[DFTB-Plus-User] DFTB+ 19.1 installation

[Anshu Gaur]

Hello,

I am facing problem while installing 19.1 version (with ELSI and PEXSI). 
ELSI library alsong with PEXSI is installed and the links are provided 
in 'make.config'. The error(s) I get are partly replicated below:

/---------------------------------

elsisolver.o: In function `dftbp_elsisolver_MP_telsisolver_final_':
elsisolver.f90:(.text+0x18): undefined reference to 
`elsi_setup_MP_elsi_finalize_'

`elsi_rw_MP_elsi_write_mat_real_'

recipe for target 'dftb+' failed
make[1]: *** [dftb+] Error 1
--------------------/

Any particular reason for such error. Specifically, why is 
'elsi_setup_MP_' or 'elsi_rw_MP_' added in front of objects?

Any help is much appreciated and eagerly waiting to try version 19.1 
(have been using 18.2 for past one year or so).
