"Word too long" error, how to solve?
 

when I run some csh script, It will show out "Word too long" error.
I have used "#!/bin/csh -xf" to trace the error, the script stop at:

setenv LD_LIBRARY_PATH $ABC_HOME/abc/cde/fgh:$LD_LIBRARY_PATH

What's the cause? How to solve it? Thanks!

BTW, My linux is Slackware 10.1.

----------
setenv LD_LIBRARY_PATH $ABC_HOME/abc/cde/fgh:$LD_LIBRARY_PATH
----------
shouldn't that be :

setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:ABC_HOME/abc/cde/fgh

without the " $ " ?

not sure though.....

Thank you! It works without the " $ " ! but the $ABC_HOME is also a variable, it could be without "$" or not?

and my another application is also show this "Word too long" error, but I couldn't modify the script. if there's any other way to waive the error?

A strange thing is that I before could run this application successfully without the "Word too long" error, but now I could not.

well... on that first command :

i think you meant to add "ABC_HOME/abc/cde/fgh " to the LD_LIBRARY_PATH ?
( so if you type " echo $LD_LIBRARY_PATH " it has " :ABC_HOME/...etc " at the end. )

...or is the whole " $ABC_HOME/abc/cde/fgh " a variable ?
and if "$ABC_HOME " is a variable, then what is "/abc/cde/fgh" ?

and on your last Q ?
maybe i'm wrong all the way , and must you set the max-length of variables to a higher value...?
( i do not know csh though... )

egag

$ABC_HOME means:

setenv ABC_HOME /tools/ABC

so "$ABC_HOME/abc/cde/fgh" must be "/tools/ABC/abc/cde/fgh"

hmmm....just tested :

------
egag@Slack21:~$ csh
%setenv ABC_HOME /tools/ABC
%echo $ABC_HOME
/tools/ABC
%setenv LD_LIBRARY_PATH /home:/home/egag
%echo $LD_LIBRARY_PATH
/home:/home/egag
%setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:$ABC_HOME/abc/cde/fgh
Bad : modifier in $ ($).
%setenv LD_LIBRARY_PATH $LD_LIBRARY_PATH:&$ABC_HOME/abc/cde/fgh
Bad : modifier in $ (&).
%setenv LD_LIBRARY_PATH $ABC_HOME/abc/cde/fgh:$LD_LIBRARY_PATH
%echo $LD_LIBRARY_PATH
/tools/ABC/abc/cde/fgh:/home:/home/egag
%
------------

what i suggested was wrong and the line from your first post is right.
but...are they really " long "

what does " echo $LD_LIBRARY_PATH " give ?

egag

hi egag,

Follow your steps, it seems no problem to csh:
setenv LD_LIBRARY_PATH $ABC_HOME/abc/cde/fgh:$LD_LIBRARY_PATH

and echo $LD_LIBRARY_PATH " gives "/tools/ABC/abc/cde/fgh:/usr/share"

-----------------------------

and WOW the script can run successfully now, I haven't changed anything, just followed your steps to have a check.

I don't know why, maybe last time it will fail again.

strange thing......
maybe " csh " just needed to see an example of how it's done ...... :)

well, just keep it in mind.
maybe you'll find the reason another time....
