Where do you set the LD_LIBRARY_PATH variable?

Combination View Flat View Tree View
I'm developing an application on the AXP using a newer version of GLIBC (2.9). I'm following the steps based on the article about using different glibc versions. (http://developer.cisco.com/c/document_library/get_file?folderId=1366989&name=DLFE-18401.pdf).
 
I've packaged my app with the newer glibc libraries in /usr/lib , and set my LD_LIBRARY_PATH in my post-install script. The script is as follows:
 

#!/bin/bash
# Copyright (c) 2007-2009 by Cisco Systems, Inc.
# All rights reserved.


#
# This will setup console access.  It creates a symlink to '/bin/console'
# is run anytime the user tries to connect to the console.
#
# Once the application is packaged and installed on AXP, access to the
# console can be obtained by running the following commands:
# axp# app-service HelloWorld
# axp(exec-HelloWorld)# connect console
# console-3.2# 
#


ln -s /bin/bash /bin/console
export NEXUS_VAR=testing
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib
return 1
 
When i deploy it to the AXP however and issue printenv it doesnt show the values that I set.
 
console-3.2#printenv
TERM=ansi
LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
 
My question is where and how do you set the LD_LIBRARY_PATH variable to use on the AXP?
 
Cheers.

I've also tried to test setting the LD_LIBRARY_PATH after connecting to the console of the application.
 
console-3.2#export LD_LIBRARY_PATH=/usr/lib:$LD_LIBRARY_PATH
 
However after doing that, everytime i run any application I get a "Segmentation Fault" error.
 
When I change it back to
 
console-3.2#export  LD_LIBRARY_PATH=/lib
 
all normal applications work ok (ls, ldd, etc.).
 
I've run ldd on the AXP to my webserver (lighttpd) and it shows the following.
 
console-3.2#ldd /usr/sbin/lighttpd
/usr/sbin/lighttpd: /lib/libc.so.6: version "GLIBC_2.7" not found (required by /usr/lib/libcrypto.so.0.9.8)
 
All the library dependencies (from the development machine, OpenSuse11) is copied in the AXP packages in /usr/lib .
 
I've followed the pdf to modify the startup script to load the processes from the newer glibc. My startup script is as follows:

### END INIT INFO

# Any extensions to the keywords given above should be preceeded by 
# X-VendorTag- (X-UnitedLinux- X-SuSE- for us) according to LSB.

# Notes on Required-Start/Should-Start:
# * There are two different issues that are solved by Required-Start
#    and Should-Start
# (a) Hard dependencies: This is used by the runlevel editor to determine
#     which services absolutely need to be started to make the start of
#     this service make sense. Example: nfsserver should have
#     Required-Start: $portmap
#     Also, required services are started before the dependent ones.
#     The runlevel editor will warn about such missing hard dependencies
#     and suggest enabling. During system startup, you may expect an error,
#     if the dependency is not fulfilled.
# (b) Specifying the init script ordering, not real (hard) dependencies.
#     This is needed by insserv to determine which service should be
#     started first (and at a later stage what services can be started
#     in parallel). The tag Should-Start: is used for this.
#     It tells, that if a service is available, it should be started
#     before. If not, never mind.
# * When specifying hard dependencies or ordering requirements, you can 
#   use names of services (contents of their Provides: section)
#   or pseudo names starting with a $. The following ones are available
#   according to LSB (1.1):
# $local_fs all local file systems are mounted
# (most services should need this!)
# $remote_fs all remote file systems are mounted
# (note that /usr may be remote, so
# many services should Require this!)
# $syslog system logging facility up
# $network low level networking (eth card, ...)
# $named hostname resolution available
# $netdaemons all network daemons are running
#   The $netdaemons pseudo service has been removed in LSB 1.2.
#   For now, we still offer it for backward compatibility.
#   These are new (LSB 1.2):
# $time the system time has been set correctly
# $portmap SunRPC portmapping service available
#   UnitedLinux extensions:
# $ALL indicates that a script should be inserted
# at the end
# * The services specified in the stop tags 
#   (Required-Stop/Should-Stop)
#   specify which services need to be still running when this service
#   is shut down. Often the entries there are just copies or a subset 
#   from the respective start tag.
# * Should-Start/Stop are now part of LSB as of 2.0,
#   formerly SUSE/Unitedlinux used X-UnitedLinux-Should-Start/-Stop.
#   insserv does support both variants.
# * X-UnitedLinux-Default-Enabled: yes/no is used at installation time
#   (%fillup_and_insserv macro in %post of many RPMs) to specify whether
#   a startup script should default to be enabled after installation.
#   It's not used by insserv.

