Re: [igraph] Re: igraph, visual studio c++ and libxml2

[Tamás Nepusz]

This does not seem to be an igraph-related problem; it is more like a
general problem with Visual Studio and/or the configuration you are usig
when compiling your project. First, try building both igraph and your
project in release mode (instead of debug mode) and see if that resolves
your problem.
