Defined "Undefined variable"

neoserdes · 02-04-2012, 11:21 AM

Hi,

I got a really weird issue of environment variable.

When I execute the software, it complained about one variable is not defined. However, when I echo this variable right after, it appears defined well.

What is going wrong there? I'm using rhel 5.6 without subscription.

Regards,
Neo

Warning: environment variable SW_SX_COMMON is not defined.

%echo $SW_SX_COMMON
/eda/tool

is the variable exported? like by running

Code:

export SW_SX_COMMON

before you run the program

oh. In that case, try

Code:

setenv SW_SX_COMMON "/eda/tool"

I did put this in .cshrc and also executed on the command line. However, it is still the same.

Code:

setenv SW_SX_COMMON "/eda/sx_a2008_03-SP1"

PHP Code:


			
 %echo $SW_SX_COMMON

/eda/tools

I'm confused. Thanks.

That's strange. What is the software you are trying to run?

neoserdes · 02-04-2012, 02:26 PM

It is an EDA software. Sandword waveviewer.

Anyway, it doesn't stop me from using it. Let go so far.

Sounds like its not being exported to appear in any sub-shells created during the run of the SW.
Defining the var means it only appears in the current shell.
Don't know the syntax for exporting a var in the *csh shells, but I'm sure you do

I already used

Code:

setenv XXX "YYY"

But it doesn't seem to pass down?
