win32.hpp has a using std::max, min
by Charles Schwartz 08 Sep '03

08 Sep '03

win32.hpp has using std::min and using std::max directives. (win32.hpp in fact overrides these functions). These directives hinder use of the max function elsewhere in a client program, for example, by #included c libraries, which are expecting to use the global (non overridden) max function. Indeed, Sutter's More Exceptional C++ #40 (p. 236) asserts that using directives/declerations should never appear in any headers (certainly not at file scope!). Will this be removed in future releases?

Building Boost with Intel compiler 7.0 and STLPort on windows
by Andre du Toit 08 Sep '03

08 Sep '03

Hello. Does anyone know whether it is currently possible to use Boost with the Intel Compiler v7.0 and the latest STLport, in windows? It seems I still have to hack files in date_time/posix_time (specifically time_formatters.hpp), to reduce my compile errors. Like defining BOOST_MSVC and then undeffing it, before line 43 of this file is processed. Otherwise I get ambigious operator definitions. Also, is it possible to actually build the date_time library with the Intel compiler and STLport at the same time? Why is there a msvc-stlport toolset but no intel-stlport toolset? O; another thing. Has anyone perhaps built boost in MSYS before? If MSVC + Intel setup is giving me too much hassle, I am going to try and build boost in MSYS. Greetings, Andre

lambda and smart pointers
by Rodolfo Lima 08 Sep '03

08 Sep '03

What's the proper way to use lambda with smart pointers? I'm trying to compile the following: class Dados { public: Dados(int _a) : a(_a) {}; int Pega() const { return a; } private: int a; }; int main() { shared_ptr<Dados> pDados(new Dados(5)); cout << (bind(&Dados::Pega, _1)(pDados)==5) << endl; return 0; } I've already tried with *_1 with no success. In this case, the compiler (VC7.1) returns "error C2039: 'iterator_category' : is not a member of 'boost::shared_ptr<T>'". Any hope? Thanks, rod

Compile errors boost 1.30.2
by Andre du Toit 08 Sep '03

08 Sep '03

Hi. I get the following error when compiling the latest version of boost, using Intel compiler 7.0 in visual c++: ..\..\..\boost\boost/type_traits/is_integral.hpp(39): error: class "boost::is_integral<unsigned short>" has already been defined BOOST_TT_AUX_BOOL_TRAIT_CV_SPEC1(is_integral,wchar_t,true) Now the offending line sits between a "#ifndef BOOST_NO_INTRINSIC_WCHAR_T". The simple fix of defining BOOST_NO_INTRINSIC_WCHAR_T solves this problem, but causes other problems in other locations. All I want is to compile and link against boost::date_time library, using my compiler setup. Thats all. Any suggestions? Greetings, Andre

is this what you had in mind?? I've considered this from time to time (first time I've formalized it tho) especially thinking of alternatives to the 3 delimiter arguments (substitute one?

[BGL] adjacency property iterator
by sashan 05 Sep '03

05 Sep '03

Hi Is there an adjancency iterator for property types. You can get an iterator for property types like this: typedef graph_property_iter_range<GraphType, vertex_name_t>::iterator VNameIterator; .... tie(It, ItEnd) = get_property_iter_range(m_Graph, vertex_name); I'd like to know if there is something similar for adjacency iterators. I posted this question a few days ago but got no response so I guess that the answer is no but I want to make sure. Thanks -- sashan http://www.cs.auckland.ac.nz/~sgov008/

using boost::mem_fn result as a parameter?
by Mark Sizer 04 Sep '03

04 Sep '03

I'm new to boost::bind and boost::mem_fn. I've read the documentation and I think I understand what they do, but I'm not sure how to use them to accomplish my task. I have a class that contains several vectors in a map. I want to put a "foreach" method on the class that will callback an arbitrary member function, of an arbitrary class, for each item in the vector. I'm stuck on the signature of that method. A quick sketch of the structure: class VectorContent { public: void dosomething(); // there are bunches more, which is why I don't // want a foreach for every possible choice. }; class VectorHolder { std::map<std::string, std::vector<VectorContent> >; std::vector<VectorContent>& rvectGet(const std::string& rksName); public: void foreach( const std::string& rksName, <WHAT?> ); }; // the callback Caller::Bar( VectorContent& vc ) { vc.dosomething(); } I see two options for the caller: // option 1 Caller::Foo1() { VectorHolder callee; // in this case, foreach uses boost::mem_fn(), not me callee.foreach( "VectorName", &this::Bar ); } // option 2 Caller::Foo2(); { VectorHolder callee; callee.foreach( "VectorName", boost::mem_fn(&this::Bar) ); } In the case of option 1, all callers must share a common base class, which they do NOT, so that the signature of VectorHolder::foreach can be: typedef void (BaseClass::* MyCallBack)(VectorContent&); Leading to: void VectorHolder::foreach( const std::string& rsName, MyCallBack callback ) { std::vector<VectorContent>& rvect = rvectGet( rsName ); std::for_each( rvect.begin(), rvect.end(), boost::mem_fn(callback) ); } In the case of option 2, I have no idea what the signature should be. But the resulting method would be: void VectorHolder::foreach( std::string& rsName, WHAT? callback ) { std::vector<VectorContent>& rvect = rvectGet( rsName ); std::for_each( rvect.begin(), rvect.end(), callback ); } Grateful for any help, - Mark P.S. If there's an "option 3", I'm up for that, too.

