My command is: ./graph flow.c | ./gvpr/return-paths graph does not generate XML. It generates graphviz output. You need graphviz to work with it; graphviz also includes gvpr. You do not need to process the output further; you simply have the option of doing so. You can directly feed the output of graph to "dot" or one of the other graphviz tools to get an image. However, I agree that no obvious connection exists between the "graph" program and the post-processing scripts in gvpr. - Josh Triplett -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
