[igraph] Re: betweenness and degree correlation

[Yong Zou]

Thanks a lot for your prompt reply, Tamas,

Before trying the other method, let me show the error messages for 0.6. :-)

I still have problems when install this:
drl_layout.cpp:27:24: error: drl_layout.h: No such file or directory
drl_layout.cpp:28:23: error: drl_parse.h: No such file or directory
drl_layout.cpp:29:23: error: drl_graph.h: No such file or directory
drl_layout.cpp:36: error: ‘drl’ is not a namespace-name
drl_layout.cpp:36: error: expected namespace-name before ‘;’ token
drl_layout.cpp: In function ‘int igraph_layout_drl(const igraph_t*,
igraph_matrix_t*, igraph_bool_t, igraph_layout_drl_options_t*, const
igraph_vector_t*, const igraph_vector_bool_t*)’:
drl_layout.cpp:420: error: ‘graph’ is not a member of ‘drl’
drl_layout.cpp:420: error: expected `;' before ‘neighbors’
drl_layout.cpp:421: error: ‘neighbors’ was not declared in this scope
make[3]: *** [libigraph_la-drl_layout.lo] Error 1

I'll try the other way you suggested.

Best,
Yong
