20020808: 20020808: GEMVIS and Ancient Editions of GEMPAK



Bill,

You might find someone there, maybe Ben Domenico.....I don't 
know off hand.

Several of us have been teaching the Unidata package workshops
for the past week, so there hasn't been alot of time to 
find out what others are doing.

>The underlying GEMPAK file format has not changed significantly. But,
>some additions in the newer code include machine number additions for Linux
>that older code would not be able to use if the GEMPAK file was created by a
>Linux machine for example.
>
>If the only road blocks you are having are gr_file and cfl_scnd,
>then I can suggest the following:
>
>1) gr_file was renamed dg_file in 1996:
>
>   try renaming your gr_file calls to dg_file and
>   double check the parameters being passed just in case the number/order
>   of parameters has changed.
>
>2) The cgemlib.a library includes cfl_scnd. This routine is used by the
>   current GEMPAK fl_mfls routine (probably called by the grid file open
>   routines). Your old linking probably did not include cgemlib.a, so you 
>   should add that to the list of GEMPAK libraries you are using
>   (and place after the gemlib.a reference since one pass compilers
>   will need to resolve the cfl_scnd reference after the gemlib routine
>   which calls it).
>
>If necessary, I do have the GEMPAK 5.4 distribution available....but
>hopefully for a simple converter you can update the calls to use
>the new library.
>
>Unfortunately, I will be in San Antonio next week for the
>AMS conferences on Severe Local Storms and NWP, so I won't be
>available while you are in town. But, we should be able to
>get you something to work.

>>To whom it may concern:
>>
>>Here is an interesting one for you!
>>
>>We are working with vis5d+ as both a research and teaching tool in addition
>>to the garp/nawips suite.  One of the things we are interested in doing is
>>putting a few choice Comet case studies into vis5d and vGeo (a package
>based
>>in an immersive version of vis5d).  However, the data is in gempak format
>at
>>present.  
>>
>>The Vis5D+ program has with it the source code from the old (1995) NCEP
>>program "gemvis" written by Keith Brill (He is no longer able to support it
>>and regretted that he was unable to assist).  
>>
>>The code requires access to the gemvis.o libraries and we have correctly
>>sourced them in the scripts required to compile gemvis.  However, we've
>>tried to compile it but have come across a number of roadblocks ending at
>stopping point in which the compiler is attempting to access objects
>>"gr_file_" and "cfl_scnd_".  
>>
>>Given the time that has elapsed since the writing of gemvis and the most
>>recent incarnations of the gempak suite of packages we are curious to try
>>compiling gemvis by sourcing an earlier version of Gempak.  
>>
>>Which brings us to the questions I'd like to ask:  
>>
>>1)    has the gempak format changed significantly over the years to make
>>any potential usability "gemvis" a null-and-void issue?
>>2)    Are there any old version of gempak software (c. 1995) available
>>that we could acquire for the sole purpose of compiling that code?
>>3)    Is there an option for translating gempak data to vis5d that we are
>>unaware of?
>>
>>Additionally I will be at the Foothills Lab next week (12-16 August) for a
>>conference, so if this requires direct contact I should be across the
>street
>>(My mobile number is below).

>>Cheers and Thanks!
