regex_search all
by izua 18 Aug '07

18 Aug '07

Hi everyone! I'm Richard from romania, and I'm pretty new to boost. I started using it because I need regex functionalities. Is there a regex_search functionality that will show me all found entries for the given regular expression? Something like preg_match_all in PHP? For example, if i have a regex ([0-9]+?[\W]+?) and the search string "abcd123.ef56[tab]essn" it would return me 2 arrays of arrays: first with an array 123 and ., second with 56 and tab. Thanks. -- View this message in context: http://www.nabble.com/regex_search-all-tf4285608.html#a12199378 Sent from the Boost - Users mailing list archive at Nabble.com.

oarchive and woarchive in different headers
by Hector C. 18 Aug '07

18 Aug '07

Hi all, Why is it that boost::archive::binary_oarchive and binary_woarchive require different headers? Isn't this against the custom in other headers, e.g. both string and wstring are defined in <string>. -- Hector C. ---------------------------------- ____________________________________________________________________________________ Be a better Globetrotter.

Serialization library build problems
by Dominick Layfield 18 Aug '07

18 Aug '07

When I try to compile an application that uses the Boost serialization library, I get some compilation errors that I don't understand. I've taken the code, and trimmed it down to the simplest possible case that produces the same error. Here's the code: // Test of Boost serialization library #include <sstream> #include <boost/archive/text_oarchive.hpp> class test_t { public: int i; template <class Archive> void serialize(Archive& ar, const unsigned int version ) { ar & i; } test_t(int _i) : i(_i) {}; }; int main(void) { std::ostringstream oss; boost::archive::text_oarchive oa(oss); test_t test(1); oa << test; return 0; } When I compile this (gcc 4.1.2, Boost 1.33.1, under Fedora 7), I get the following error: g++ serialization_test.cpp -l boost_serialization /usr/include/boost/archive/detail/oserializer.hpp: In function ‘void boost::archive::save(Archive&, T&) [with Archive = boost::archive::text_oarchive, T = test_t]’: /usr/include/boost/archive/basic_text_oarchive.hpp:78: instantiated from ‘void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = test_t, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/detail/interface_oarchive.hpp:78: instantiated from ‘Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = test_t, Archive = boost::archive::text_oarchive]’ serialization_test.cpp:21: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:567: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ Can someone explain to me WTF is going on? That error makes absolutely no sense at all to me, and I'm at my wits end! Thanks, -- Dominick

Serialization newbie needs help
by Hector C. 18 Aug '07

Hi all, I just cannot understand why the following code fails to compile. I have read the help files, did my Google, stared at it for hours, etc. But I cannot make sense. It compiles to the following message. Any ideas will be appreciated, --Hector C. ----MESSAGE---- // if your program traps here, it indicates taht your doing one of the following: // a) serializing an object of a type marked "track_never" through a pointer. // b) saving an non-const object of a type not markd "track_never) // Either of these conditions may be an indicator of an error usage of the // serialization library and should be double checked. See documentation on // object tracking. --END MESSAGE-- ----CODE---- #include <iomanip> #include <iostream> #include <fstream> #include <string> #include <boost/archive/text_iarchive.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/serialization/base_object.hpp> #include <boost/serialization/utility.hpp> #include <boost/serialization/list.hpp> using namespace std; class A { public: string m; A(){}; private: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & m; } }; int main(int argc, char * argv[]) { A a; { ofstream off("test.txt"); boost::archive::text_oarchive oa(off); //Uncommenting any of the following lines //produces compilation errors //oa << a; //oa << (const A) a; } return 0; } ---END CODE--- ---------------------------------- ____________________________________________________________________________________ Building a website is a piece of cake.

where is Accumulators library?
by Frank Birbacher 17 Aug '07

17 Aug '07

Hi! The Accumulators library from Eric Niebler has been accepted for boost on February 19th. Now I cannot find evidence anywhere in boost: - neither the release has it - nor the CVS - nor the sandbox SVN I want to use this library. How? Frank

[boost-users] boost assignment problem on non primitive type.
by chun ping wang 17 Aug '07

17 Aug '07

Question 1. std::vector<Roles> vr; the constructor for Roles: enum Role { .....}; explicit Roles (const std::string& usr, const Role& r); How would I use boost::assign::list_of to assign a vector of Roles instead of doing regular vector push_back. Question 2. Related. I have a Hash map i.e. boost::unordered_map<std::string, compositionType> and i want to use boost::map_list_of how would i do that. Question 3. trying to use operator += in boost::assignment i get error specifying unknown types. typedef boost::function<std::vector<int>(std::vector<int>)> sortfunc; std::vector<sortfunc> function_list; // quicksort random function_list += (&quicksort<QSTYPE(RANDOM), int, std::vector>) // quicksort median (&quicksort<QSTYPE(MEDIAN), int, std::vector>) // error here. // quicksort mediantriple (&quicksort<QSTYPE(MEDIANTRIPLE), int, std::vector>) // merge sort (&mergesort<int, std::vector>) // heap sort (&heapsort<int, std::vector>) // selection sort (&selection_sort<int, std::vector>) // standard sort (&standard_sort<int, std::vector>); Thanks for any help in advanced.

How to compile Boost for use with MinGW in Linux
by Ravi kumar Singh 17 Aug '07

17 Aug '07

I want to use Boost libraries with my MinGW compiler installed in my Linux Desktop, since I want to cross-compile a few programs for ms-windows. Though I have Boost installed in my system for native compilation, but I am unable to compile it for MinGW. Recently I have tried to compile Boost for MinGW, first by executing the following commands :- export CC=i586-mingw32msvc-gcc export CXX=i586-mingw32msvc-c++ export LD=i586-mingw32msvc-ld export AR=i586-mingw32msvc-ar export AS=i586-mingw32msvc-as export NM=i586-mingw32msvc-nm export STRIP=i586-mingw32msvc-strip export RANLIB=i586-mingw32msvc-ranlib export DLLTOOL=i586-mingw32msvc-dlltool export OBJDUMP=i586-mingw32msvc-objdump export RESCOMP=i586-mingw32msvc-windres and then :- ./configure make but it still produced native libraries..... Please tell me how to achieve that, or if you have any link where I can find proper instructions to do so. Thanks --------------------------------- Why delete messages?
