[igraph] install igraph on mac

[Yong Zou]

Dear Tamas,

I'd like to have you help since I can't compile my programs which
previously worked in linux systems.

I downloaded the c code from your site,
For Mac OS 10.6.6,
I suppose it has been correctly installed, because
(1) which igraph
/usr/local/bin/igraph
(2) pkg-config --libs --cflags igraph
-I/usr/local/include  -L/usr/local/lib -ligraph

However, when I compile my code with
gcc myfile.c -I/usr/local/include  -L/usr/local/lib -ligraph -o myfile
myfile.c:7:20: error: igraph.h: No such file or directory

Can you please help me with this? Thanks in advance.

Best regards,
Yong
