Re: Compilation issue on Mac OS

[ajay saxena <aileronajay () gmail com>]

Hi Guy,

Though i do think, this might have to do something with the wireshark code
base too. For example I created this file

#include <gcrypt.h>
#include <stdio.h>
#include <GeoIP.h>
#include <ares.h>
 int main(){
printf("Hello World");
return 0;
}

as importtest.c and on compiling with gcc (clang), the file does get
compiled. Here is the verbose output from that compile

Ajays-MacBook-Pro:scripts ajasaxen$ gcc -v importtest.c -o importtest

and in this compile /usr/local/include was searched. Whereas when it
compiles wireshark, it does not search in /usr/local/include.

Thanks,
Ajay
