Re: [Boost-users] Boost Static Linking Woes
by Brian Dawn 13 Nov '08

13 Nov '08

Hello everyone, I am sorry, I did not explain my situation as well as I should have. I have a complete build of boost installed so I had assumed it created static libraries alongside dynamic ones. When I received the "Mixing a dll boost library with a static runtime is a really bad idea..." message I had assumed autolink was to blame because I had assumed it would recognize the static install and thus search for the static libraries. When I disabled autolink I directly linked to "libboost_whatever.lib" as those are the static libraries correct? However that's when I received the heap corruption. As for the macros... I checked my user & config files, and BOOST_ALL_DYN_LINK was commented out. >> That suggests a build problem somewhere: do you still have BOOST_ALL_DYN_LIB defined or something? By still, do you mean that it is defined by default? Because I had never undefined it. Does boost complete build both static and dynamic libraries? Because maybe that is my problem. I appreciate everyone's help. Thanks, -Brian.

Re: [Boost-users] Bind and overloaded operators in Visual Studio 2008

> The bug you're seeing is in Dinkumware's bind, not boost's. > Try using boost::bind explicitly and I suspect it will work fine. Thanks for the quick answer. I replaced it with #include <boost/bind.hpp> std::find_if(v.begin(), v.end(), boost::bind( &Foo::first_, _1 ) == test ); which works. I did, however, configure Visual Studio to prefer Boost's TR1 implementation by adding the following include directories before the Microsoft includes (Tools->Options->Projects and Solutions->VC++ Directories->Include files): - boost-root/boost/tr1/tr1 - boost-root This worked as expected with VS2005 but with VS2008 the Microsoft/Dinkumware includes are apparently still preferred.

Re: [Boost-users] I have a crash when I included serialization in my Mixed C++ project

Thanks it worked. Looks like Microsoft has not fixed it in VS 2008 also. I went to project properties > linker settings > advanced and changed entry point from "main" to "?mainCRTStartupStrArray@@$$FYMHP$01AP$AAVString@System@@@Z" I appreciate your help very much. You have saved me a lot of time.

us_dst_rules::dst_start_offset -- version change issue?
by Joseph A. Marks 12 Nov '08

12 Nov '08

We recently upgraded to Boost 1_36_0. The following line used to compile correctly: boost::posix_time::time_duration td = us_dst_rules::dst_start_offset(); However, now I get the following error: error C2039: 'dst_start_offset' : is not a member of 'boost::date_time::us_dst_rules<date_type_,time_duration_type_>' Does anyone have any insight on how to correct this issue?

[function] Automatic boost::ref for functors?
by Robert Dailey 12 Nov '08

12 Nov '08

Hi, I noticed in the Boost.Function documentation here that it explains how to pass a reference to a function object into a boost::function. Is there a way to make boost::function automatically take the reference of any function object it is given? For example: boost::function<void (int)> f; f = MyFunctionObject(); // This is an implicit: f = boost::cref( MyFunctionObject() ); Help is appreciated!

Bind and overloaded operators in Visual Studio 2008
by Benjamin Swerts 12 Nov '08

12 Nov '08

Hello everyone, This is my first post to this list so apologies in advance for all the rules I will be breaking. I have a problem using overloaded operators in Visual Studio 2008 SP1 (no feature pack installed) with Boost version 1.36.0. The following code works perfectly in Visual Studio 2005: ////////// #include <algorithm> #include <functional> #include <vector> struct Foo { Foo(unsigned int first, unsigned int second) : first_(first), second_(second){}; unsigned int first_; unsigned int second_; }; int main(int, char*) { std::vector<Foo> v(10, Foo(1, 2)); const unsigned int test = 1; std::find_if(v.begin(), v.end(), std::tr1::bind( std::equal_to<unsigned int>(), std::tr1::bind(&Foo::first_, std::tr1::placeholders::_1), test)); std::find_if(v.begin(), v.end(), std::tr1::bind( &Foo::first_, std::tr1::placeholders::_1 ) == test ); return 0; } ////////// The 2 find_if calls have the exact same behaviour. If I compile this with 2008, I get the following errors for the second find_if call: .\main.cpp(19) : error C2784: 'bool std::tr1::operator ==(std::tr1::_Unutterable,const std::tr1::function<_Fty> &)' : could not deduce template argument for 'const std::tr1::function<_Fty> &' from 'const unsigned int' C:\Program Files\Microsoft Visual Studio 9.0\VC\include\../include/functional(1100) : see declaration of 'std::tr1::operator ==' .\main.cpp(19) : error C2784: 'bool std::tr1::operator ==(const std::tr1::function<_Fty> &,std::tr1::_Unutterable)' : could not deduce template argument for 'const std::tr1::function<_Fty> &' from 'std::tr1::_Bind<_Ret,_BindN>' with [ _Ret=std::tr1::_Notforced, _BindN=std::tr1::_Bind1,std::tr1::_Ph<1>> ] C:\Program Files\Microsoft Visual Studio 9.0\VC\include\../include/functional(1094) : see declaration of 'std::tr1::operator ==' .\main.cpp(19) : error C2784: 'bool std::tr1::operator ==(const std::tr1::shared_ptr<_Ty> &,const std::tr1::shared_ptr<_Ty2> &)' : could not deduce template argument for 'const std::tr1::shared_ptr<_Ty> &' from 'std::tr1::_Bind<_Ret,_BindN>' with [ _Ret=std::tr1::_Notforced, _BindN=std::tr1::_Bind1,std::tr1::_Ph<1>> ] C:\Program Files\Microsoft Visual Studio 9.0\VC\include\../include/memory(1598) : see declaration of 'std::tr1::operator ==' .\main.cpp(19) : error C2676: binary '==' : 'std::tr1::_Bind<_Ret,_BindN>' does not define this operator or a conversion to a type acceptable to the predefined operator with [ _Ret=std::tr1::_Notforced, _BindN=std::tr1::_Bind1,std::tr1::_Ph<1>> ] I have honestly no idea what I should do to fix this. Mailing list and google searches turned up nothing so any help would be much appreciated.

