Hi,

I'm on a Debian unstable system, with:

libnetcdf-dev (Version: 1:4.1.1-5)
libnetcdf6 (Version: 1:4.1.1-5)
netcdf-bin (Version: 1:4.1.1-5)

and I'm trying to install OTPSnc
(http://volkov.oce.orst.edu/tides/otps.html) package.  Following the
README instructions, I modified the makefile to read:

---<--------------------cut here---------------start------------------->---
ARCH = $(shell uname -s)
ifeq ($(ARCH),SunOS)
 FC = f90
 NCLIB = /home/server/local/lib.solaris2x
 NCINCLUDE = /usr/local/include
endif
ifeq ($(ARCH),Linux)
 FC = gfortran
 NCLIB = /usr/lib
 NCINCLUDE = /usr/include
 NCLIBS= -lnetcdf
endif

predict_tide: predict_tide.f subs.f constit.h
        $(FC) -o predict_tide predict_tide.f subs.f -L$(NCLIB) $(NCLIBS) 
-I$(NCINCLUDE) 
        #rm *.o
extract_HC:  extract_HC.f subs.f
        $(FC) -o extract_HC extract_HC.f subs.f -L$(NCLIB) $(NCLIBS) 
-I$(NCINCLUDE)
        #rm *.o
---<--------------------cut here---------------end--------------------->---

but compilation fails for the two targets, even though I've supplied
what I think are the proper NCLIB and NCINCLUDE variables.  Here's the
output for 'make extract_HC':

---<--------------------cut here---------------start------------------->---

The program extract_HC.f does have a line near the top:

include 'netcdf.inc'

which is certainly in /usr/include/netcdf.inc, so I'm surprised the
netcdf functions are not being found.  Any suggestions would be
appreciated.

Cheers,
