[igraph] : Reading File GraphML

[patricia]

I installed the libxml2 library and set the CodeBlocks as I did for the igraph and yet after running the following test code: 

#include <cstdio> 

#include "igraph.h" 

using namespace std; 

int main () 

{

     igraph_t g; 

     FILE * ifile; 

     ifile = fopen ("GraphML-hsa05010.xml", "r"); 

     igraph_read_graph_graphml (&g, ifile, 0); 

     fclose (ifile); 

     igraph_destroy (&g); 

   return 0; 

} 

I get the same error message:  

"Error at foreign-graphml.c:1211 : GraphML support is disabled, unimplemented function call " 

"39512 [main] TesteGraphML 5372 cygwin_exception :: open_stackdumpfile : Dumping stack trace to TesteGraphML.exe.stackdump"

0022A8C8  610DAEDD (00000000, 00000000, 00000004, 00000000)  

What should I do?

Thank you
