 ##### `make` terminates with `fatal error: igraph.h: No such file or directory`#####
 Be sure that [igraph][1] header files are placed in a standard system include directory. If these headers are in non-standard places, you have to tell the `gcc` where to find them. Open the `Makefile` and assign to `IGRAPH_INCDIR_1` (or, equivalently, to `IGRAPH_INCDIR_2`) the path to the folder containing [igraph][1] header files on your system.
+
+##### `make` terminates with `ld: cannot find -ligraph` #####
+This is the linker which cannot find the [igraph][1] shared library. Make sure that this library is installed in a directory in the default library path. The directory should be listed in the file `/etc/ld.so.conf`. The [igraph][1] installation procedure should place it in a standard place so you might want to try reinstalling it.
 
 ##### Why does the utility `maximal_cliques` take too long to terminate?#####
 As discussed in [MaximalCliquesListing], the executable `maximal_cliques` uses the [igraph][1] C library to extract maximal cliques. Versions of igraph less than 0.6 (e.g. 0.5.4) do not implement the fast Bron-Kerbosh algorithm. Therefore you should be sure to have at least version 0.6 installed.
