Boost 1.35 build problem
by Johan Råde 20 Feb '08

20 Feb '08

I downloaded Boost 1.35 Head from SVN. I built it with the command: bjam --toolset=msvc-7.1 --NO_ZLIB=0 -sZLIB_SOURCE=C:/Qt/3.3.8/src/3rdparty/zlib install Then I tried to rebuild our app. I got the linking error: LINK : fatal error LNK1104: cannot open file 'libboost_serialization-vc71-mt-1_35.lib' The folder C:/Boost/lib does not contain the file libboost_serialization-vc71-mt-1_35.lib. It seems it was not built. The folder contains boost_serialization-vc71-mt-1_35.dll boost_serialization-vc71-mt-1_35.lib boost_serialization-vc71-mt.lib but no other xxx_serialization_yyy libs. The same happens with the other Boost libs, not just with the serialization lib. Does anyone have any idea what the problem might be, or what additional information I should provide? Thank you, Johan Råde

I submitted this question to the boost-build list, which is where I should have sent it originally.

Why not overloading && and || in bind?
by Jean-Pierre Bergamin 20 Feb '08

20 Feb '08

Hello everyone Is there a reason why boost::bind does not overload the logical operators || and &&? They definitively would come in more handy to build up complicated logical expressions than using the std::logical_and and std::logical_or function objects. Adding... BOOST_BIND_OPERATOR( ||, logical_or ) BOOST_BIND_OPERATOR( &&, logical_and ) ...to the operator definitions in bind.hpp works as expected with the code below (tested with MSVC 2008). So - why not? :-) Regards James ////////////////////////////////////////////////// // Code example: ////////////////////////////////////////////////// struct employee { employee(int id, const string &name) : id(id), name(name) {} int id; string name; }; ostream &operator<<(ostream &o, const employee &e) { o << e.id << " - " << e.name << endl; return o; } typedef vector<employee> emp_container; emp_container staff; staff.reserve(4); staff.push_back(employee(1, "John")); staff.push_back(employee(2, "Paula")); staff.push_back(employee(3, "Sara")); staff.push_back(employee(4, "Geroge")); emp_container::const_iterator e = find_if(staff.begin(), staff.end(), bind(&employee::name, _1) == "Paula" || bind(&employee::name, _1) == "John" || bind(&employee::id, _1) >= 4 ); if (e != staff.end()) { cout << "Found: " << *e << endl; }

compile problem using multi_index_container
by Dwight Kelly 20 Feb '08

20 Feb '08

Hello, I've encountered a problem compiling code that uses boost multi_index_container. I'm using both Microsoft Visual Studio 2005 and Apple's gcc 4.0.1. Visual Studio was very picky about how I used namespaces. I finally got it working with the code below. The key to success was the 'using namespace boost::multi_index' line. If I attempted to prefix the members directly, eg. typedef typename boost::multi_index::nth_index_const_iterator<0>::type left_const_iterator; or namespace mi=boost::multi_index; typedef typename mi::nth_index_const_iterator<0>::type left_const_iterator; it would fail to compile. However, when I attempt to compile the same code on Mac OS X using gcc 4.0.1 I get the following errors. Does anyone know why? src.cpp:98:error: wrong number of template arguments (1, should be 2) /boost/boost/multi_index_container_fwd.hpp:46: error: provided for 'template<class MultiIndexContainer, int N> struct boost::multi_index::nth_index_const_iterator' src.cpp:98: error: expected ';' before 'left_const_iterator' src.cpp:99: error: wrong number of template arguments (1, should be 2) /boost/boost/multi_index_container_fwd.hpp:46: error: provided for 'template<class MultiIndexContainer, int N> struct boost::multi_index::nth_index_const_iterator' src.cpp:99: error: expected ';' before 'right_const_iterator' -----code---- using namespace boost::multi_index; 88 template<class A, class B=String> 89 class SimpleBiMap : public multi_index_container< 90 pair<A,B>, 91 indexed_by< 92 ordered_unique<member<pair<A,B>, A, &pair<A,B>::first> >, 93 ordered_unique<member<pair<A,B>, B, &pair<A,B>::second> > 94 > > 95 { 96 public: 97 typedef pair<A,B> mytype; 98 typedef typename nth_index_const_iterator<0>::type left_const_iterator; 99 typedef typename nth_index_const_iterator<1>::type right_const_iterator; 100 101 SimpleBiMap(const mytype init[], int N) { 102 for (int i=0; i<N; i++) { 103 insert(init[i]); 104 } 105 } 106 107 left_const_iterator find(const A &key) const { return get<0>().find(key); } 108 right_const_iterator find(const B &key) const { return get<1>().find(key); } 109 110 left_const_iterator left_end() const { return get<0>().end(); } 111 right_const_iterator right_end() const { return get<1>().end(); } 112 113 const B &operator[](const A &key) const { return get<0>().find(key)->second; } 114 const A &operator[](const B &key) const { return get<1>().find(key)->first; } 115 }; ---code--- Thank you, Dwight Kelly Apago, Inc.

