Re: PSPP Environmental variables

[John Darrington]

A number of people seem to have been asking this question recently.

The short answer is that it's currently not possible without recompiling
pspp.  A Bug has been filed and will hopefully be fixed soon.  You can follow
the progress at http://savannah.gnu.org/bugs/?30530

Note also that when processing very large datasets, it will probably be 
worthwhile
setting the WORKSPACE parameter (see the manual for details) to some large 
figure.
This may even avoid the need for temporary files to be created in some 
instances.

     We are currently trying to get pspp up and running on one of our
     systems.  One thing we can't seem to figure out is where/how to set the
     ENV variables to get pspp to pick them up.  I have been searching the
     documentation and the internet in general for a day now, and can't seem
     to come up with an answer.
     
     We are specifically trying to set TMPDIR=/data/tmp instead of /tmp. 
     Despite the variable being exported and being echo'd, it is not picked
     up when pspp is called, and pspp defaults to /tmp.
     
     This is bad for us, as we have a 20TB partition on /data/, but only
     100GB or so on /.  This means that pspp can't be used on large files
     without erroring out with the following error message.
     
     pspp: writing to temporary file: No space left on device
     
     When using pspp, I can see that it is writing to /tmp, not /data/tmp
     when it is running:
     
     pspp      15778     testuser    6u      REG                8,1  
     71942660096    7700489 /tmp/tmpftWxyZS (deleted)
