[Octave-bug-tracker] [bug #50183] tempname() returns an empty string on Solaris

[Michele]

Follow-up Comment #24, bug #50183 (project octave):

"Well, what did you do differently to get the results in comment #21? Way back
in comment #3 you ran tempname and it returned an empty string."

That is true.  That was run from my account.

"Now you've run tempname and it returns a valid temporary file name, how did
you run Octave in comment #21 vs before? Did you set the HOME and
LD_LIBRARY_PATH variables as I did? Or something else?"

I had LD_LIBRARY_PATH set to your directory, but nothing else.  IF
LD_LIBRARY_PATH is not set, Octave won't even start.  The key change appears
to involve setting HOME to the value you gave.  That got tempname to work. 
Why, I do not know.

This system grew from a plain vanilla Solaris 10 DVD.  As I discovered I
needed various tools they got added, using whatever defaults were involved. 
This resulted in stuff being spread across /usr/bin, /usr/local/bin, /opt/sfw,
/opt/csw, /export/home and perhaps more.  In addition, there are 32 bit and 64
bit versions of things in all of these.  I am not a systems engineer and this
is the first time I've tried to bring a Solaris 10 system up to date.  It's
pretty difficult to do by myself.

So I guess this looks like a configuration issue and not a bug.  You can close
it.  Thanks for your time investigating.
