20041129: netcdf-3_6_0-beta6 question

Doug,

I suggest writing an executable shell-script that 1) understands the
standard UNIX syntax used in the makefile for compiling and linking
Fortran-90 code; and 2) executes the ftn95(1) utility in the appropriate
manner.  Then, configure the build procedure to use that script by

    1.  Going to the top-level source-directory.

    2.  Removing the file "config.cache" if it exists.

    3.  Setting the relevant environment variables as before.

    4.  Setting the environment variable F90 to the pathname of the
        script.

    5.  Re-executing the "configure" script.

    6.  Executing the command "make".

Regards,
Steve Emmerson

Hello Steve,

Hope you had a good Thanksgiving...

Just a quick update: I found one major problem, and that is I had *2* 
versions of the gnu fortran (g77) compiler floating around, one that I 
had downloaded explicitly for use with Windows from an individual's 
website, and another that subsequently came implicitly bundled with 
cygwin. Since both executables were accessible due to the path 
settings, I think my netcdf-3_6_0-beta6 build was getting confused. 
Anyway, long story short, I got rid of the first version I downloaded, 
redid the build with the cygwin version..and am happy to report that 
everything appears to work just fine.

However...I would still like to try to make the fortran 90 build with 
the Salford compiler I have. The test part of the make chokes, as per 
this excerpt from the test log:
---
Making `test' in directory /cygdrive/c/netcdf/netcdf-3_6_0-
beta6/src/f90

make[2]: Entering directory `/cygdrive/c/netcdf/netcdf-3_6_0-
beta6/src/f90'
ftn95 -o netcdf_test   netcdf_test.f90 netcdf.o 
typeSizes.o ../libsrc/libnetcdf.a

*** More than one source file specified



    1 ERROR [netcdf_test] - Compilation failed.

make[2]: *** [netcdf_test] Error 1
make[2]: Leaving directory `/cygdrive/c/netcdf/netcdf-3_6_0-

make[1]: Leaving directory `/cygdrive/c/netcdf/netcdf-3_6_0-beta6/src'
make: *** [f90/test] Error 2
---

This compiler does not use conventional switches, and in particular 
does not recognize the '-o' flag. It thus thinks two source files are 
being named ('netcdf_test' and 'netcdf_test.f90'), and stops dead. 
Plus, the linking is handled differently. As best I can tell based on 
the help materials supplied with the compiler, the compile line should 
look like this:

ftn95 netcdf_test.f90 /link netcdf_test /library netcdf.obj 
typeSizes.obj ../libsrc/libnetcdf.a

Note the insistance on '.obj' extensions.

So, can you tell me where and how I can modify the make files to 
execute the compile with this syntax?

Thanks and best regards,
Doug
