Some possible compiling error and demo running error

[SuwenJunliu]

It seems that the whole program has been revised, so I reinstalled the package for inversion.

When I compile this program with OpenMPI-5.0.0, it showed the Error, etc.

mpif-sizeof.h:66:48:

Error: Fortran 2008: The symbol ‘real128’, referenced at (1), is not in the selected standard
mpif-sizeof.h:67:14:

Error: Parameter ‘real128’ at (1) has not been declared or is a variable, which does not reduce to a constant expression

The -std option in Makefile may cause it, and it seems that f2003 is incompatible with those ‘real128’ declarations in the mpi header. Maybe we could change the FFLAGS into

FFLAGS = -g -Wall -std=f2008  -pedantic -fbounds-check -O0 -Wuninitialized \
            -ffpe-trap=invalid,zero,overflow -fbacktrace \
            -fno-range-check

The second error might be a little bit tricky. When I ran the demo, it showed the error

ERROR: cannot create ./rslt/params.in.copy

That is because there is no folder named "rslt", and it might be fixed with

mkdir rslt

before running this demo.
