Hi,
I downloaded libpcap 0.7.1, and tried to build on my (almost ancient)
Linux kernel 2.0.39, and stumbled across a little glitch.
On Linux 2.0.* /usr/include/linux/if_arp.h doesn't define
'ARPHRD_HDLC', it appears somewhere before Linux 2.2.20.
It's defined in Linux 2.2.20 as:
#define ARPHRD_HDLC 513
My small workaround (at least to get libpcap to compile) was:
jpv@jp-gp: /usr/src/libpcap-0.7.1 # diff -u pcap-linux.c- pcap-linux.c
--- pcap-linux.c- Mon Dec 10 08:14:16 2001

handle->linktype = DLT_LINUX_SLL;
break;
+#ifndef ARPHRD_HDLC
+#define ARPHRD_HDLC 513 /* From Linux 2.2.20 */
+#endif
case ARPHRD_HDLC:
handle->linktype = DLT_C_HDLC;
break;
I couldn't find anything in CVS about this, but did see a more similar
one concerning an ARPHRD_FDDI (IIRC) which didn't exist in Linux 2.2.x
but did in Linux 2.4.x ... It used a similar workaround...

OK, now back to tweaking tcpdump's configure.in to nicely detect
OpenSSL in a 'non-standard' place... ;)