Multidimensional distributions in the math toolkit?
by jesseperla＠gmail.com 12 Nov '08

12 Nov '08

Hi, I realize that it isn't in the released version, but has any thinking or progress been made on multidimensional distributions extending the math toolkit distributions? I would love to have a bi-normal, bi-lognormal, and a discrete 2-dim Markov distribution? Thanks, Jesse

boost timer with sleep
by Andre Paim Lemos 12 Nov '08

12 Nov '08

The following code: #include <iostream> #include <boost/timer.hpp> #include <unistd.h> int main() { boost::timer t; sleep(1); std::cout << t.elapsed() << std::endl; t.restart(); sleep(3); std::cout << t.elapsed() << std::endl; return(0); } Returns (compiled with gcc 4.2.4 on Ubuntu Linux 8.04 using boost 1.36): andre@andre-desktop:~/test$ ./timer_test 0 0 Is this result expected? Why? There is another timer implementation that works with sleep? []'s Andre Paim Lemos

I have a crash when I included serialization in my Mixed C++ project
by Raj Prasan 12 Nov '08

12 Nov '08

I had a project using both native and CLR code C++.Net. I added serialization to it. Its just crashing. I checked RTTI IS enabled.. I had this problem earlier. I had split the serialization function to both .h and .cpp files. Then it disappered when I wrote it in the class declaration in the .h file. But after I did the same to all the classes (almost 20) that needed serialization. It compiles fine, but crashes even before starting..

Hello Andrew, thank you for your suggestions. Unfortunately I still have compile problems. I tried both ways, indexing by bundled properties and by using an external map. Inside the call of breadth_first_search(...) both ways end with the same compiler error (partially in german) : boost_1_35_0\boost\graph\visitors.hpp(160): error C2664: 'void put<std::allocator<_Ty>::value_type,Vertex>(T * ,ptrdiff_t,const V & )': Konvertierung des Parameters 2 von 'boost::adjacency_list_traits<OutEdgeListS,VertexListS,DirectedS>::vertex_descriptor ' in 'ptrdiff_t' nicht möglich with [ _Ty=boost::detail::adj_list_gen<boost::adjacency_list<boost::listS,boost::listS,boost::bidirectionalS,boost::property<boost::vertex_distance_t,unsigned int,de::audi::scenetree::VertexContainer>,GeoTrafo::cPose>,boost::listS,boost::listS,boost::bidirectionalS,boost::detail::retag_property_list<boost::vertex_bundle_t,boost::property<boost::vertex_distance_t,unsigned int,de::audi::scenetree::VertexContainer>>::type,boost::detail::retag_property_list<boost::edge_bundle_t,GeoTrafo::cPose>::type,boost::no_property,boost::listS>::config::vertex_ptr , Vertex=boost::adjacency_list_traits<boost::listS,boost::listS,boost::bidirectionalS>::vertex_descriptor, T=std::allocator<boost::detail::adj_list_gen<boost::adjacency_list<boost::listS,boost::listS,boost::bidirectionalS,boost::property<boost::vertex_distance_t,unsigned int,de::audi::scenetree::VertexContainer>,GeoTrafo::cPose>,boost::listS,boost::listS,boost::bidirectionalS,boost::detail::retag_property_list<boost::vertex_bundle_t,boost::property<boost::vertex_distance_t,unsigned int,de::audi::scenetree::VertexContainer>>::type,boost::detail::retag_property_list<boost::edge_bundle_t,GeoTrafo::cPose>::type,boost::no_property,boost::listS>::config::vertex_ptr >::value_type, V=boost::adjacency_list_traits<boost::listS,boost::listS,boost::bidirectionalS>::vertex_descriptor ] and [ OutEdgeListS=boost::listS, VertexListS=boost::listS, DirectedS=boost::bidirectionalS ] Diese Konvertierung erfordert einen reinterpret_cast-Operator oder eine Typumwandlung im C- oder Funktionsformat For example index and property map definition with bundled property: typedef unsigned int VertexID; class SCENETREELIB_API VertexContainer { public: VertexID m_idVertex; } typedef property_map<BGLGraph, VertexID VertexContainer::*>::type IndexMap; // Build the property map IndexMap im = get(&VertexContainer::m_idVertex, graphIn); std::vector<BGLVertexDescriptor> p(num_vertices(graphIn)); Any further suggestions? greetz Manuel -- Ist Ihr Browser Vista-kompatibel?