If you application has dependency on any shared library then you have to make sure it's packaged along with the application if 1. It doesn't exist on AXP or
2. It's compiled using a different version of compiler than the versions used for libraries ported on AXP.
 
Ideally you application should be self contained and should be able to execute on any platform (Linux) before you port it on AXP.
 
You are setting LD_LIBRARY_PATH to /lib or /usr/lib those are standard (default) directories hence it wouldn't help. You need to point it to the directory where you have ported shared libraries and ideally it shouldn't be /lib or /usr/lib, it should be a different directory than default directory.
 
Seg fault clearly means there is a mismatch in libraries i.e. either all required libraries are not ported or your dependencies are still pointing to AXP defualt set of libraries.
 
You can also edit .bashrc on guest and that should help. or just set variable in the script which launches the application and that should also work. Below is an example
 
.bashrc file in /root in the guest side.
 
PATH='/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/java/jre1.5.0_17/bin'
export PATH
JAVA_HOME='/usr/java/jre1.5.0_17/bin'
export JAVA_HOME
 
alias jc='java -cp /usr/lib/java/localsocket.jar:/usr/lib/java/iosapi.jar:/usr/lib/java/eventapi.jar:/usr/lib/java/appreapi.jar:/usr/lib/java/xercesImpl.jar:./wsma.jar'
 
 

Hello Stan,
It looks like your end goal is to install lighttpd within an AXP application.  Is this correct?  If so, below is some information that may help you.
 
The document you reference above is applicable for AXP 1.0 and 1.1, so I would recommend a different  approach when using AXP 1.5 or later.  There are two feasable options, both have their own advantages.

Option 1:  Use the AXP Reference OS
Assuming the goal is to get lighttpd working, this is the easiest method.  The AXP Reference OS provides GLIBC v2.5-24.  In addition, AXP 1.5 provides a means to install CentOS 5.2 RPM¿s into an application.  To do so, do the following: 

1.       Download the CentOS 5 lighttpd RPM and all RPMs it depends on.  I used http://rpm.pbone.net to find these RPMs.  They are listed below.
    cyrus-sasl-lib-2.1.22-5.el5.i386.rpm
    openldap-2.3.43-3.el5.i386.rpm
    lighttpd-1.4.19-2.el5.kb.i386.rpm
    redhat-logos-4.9.99-11.el5.centos.noarch.rpm
    lua-5.1.2-1.el5.kb.i386.rpm

2.       On your workstation environment, create a directory called <source-dir>/third_party_rpms_repository, where <source-dir> is the source directory you specify to the pkg_build.sh script when building your application.  Put the above RPMs in here.

3.       Create a file called <source-dir>/third_party_rpms_repository/rpm_priority.dat.  This file provides AXP with a depdendency order when installing your RPMs.  My file looks like the following:
 
    > cat build/third_party_rpms_repository/rpm_priority.dat
    :cyrus-sasl-lib-2.1.22-5.el5.i386.rpm:1:
    :openldap-2.3.43-3.el5.i386.rpm:2:
    :lua-5.1.2-1.el5.kb.i386.rpm:3:
    :redhat-logos-4.9.99-11.el5.centos.noarch.rpm:3:
    :lighttpd-1.4.19-2.el5.kb.i386.rpm:4:
 
4.       Package your application as you normally would.  For reference, my application looks like this:
    > ls -1R
    .:
    bin 
    third_party_rpms_repository
 
    ./bin:
    post-install.sh
 
    ./third_party_rpms_repository:
    cyrus-sasl-lib-2.1.22-5.el5.i386.rpm
    lighttpd-1.4.19-2.el5.kb.i386.rpm
    lua-5.1.2-1.el5.kb.i386.rpm
    openldap-2.3.43-3.el5.i386.rpm
    redhat-logos-4.9.99-11.el5.centos.noarch.rpm
    rpm_priority.dat

5.       Install your application.

6.       Once installation is complete, you should be able to connect to the console of your application and run lighttpd.  To run using the default configuration, issue the command:

    (exec-lighttpd)# connect console
    bash-3.2# /usr/sbin/lighttpd -f /etc/lighttpd/lighttpd.conf

7.       You should now have lighttpd running inside your application.
 

Option 2:  Create an AXP User-Defined-Environment
Use this option if your application is dependent on the OpenSUSE environment.  AXP supports generating any linux environment and installing it within an application.  This option is available so you are not limited to the CentOS 5.2 environment AXP provides by default.  For more information on this, refer to the AXP developers guide.  To develop an OpenSUSE environment, you can download OpenSUSE RPM¿s and install them just as described in option 1.
