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?

There is shell script which contains some variables .
These variables are used , but they have not declared in the script.
I think its a environment variable, so I want to know where these variables are set and given values
In .profile or .login..or where to c

Hi,
I am trying to set environment variable on a remote machine. I want to do it by running a shell script
Here's what I am doin

Greeting to all of you!
I've small issue related to the variable which we are setting and exporting through scripts, in one of the script there are some variable used but I am not abel to get the detail as where they are set. I tried finding the detail with the help of env but no luck.

Dear All,How can use a variable which I have exported when I am logged into one user to be used once I su to another user.something like 1.Login to Unix box as user12. export var1="TEST"3. su - user24. User the var1 value ( it should return TEST)I have checked just export does not work. any other... (1 Reply)

ld.so(8) System Manager's Manual ld.so(8)NAME
ld.so, ld-linux.so* - dynamic linker/loader
DESCRIPTION
ld.so loads the shared libraries needed by a program, prepares the program to run, and then runs it. Unless explicitly specified via the
-static option to ld during compilation, all Linux programs are incomplete and require further linking at run time.
The necessary shared libraries needed by the program are searched for in the following order
o Using the DT_RPATH dynamic section attribute of the binary if present and DT_RUNPATH attribute does not exist.
o Using the environment variable LD_LIBRARY_PATH . Except if the executable is a setuid/setgid binary, in which case it is ignored.
o Using the DT_RUNPATH dynamic section attribute of the binary if present.
o From the cache file /etc/ld.so.cache which contains a compiled list of candidate libraries previously found in the augmented library
path. If, however, the binary was linked with -z nodeflib linker option, libraries in the default library paths are skipped.
o In the default path /lib, and then /usr/lib. If the binary was linked with -z nodeflib linker option, this step is skipped.
SYNOPSIS
The dynamic linker can be run either indirectly through running some dynamically linked program or library (in which case no command line
options to the dynamic linker can be passed and the dynamic linker which is stored in the .interp section of the program is executed) or
directly by running:
/lib/ld-linux.so.* [OPTIONS] [PROGRAM [ARGUMENTS]]
COMMAND LINE OPTIONS --list List all dependencies and how they are resolved.
--verify
Verify that program is dynamically linked and this dynamic linker can handle it.
--library-path PATH
Override LD_LIBRARY_PATH environment variable setting (see below).
--ignore-rpath LIST
Ignore RPATH and RUNPATH information in object names in LIST.
ENVIRONMENT
LD_LIBRARY_PATH
A colon-separated list of directories in which to search for ELF libraries at execution-time. Similar to the PATH environment vari-
able.
LD_PRELOAD
A whitespace-separated list of additional, user-specified, ELF shared libraries to be loaded before all others. This can be used to
selectively override functions in other shared libraries. For setuid/setgid ELF binaries, only libraries in the standard search
directories that are also setuid will be loaded.
LD_TRACE_LOADED_OBJECTS
If set to non-empty string, causes the program to list its dynamic library dependencies, as if run by ldd, instead of running nor-
mally.
LD_BIND_NOW
If set to non-empty string, causes the dynamic linker to resolve all symbols at program startup instead of deferring function call
resolval to the point when they are first referenced.
LD_WARN
If set to non-empty string, warn about unresolved symbols.
LD_DEBUG
Output verbose debugging information about the dynamic linker. If set to all prints all debugging information it has, if set to
help prints a help message about which categories can be specified in this environment variable.
LD_DEBUG_OUTPUT
File where LD_DEBUG output should be fed into, default is standard output. LD_DEBUG_OUTPUT is ignored for setuid/setgid binaries.
LD_VERBOSE
If set to non-empty string, output symbol versioning information about the program if querying information about the program (ie.
either LD_TRACE_LOADED_OBJECTS has been set, or --list or --verify options have been given to the dynamic linker).
FILES
/lib/ld-linux.so.* ELF dynamic linker/loader
/etc/ld.so.cache
File containing a compiled list of directories in which to search for libraries and an ordered list of candidate libraries.
/etc/ld.so.preload
File containing a whitespace separated list of ELF shared libraries to be loaded before the program. libraries and an ordered list
of candidate libraries.
