Jeff thanks for your help
I tried to link the compiler to the netcdf.mod file but it did not help
(before I had a link to that file in the compiling folder)
The massages I get are not from not seeing netcdf.mod
I did see people use the -I switch but did not understand where do they
point it to.
Thanks again

i an a new user to netcdf,unix,fortran so this will probably be easy to most of you but i cant get to start using the netcdf interface.

when trying to compile i get the following massages:

yair@yairsuari:~/fortran/cdfdata$ ifort create.f90 -g -o create.o

/tmp/ifortmAdSAz.o: In function `cdfcreate':/home/yair/fortran/cdfdata/create.f90:5: undefined reference to `netcdf_mp_nf90_create_' /tmp/ifortmAdSAz.o: In function `handle_err':/home/yair/fortran/cdfdata/create.f90:12: undefined reference to `netcdf_mp_nf90_strerror_'

i am using ubuntu (debian based linux) on x86 machine and intel fortran compiler 9.1

when googling around for this i saw a similar problem created when using a different compiler for your programs and for the netcdf compilation but this is not the case, i have always used intel.

please HELP

Yair: You need to use pass ifort (or any fortran compiler) the location of 'netcdf.mod', via '-I/path/to/module' and the library via '-L/path/to/netcdf/library -lnetcdf'.

-Jeff

Yair:  What about the -L flag?  It must not be finding the library then.
