Chris,

>I am writing to you for help with the net cdf msdos materials I downloaded
>from unidata. I copied the netcdf.lib into my Microsoft FORTRAN v5.1 
>library folder, the netcdf.inc into the include folder, and I dug up a 
>Microsoft C Llibc7.lib and copied it into the library folder.

The MSDOS version of netCDF that is available by anonymous FTP was built
using Microsof Fortran v5.1 and Microsoft C v6.0.  This is pointed out
at the end of pub/netcdf/msdos/README:

"NOTE: These binaries and compiled libraries have been tested with MSDOS 5.0.
They were created using Microsoft C 6.0 and Microsoft Fortran 5.1.  Versions
of Fortran before 5.0 are not compatible with the FSLEN.OBJ function, so the
FORTRAN interface will not work with older version of FORTRAN."

We hinted that there was needed changes for Microsoft C++/C7.0 in:

"Also see the extensive notes on changes recommended to netCDF version 2.3 to
build the library and programs using Microsoft's C++/7.0 compiler without a
coprocessor in the file pub/netcdf/contrib/msoft-7.0.

William A. Spencer supplied some information on how to build netCDF 2.3
using Microsoft C++/C7.0.  His comments can be found in
pub/netcdf/contrib/msoft-7.0.  You might do better to grab the source
for 2.3(.2) and apply the mods that he suggests before proceeding.
We have no way of testing our your problem here since we do not have the

Where is the specification of the Fortran library on the link line?  An
example link line taken from the netcdf23/fortran/msoft.mk file in the
netCDF distribution for MSDOS (embodied in pub/netcdf/msdos/NETCDF.ZIP) is
given by:

$(GOAL) in this case would be the executable to be produced.  The link

Again, your link line does not include a reference to the Fortran library.
In addition, it may be that your C library wasn't built to include Fortran
compatibility.  On top of all of that, you are using a compiler combination
that we didn't use to build the libraries, and we have been told by
a user that Microsoft C++/C7.0 requires significant changes.

Can you dig up Microsoft C 6.0 somewhere?

See above.

If you can find the Microsoft C 6.0 compiler, you should be able to
produce code using the netCDF library provided.
