[ncl-talk] 答复: Can't work with reassign command ':=', and '::' call fortran command

[Ziyuan Wang]

Hi Alan

 

Now I installed ncl/6.30 with gcc/4.7.2, and run that scripts again, but now it see can’t read operator “::”, as error reported (attached 2.error)

fatal:syntax error: line 119 in file read_bpch.ncl before or near : 

    BIN:

-------^

fatal:error in statement

 

and line 119 in ncl is “; Call a Fortran routine to parse bytes into separate variables

BIN::bpch_hdr1( bytes, c_modelname, lon, lat, halfpolar, center180 )” (attached read_bpch.ncl)

Thank you

 

Ziyuan

That operator was introduced in 6.2.1 it won’t work in versions prior to that.  6.2.1 is roughly 4 years old.  There will be lots of missing functionality if you’re stuck on < 6.1. 

 

To work around, you can replace all := with = and where needed add a delete(fti) or the appropriate variable on the line before. 

 

delete() will throw an error if the variable doesn’t exist though so you’ll need to go through and decide for each instance.  

 

You might want to email ncl-install at ucar.edu <mailto:ncl-install at ucar.edu>  about your installation problems (or one of the devs might help you out in here).

Dear all Users:

I want to run a ncl scripts written by geos-chem model to read bpch files (read_bpch.ncl attached).

1.When I use ncl/6.1.0 or 6.0.0, it can't work with the re-assign operator :=, as error

fatal:syntax error: line 96 in file $NCL4GC/file_io/read_bpch.ncl before or near : 

  fti         :

--------------^

line 96 in bpch.ncl is "fti         := get_string_from_bpch( inFile, R, 40 ) " (attached 1.error)

2. When I use ncl/6.3.0, in our school cluster there's no intel/12.1.5, so I have to load gcc/4.7.2. Then it can't read fortran command. And for model compiling I also need intel fortran.

fatal:syntax error: line 119 in file $NCL4GC/file_io/read_bpch.ncl before or near : 

    BIN:

-------^

Line 129 in bpch.ncl is " BIN::bpch_hdr1( bytes, c_modelname, lon, lat, halfpolar, center180 )" (Attached 2.error)

3.So I'm wondering how can I change read_bpch.ncl code, to make the ':=' work in ncl/6.1.0

Thank you everyone
