The "configure" script can't find where the standard yacc tool is.  On
our Linux system (2.0.27), this is in /usr/bin/yacc, and similarly, lex
is in /usr/bin/lex.  The tools lex and yacc generate C programs from the
sources ncgen.l and ncgen.y, and are needed to build the ncgen program,
which is one of the two utility programs that comes with the netCDF
library.

If you have /usr/bin/bison, you may be able to use that instead of yacc
by specifying YACC="/usr/bin/bison".

For lex, you may be able to use /usr/bin/flex.  On our Linux system,
this is actually a symbolic link to /usr/bin/lex:

    $ cd /usr/bin; ls -l lex flex
    -rwxr-xr-x   1 root     root       134252 Aug 14  1996 flex
    lrwxrwxrwx   1 root     root            4 Feb 16 23:58 lex -> flex

The lexyacc.com file is just a command script for VMS systems and not
relevant on Linux.

If the above hints don't work, you might try building netCDF on a
different Unix system that has lex and yacc, and just copying the
generated output (files ncgenyy.c, ncgentab.c, ncgentab.h in the ncgen/
directory) to your Linux system and then executing "make" again.  Or we
could make these three files available for FTP if you can't find any
other way to generate them.
