Hi I m trying to extract a graph by reading out graphml. For this purpose i'm making using of graphml.cpp and graphml.hpp also i have included "expat" libraries required for this. But when i'm trying to compile this it gives the following error :- Executing make... make.exe -f "C:\Dev-Cpp\graphml\Makefile.win" all g++.exe -D__DEBUG__ -c ../../boost_1_34_1/libs/graph/src/graphml.cpp -o ../../SRLGrp/BoostLib/boost_1_34_1/libs/graph/src/graphml.o -I"C:/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -I"C:/Dev-Cpp/include/c++/3.4.2/backward" -I"C:/Dev-Cpp/include/c++/3.4.2/mingw32" -I"C:/Dev-Cpp/include/c++/3.4.2" -I"C:/Dev-Cpp/include" -I"C:/Dev-Cpp/graphml" -I"C:/SRLGrp/BoostLib/expat-2.0.1/lib" -I"C:/SRLGrp/BoostLib/boost_1_34_1" -I"C:/SRLGrp/BoostLib/expat-2.0.1" -pg -g3 In file included from ../../SRLGrp/BoostLib/boost_1_34_1/libs/graph/src/graphml.cpp:14: C:/SRLGrp/BoostLib/boost_1_34_1/boost\graph\graphml.hpp: In function `void boost::write_graphml(std::ostream&, const Graph&, VertexIndexMap, const boost::dynamic_properties&, bool)': C:/boost_1_34_1/boost\graph\graphml.hpp:259: error: missing terminating " character C:/boost_1_34_1/boost\graph\graphml.hpp:260: error: `xmlns' undeclared (first use this function) C:/boost_1_34_1/boost\graph\graphml.hpp:260: error: (Each undeclared identifier is reported only once for each function it appears in.)

Right now i m only trying to compile the code avaliable on boost website.
