Re: [igraph] Problems about running the igraph C library

[Tamas Nepusz]

Hello,

This is a known issue with the MSVC buildfile and it is easy to fix; see:

http://stackoverflow.com/questions/26579997/igraph-c-compiling-link-errors-in-visual-studio
http://stackoverflow.com/questions/25260025/build-solution-errorerror-c2065-prpack-igraph-graph-undeclared-identifier

Basically, you will need to add /DPRPACK_IGRAPH_SUPPORT=1 to the compiler
options and add PRPACK's source files from the src/ folder to the project, then
recompile everything.

Best,
T.
