[ncl-install] problem with AIX precompiled NCL binaries

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

May,

Sorry, I did indeed mean "ng4ex".  Yes, it makes no sense to me either why "ng4ex gsun01n.ncl" would work and "ncl gsun01n.ncl" would not.

When I tried running "ng4ex xy01n -clean" I got the "Illegal instruction (core dumped)" error again.

Interestingly, I am able to get both "ng4ex ap01n" and "ncl ap01n.ncl" to work.

Thanks again.

Becky,

I'm not sure I understand the above.  By "nc4ex" did you mean "ng4ex"?
If "ng4ex gsun01n.ncl" works, then I don't understand why "ncl
gsun01n.ncl" wouldn't work, since "ng4ex" is doing this internally.

Are you able to run:

    ng4ex xy01n -clean

?

For this problem, it looks like you may be using an old "ncargf77",
because the new one should be including "-lpng -lz" on the compile
line.

You can try the compilation yourself with:

   ncargex cpex08 -n
   ncargf77 cpex08.c cpexcc.c -lpng -lz
   ./a.out

If you don't get any errors, then you should now have a "gmeta"
file which you can view with "ctrans":

    ctrans -d X11 gmeta
