Hi all,
I was trying to compile the net-snmp souce code with the module
'disman/ping-mib' added.
./configure --prefix=/usr --with-mib-modules=disman/ping-mib
But I failed with such 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
In file included from disman/ping/pingCtlTable.c:44:
disman/ping/pingCtlTable.h:98:17: in6.h: No such file or directory
disman/ping/pingCtlTable.h:99:18: ipv6.h: No such file or directory
disman/ping/pingCtlTable.c: In function `parse_reply':
disman/ping/pingCtlTable.c:5679: error: invalid use of undefined type
`struct ipv6hdr'
disman/ping/pingCtlTable.c:5689: error: invalid application of `sizeof'
to an incomplete type
disman/ping/pingCtlTable.c:5692: error: dereferencing pointer to
incomplete typedisman/ping/pingCtlTable.c:5695: error: dereferencing
pointer to incomplete typemake[2]: *** [disman/ping/pingCtlTable.lo] Error 1
make[2]: Leaving directory `/root/net-snmp-5.2.1.2/agent/mibgroup'
make[1]: *** [subdirs] Error 1
make[1]: Leaving directory `/root/net-snmp-5.2.1.2/agent'
make: *** [subdirs] Error 1
Obviously, the included files are missing. Then I opened the file
`pingCtlTable.h', here's the code snippet:
/* #include <linux/in6.h> */
/* #include <linux/ipv6.h> */
#include "in6.h"
#include "ipv6.h"
After viewing the above code, I would tend to think that the author
originally had two methods to handle the headers. Therefore I changed
the above code to:
#include <linux/in6.h>
#include <linux/ipv6.h>
/* #include "in6.h" */
/* #include "ipv6.h" */
But I still failed with the error shown below:
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

make[1]: Leaving directory `/root/net-snmp-5.2.1.2/agent'

The re-definition error.
I'm puzzled.
Anyone who knows how to solve the problem? Thanks in advance.
Best regards,
Guanqun Lu
