The code has already been written by others, you just have to use it Next, make sure that pkg-config can correctly report the compilation flags needed to link to igraph; the following command should list a bunch of compiler and linker flags instead of … Add details and clarify the problem by editing this post.

You need to tell your system where to search for QGIS libraries and appropriate Python modules if they are not in a well-known location - otherwise Python will complain: >>>importqgis.core ImportError: No module named qgis.core This can be fixed by setting the PYTHONPATHenvironment variable.
