My LeetCode Notebook in C++.

Download

Currently, I am testing igraph-0.7.1-msvc. http://igraph.org/c/#downloads

Compile the igraph library

1. Open the igraph.sln solution file in igraph-0.7.1-msvc from Visual Studio 2013. Let the Visual Studio convert the solution file for you.
2. Add a compiler option (for both Debug and Release): Open Project menu -> Properties -> C/C++ -> Command Line. In Additional options, add the following option: “/DPRPACK_IGRAPH_SUPPORT=1” (without the quotes)
3. Debug -> Build and Release -> Build
