ethereal: symbol "pcap_version"

Bound to be a newbie question i have been running red hat 9 for a week!

OK, i have made some adjustments to the local network cards by adjusting the subnetmask. A change recently made to our LAN so that we can increase our address range. I was plesently surprised whilst reading the red hat 9 bible to find a wonderful utility called ethereal.

however, every time i type

$ethereal &

i get the GUI login screen and ethereal starts to load. However, in the terminal window i see the following.

$ethereal: Symbol "pcap_version" has different size in shared object, consider re-linking

The program runs fine and i am getting data in the capture screen. However, i do like to understand why a message appears plus i can find nothing in the the red hat book about re-linking. may i ask someone to explain.

version of ethereal is 0.9.8
linux 2.4.20-8

if you really need to get rid of the message, download the source for it and re-compile. IF it does compile and installs correctly the message will go away. You get those things time to time when installing stuff from RPM since RPMs are binaries, more or less.

On the other hand, if it works fine, why bother.

Thanks Mikhail_16,

i just like to understand what the command is saying however, and this process of relinking?

Anyway, i found an updated rpm package which is version 0.10.0a. I have downloaded this package and issued the following commands.

su root
#rpm Uvv ethereal-0.10.0a-1.RH9.src.rpm

this is the responce generated..

[root@dtbir3870 downloads]# rpm -Uvv ethereal-0.10.0a-1.RH9.src.rpm
D: ============== ethereal-0.10.0a-1.RH9.src.rpm
D: Expected size: 4390949 = lead(96)+sigs(180)+pad(4)+data(4390669)
D: Actual size: 4390949
D: ethereal-0.10.0a-1.RH9.src.rpm: MD5 digest: OK (e5fa76c2814e4602a1720ffe2dbeb6b8)

GZDIO: 537 reads, 4395824 total bytes in 0.097 secs

I then rebooted the system typed ethereal & only to find i am still running the same version 0.9.8

so i then issued the command
# rpm -ivv ethereal-0.10.0a-1.RH9.src.rpm

I get exactly the same screen as above but i still have the old version installed not the new one. This is clearly a newbie error could anyone help.
