/usr/lib/dld.sl: Exec format error

[Srinivas Sreekumar]

On one of the HP UX11i server, when we execute the command
export SHLIB_PATH=/usr/lib/pa20_64:$SHLIB_PATH
and then execute
ldd
we get the following error message:
/usr/lib/dld.sl: Bad magic number for shared library: /usr/lib/pa20_64/libc.2
/usr/lib/dld.sl: Exec format error

However, if we execute the command
export SHLIB_PATH=/usr/lib:$SHLIB_PATH
and then execute
ldd
we get the following:
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/informix/lib/esql/libifglx.sl => /usr/informix/lib/esql/libifglxl

../ts_lib/libclient.sl => /appl/sp/lib/libclient.sl
/appl/sp/lib/libuniconv.sl => /appl/sp/lib/libuniconv.sl

Does this signify that the libc.2 library present in /usr/lib/pa20_64 is corrupted? If not, then what is the reason for the bad magic error? Kindly clarify

Hi



You need to
export or setenv LPATH to /usr/lib/pa20_64

[ranganath ramachandra]

the problem is you are running ldd on a PA32 executable, the dld found libc.2 in /usr/lib/pa20_64 first and saw that it is not good for a PA32 executable.

use SHLIB_PATH for specifying PA32 shared library lookup paths and LD_LIBRARY_PATH for PA64 shared library lookup paths.

it is better not to include the standard library lookup paths (/usr/lib for PA32 and /usr/lib/pa20_64 for PA64) in these variables.
