Test: Fortran + C + NetCDF | compiling | Mac

[Ilovecodinghaha]

Hi there,

I just installed libraries and tried to test it, following https://www2.mmm.ucar.edu/wrf/OnLineTutorial/compilation_tutorial.php step by step.

There were some errors after running each comment, but the screen displayed correctly, so can anyone help me to check if I install the libraries correctly please? If it's not correct, could you please point it out?

gfortran -c 01_fortran+c+netcdf_f.f
01_fortran+c+netcdf_f.f:5:0:
5 | INCLUDE 'netcdf.inc'
|
Fatal Error: Cannot open included file 'netcdf.inc'
compilation terminated.

gcc -c 01_fortran+c+netcdf_c.c
#return nothing

gfortran 01_fortran+c+netcdf_f.o 01_fortran+c+netcdf_c.o -L${NETCDF}/lib -lnetcdff -lnetcdf
ld: file not found: 01_fortran+c+netcdf_f.o

./a.out

Many many thanks

@HathewayWill @Ilovecodinghaha I'm seeing the same thing, I'm trying to figure it out too. Looks like netcdf.inc wasn't made

One thing that is interesting is that make check comes back without any errors or fails.

make: *** No targets specified and no makefile found.  Stop.
make: *** No rule to make target `install'.  Stop.

I think this might be the problem, netcdf fortran isn't being created.

@Ilovecodinghaha @edhartnett

There was a stray file name without the appropriate linker in the LIBS variable that caused this issue for @Ilovecodinghaha
