<div>It looks like both of them have not linked with 'libcairo'. Do you think I

<div>OK, that's interesting. Ultimately it would be the cairographics
(libcairo) that's responsible for drawing to the "ps" workstation. Fixing the
problem is likely to be rather tricky:</div>
<div><br></div>
<div>i) its hard to see how a simple kernel upgrade could have affected
anything; was it perhaps a complete Linux OS upgrade (which would likely
install newer versions of libraries and other software)?<br></div>
<div>ii) is your NCL binary dynamically linked against cairo? try:</div>
<div> ldd `which ncl`</div>
<div>and look to see *if* cairo is showing up in the list, and note where it
is coming from.</div>
<div>iii) its also hard to imagine the cairo library would be built without PS
support -- its possible, but one has to be very deliberate. But this is all
I can think of that might be the source of the problem. I should think
NCL would give you a meaningful error message, but...? If cairo is
dynamically liked, you could possibly build it yourself (it requires building
pixman too), put it is a directory in your own workspace, and setting this
environment variable to force the system to look at that location first:</div>
<div><br></div>
<div> export LD_LIBRARY_PATH=/....your-cairo-dir:$LD_LIBRARY_PATH</div>
<div><br></div>
<div>That seems like a lot of work, and I'm not certain it would fix the
problem (maybe your sysadmin could do this)</div>
<div><br></div>
<div>If you can live with the oldps driver, you can set this environment
variable that will override the "ps" workstation with "oldps". Note that oldps
does not support translucent colors and is possibly limited to 256 colors (I
can't recall)<br></div>
<div><br></div>
<div> export NCARG_OLD_PS=true</div>
<div><br></div>
<div>Hope that helps and good luck!</div>

<div> Thanks for your kindly answer.</div>
<div> I have tried with "oldps". It works well. In
this case, how should I fix my "ps" case's problem, please? Do you know
which library should lead to this problem?</div>

<div>Hi,</div>
<div><br></div>
<div>I do not have a good explanation as to why that is happening. But I
wonder if you would try an experiment with me -- in the gsn_open_wks()
statement, try using "oldps" instead of just "ps", and let me know
happens. "oldps" (an unfortunate name that I'm responsible for)
refers to the legacy postscript driver, vs. the current default drivers
based upon cairographics. Postscript support is optional in
cairographics, but one has to go to lengths to disable it. I can't think
of any other explanation however...</div>

<div>Dear all,</div>
<div> </div>
<div> I am trying to use NCL
V6.5.0 on the computer nodes of our super-computer. It can work when I
set the figure type as "png" or "pdf". But it can not work with
"ps". It can output a zero size file named "<a href="http://aaa.ps" target="_blank">aaa.ps</a>", and without any error message.
However, the same script can work well on the login node with any figure
type, "ps", "png", "pdf". </div>
<div> Initially, it also can work
well with "ps" type on the computer node in May. It is side that
the super-computer administrator had upgraded the kernel of Linux system
in June. </div>
<div></div>
<div> Anybody can give me any
suggestion how to fix my problem? Or which software maybe changed when
upgrading the Linux system, then affecting the generation of the
figure of "ps" type?</div>
<div> </div>
<div> Thanks and
regards. </div><u></u>
