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

[王梓元]

Dear Dr Alan Brammer

In my school cluster, I load GCC/4.7.2 and ncl/6.3.0, then I rerun WRAPIT of external binary.so, It worked successfully, and thank you very much for help


Yours

I don’t think the operator is the problem.


Always start from the first error. 
warning:An error occurred loading the external file $NCL4GC/fortran/binary.so, file not loaded
libifport.so.5: cannot open shared object file: No such file or directory


warning:error at line 23 in file $NCL4GC/file_io/read_bpch.ncl


Did you rerun WRAPIT with the new NCL install.  If you changed your gcc installation you might need to recompile the shared object.  


This would be best in a new email specifically about the loading of the shared object in your script.   The :: operator is not the problem though it’s the initial external command that is failing.

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

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 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
