I don't have g++-4.3 installed. When building ipython: walktrap_graph.cpp: In member function 'void Graph::convert_from_igraph(const igraph_t*, const igraph_vector_t*)': walktrap_graph.cpp:167: error: 'sort' was not declared in this scope walktrap_graph.cpp: In member function 'long int Graph::memory()': walktrap_graph.cpp:190: error: 'strlen' was not declared in this scope I tried adding: #include <cstring> #include <algorithm> and using std::sort, std::strlen.
