Hi there,

I am having difficulty writing to a .dot file. After typing in the follwoing code (following the example in the book, p.85).

write_graphviz("ECgraphs/test_network.dot",angle_list);

I get the following error message:

Error 89 error C2664: 'boost::write_graphviz' : cannot convert parameter 1 from 'const char [26]' to 'std::ostream &'

What code do I have to write to convert my 'const char [26]' to a 'std::ostream &'?

#include <fstream> ... std::ofstream out("ECgraphs/test_network.dot"); write_graphviz(out, angle_list); HTH, Doug
