Octave 6.2.0 + MKL (intel-oneapi-mkl 2021)

The following is the configure option to include MKL in Octave.

MKL is installed via Spack, and the version is intel-oneapi-mkl@2021.2.0

CPPFLAGS=" -I${MKLROOT}/include -I${MKLROOT}/include/fftw" \

LDFLAGS=" -L${MKLROOT}/lib/intel64" \

CFLAGS="-O3 -fPIC -DM_PI=3.1415926535897932384  -I${MKLROOT}/include -I${MKLROOT}/include/fftw" \

F77="gfortran" \

../octave-6.2.0/configure --prefix=/path/to/install \

--with-blas="-lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -lgomp -lpthread" \

--with-lapack="-lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -lgomp -lpthread" \

--with-fftw3="-lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -lgomp -lpthread -lm" \

--with-fftw3f="-lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -lgomp -lpthread -lm" \

--disable-java --enable-static

It seems that using intel compiler with mkl is problematic.
