Hi all,
I've googled and had a quick leaf through the mailing list archives to
see if this has been a problem before, but not found any reference to
it.
When compiling net-snmp 5.2.1 on a Debian (woody) linux machine with
gcc 3.3.5, configured with "configure --with-mib-modules="host
disman"" I'm getting the following errors -
gcc -I../../include -I. -I../../agent -I../../agent/mibgroup
-I../../snmplib -g -O2 -Dlinux -c disman/ping/pingCtlTable.c -fPIC
-DPIC -o disman/ping/.libs/pingCtlTable.lo

>From pingCtlTable.h -

96 /* #include <linux/ipv6.h> */
97
98 #include "in6.h"
99 #include "ipv6.h"
the missing ipv6hdr struct is indeed defined in
/usr/include/linux/ipv6.h, but changing line 99 in the above file to -
#include <linux/ipv6.h>
results in some redifinitions -
gcc -I../../include -I. -I../../agent -I../../agent/mibgroup
-I../../snmplib -g -O2 -Dlinux -c disman/ping/pingCtlTable.c -fPIC

I've also tried the same with the in6.h file, to no avail. I'm a bit
stuck as to how I might fix this, short of copying the ipv6hdr struct
from the kernel headers to a header in the net-snmp source. It isn't
defined in any other header on my system. I would have thought it
might have been provided under /usr/inlcude/netinet somewhere, but its
not. I'm guessing that whereever in6_addr, sockaddr_in6, ipv6_mreq
and in6_pktinfo are defined I should also have ipv6hdr, or am I way
off the mark in thinking that ?
Any pointers much appreciated.
cheers,
