Hi
I have a module with submodules.
A submodule uses module variables by host association.
These variables are not used in the module file.
Hence I get warnings like this:
mpi_h3_rv ! MPI halo, dim 3, right virtual
1
Warning: Unused PRIVATE module variable 'mpi_h3_rv' declared at (1) [-Wunused-value]
I guess this is because when the module file is
compiled, there is no way to know whether any
of the unused variables are used in submodules.
Even I compile both the module and the submodule file
at the same, i.e. in the same gfortran command invocation,
I get this unused warning.
I like to compile with -Wall, and I pay attention to
all warnings.
Is there a way make gfortran "see" that module
variables are used in a submodule?
Thanks
Anton
