Questions about boost with a vector of pair
by yinglcs2＠yahoo.com 02 Mar '06

02 Mar '06

I am trying to write a function with takes a vector of pair and an key (integer). it should return true if the input key matches the FIRST value of the map. bool containsPair(vector< pair<int, int> >& aMap, int key ) { return ( find_if ( aMap.begin(), aMap.end(), bind( equal_to<int>(), boost::lambda::bind( &pair< int, int>::first_type::first, boost::lambda::_1) , key ) ) != aMap.end()); } But i cant' get the code to compile. I have this error: ../RowColumn1_4PatternMatcherHelper.h: In function bool containsPair(std::vector<std::pair<int, int>, std::allocator<std::pair<int, int> > >&, int): ../RowColumn1_4PatternMatcherHelper.h:62: error: struct std::pair<int, int>::first_type is not a class or namespace ../RowColumn1_4PatternMatcherHelper.h:62: error: first was not declared in this scope make: *** [TestDriver.o] Error 1 any help is appreciated. __________________________________________________ Do You Yahoo!?

BGL connected_components for directed graphs
by Gavin Band 02 Mar '06

02 Mar '06

Dear boosters, I am trying to compile a program which is identical to the example http://www.boost.org/libs/graph/example/connected_components.cpp given in the docs, except that in the graph typedef I changed undirectedS to directedS. However, I get a compilation error: g++ -o test_c++.o -I/usr/include/boost -c test_c++.cpp /usr/include/boost/graph/connected_components.hpp: In function `typename boost::property_traits<IndexMap>::value_type boost::connected_components(const Graph&, ComponentMap) [with Graph = main(int, char**)::Graph, ComponentMap = int*]': test_c++.cpp:45: instantiated from here /usr/include/boost/graph/connected_components.hpp:87: error: incomplete type `boost::STATIC_ASSERTION_FAILURE< false>' used in nested name specifier /usr/include/boost/graph/connected_components.hpp:87: error: size of array has non-integral type `<type error>' Presumably this is some meta-program's way of telling me that my graph isn't undirected. Is there any way to make this work for an directed graph? (I am using gcc 3.4.4 and boost 1.33.0) Thanks, Gavin Band.

[multi_index] Trouble using MultiIndex with Visual Studio 2005
by Andrew Holden 02 Mar '06

02 Mar '06

I am trying to compile a program using MultiIndex from Boost 1.33.1 using Visual Studio 2005 (MSVC8). So far, I can not get it to compile with fewer than 100 errors. Does anyone know what I might be doing wrong? I have attached the source file I am using to test, as well as the output from my compiler. Andrew Holden Charter Oak Investment Systems, Inc.

FW: adjacency_list remove_edge
by Sean Kelly 02 Mar '06

02 Mar '06

Hi All, I have observed the following behavior using the remove_edge function and am curious if anyone else has seen this. remove_edge(edge_descriptor, graph) // occasionally fails in a seemingly indeterminant way remove_edge(source(edge_descriptor, graph), target(edge_descriptor, graph), graph) // works fine The adjacency list I am using is listS listS, and this is not an issue with invalid edge_iterators, i.e. I collect all the edge_descriptors to be removed before removing them. I can provide more detailed info upon request. thanks for any input Sean Kelly Sean Kelly Ph.D. Staff Software Engineer Xilinx Inc. ph: 720-652-3919 fax: 720-652-3434

If I specify the name of the library on the command line, as you suggest, this doesn't solve the problem (same results). Therefore, an incorrect library selection doesn't seem to be the problem by the linker.

serialization: again a problem, failing to serialize a std::vector of pointers
by RIVASSEAU Jean Noel 02 Mar '06

02 Mar '06

Hello This is my last problem with the BSL but the most important one (because there is no workaround). I am trying to serialize a class (whose name is "ClassSpecification") which has a std::vector of pointers. The code for serializing the class the pointer refer to (MemberVariableSpecification) is written and instantiated correctly. However I cannot correctly serialize the std::vector. It fails with a message complaining about: C:/Boost/include/boost-1_33_1/boost/archive/detail/iserializer.hpp:115: error: incomplete type `boost::serialization::extended_type_info_null<std::vector<MemberVariableSpecification*, std::allocator<MemberVariableSpecification*> > >' used in nested name specifier I do not understand why I need an extended_type_info for this vector. I sure need it for the class the pointers refer to (and I did specify it), but the std::vector itself is serialized as such, not as a pointer. Why do I get this error ??? Can you please check the attached code and help me? Thanks Jean-Noël Ps: using gcc 3.4.2

[serialization] non-intrusive serialization problem
by Federico Feller 02 Mar '06

02 Mar '06

Hi. I have problems defining a non-instrusive serialization of a class. Ive defined the following functions: namespace boost { namespace serialization { template<class Archive> inline void save( Archive & ar, const CLITimeStamp & t, const unsigned int /* file_version */ ){ std::string aux = std::string(t.get14LengthRepresentation()); ar & aux; } template<class Archive> inline void load( Archive & ar, const CLITimeStamp & t, const unsigned int /* file_version */ ){ std::string aux; ar & aux; t = CLITimeStamp((char*)aux.c_str()); } template<class Archive> inline void serialize( Archive & ar, const CLITimeStamp & t, const unsigned int file_version ){ split_free(ar, t, file_version); } }} According to the doc Ive read, this is the way to declare that the class 'CLITimeStamp' can be serialized. Howerver, when I try to do this: template<class Archive> void load(Archive & ar, const unsigned int version){ ar & minDate }; where minDate is a CLITimeStamp pointer, i get the follwing error: <'serialize' is not a Member of CLITimeStamp> Any ideas of what i could be doing wrong? Thanks Federico __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Just trying to use mpl::transform on a vector of int's and I can't seem to get it working properly. Can anyone see what's wrong?? I'm trying to perform vector_c<int, 1, 2, 3> + vector_c<int, 1, 1, 1> = vector_c<int, 2, 3 ,4> The is_same function always returns false when I compile and run it. ------------------- typedef mpl::vector_c<int, 1, 2, 3> type_a; typedef mpl::vector_c<int, 1, 1, 1> type_b; struct plus_f { template<class A, class B> struct apply { typedef typename mpl::plus<A, B>::type type; }; }; typedef mpl::transform<type_a, type_b, plus_f >::type result_type; std::cerr << "True " << boost::is_same<result_type, mpl::vector_c<int, 2, 3, 4> >::value << std::endl; __________________________________________________ Do You Yahoo!?

Re: [Boost-users] Boost can't build with Intel C++ Compiler 9.0

I'm in the middle of building on an Altix (Itanium, Linux) with Intel 9.0 also. Still checking but this looks like it's working for me: bjam -sTOOLS=intel-linux "-sINTEL_CC=icc -cxxlib-icc" -sINTEL_PATH=/opt/intel/cc/9.0 But I guess you have a reason for not wanting to use bjam. Hope this helps.
