Re: Fwd: present but cannot be compiled

[Akim Demaille]

| Hi,
| I'm using Mac OS X 10.2.6 (Darwin / Jaguar) and got an error from
| autoconf. Nmap actually compiles and works ok, so this is just a
| cosmetic problem..(?)
| 
| Akim: Looks like netinet/if_ether.h requires stdio.h and sys/socket.h:
| 
| bash-2.05a$ cat s.c
| #include <stdio.h>
| #include <sys/socket.h>
| #include <netinet/if_ether.h>
| 
| int main () {}
| bash-2.05a$ gcc s.c ; rm a.out
| bash-2.05a$
| 
| (Sorry about spamming a bit)

Thanks a lot, I'm including the following in Autoconf's documentation.
