Hi Roberto,

if you only tried to install it, but failed, then it will obviously
not work. First make sure that you really installed it. E.g. if there
was no error message after running 'make install', then it was
installed properly. Then look for the directory that has igraph.h and
give that directory for the -I switch.

Best,
Gabor
