[ncl-install] Compiling cpex08 on a Sun Solaris 10 system

[Craig Miller]

Hi Mary

The NCL binaries that we downloaded from the EGS site were those for the 
Solaris 10 (not OPeNDAP-enabled), which were in the file 
ncl_ncarg-5.1.0.SunOS_5.10.tar.gz. Typing 'which ncargex' returns 
'/wrf/ncl/bin/ncargex', while typing 'which ncarg77' returns 'Command 
not found'. Forcing it to use the f90 compiler gets rid of all the 
errors, except the following two:

    Undefined            first referenced
     symbol                  in file
    __f95_signf                         /wrf/ncl/lib/libncarg.a(cptrev.o)
    __f95_sign                          /wrf/ncl/lib/libncarg.a(mdpint.o)
    ld: fatal: Symbol referencing errors. No output written to cpex08
    cpexcc.f:
    cpex08.f:
    Linking:


Just out of curiosity I downloaded the Solaris 10 binaries for the 
previous release of NCL (5.0.0, in the file 
ncl_ncarg-5.0.0.SunOS_5.10.tar.gz), and tried repeating everything. In 
this case it appears that the f90 compiler is invoked directly by 
ncargex with the following result:
 

    NCAR Graphics Fortran  Example <cpex08>

      Copying cpex08.f

      Copying cpexcc.f

    Compiling and linking...
    f90 -O -o cpex08 cpexcc.f cpex08.f -L/wrf/test/lib
    -L/usr/openwin/lib -lncarg -lncarg_gks -lncarg_c -lX11 -lXext
    Undefined            first referenced
     symbol                  in file
    __f95_signf                        
    /wrf/test/lib/libncarg_gks.a(gzclpo.o)
    __f90_parse_format_f77compat        /wrf/test/lib/libncarg.a(cpnumb.o)
    ld: fatal: Symbol referencing errors. No output written to cpex08
    cpexcc.f:
    cpex08.f:
    Linking:

    The compile and link failed.



Typing 'which ncargex' and 'which ncarg77' returns the same result as 
above (i.e. the directory in which ncargex resides, and 'Command not 
found' for 'which ncarg77'.

Interestingly enough, trying to compile WPS with NCAR graphics (f90 
compiler used) using the latest release of NCL (5.1.0) returns the same 
two f95 errors, as well as the additional errors you get when leaving 
the option '-lpng' out of the command

f90 -O -o cpex08 cpexcc.f cpex08.f -L/wrf/ncl/lib -L/usr/openwin/lib \
       -lncarg -lncarg_gks -lncarg_c -lX11 -lXext -lpng -lz

when trying to compile cpex08, while using the previous release (5.0.0) 
only returns the two errors encountered when executing the command 
'ncargex cpex08' with this same release.

Checking the compiler links on the machine that we are trying to run NCL 
on shows that f77 invokes the f77 compiler, while f90 and f95 invoke the 
f90 compiler.
