Re: [igraph] Compilation Issue Using Graph Generation

[Thomas Gorochowski]

Hi

I am using igraph-0.5.2 which I compiled from source in the standard  
way, only altered the prefix location to my development area. My  
system is running Leopard 10.5.7 and compilation of my own code is  
done using XCode. I am not 100% sure of the exact commands that XCode  
uses but I have managed to recreate the problem using the following  
program and compilation command from the terminal. If I use g++  
instead of gcc it compiles fine. I'm sure it is probably the way I  
have created the static library but some direction would be great.

C CODE ===========================

#include <stdlib.h>
#include <igraph.h>

int main (int argc, const char * argv[])
{
        igraph_t *G;
        G = (igraph_t *)malloc(sizeof(igraph_t));
	igraph_erdos_renyi_game(G, IGRAPH_ERDOS_RENYI_GNM, 100, 400,  
IGRAPH_UNDIRECTED, IGRAPH_NO_LOOPS);
        return 0;
}

COMPILE COMMAND ===========================

gcc -I ~/Work/Complexity/Development/libs/include/igraph/ -L ~/Work/ 
Complexity/Development/libs/lib/libigraph.a test.c

Many thanks,

Tom
