Hello,

  I couldn't compile libpcap-current.tar.gz (2000.08.22) on
BSD/OS 3.1.


  Error message is as follows:

--- cut here ---
shlicc2 -O2 -I. -DHAVE_CONFIG_H -c ./inet.c
./inet.c: In function `pcap_lookupdev':
./inet.c:98: `IF_NAMESIZE' undeclared (first use this function)
./inet.c:98: (Each undeclared identifier is reported only once
./inet.c:98: for each function it appears in.)
./inet.c:98: size of array `device' has non-integer type
*** Error code 1

Stop.
--- cut here ---


  This is because BSD/OS 3.1 has old-fashioned include files which
has no IF_NAMESIZE defined in /usr/include/net/if.h.
KAME modified BSD/OS 3.1 has IF_NAMESIZE.

  I wrote a ad hoc patch. But I think there will be a better way
to correct this bug.


Thanks in advance.
