Unable to build test cases in arb_dirac_invert on Nvidia GPU using QUDA

[saipavan27]

I am using develop branch of this repository and I am trying to build the test cases in arb_dirac_invert
su3_fp_cl_bi
su3_fp_cl_bi_h
su3_fp_cl_bi_n
su3_fp_cl_eig
su3_fp_cg_eig

Following is the configuration I am using,
MY_CC=gcc
MY_CXX=g++
CUDA_HOME=/usr/local/cuda
QUDA_HOME=/home/all_set/build
WANTQUDA=true
WANT_FN_CG_GPU=true
WANT_FL_GPU=true
WANT_GF_GPU=true
WANT_FF_GPU=true
WANT_MIXED_PRECISION_GPU=2
PRECISION=2
MPP=false
OMP=true
WANTQIO=false
WANTQMP=false
QIOPAR=${PATH_TO_QIO}
QMPPAR=${PATH_TO_QMP}
make -j 1 su3_fp_cg_eig

Error:

make[1]: *** No rule to make target `../generic_wilson/w_source.c', needed by `w_source.o'.  Stop.
make[1]: Leaving directory `/home/all_set/milc_qcd/arb_dirac_invert'
make: *** [su3_fp_cl_bi] Error 2

I didn't find any file w_source.c , please suggest me on what to be done.

Thanks in advance :)
