Hi,
I'm new to netcdf. But I'm sure I installed netcdf4 correctly on my computer,
as it passed all the test. However, when I'm trying to link my .o files, I
received a chunk of errors such as:
/usr/local/netcdf/netcdf-4.0/cxx/netcdf.cpp:172: undefined reference to
`nc_def_var'
/usr/local/lib/libnetcdf_c++.a(netcdf.o): In function `NcFile::sync()':
/usr/local/netcdf/netcdf-4.0/cxx/netcdf.cpp:275: undefined reference to
`nc_sync'
The command I used for linking is as below: (assuming .o files are ready)
#Specify the compiler
CC = g++
#Specify the compiling flags
CFLAGS = -c -I/usr/local/include
#OFLAGS = -g -o
OFLAGS = -O3 -o
LFLAGS = -L/usr/local/lib -lnetcdf_c++
OBJS = \
global_fun.o
XOBJ = ncextra.o
#=============================================================================
# Executable: xhydstmtem
#=============================================================================
ncextra : $(OBJS) $(XOBJ)
$(CC) $(OFLAGS) ncextra $(OBJS) $(XOBJ) $(LFLAGS)
#=============================================================================
Can anyone help me with this? I appreciate it.
