WAF linker error issue - build

Question

I have 2 files 1) simple1.cu 2) test.cpp. I am trying to compile and link these files using WAF.. The wscript file looks as below.
def options(opt):
opt.load('compiler_cxx')
def configure(cnf):
cnf.load('compiler_cxx')
def build(bld):
bld(
name='b1',
features='cxx',
rule='/usr/local/cuda/bin/nvcc -arch=sm_35 -dc ${SRC}',
source='simple1.cu',
target='simple1.o')
bld(
name='r1',
features='cxx',
rule='/usr/local/cuda/bin/nvcc -arch=sm_35 -dlink ${SRC} -o ${TGT} -lcudadevrt',
includes=['build'],
source='simple1.o',
target='link.o',
after='b1')
bld(
name='abc',
features='cxx',
rule='g++ -c ${SRC}',
source='test.cpp',
includes=['build'],
after='r1')
I am using the cuda separate compilation option. Now with the above file i am able to generate 3 objects files link.o simple1.o and test.o
but when i want to link them with the following..
bld(
features='cxxprogram',
rule='g++ ${SRC} -o ${TGT} -L/usr/local/cuda/lib64/ -lcudart',
includes=['build'],
source=['simple1.o','link.o','test.o'],
target='somex')
i get the following error
source not found: 'test.o' in bld(features=['cxxprogram'], idx=4, _name='somex', meths= ['create_task_macapp', 'create_task_macplist', 'process_rule', 'process_source'], prec=defaultdict(, {}), includes=['build'], source=['simple1.o', 'link.o', 'test.o']
If i link the files manually together with the command following command on the terminal it works fine (i will be able to create the executable and execute it)
g++ build/link.o build/simple1.o build/test.o -o simple -L/usr/local/cuda/lib64/ -lcudart
Please help.

Was able to solve with the following.. i thought the rule "g++ -c ${SRC}" would generate test.o but it wasnt.. Thanks to thomas who answered me in the google groups for same question.
bld(
features='cxx',
rule='${NVCC} ${CUDAFLAGS} ${CXXFLAGS} ${CPPPATH_ST:INCPATHS} ${DEFINES_ST:DEFINES} ${CXX_SRC_F} ${SRC} ${CXX_TGT_F} ${TGT}',
source='simple1.cu',
target='simple1.o',
cxxflags=['-arch=sm_35','-dc'],
includes=['build'])
bld(
features='cxx',
rule='${NVCC} ${CXXFLAGS} ${SRC} ${CXXLNK_TGT_F} ${TGT} -lcudadevrt',
includes=['build'],
source='simple1.o',
target='link.o',
cxxflags=['-arch=sm_35', '-dlink'],
stlib='cudadevrt')
bld(
features='cxx',
rule='g++ -c ${SRC} -o ${TGT}',
source='test.c',
target='test.o',
includes=['build'])
bld(
features='cxxprogram',
rule='g++ ${SRC} -o ${TGT} -L/usr/local/cuda/lib64/ -lcudart',
includes=['build'],
source=['simple1.o','link.o','test.o'],
target='somex')
