How can I use the Boost Graph Library to lay out verticies?
- by Mike
I'm trying to lay out vertices using the Boost Graph Library. However, I'm running into some compilation issues which I'm unsure about. Am I using the BGL in an improper manner? My code is:
PositionVec position_vec(2);
PositionMap position(position_vec.begin(), get(vertex_index, g));
int iterations = 100;
double width = 100.0;
double height = 100.0;
minstd_rand gen;
rectangle_topology<> topology(gen, 0, 0, 100, 100);
fruchterman_reingold_force_directed_layout(g, position, topology); //Compile fails on this line
The diagnostics produced by clang++(I've also tried GCC) are:
