Syntax for setting paths to library and compiler in makefile - c

Question

I am trying to compile a program and I have to set the paths to the NETCDF inc and lib directories in the Makefile as well as set the gfortran and c compiler settings. The variables were already named as shown below, it just told me to edit the paths/options which I have tried to do. Here is what I have for my netcdf inc and lib, as well as the hdf5:
NETCDFINC = -I$(NETCDFF_INCDIR) -I$(NETCDFC_INCDIR)
NETCDFLIB = -Wl,-rpath=$(NETCDFF_LIBDIR) -L$(NETCDFF_LIBDIR) -Wl,-
rpath=$(NETCDFC_LIBDIR) -L$(NETCDFC_LIBDIR) -Wl,-rpath=$(HDF5_LIBDIR) -
L$(HDF5_LIBDIR) -lhdf5_hl -lhdf5 -lz
Note that the NETCDFLIB is on one line on my file, and the paths of the variables are correct, but the syntax may not be.
Next for the fortran and c compiler information I have the following:
FC = gfortran -m64 -g -O0 -ffixed-line-length-132 -Wunused -Wuninitialized
CC = gcc
CFLAGS = -m64 -c -g -I. -DLONG32 -DUNDERSCORE -DLITTLE -Wunused -
Wuninitialized
Finally, when I run the program I first get a bunch of warnings such as:
oban_namelist.f90:495.29:
real :: flt
1
Warning: Unused variable 'flt' declared at (1)
Followed by a bunch of undefined reference errors such as:
oban.o: In function `check':
/uufs/chpc.utah.edu/common/home/zpu-
group3/dhodges/DART/data/radar/opaws/oban.f90:1902: undefined reference to
`__netcdf_MOD_nf90_strerror'
The error shouldn't be in this oban.o function since I didn't write it. The only things I have edited in the program I listed above for the netcdf path and gfortran/c information and so I think the error lies there. This is my first question on here, so if I missed anything you need feel free to ask. What can I try?
Edit: By request, this is the entire makefile I am using. Also, I just type 'make' to compile it per the instructions in the README file.

Answer 1

The problem was solved by editing the NETCDFLIB line as follows:
I edited the NETCDFLIB line as follows and it works: NETCDFLIB = -Wl,-
rpath=$(NETCDFF_LIBDIR) -L$(NETCDFF_LIBDIR) -Wl,-rpath=$(NETCDFC_LIBDIR) -
L$(NETCDFC_LIBDIR) -lnetcdff -lnetcdf -lm -Wl,-rpath=$(HDF5_LIBDIR) -
L$(HDF5_LIBDIR) -lhdf5_hl -lhdf5 -lz
Basically I just needed to add:
-lnetcdff -lnetcdf -lm
This allowed for the compiler to get access to the libraries it needed that were originally undefined.
