This looks like a problem with the way gcc is being invoked or the system
include files rather than netCDF.  NetCDF has been successfully built on
LINUX, and we've added the information below on what's required to our
Frequently Asked Questions list at

 16. How can I build netCDF under Linux?

     Frank Dzaak (address@hidden) reports the following changes to the
     current version are sufficient: 

     1. Before running configure, set OS=linux in your environment or in
        Makefile.in.

     2. For a FORTRAN interface, copy fortran/sunos.m4 to fortran/linux.m4
        and in that file change the name Sun to Linux with

                     define(`M4__SYSTEM', Linux)

     3. Copy the definition of the "STREQ" macro from ncgen/ncgenyy.c to
        ncgen/ncgentab.c.

     These are reported to work for Linux kernel 1.0.9, CC=gcc(2.5.8),
     F77=f2c, LEX=flex, YACC=bison. 

None of the changes above would seem to be related to the errors you are
seeing from compiling array.c.  I'm also puzzled why gcc is being invoked
with "-Dconst=", since it can handle const declarations.  Please make sure
you start with a clean distribution (use "make distclean" if necessary)
before you run the "configure" script.  Otherwise, if you are using the
Makefiles left over from building netCDF on Suns, for example, the Makefiles
generated by "configure" will be wrong.

Currently we don't have access to a LINUX platform for porting, so we can't
build or test the netCDF library on LINUX.  We depend on LINUX users in the
community to help us with that and other platforms we don't have, by testing
each new release and giving us any changes that need to be made.

If you still can't build netCDF on LINUX, you might want to post a query to
the address@hidden mailing list of about 400 netCDF users, to
see if anyone else who has built it on LINUX knows what the problem is.
