Converting GraphML to GV or Dot file

graphml, graphviz

Solution

Your copy of Graphviz was compiled without the Expat library (to redress, install Expat and recompile after running `./configure --with-expat=yes`).

cmd/tools/graphml2gv.c:

#ifdef HAVE_EXPAT
    initargs(argc, argv);
    while ((inFile = getFile())) {
    while ((G = graphml_to_gv(nameOf(gname, gcnt), inFile, &rv))) {
        gcnt++;
        if (prev)
        agclose(prev);
        prev = G;
        if (Verbose) 
        fprintf (stderr, "%s: %d nodes %d edges\n",
            agnameof (G), agnnodes(G), agnedges(G));
        agwrite(G, outFile);
        fflush(outFile);
    }
    }
    exit(rv);
#else
    fputs("cvtgxl: not configured for conversion from GXL to GV\n", stderr);
    exit(1);
#endif

Problem

How can I draw a graph in graphviz using "graphml" file as an input. I know `graphviz` comes with `graphml2gv` for this purpose but when I try to run this command from command prompt I get this message `cvtgxl: not configured for conversion from GXL to GV`
