This got thown around the office a bit (I thouht it interesting
information) and the following information was broadcast internally.  I
thought if of such general interest that I am forwarding it on to this
list:

An example of this is the "xv" utility distributed via the Freeware CD.
Using "odump -Dl vx" you get:


			    ***LIBRARY LIST SECTION***
	    Name             Time-Stamp        CheckSum   Flags Version
    xv:
	    libXext.so   Feb  4 23:10:08 1993 0x67dc0626  NONE 
	    libX11.so    Feb  4 23:05:53 1993 0x7ddb5498  NONE 
	    libm.so      Feb  4 15:29:46 1993 0x254d7617  NONE osf.1
	    libc.so      Feb 24 10:04:26 1993 0x545dfc37  NONE osf.1

Using "dbx" and the "listobj" command you get:

    dbx version 3.11.4
    Type 'help' for help.

    main:   Source not available
    (dbx) listobj
    xv              addr: 0x120000000       size: 0xba000 
    /usr/shlib/libXext.so           addr: 0x3ff80800000     size: 0xe000 
    /usr/shlib/libX11.so            addr: 0x3ff81000000     size: 0x8a000 
    /usr/shlib/libm.so              addr: 0x3ff80810000     size: 0x40000 
    /usr/shlib/libc.so              addr: 0x3ff81800000     size: 0xbc000 
    /usr/shlib/libdnet_stub.so              addr: 0x3ff80940000     size: 0x4000 
    (dbx) quit

Note that the "libdnet_stub.so" does not show from odump.

Enjoy,
