Setting env LD_LIBRARY_PATH

[Rafael Casero]

I'm trying to setup LD_LIBRARY_PATH env for a user, not sure how to do this.

This is what i want it to look like.

LD_LIBRARY_PATH=/app/oracle/product/9.2.0/lib32:/egate/client/bin:/egate/server/
bin:/egate/client/JRE/1.3.1_02/lib/PA_RISC:/opt/java1.3/jre/lib/PA_RISC:/opt/for
esight/HVInstream:/opt/foresight/HVInstream/java:/opt/foresight/HVInstream/bin:/
app/oracle/product/9.2.0/lib

Can some help me out. PLEASE....

You put that line in the user's .profile and use this syntax:

LD_LIBRARY_PATH=/xxx/yyy:/aaa/bbb/ccc
export LIBRARY_PATH
or
export LD_LIBRARY_PATH=/xxx/yyy:/aaa/bbb/ccc

so, your original line with the keyword 'export ' prepended will do the trick.

If the user is a csh user then you put the a similar entry in .cshrc and

setenv LD_LIBRARY PATH /xxx/yyy:/aaa/bbb/ccc

Often when LD_LIBRARY_PATH is needed SHLIB_PATH is also needed.

[A. Clay Stephenson]

OH, in case it is not obvious, .profile and/or .cshrc are located in each user's home directory and are sourced as the user logs in.

[Rafael Casero]

It would not let me put all the path's in,

It cuts the end off
:/app/oracle/product/9.2.0/lib

Would I be able to add more path's once it's created and how would I go along doing this.

I very new in this env...

Thanks..

What is "it"? You should be using a text editor such as vi and all of this is one line. Vi allows very long lines that will wrap around.

You can also do something like this:

LD_LIBRARY_PATH=/xxx/yyy/zzz:/aaa/bbc
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/mickey/mouse
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/donald/duck
export LD_LIBRARY_PATH

The idea is that you can keep adding on the the variable and then finally export it.

[Rafael Casero]

I must be doing something wrong.

1. I su as the user.
2. I set LD_LIBRARY_PATH
3. I export LD_LIBRARY_PATH

I logout and then log back in, it tells me

$ echo $LD_LIBRARY_PATH
su: LD_LIBRARY_PATH: Parameter not set.

Hi Rafael:

If you 'su' without the '-' as:

# su rafael

...then user 'rafael's profile is *not* sourced! You need to do:

# su - rafael

...to cause /home/rafael/.profile (for example) to be read (sourced).

Regards!

...JRF...

[Rafael Casero]

I use

su - rafael

And still getting the same results.

[A. Clay Stephenson]

Okay do this and post the output of each command:

1) Let's make certain that rafael's home directory (and shell) is what we think it is:

logins -o -x -l rafael #(Do this as root)

2) Now let's see if the file exists and owner/mode of the file:
ls -l /home/rafael/.profile

3) Finally, let's see what your .profile actually looks like:

cat /home/rafael/.profile

Hi,

Are putting the LD_LIBRARY_PATH in your .profile?
Do you have permission to access the specified directories?

[Rafael Casero]

Here is the outcome.

1)logins -o -x -l egate #(Do this as root)

miaux10: / =>login -o -x -l egate
Password:
Login incorrect

Wait for login retry: ..
login: egate
Password:
No utmp entry.You must exec "login" from the lowest level "sh".

Wait for login exit: ..
$

2)ls -l /home/egate/.profile

miaux10: / =>ls -l /home/egate/.profile
-r--r--r-- 1 egate egate 1794 Jun 21 15:15 /home/egate/.profile

3) cat /home/egate/.profile

miaux10: / =>cat /home/egate/.profile

You didn't execute this correctly. The command is "logins"; not "login" and you must already be logged in as root to execute it. This will look at the passwd file and tcb entries related to a specific user. I'm trying to determine home directory and shell of this user.

logins -o -x -l egate

Carefully check each of your continued lines that "\" is the very last character of such a line. Specificically, "\" is not a valid line continuation but "\" is.

The other thing to check is the sourced file oracle_setup. Make sure that there are no exit or return statements in it; if any of these are found the current process exits at that point and anything in .profile after that is never executed.

[Rafael Casero]

Sorry, thanks..

Hi Rafael:

OK, the problem is that you are trying to setup LD_LIBRARY_PATH to contain a series of pathes prepended to whatever the variable's current value represents. However, if the current value is null (undefined) you get the error " LD_LIBRARY_PATH: Parameter not set".

You could place this statement ahead of your 'export' declaration.

LD_LIBRARY_PATH=${LD_LIBRARY_PATH:=" "}

...This should achieve your purpose.

Regards!

Hi,

I perform this the same way HP-UX handles PATH and MANPATH:

- create a file /etc/LD_LIBRARY_PATH containing the requested values

- in ~/.profile or similar use:
if [ -s /etc/LD_LIBRARY_PATH ]
then
LD_LIBRARY_PATH=`cat /etc/LD_LIBRARY_PATH`
export LD_LIBRARY_PATH
fi

- I would ignore a preset envvar LD_LIBRARY_PATH from the admin point of view and handle all via this file.

You also have the same potential problem with SHLIB_PATH being undefined (as well as PATH although PATH will almost certainly have a value unless /etc/profile has been "improved").

You could do a "set +u" so that undefined variables do not cause an error but that is really considered sloppy so the better approach is test a variable before doing an assignment.

[V. Nyga]

Hi,

you have to check if the user already has an env variable.

This example is for csh and SHLIB_PATH:

if ($?SHLIB_PATH) then
setenv SHLIB_PATH ${SHLIB_PATH}:/opt/java1.4/jre/lib/PA_RISC/server:/opt/java1.4/jre/lib/PA_RISC
else
setenv SHLIB_PATH /opt/java1.4/jre/lib/PA_RISC/server:/opt/java1.4/jre/lib/PA_RISC
endif

Hi,

in what way do you login to the host?

- CDE
Check
fgrep PROFILE ~/.dtprofile
for a line like
DTSOURCEPROFILE=true


- telnet
- ssh

What is the result of
set | fgrep LIB
after login?


mfG Peter

[Rafael Casero]

I use telnet to connect.


$ set |fgrep LIB
$

Comes back to a prompt...

[Peter Nikitka]

Hi,

please send the following output:

1) echo $0 $SHELL
2) fgrep LD_LIBRARY_PATH ~/.profile
3) set -x
. ./.profile


mfG Peter

[Rafael Casero]

I got it to work...

It was a syntax error.

Thanks all for your support.. Learned a little more about env.

Thanks.
