igraph C compiling link errors in Visual Studio

Question

I'm trying to compile an igraph C code in the Visual Studio 2013, already got all libraries included in the properties, just as some examples that come with the distribution of igraph C, but i still got the following problems in the output window:

1>igraph.lib(prpack.obj) : error LNK2001: unresolved external symbol "public: __thiscall prpack::prpack_base_graph::~prpack_base_graph(void)" (??1prpack_base_graph@prpack@@QAE@XZ)
1>igraph.lib(prpack.obj) : error LNK2001: unresolved external symbol "public: __thiscall prpack::prpack_igraph_graph::prpack_igraph_graph(struct igraph_s const *,struct igraph_vector_t const *,int)" (??0prpack_igraph_graph@prpack@@QAE@PBUigraph_s@@PBUigraph_vector_t@@H@Z)

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Obviously it's something related to the prpack, but i have no clue of which library do i need to include, does anyone knows how to solve this?

Answer 1

This is a bug in the MSVC release of igraph; try adding /DPRPACK_IGRAPH_SUPPORT=1 to the compiler options and also add PRPACK's source files from the src/ folder (basically everything that matches prpack_*.cpp) to the list of source files in the project, then recompile.