ostream_iterator and std::copy - better solutions?
by Jeff Flinn 03 Sep '03

03 Sep '03

Before rolling my own, does boost have a facility to stream out an iterator range without the dangling delimiter at the end? For example std::ostream& operator<<( std::ostream& s, const MyClass& aC ) { const std::string lDelim( "," ); std::vector<int> lInts; lInts.push_back(1); lInts.push_back(2); lInts.push_back(3); std::ostream_iterator<int> lItr( s, lDelim.c_str() ); std::copy( lInts.begin(), lInts.end(), lItr ); } yields: 1,2,3, I'm thinking something like the following usage would be nice: s << range_streamer( lInts.begin(), lInts.end(), "{", "," "}" ); yielding: {1,2,3} Any thoughts? -- Jeff Flinn Applied Dynamics, International

boost lambda examples

Hi MSVC 7.1, Windows 2000 I'm trying to get to grips with the boost lambda library. I've managed to get the first example to work: #include <boost/lambda/lambda.hpp> #include <iostream> #include <cstdlib> #include <list> #include <algorithm> int main() { using namespace std; using namespace boost::lambda; list<int> v(10); for_each(v.begin(), v.end(), _1 = 12 ); return EXIT_SUCCESS; } but when I add the following line (also from the docs): for_each( v.begin(), v.end(), cout << *_1 << '\n' ); I get the following errors: error C2039: 'reference' : is not a member of 'std::iterator_traits<int>' error C2146: syntax error : missing ';' before identifier 'type' error C2501: 'boost::lambda::detail::contentsof_type<A>::type' : missing storage-class or type specifiers error C2039: 'type' : is not a member of 'boost::lambda::detail::contentsof_type<A>' error C2146: syntax error : missing ';' before identifier 'type' I've tried including some the other Lambda headers but this didn't improve the situation.

how to create fixtures in unit test framework
by Anders Moe 03 Sep '03

03 Sep '03

Hi all. The boost unit test framework seems to lack the xUnit buildUp/tearDown (whatever) methods meant to faciliate the creation of fixtures. Does that mean there is an alternative idiom to achieve the same effect ? Constructing new class-test-cases for each test seems a bit overkill. Regards, Anders.

Hello Boost Users, When i try to compile a class that use a vector with CodeWarrior for PS2 R3.03, i have this error message : Error : illegal use of incomplete struc/union/class 'Metrowerks::compile_assert<0>' (instantiating: 'std::vector<int, std::allocator<int>>') (instantiating: 'std::__vector_imp<int, std::allocator<int>, l>') vector line 729 ompile assert<bool(sizeof(T) == sizeof(typename Metrowerks::strore_as<T>;;type))> And just above the error line, in the vector file : // Error : illegal use of incomplete struct/union/class 'Metrowerks::compile_assert<0>' // This means that the store_as table in <msl_utility> is not set correctly. // sizeof(T) == sizeof(typename Metrowerks::store_as<T>::type must be true. The code compiles and works perfectly with VC6 sp5 on PC and XBOX. Thanks for any help.

[BGL] Adding one graph to another
by Tarjei Knapstad 02 Sep '03

02 Sep '03

I need to add/copy one graph into another, both completely connected, and then create an edge between one vertex in the original graph and a vertex in the one copied into it. The edge/vertex properties needs to be copied as well, and this needs to be fairly efficient. The new edge is straightforward, but is there any functionality for the copy/add operation? (Something like an "add_component" algorithm I guess...) To my understanding both the copy_graph and copy_component algorithms both replace all the content in the target graph. If not, what would be the most efficient way to solve this sort of problem? Cheers, -- Tarjei Knapstad

spirit list_p example
by Larry 02 Sep '03

02 Sep '03

From boost-1.30.2 I built the list_parser.cpp example using MSVC++7.1. In the CSV list I added ",,2" to the end of the line to be parsed. The program ran but the neither of the added elements were included in the output vector. Having used the tokenizer before I know it will generally gobble up adjacent delimiters without any output. You can get the empty token if you ask for the delimiters as well and then just discard the delimiters (sort of). But I was surprised that the 2 didn't make it to the output vector. I expected the empty list entry would not make the output vector. I tried adding ~anychar_p to the rule but that didn't help. If I change the input list to add ",\"\",2" I get "" and 2 in the output vector. Applications like spreadsheets do not put missing column values for numeric columns as "" items generally. Maybe I am missing something because it certainly isn't the behavior I would expect (either from the parser or the tokenizer).

adjancency propoerty iterator
by sashan 02 Sep '03

Hi Is there an adjancency iterator for property types. You can get an iterator for property types like this: typedef graph_property_iter_range<GraphType, vertex_name_t>::iterator VNameIterator; .... tie(It, ItEnd) = get_property_iter_range(m_Graph, vertex_name); I'd like to know if there is something similar for adjacency iterators. Thanks [Non-text portions of this message have been removed]
