Re: [igraph] Error at iterators.c

[Sana Rahim]

Thank you for reply. But when i initialize it i get segmentation fault.

#include<igraph.h>
void main()
{
igraph_t graph;
igraph_vector_t v;
igraph_vector_ptr_t res;
igraph_vector_t nrgeo;

igraph_real_t edges[] = {1, 2, 1, 4, 2, 3, 3, 7, 4, 5, 5, 6, 6, 9, 7, 8, 8, 9};

igraph_vector_view(&v, edges, sizeof(edges)/sizeof(double));

igraph_create(&graph,&v, 0, IGRAPH_UNDIRECTED);


igraph_get_all_shortest_paths(&graph, &res, &nrgeo, 1, igraph_vss_seq(2,8), IGRAPH_ALL);

igraph_destroy(&graph);

}

Regards,

Hi, thanks for immediate reply. How should I initialize vs? When i initialize it like igraph_vs_t vs=3 or give value to vs , it says invalid initializer.

You never initialize vs.

Where am I making a mistake, please help.
