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

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... In function ABC In function A In function B In function C In function ABC In function A In function A In function A I'm using boost 1.33.1 on Linux with gcc 3.4.5 (Red Hat 3.4.5-2).

Re: [Boost-users] Getting the argument types from a function type
by Benjamin Winkler 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. Thanks! -- Dave Steffen, Ph.D. Disobey this command! Software Engineer IV - Douglas Hofstadter Numerica Corporation dg@steffen a@t numerica d@ot us (remove @'s to email me)

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.

derivative work
by Ruediger Berlich 14 Jun '07

14 Jun '07

Hi there, just a short question about the meaning of "derivative work" in the Boost software license (and the associated requirement to list the Copyright and license terms in such work). My understanding of the term "derivative work" is that it applies to modifications of the original code only, not to software _using_ the code. I.e., if I were to modify the code in shared_ptr.hpp, then of course I would have to include the original Copyright notices and license terms. Whereas, if I use shared_ptr in my software, I do not need to list the original Copyright notices and license terms. Plus, the Copyright of my own cose is solely with me. Is this interpretation correct ? Best Regards and thanks for your help, Ruediger Berlich

Getting the argument types from a function type
by Kirit Sælensminde 14 Jun '07

14 Jun '07

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. I could have it as the first template parameter to 'with' and simply require that it is given when using 'with', but it would neater if it could be derived from the type 'F' in 'with'. Clearly to be more generally useful it also needs to be extended for multiple parameters. K

Hi, I am trying to build boost on a debian system using bash shell. I am getting erros: /bin/sh: line 1: chdir: command not found Is this a common problem? Should i just alias chdir to cd? Thanks, Ivan --------------------- Ivan Novick http://www.0x4849.net

graph library : isomorphism.hpp vertex invariant parameter
by Patrick A. La Fratta 14 Jun '07

14 Jun '07

Setting the "vertex_invariant" parameter to the isomorphism function does not seem to have any affect on the behavior of the function. In isomorphism.hpp, it appears that the function "isomorphism_impl" is supposed to read the parameter at the return statement: return isomorphism(G1, G2, f, choose_param(get_param(params, vertex_invariant1_t()), invariant1), choose_param(get_param(params, vertex_invariant2_t()), invariant2), choose_param(get_param(params, vertex_max_invariant_t()), ( invariant2.max )()), index_map1, index_map2 ); If "vertex_invariant1_t()" and "vertex_invariant2_t()" are both changed to "vertex_invariant_t()", the setting of the parameter then seems to have an affect. Has anyone been able to successfully set the vertex_invariant parameter using the named parameter version of the isomorphism function? I have had to resort to calling one of the internal isomorphism functions to set this parameter. any help is appreciated, Patrick

some libraries missing
by Fulvio Esposito 13 Jun '07

13 Jun '07

Hi all boost users, recently I downloaded source package for version 1.34 from sf.net, but i discovered some library that was accepted were missing (like asio, gil and some others). I think at least they should be in CVS but i've never worked with a source control system. How can I obtain a full distribution from CVS? I'm working on Microsoft Windows XP/Visual C++ Express 2005! Thank you all guys, Fulvio Esposito
