Description Vaibhav Khanduja 2005-04-27 02:19:47 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3

Description of problem:
I am trying to execute ldd on one of my executable it is printing false output.

ldd ./rpcd
        not a dynamic executable



Version-Release number of selected component (if applicable):
ldd

How reproducible:
Always

Steps to Reproduce:
1.execute ldd on any executable which has some shared objects linked.
2.
3.
  

Actual Results:  ldd prints  "not a dynamic executable"

Expected Results:  Should have given all the shared objects the executable links.

Additional info:

The kernel 2.4.21-27 panics when any 32 bit application runs, I have the fix specified in 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=149965. 

But this ldd issue I could see even before applying the fix.

Hello, Vaibhav.  Here's the output I get from "ldd /bin/ls":

        libacl.so.1 => /lib/libacl.so.1 (0x0064a000)
        libtermcap.so.2 => /lib/libtermcap.so.2 (0x00864000)
        libc.so.6 => /lib/tls/libc.so.6 (0x00217000)
        libattr.so.1 => /lib/libattr.so.1 (0x00a0c000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00201000)

Perhaps you're not running "ldd" on an appropriate executable.

At any rate, this is not a kernel problem, so I'll reassign this to
the "glib" component (since /usr/bin/ldd is in the glibc-common RPM).
Comment 2 Vaibhav Khanduja 2005-04-28 01:21:39 EDT
I am actually running ldd on a correct executable. I had actaully moved from
2.4.21-15 to 2.4.21-27. I just checked on 2.4.21-15 it is not working there
either. There might be something glibc. I have glibc-common-2.3.2-95.20
installed  on my system. 
Comment 3 Vaibhav Khanduja 2005-04-28 10:50:42 EDT
I guess I have figured out why ldd is not working for me. We are running our
application in emulated mode, a 32 bit on 64bit platforms. We pick some of the
libraries from /emul/ia32-Linux/lib. ldd is a script which by default is not
checking in this directory a small change in ldd would make this happen. The
change is listed below 30 should look like 
line number 
RTLDLIST="/emul/ia32-linux/lib/ld-linux.so.2 /lib/ld-linux-ia64.so.2
/lib/ld-linux.so.2"

instead of 
RTLDLIST="/lib/ld-linux-ia64.so.2 /lib/ld-linux.so.2"

I guess this fix should be added in the next release.
Comment 4 Jakub Jelinek 2005-05-13 12:45:47 EDT
It was actually already added in RHEL3 U3.
Make sure you use glibc{,-common}-2.3.2-95.27 or newer.
