RE: segmentation fault

Yes Michael I ran make clean, as I told you I reinstall everything again in
a pc with a fresh and new RH9 instalation, and again I get the same
segmentation fault. I really don't know what's happening the only thing I
can think is about the way I build the opensnmp code I used:

./configure --with-db=/usr/local/BerkeleyDB.4.1/lib
make
make install

I also tried adding the following specifications:

--sysconfdir=/etc
--prefix=/usr

Everytime I tried this different specifications I ran make clean fisrt

I also tried the opensnmp rpms, with the respective devel rpms

I tried everything and still with the problem, so I will need your help
regarding the output messages I sent you, considering you made that codes
you are the one that can suggest from where comes the problem.

The last thing that comes in my mind is that I'am using the net-snmp rpms,
so don't know if that can affect, I had to use the rpms, because I was
having problems adding the snmpd deamon to the deamons start list, when I
build it from source.

Please tell me if SNMP have something to do with this problem, or as you can
saw in the segmentation fault messages, it's a particular of OPENSNMP. I
don't care if I have to reinstall everything again, if it's necesary, but
first need to make sure what the problem is.

Considering you didn't get these messages, maybe it's something I'am doing
wrong.

I re-read the error message you sent earlier and another thought
occurred to me.  Have you run 'make clean; make' in the opensnmp/
directory?  The change I sent previously will not likely work
without a make clean.
