Hello, I encounter some problems when porting an application using boost from Windows to Linux. I work with Ubuntu, I use codeblocks as a compiling environment. The boost library I use is boost_1_38 containing boost_1_38/boost/property_map.hpp boost_1_38/boost/config.hpp boost_1_38/boost/graph/adjacency_list.hpp boost_1_38/boost/graph/graph_utility.hpp. I believe the boost library is compatible with Windows and Linux. The compiler reports the following errror: .../structure_learning/src/graph_tools/GraphPDAG.cpp:295 erreur: conversion from "boost::adj_list_edge_property_map<boost::bidirectional::tag, boost::detail::error_property_not_found, boost::detail::error_property_not_found&, void*, boost::property<boost::edge_weight_t, long double, boost::no_property>, boost::edge_bundle_t" to non-scalar type "boost::no_edge_bundle" requested. Then, it finds a second error: .../structure_learning/src/graph_tools/GraphPDAG.cpp:296 erreur: "struct boost::no_edge_bundle" has no member named "ambiguous". Finally, the third error is (after verbose comments which I can not copy here): GraphPDAG.cpp:296: instantiated from here: boost_1_38/boost/graph/adjacency_list.hpp:463:erreur:invalid initialisation of reference of type "boost::no_edge_bundle&" from expression of type "boost::detail::error_property_not_found". Do you have any idea why this code is correct with Windows but not with Linux ? I would have thought that the boost C++ library is compatible with any system. Thank you in advance for considering my questions. Best regards, C.S. //============================================================================== void PDAG::putWeightPDAG(slBayesianNetwork* bn, slEdge e, int w) { unsigned int a, b; this->pBN = bn; this->getEdgeNodesIndex(e, a, b); this->putWeightPDAG(a, b, w); slGraph& graph = bn->get_graph(); property_map<slGraph, edge_weight_t>::type weightMap = get(edge_weight, graph); line 295 >>>>> edge_bundle_type<slGraph>::type ambiguousTypeMap = get(edge_bundle, graph); line 296 >>>>> graph[e].ambiguous = true; }
