[igraph] C library Install on OS X

Hi All,

I can't install C library to OS X Snow Leopard. I followed the steps in the manuel like configure, make, make install.

At the make install step on terminal I get the following error:

Making install in src
make  install-am
test -z "/usr/local/lib" || .././install-sh -c -d "/usr/local/lib"
 /bin/sh ../libtool   --mode=install /usr/bin/install -c   libigraph.la '/usr/local/lib'
libtool: install: /usr/bin/install -c .libs/libigraph.0.dylib /usr/local/lib/libigraph.0.dylib
install: /usr/local/lib/libigraph.0.dylib: Permission denied
make[3]: *** [install-libLTLIBRARIES] Error 71
make[2]: *** [install-am] Error 2
make[1]: *** [install] Error 2
make: *** [install-recursive] Error 1

At the same time I try to compile and run the following code using Xcode. Apparently it doesn't work.

#include <iostream>
#include <igraph.h>

int main(void
{

igraph_real_t diameter; igraph_t graph; 
igraph_erdos_renyi_game(&graph, IGRAPH_ERDOS_RENYI_GNP, 1000, 5.0/1000,
IGRAPH_UNDIRECTED, IGRAPH_NO_LOOPS); 
igraph_diameter(&graph, &diameter, 0, 0, 0, IGRAPH_UNDIRECTED, 1);
printf("Diameter of a random graph with average degree 5: %f\n", (double) diameter);
igraph_destroy(&graph); return 0;
}

Any help? Thank you.

Harun
