[regex] undefined references to boost::reg_expression
by Ken Klose 15 Jun '07

15 Jun '07

I've been able to build this program without problem on one RHEL4 machine with boost 1.33.1. But on another machine it gives a ton of errors (see below). Any thoughts would be greatly appreciated. Thanks, Ken #include <iostream> #include <string> #include "boost/regex.hpp" using namespace boost; using namespace std; int main() { string _stream("1000_===_1181763561847_===_false"); boost::sregex_token_iterator _tokens, _end; _tokens = sregex_token_iterator(_stream.begin(), _stream.end(), regex("_===_", boost::regex::literal), -1); while(_tokens != _end) { cout << *_tokens++ << endl; } } make -f sample.mak all make[1]: Entering directory `/users/sd/jbfsa/bolanosr/dci_test/DciSample' g++ -Wall -g -D__OS_LINUX__ -pthread -I../DciApi/include -I../DciApi -I../boost_release/boost

[Function][bind]Using function to store arbitrary class and arbitrary function
by Hughes, James 15 Jun '07

15 Jun '07

Hello all, I have a quick question that I hope some of the experts on Function and Bind can answer. I'll give a quick précis of what I would like to do. We have an event system in our code. I would like to set this up so that any particular event can be 'attached' to arbitrary classes and functions in those classes. For example, a "Print" Event may need to call an arbitrary function in an arbitrary class (or a number of these). Therefore the event server needs to have a list of all these class/function pairs for each event type. I am pretty sure I can achieve that with a combination of boost::function and boost::bind. I see how I can use function if I know what the class type is..I would need to store the function and a this pointer in to the event server, but the this pointer would need to be to a specific type - that specified in the boost::function defn. Is there any way to make the this pointer of an arbitrary type such that the function call can be made to any arbitrary function in any arbitrary class? Sorry, I don't have a code snippet to help explain - that's what I'm trying to figure out!! There may well be better ways of doing what we need - those thoughts also gratefully received (nb.

multi_index_container and hash_key lookup with boost boost-1.33.1
by Andrej van der Zee 15 Jun '07

15 Jun '07

Hi, I have a problem with a hash-index to a member of type std::vector<std::strings>. With boost 1.34 it compiles and runs find, but it fails to compile with 1.33! Unfortunately I do not have the luxury to change boost-version. Is there any way around this? I defined my multi_index_container like this: typedef std::vector<std::string> keys_type; struct entry_type { keys_type keys; bool operator<(const entry_type& e) const { ... } }; typedef boost::multi_index::multi_index_container< entry_type, mi::indexed_by< mi::hashed_unique< mi::tag<hash_index_tag>, mi::member<entry_type, keys_type, &entry_type::keys> >, mi::ordered_non_unique< mi::tag<pred_index_tag>, mi::identity<entry_type> > > > mi_entries_type; And get the following compile-error (see the bottom): /usr/bin/g++ -m64 -pipe -Wall -fPIC -O3 -DNDEBUG -I../framework

[date time] performant?
by John McMahon 14 Jun '07

14 Jun '07

Hi, I've been browsing the online documentation for the date time library, which is a model of good documentation (unlike boost::test, for example) and it looks pretty well designed. I wanted to know if there have been any discussions or benchmarks of how efficient it is? Do people have any general comments on this? Some background: I've been looking at quantlib (www.quantlib.org) - a c++ library which performs financial valuation calculations, and whilst they use boost, they have chosen to write their own Date and Calendar classes. Dates, holiday calendars, period calculations, etc, are commonly used in finanial calculations and a performant library generally would add great value. thanks in advance, John McMahon

Problem with boost serialization: shared_ptr
by Michel Pineau 14 Jun '07

Hello, I'm trying to serialize many boost::shared_ptr to the same object but through different base classes. When I look at the boost::shared_ptr for the base classes they are not properly set. I created a simple example that show my problem. The test program output is: Running 1 test case...

Re: [Boost-users] Getting the argument types from a function type
by Benjamin Winkler 14 Jun '07

14 Jun '07

Hello Kirit, to solve your specific problem, you could just do without Boost.function and also use templates for operator(): template <class C, typename F> class with_binder { C& m_this; F m_fn; public: with_binder(C& ref, F fn) : m_this(ref), m_fn(fn) { } // one parameter template <typename T1> const with_binder<C,F>& operator()(T1& v1) const { (m_this.*m_fn)(v1); return *this; } template <typename T1> const with_binder<C,F>& operator()(const T1& v1) const { (m_this.*m_fn)(v1); return *this; } // two parameters template <typename T1, typename T2> const with_binder<C,F>& operator()(T1& v1, T2& v2) const { (m_this.*m_fn)(v1, v2); return *this; } template <typename T1, typename T2> const with_binder<C,F>& operator()(const T1& v1, const T2& v2) const { (m_this.*m_fn)(v1, v2); return *this; } // ... and so on ... }; template <class C, typename F> with_binder<C,F> with(C& ref, F fn) { return with_binder<C,F>(ref,fn); } Regards, Benjamin >I've been playing around with a few functional programming idioms in C++ >using Boost.function and Boost.lambda and was wondering if it was >possible to fetch out the argument type (i.e. int) from a type like this: > >void (*somefunc)( int ) > >It looks to me like boost::function<> might be doing something along >these lines. > >I've been working on a version of 'with' for use in initialising lists >etc. At the moment you need to do this: > > std::list< int > list1; > list1.push_back( 3 ); > list1.push_back( 1 ); > list1.push_back( 4 ); > >But using 'with' you can do this: > > with( list2, &std::list< int >::push_back )( 3 )( 1 )( 4 )( 1 )( 5 ); > >The implementation I have right now is fairly simple: > >template< typename F > >struct with_binder { > with_binder( F f ) > : m_f( f ) { > } > const with_binder &operator()( int i ) const { > m_f( i ); > return *this; > } >private: > F m_f; >}; >template< typename O, typename F > inline >with_binder< boost::function< void ( int ) > > with( O &o, F f ) { > return with_binder< boost::function< void ( int ) > >( >boost::lambda::bind( f, &o, boost::lambda::_1 ) ); >} > >But the 'int' argument type is hard coded.

optimizing use of dynamic_bitset
by Dave Steffen 14 Jun '07

14 Jun '07

Hi Folks, Having gotten a big chunk of code to work, I'm now spending a few days making it fast. So far, I've removed enough overhead to drop our runtime by a factor of 4, and a big part of that was replacing some other data structures with dynamic_bitset. Profiling data now indicates that one of the more expensive operations is spending most of its time calling dynamic_bitset<>::test a bajillion times. My question is this: is dynamic_bitset::test generally thought to be the fastest way to access a specific bit in a dynamic_bitset? Are there other ways to determine if bit n is set? (I assume that anything using dynamic_bitset::operator[] will be slower, since it has to set up a proxy, but have not tested this.) Any thoughts are appreciated.

Boost 1.34 and VC++ 64

Hi boost users, I am trying to install Boost 1.34 in a Vista x64 (Core-duo) & VC++ 2005. I could compile the x32 version without any problems. But, when trying to compile the x64 version I have the popup message "Windows cannot open this file : execution_monitor.obj.rsp" The command I used was: bjam --build-dir=C:\tmp\build-boost --toolset=msvc address-model=64 stage Any help would be highly appreciate, Yutaka Leon.
