NetCDF on Mac OS

gabriel.antonius · Post by **gabriel.antonius** » Tue Apr 30, 2013 9:59 pm

Dear all,
Compiling abinit with netcdf on Mac OS has always been troublesome for me.
With abinit-7.2.2, whether I try to use the fallback or the one from macport, I get the following error:

Code: Select all

   Error: Function 'ncfile_create' at (1) has no IMPLICIT type

So it seems the header file is unuseable, despite its acceptance from the 'configure' script.

My configuration file is:

Code: Select all

   enable_mpi="yes"
   with_mpi_prefix="/opt/local/lib/openmpi"
   enable_mpi_io="no"

   with_fft_flavor="none"
   with_linalg_flavor="none"
   with_trio_flavor="netcdf"

   with_dft_flavor="libxc"
   enable_gw_dpc="yes"
   enable_64bit_flags="yes"

To use the netcdf from macport, I add the line

Code: Select all

   with_netcdf_incs="-I/opt/local/include"
   with_netcdf_libs="-L/opt/local/lib -lnetcdf -lnetcdff -lnetcdf_c++"

and I use the ports:

Code: Select all

   netcdf @4.2.1.1_1+dap+netcdf4
   netcdf-fortran @4.2_5+gcc45
   netcdf-cxx @4.2_1

My compilers are:

Code: Select all

   port:
      openmpi @1.6.3_0+gcc45

   openmpif90:
      GNU Fortran (MacPorts gcc45 4.5.4_6) 4.5.4

   openmpicc and openmpicxx:
      Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn)
      Target: x86_64-apple-darwin12.2.0
      Thread model: posix

My hardware is:

Code: Select all

    Model: MacBookPro6,2
   Processor: Intel Core i7

Does anyone have recipe to compile with netcdf on mac?

Hi Gabriel,

I think the problem is due to the fact that you are not enabling ETSF-IO
try with this patch:

call bands_ncwrite(Bands,ncf%ncid)

Note, however, that many of the routines that write netcdf files rely on the
ETSF-IO library. Hence one should always enable both ETSF-IO and NETCDF.

Hope it helps,
Matteo

Yep! Adding the line

Code: Select all

with_trio_flavor="netcdf+etsf_io"

did the trick.
Indeed, that was the default and I should have relied on that.
Many thanks!
