Error while compiling exciting_oxygen on Ubantu platform

Hi everyone,
I am facing problem while compiling the exciting oxygen file in ubantu. I have gone through the processes that are suggested in the discussion of Compilation error exciting_oxygen on Ubuntu, but I am still facing the error. The website says,

If compilation fails, manual editing of the file make.inc inside $EXCITINGROOT/build may be required.

If someone could guide me how to proceed ahead, I will be extremely grateful. The error and make.inc file are as follows:

CPP_ON_OPTS = -cpp -DXS -DISO -DLIBXC
F77 = $(F90)

Required for compilation of LibXC

If compiling on mac, one may need to specify the location of the openMP header file.

For example, if using Macports it may look like:

INCL = -I/opt/local/lib/gcc10/gcc/x86_64-apple-darwin19/10.2.0/finclude/

INCL =

Libaries

LIB_ARP = libarpack.a

Use native blas/lapack by default

export USE_SYS_LAPACK=true
LIB_LPK = -L./ -llapack -lblas
LIB_FFT = fftlib.a
LIB_BZINT = libbzint.a
LIBS = (LIB_ARP) (LIB_LPK) (LIB_FFT) (LIB_BZINT)

SMP and MPI compilers, flags and preprocessing variables

MPIF90 = mpif90
MPIF90_OPTS = -DMPI
MPI_LIBS =

To use Scalapack, include the preprocessing variable, provide the library path and library name

#MPIF90_OPTS = -DMPI -DSCAL
#MPI_LIBS = -L/opt/local/lib/ -lscalapack

SMPF90_OPTS = -fopenmp -DUSEOMP
SMPF77_OPTS = $(SMPF90_OPTS)
SMP_LIBS =

BUILDMPI = true
BUILDSMP = true
BUILDMPISMP = true

Any help with the compilation will be highly appreciated.
