The above indicates that the C compiler couldn't find the header-file
"linux/errno.h" that its own header-file "/usr/include/errno.h"
references.  This indicates a problem with the C installation (a C
implementation must be able to find all the header files that it
references).  I would show this problem to your system administrator,
complain to the vendor (RedHat), and/or reinstall the C implementation.

The problem lies with the C implementation.

> Is this a problem of my Linux version or a netcdf s/w problem ?

It's not a netCDF problem.

> Do you know of any RPM for the netcdf3.4 library that really works?

Sorry, no.

> Any suggestion to solve this problem ?
