I generated my shared library in 64bit on AIX, but when I ran ldd, it says:
Could not load program libmylib.so:
Could not load module libmylib.so.
The module has an invalid magic number.
Anyone knows how to list library dependencies with 64bit shared library on AIX?

ldconfig
LDCONFIG(8) BSD System Manager's Manual LDCONFIG(8)NAME
ldconfig -- configure the a.out shared library cache
SYNOPSIS
ldconfig [-cmrsSv] [directory ...]
DESCRIPTION
ldconfig is used to prepare a set of ``hints'' for use by the a.out run-time linker ld.so to facilitate quick lookup of shared libraries
available in multiple directories. ldconfig is only available on systems that use the ``a.out'' format for executables and libraries - on
ELF systems, all the work is done by ld.elf_so.
By default, it scans a set of built-in system directories, directories listed in /etc/ld.so.conf, and any directories specified on the com-
mand line (in the given order) looking for shared libraries and stores the results in the file /var/run/ld.so.hints to forestall the overhead
that would otherwise result from the directory search operations ld.so would have to perform to load required shared libraries.
The shared libraries so found will be automatically available for loading if needed by the program being prepared for execution. This obvi-
ates the need for storing search paths within the executable.
The LD_LIBRARY_PATH environment variable can be used to override the use of directories (or the order thereof) from the cache or to specify
additional directories where shared libraries might be found. LD_LIBRARY_PATH is a ':' separated list of directory paths that are searched
by ld.so when it needs to load a shared library. It can be viewed as the run-time equivalent of the -L switch of ld.
ldconfig is typically run as part of the boot sequence.
The following options are recognized by ldconfig:
-c Do not scan directories listed in /etc/ld.so.conf for shared libraries.
-m Merge the result of the scan of the directories given as arguments into the existing hints file. The default action is to build the
hints file afresh.
-r Lists the current contents of ld.so.hints on the standard output. The hints file will not be modified.
-s Do not scan the built-in system directory (/usr/lib), nor any directories listed in /etc/ld.so.conf for shared libraries.
-S Do not scan the built-in system directory (/usr/lib), for shared libraries. (Directories listed in /etc/ld.so.conf are still
scanned.)
-v Switch on verbose mode.
FILES
/var/run/ld.so.hints, /etc/ld.so.conf
SEE ALSO ld(1), ld.so(1), ld.so.conf(5), link(5)HISTORY
A ldconfig utility first appeared in SunOS 4.0, it appeared in its current form in NetBSD 0.9A.
SECURITY CONSIDERATIONS
Special care must be taken when loading shared libraries into the address space of set-user-ID programs. Whenever such a program is run,
ld.so will only load shared libraries from the ld.so.hints file. In particular, the LD_LIBRARY_PATH and LD_PRELOAD is not used to search for
libraries. Thus, the role of ldconfig is dual. In addition to building a set of hints for quick lookup, it also serves to specify the
trusted collection of directories from which shared objects can be safely loaded. It is presumed that the set of directories specified to
ldconfig is under control of the system's administrator. ld.so further assists set-user-ID programs by erasing the LD_LIBRARY_PATH and
LD_PRELOAD from the environment.
