[Wannier] error in running wannier90

[Bhubon Mech]

Sir
The make file that I have used is:
#===================
# gfortran
#===================
F90 = gfortran

#Add next two lines for parallel postw90. Choose the correct name of the
mpi f90 wrapper
#COMMS  = mpi
#MPIF90 = mpgfortran #mpif90

FCOPTS = -O3
LDOPTS =

#Next two lines are good for debugging
#FCOPTS = -Wall -Waliasing -Wsurprising -Wline-truncation -Wno-tabs
-Wno-uninitialized -Wno-unused-dummy-argument -Wno-unused
-Wno-character-truncation -O1 -g -fbacktrace
#LDOPTS = -Wall -Waliasing -Wsurprising -Wline-truncation -Wno-tabs
-Wno-uninitialized -Wno-unused-dummy-argument -Wno-unused
-Wno-character-truncation -O1 -g -fbacktrace


#=======================
# ATLAS Blas and LAPACK
#=======================
#LIBDIR = /usr/local/lib
#LIBS = -L$(LIBDIR)  -llapack -lf77blas -lcblas -latlas


#=======================
# NETLIB LAPACK and BLAS
#=======================
LIBDIR = /usr/bin/gfortran
LIBS = -L$(LIBDIR)  -llapack -lblas



After the make command in terminal i get:

when I run the wannier code I get the following error:


 ec at ec-HCL-Desktop:~/wannier90-2.0.1$ ./wannier90.x lead
 Error: Problem opening input file lead.win
Error: examine the output/error file for details

The error file is:
Wannier90: Execution started on  3Aug2016 at 20:23:32
 Exiting.......
 Error: Problem opening input file lead.win\

Sir kindly tell me where is the problem that the code is not running



With regards,
