[BGL]: adjacency_list_io bug?
Hello everybody! I'm using adjacency_list_io to import my graphs from the disk: typedef boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS > graph_t; graph_t wwwg; //string dataFile("www.bdat"); string dataFile("www_undirected.bdat"); cout << "importing www network from file \"" << dataFile << "\" ... "; ifstream wwwDatIn(dataFile.c_str()); wwwDatIn >> read( wwwg ); wwwDatIn.close(); This works nicely with g++ 3.3, but g++ 4.0 refuse to compile this code and chokes with an error message like /home/sebi/projects/diplom/src/boost_1_33_1/boost/graph/adjacency_list_io.hpp: In member function 'boost::GraphParser<Graph_t, VertexProperty, EdgeProperty, VertexPropertySubset, EdgePropertySubset>& boost::GraphParser<Graph_t, VertexProperty, EdgeProperty, VertexPropertySubset, EdgePropertySubset>::operator()(std::istream&) [with Graph_t = boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS, boost::no_property, boost::no_property, boost::no_property, boost::listS>, VertexProperty = boost::no_property, EdgeProperty = boost::no_property, VertexPropertySubset = boost::no_property, EdgePropertySubset = boost::no_property]': /home/sebi/projects/diplom/src/boost_1_33_1/boost/graph/adjacency_list_io.hpp:327: instantiated from 'std::istream& boost::operator>>(std::istream&, boost::GraphParser<Graph, VP, EP, VPS, EPS>) [with Graph = boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS, boost::no_property, boost::no_property, boost::no_property, boost::listS>, VP = boost::no_property, EP = boost::no_property, VPS = boost::no_property, EPS = boost::no_property]' I have no clue where this comes from, but it seems to be some incompatibility between g++ 4.0 and adjacency_list_io. Would be nice if someone could enlighten me or fix it. Thanks! Sebastian My system: Ubuntu 5.10, Boost 1.33.1, anything else needed?

Simple: don't define the State type locally to the function. If the type depends on some template parameters of the function, e.g. class State : public foo<VertexProperty> { ... }; you can just define it outside the function as: template <class VertexProperty> class State_ : public foo<VertexProperty> { ... }; and then in the function: typedef State_<VertexProperty> State;

I use STLFilt with g++-4 with success.
And gcc-3.3 (and 3.4) DOES compile my code without any complaints.
Not to be blunt, but so what? That doesn't make your code right.

Hi! It turned out that the enum-definition typedef enum{ PARSE_NUM_NODES, PARSE_VERTEX, PARSE_EDGE } State; which was placed inside the GraphParser::operator() method caused all the trouble. Once I moved that definition outside the function body into the class-defintion, everything worked as it should. I attached the corresponding patch. Would someone please check this and then commit this into cvs boost?

I was just saying that I did not write the code - it was original boost-code.
I use STLFilt with g++-4 with success.
Good to know, the specs on the web-site are then outdated. Thanks, Sebastian

How does it happen that Boost code is using CamelCase for types? That's what confused me about the original post. -- Dave Abrahams Boost Consulting www.boost-consulting.com
