Dear Mukesh,

this error typically shows up when the compiler you are using does not support allocations using "source", which is a feature of Fortran 2003 further updated with F2008.
Basically, you may need to update your fortran compiler to some newer versions (gfortran >= 7 works, as well as recent intel compilers).
