Re: [photran] using netcdf libraries
Hi, your line misses actual library:
gfortran -L"E:\Programming_tools\eclipse\readNETCDF_test\netcdf40\lib" -o"readNETCDF_test"  ./nc4_simple_xy_wr.o

should be

gfortran -L"E:\Programming_tools\eclipse\readNETCDF_test\netcdf40\lib" -lnetcdf -o"readNETCDF_test"  ./nc4_simple_xy_wr.o


are you using makefile project? You could just give the path to the linker without -L:
gfortran "E:\Programming_tools\eclipse\readNETCDF_test\netcdf40\lib\libnetcdf.a" -o"readNETCDF_test"  ./nc4_simple_xy_wr.o


this worked for me, example of my old make file

# Change this line if you are using a different Fortran compiler
FORTRAN_COMPILER = pgf90

LIBS = lib/losub.a -lcurl -lhdf5_hl -lhdf5 lib/netcdf/lib/libnetcdf.a

all: src/module/*.f90 src/*.f90
    $(FORTRAN_COMPILER) -O2 -g -i8 -r8 -byteswapio -Mbounds\
        -o bin/ReadCCC.exe \
        src/module/*.f90 src/*.f90 $(LIBS)

clean:
    rm -f bin/ReadCCC *.mod *.exe


Cheers

Dear All,

 

(Before anything, great Eclipse, great Photran! – Thanks to all who make this possible!)

 

I program for some years now as a need, but I’m not a “real” programmer so,  sorry for some “less correct nomenclature”.

I’ve been trying for days to use NETCDF libraries with my Eclipse Helios and Photran 6 on Windows 7 (32Bit). And I couldn’t find a post on this. So here it goes:

 

Intro: NETDCF is a binary format and the name stands for NETwork Common Data Format and is widely use for scientific data transfer.

Info on NETCDF is available at http://www.unidata.ucar.edu/software/netcdf/

 

At this website they release binaries and source code to use.

At this stage I´m  trying to set up the use of the libraries with their own a sample fortran code:

Available here: http://www.oifii.org/ns-org/nsd/ar/netcdf-4.0/examples/F90/nc4_simple_xy_wr.f90

 

I downloaded the version 4.0 (binary-netcdf-4.0_gfortran_gfortran_c++.tar.gz - Binary distribution of netcdf-4.0 on linux_2.6-x86_64) here:

http://www.unidata.ucar.edu/downloads/netcdf/netcdf-4_0/index.jsp

 

I downloaded the linux version, as I assume cygwin will deal with it as it deals with the Photran…

 

this comes with a structure of 4 folders as:

bin

include

lib

share

 

which I added to a subfolder called netcdf40 of my Photran Project.

 

After reading the “Compiling and Linking with the NetCDF Library” intructions  (http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-f90/Compiling-and-Linking-with-the-NetCDF-Library.html#Compiling-and-Linking-with-the-NetCDF-Library )

 

I then went to my Photran project properties and added the include path and the lib path as

 

Fortran Build ->Directories -> Include paths: "${workspace_loc:/${ProjName}/netcdf40/include}"

GNU Fortran Linker ->Libraries -> Include paths: "${workspace_loc:/${ProjName}/netcdf40/lib}"

 

 

When compiling, it seems it grabs the include path, but it does not recognizes the functions/routines in the library. Here’s the compiling output:

 

**** Build of configuration Debug for project readNETCDF_test ****

 

make all

Building target: readNETCDF_test

Invoking: GNU Fortran Linker

gfortran -L"E:\Programming_tools\eclipse\readNETCDF_test\netcdf40\lib" -o"readNETCDF_test"  ./nc4_simple_xy_wr.o  

cygwin warning:

  MS-DOS style path detected: E:\Programming_tools\eclipse\readNETCDF_test\Debug

  Preferred POSIX equivalent is: /cygdrive/e/Programming_tools/eclipse/readNETCDF_test/Debug

  CYGWIN environment variable option "nodosfilewarning" turns off this warning.

  Consult the user's guide for more details about POSIX paths:

    http://cygwin.com/cygwin-ug-net/using.html#using-pathnames

collect2: ld returned 1 exit status

make: *** [readNETCDF_test] Error 1

 

I also tried other different ways to put the –L in the miscellaneous section (and removing from Libraries) but the problem persists.

 

What am I doing wrong?

Any help would be appreciated.
