and when finished, both leaves the session as-is. That is, without closing the connection; the socket remains opened an the server in TRANSACTION state. When any option is selected by the first time, the things run as expected, obtaining the desired results. But when making the second chance, the connection hangs. A closer inspection show that the in the second chance, the first time that is use the statement socket_.get_io_service().run(); It never return. Note that all asynchronous wirte an read routines uses the same io_service, and the socket_.get_io_service().reset(); sentence prior to any io_service.run() Note also that all R/W operations also uses the same timer, who is reseted to cero wait afther each operation is completed: dTimer_.expires_from_now (boost::posix_time::seconds(0)); I suspect that the problem is in the io_service or in the timer, and the fact that subsequent executions occurs in a different load of the routine. As a first approach to mi problem, I hope that someone would bring some light in it, prior to a more detailed exposition of the -very few and simple- Asio routines involved.
