Compiling Fortran netCDF programs on Ubuntu

Question

Ok, newb question here.

I\'m trying to compile simple_xy_wr.f90 -- a netCDF example program -- using gfortran on Ubuntu, and I must be doing something pretty silly;

Answer 1

In Ubuntu 12.10, the order of the libraries is the trick (as Hristo suggested):

angelv@palas:~$ gfortran  -o xy -I/usr/include/ -L/usr/lib/  -lnetcdf -lnetcdff simple_xy_wr.f90
/tmp/ccj95anF.o: In function `check.1847':
simple_xy_wr.f90:(.text+0x72): undefined reference to `__netcdf_MOD_nf90_strerror'

angelv@palas:~$ gfortran  -o xy -I/usr/include/ simple_xy_wr.f90 -L/usr/lib/  -lnetcdf -lnetcdff