Serialization problem
by christophe loustaunau 20 Feb '08

20 Feb '08

Hello, I try to use serialization of boost. I have started with the exemple of bus stop in XML : http://www.boost.org/libs/serialization/example/demo_xml.cpp I have added to this example a map of 1000 bus_schedule. Then I save this map in a file. And I relaod this file in a new map. This works perfectly in XML, but if I try : binary_iarchive I got an boost::archive::archive_exception at memory location 0x00dfdb40.. I don't understand why It woks in XML and not in binary. I have attached to the mail the source file. If someone could help me It would be great ! Thanks. -- Christophe Loustaunau.

scope_lock problem
by Bernard Maassen 20 Feb '08

20 Feb '08

Hi all i'm porting a program written in visual studio 2005 to vs 2003, and came to a problem i can't fix. The idea is to have a lock a mutex while a object excists. The code is: template <class B> class BaseReadLockProxy { private: const B& base; typename B::MutexType::scoped_lock baseScoped_lock; public: BaseReadLockProxy(const B& b): base(b), baseScoped_lock( B::MutexType::scoped_lock(b.baseMutex)) { } typename const B::ContainerType& getItems() { return base.getItems(); } ~BaseReadLockProxy() { } }; Where B::MutexType: typedef boost::mutex MutexType; When compiling this gives: e:\stage2\2apl\2aplcore\BaseScopeLockedProxy.h(39) : error C2558: class 'boost::detail::thread::scoped_lock<Mutex>' : no copy constructor available or copy constructor is declared 'explicit' with [ Mutex=boost::mutex ] e:\stage2\2apl\2aplcore\BaseScopeLockedProxy.h(36) : while compiling class-template member function 'doubleapl::BaseReadLockProxy<B>::BaseReadLockProxy(const B &)' with [ B=doubleapl::PRRuleBase ] RuleOption.cpp(112) : see reference to class template instantiation 'doubleapl::BaseReadLockProxy<B>' being compiled with [ B=doubleapl::PRRuleBase ] I know it should work, because it compiles/runs when using visual studio 2005. Does anyone have an idea what could cause this problem? All ideas are welcome, cause i'm totally stuck

Hi! I cannot find in docs how to create named vales for producing output like shown in this example from docs: $bin/gcc/debug/multiple_sources --help Allows options: Generic options: -v [ --version ] : print version string --help : produce help message Configuration: --optimization n : optimization level -I [ --include-path ] path : include path The "--include-path" option shown above has "path" parameter, what I have is "arg".

Hi Everyone...I am now asking about a package that I do not know at all. We are running Suse enterprise linux 9 and I am trying to install a plugin for nagios but I am getting the message that libboost.thread could not be found. I tried to look for the package on the system but could not find. I then tried looking for it on the net but no luck in finding the install packages.

Pairing ptr_containers with zip iterators
by Charles Brockman 20 Feb '08

20 Feb '08

Is it possible to use Boost ptr_containers with Boost zip iterators? I switched from std::map to boost::ptr_map in my application and received numerous complaints from the Microsoft Visual Studio C++ 2008 compiler. As a small test I compiled \trunk\libs\iterator\test\zip_iterator_test.cpp from Boost SVN which worked fine. Then I added the necessary ptr_container include file, disabled a lot of extra tests and changed the definition of the two vectors from std::vector<double> vect1(3); to boost::ptr_vector<double> vect1(3); and std::vector<double> vect2(3); to boost::ptr_vector<double> vect2(3); Here is the error reported: c:\boost svn\trunk\boost\tuple\detail\tuple_basic.hpp(373) : error C2664: 'std::_Vector_const_iterator<_Ty,_Alloc>::_Vector_const_iterator(const std::_Vector_const_iterator<_Ty,_Alloc> &)' : cannot convert parameter 1 from 'const boost::void_ptr_iterator<VoidIter,T>' to 'const std::_Vector_const_iterator<_Ty,_Alloc> &' with [ _Ty=double, _Alloc=std::allocator<double> ] and [ VoidIter=std::_Vector_iterator<void *,std::allocator<void *>>, T=double ] and [ _Ty=double, _Alloc=std::allocator<double> ] Reason: cannot convert from 'const boost::void_ptr_iterator<VoidIter,T>' to 'const std::_Vector_const_iterator<_Ty,_Alloc>' with [ VoidIter=std::_Vector_iterator<void *,std::allocator<void *>>, T=double ] and [ _Ty=double, _Alloc=std::allocator<double> ] No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called c:\boost svn\trunk\boost\tuple\detail\tuple_basic.hpp(626) : see reference to function template instantiation 'boost::tuples::cons<HT,TT>::cons<T0,boost::tuples::cons<T0,boost::tuples::detail::map_tuple_to_cons<boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type>::type>>(const boost::tuples::cons<T0,boost::tuples::cons<T0,boost::tuples::detail::map_tuple_to_cons<boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type>::type>> &)' being compiled with [HT=std::_Vector_const_iterator<double,std::allocator<double>>,TT=boost::tuples::cons<std::_Vector_const_iterator<double,std::allocator<double>>,boost::tuples::detail::map_tuple_to_cons<boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type>::type>, T0=boost::void_ptr_iterator<std::_Vector_iterator<void *,std::allocator<void *>>,double> ] c:\documents and settings\chuck\my documents\visual studio 2005\projects\zip ptr container test\zip_ptr_container_test.cpp(267) : see reference to function template instantiation 'boost::tuples::tuple<T0,T1>::tuple<boost::void_ptr_iterator<VoidIter,T>,boost::tuples::cons<HT,TT>>(const boost::tuples::cons<HT,boost::tuples::cons<HT,TT>> &)' being compiled with [ T0=std::_Vector_const_iterator<double,std::allocator<double>>, T1=std::_Vector_const_iterator<double,std::allocator<double>>, VoidIter=std::_Vector_iterator<void *,std::allocator<void *>>, T=double, HT=boost::void_ptr_iterator<std::_Vector_iterator<void *,std::allocator<void *>>,double>, TT=boost::tuples::detail::map_tuple_to_cons<boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type,boost::tuples::null_type>::type ] The line 267 (line 295 in the original version) referred to is: boost::zip_iterator< boost::tuples::tuple< std::vector<double>::const_iterator, std::vector<double>::const_iterator > > zip_it_begin( boost::make_tuple( vect1.begin(), vect2.begin() ) ); Is it the void pointer in the ptr_vector which causes the problem?
