Description Greg Edwards 2004-06-01 16:38:00 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux ia64; en-US; rv:1.8a2)

Description of problem:
/usr/bin/ldd contains:

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


On ia64, /lib/ld-linux.so.2 should be a symlink to 
/emul/ia32-linux/lib/ld-linux.so.2 so ldd will work for ia32-compiled
apps.  Otherwise, the behavior is:

$ file setup
setup: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.0.0, dynamically linked (uses shared libs), stripped

$ ldd setup
        not a dynamic executable

With the symlink in place, the output is correct:

$ ldd setup
        libdl.so.2 => /lib/libdl.so.2 (0x40034000)
        libX11.so.6 => not found
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40038000)
        libm.so.6 => /lib/tls/libm.so.6 (0x40048000)
        libc.so.6 => /lib/tls/libc.so.6 (0x4006c000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

How reproducible:

Steps to Reproduce:
1. Run ldd on an ia32 app on an RHEL AS 3 Update 2 ia64 box

Comment 1 Jakub Jelinek 2004-10-25 10:57:33 EDT
glibc-2.3.2-95.27 and above have:
RTLDLIST="/lib/ld-linux-ia64.so.2 /emul/ia32-linux/lib/ld-linux.so.2"
in /usr/bin/ldd.
