[ncl-install] problem with AIX precompiled NCL binaries

[Selin, Rebecca D CTR USAF AFWA 2 WXG/WEA]

Hello,

 

I am attempting to use the precompiled NCL 5.1.0 binaries for an AIX 5.3
PowerPC 6 system.  Last year, I was able to download the NCL 5.0.0
binaries for an AIX 5.3 PowerPC 5 system, and they still work fine.
However, the 5.1.0 binaries didn't work.  When testing my installation,
the following would occur:

 

nc4ex gsun01n : runs successfully, produces images

ncl gsun01n.ncl : exits before plotting anything with the error Illegal
instruction(coredump)

 

ncargex cpex08 :

NCAR Graphics Fortran  Example <cpex08>

  Copying cpexcc.f

The compile and link failed.

 

Of course, this last error makes me suspect that my libpng library is
not linking in correctly - it is not in the "normal" place.  But what is
the name of the environmental variable I need to set to define this?
I've tried PNG and LIBPNG.  And I have no idea what could be the problem
with regular NCL.

 

Thanks in advance for your help.
