[ncl-install] Erratic behavior on Macbook Pro with Ubuntu

[Mary Haley]

Hi Sebastian,

I don't have access to a Debian 6.0 system any more, since we upgraded
them.  I do have a Debian 7.9 system, and already had "fix" built there.

The fix is simply a new "ncl" executable.  To get the file, which I've
renamed to "ncl630.fix.debian78"

     wget ftp.ucar.edu:/pub/scd/haley/ncl630.fix.debian78

or:

     ftp ftp.ucar.edu
     <log in as "anonymous">
     <Use email address as password>
     cd /pub/scd/haley
     get ncl630.fix.debian78
     quit


Once you have the file, move it to $NCARG_ROOT/bin and make sure it is
executable. You can call it whatever you like. I'll use "ncl.fix" as an
example:

    chmod gou+x ncl630.fix.debian78
     mv ncl630.fix.debian78 $NCARG_ROOT/bin/ncl.fix

Now you can use this new "ncl.fix" executable instead of the one already
installed on your system:

    ncl.fix  your_script.ncl

One thing different you will notice about the behavior when you are drawing
graphics to an X11 window:  a blank screen will pop up, and then the whole
plot will show up at once.

If you are comfortable that this executable works, you can replace your old
ncl executable with this new one. You should first make a copy of your old
one just in case, because this one still works for other output formats,
like PNG, PS, PDF, etc.

   cd $NCARG_ROOT/bin

   mv ncl ncl.old

   mv ncl.fix ncl

This should should do it.  Please let me know if you have any problems.

--Mary
