No such file or directory

I am quite a beginner and so my query may sound quite trivial to u guys but plz help me out with this

when i tried to have a netcad output i changed the make file as follow:
FLAG_6 = -DNETCDF_IO
IOLIBS = -L/usr/local/lib -lnetcdf
IOINCS = -I/usr/local/include

then i had the following results:

/usr/bin/cpp -P -C -traditional -DGFORTRAN -P -C -traditional -DNETCDF_IO -DGCN -DDYE_RELEASE mod_ncdio.F > mod_ncdio.f90
gfortran -O3 -c -I/usr/local/include mod_ncdio.f90
In file mod_ncdio.f90:49

USE netcdf
1
Fatal Error: Can't open module file 'netcdf.mod' for reading at (1): No such file or directory
make: *** [mod_ncdio.o] Error 1

any help

Well.. is there a netcdf.mod file in /usr/include? Which linux distribution are you running on and how did you install netcdf libraries?

for the first part. Yes the netcdf,mod file in the /usr/include.
i did not install the netcdf libraries myself but the IT team did it for me. the Linux server is called caunton

Hmmm, is it in /usr/local/include (see the gfortran statement in your firts post) or in /usr/include?

Another story: there is a chance that a netcdf.mod file has been compiled using a fortran compiler different from that you are used to (gfortran). A compatibility issue may arise. In this case, take in mind that you can install netcdf libraries locally, under your home directory. You must not have root privileges to do that, since only your own files and directories are affected. If you need some help to do this (if it happens you need it), feel free to ask.

IOLIBS = -L/usr/lib64 -lnetcdf
IOINCS = -I/usr/include/

the required libraries are located in the above locations lib64 and include.

Then the following are the massage that i received after i compiled

i appreciate if you can guide me to start again and install Netcadf Correctly.
as i mention before i am quite new in the field. so please keep in mind

Ok. It looks like the NetCDF installed on the system have been compiled without the -fno-second-underscore option. So, if you want to install your own NetCDF for usage with gfortran, here are detailed instructions. The following commands will install NetCDF 3.6.3 under your HOME directory. I choosed version 3.6.3 instead of the more recent NetCDF 4 to avoid further complications. Unless you need the advanced functionalities of NetCDF 4, you can safely follow my choice.

1) First download the NetCDF source code (using wget from command line, or any ftp client with anonymous login)

Code:

wget ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.6.3.tar.gz

2) Unpack the archive in your HOME directory and go the the directory containing the sources

Code:

tar zxvf netcdf-3.6.3.tar.gz -C $HOME

cd $HOME/netcdf-3.6.3

3) Set the build environment

Code:

export F77=gfortran

export FC=gfortran

export FFLAGS='-fno-second-underscore  -g -O2'

export FCFLAGS='-fno-second-underscore -g -O2'

export CC=gcc

export CXX=g++

export CPP='gcc -E'

export CXXCPP='g++ -E'

4) Configure step. I suggest to install your own version of NetCDF under the same directory used for building. The installation step will create the proper bin/ lib/ and include/ subdirectories. Moreover you can enable the build of shared object

Code:

./configure --prefix=$HOME/netcdf-3.6.3 --enable-shared

5) If the step above is successful (you can check full output in config.log) do

Code:

make

6) Test the libraries before installation. Since the output of this step is very long and scrolls fast through the terminal, I suggest to save it in a file for further checking. For example, you can use tee to see the output on the terminal and save it in a file simultaneously. Then you can grep the file for words like "error", "fail", "warning", "pass".

Code:

make check 2>&1 | tee check.log

grep -i error check.log

grep -i fail check.log

grep -i warning check.log

grep -i passed check-log

7) If everything looks right you can perform the last step

Code:

make install

Now you will have your include files in $HOME/netcdf-3.6.3/include and the libraries in $HOME/netcdf-3.6.3/lib. Set the proper location in your Makefile and the trick is done (hopefully)! ;)

Thanks

i started to follow your procedure. however after the fourth step i received the following:

checking whether we are using the GNU Fortran compiler... no
checking whether gofortran accepts -g... no
checking whether we are using the GNU Fortran 77 compiler... no
checking whether gofortran accepts -g... no
configure: setting up Fortran 90
checking for Fortran flag to compile .f90 files... unknown
configure: error: Fortran could not compile .f90 files
[enxmabm@caunton netcdf-3.6.3]$

Hmmm... you sure you correctly typed the name of the fortran compiler when you set the build environment? Please, check it and try again.

Thank you all it works now.

I'm glad to hear good news! :)

Thanks, this works for gfortran compiler beautifully. Please help me building the enviroment for intel compiler.

For intel compilers

Set the build environment for intel compilers, the following way:

export CC=icc

export CXX=icpc

export CFLAGS='-O3 -xHost -ip -no-prec-div -static-intel'

export CXXFLAGS='-O3 -xHost -ip -no-prec-div -static-intel'

export F77=ifort

export FC=ifort

export F90=ifort

export FFLAGS='-O3 -xHost -ip -no-prec-div -static-intel'

export CPP='icc -E'

export CXXCPP='icpc -E'

Rest of the steps remain the same as given by colucix
