Make all error "undefined reference to"

I'v encounter make all error I am unable to resolve

:~/caffe$ make all

collect2: error: ld returned 1 exit status

make: *** [.build_release/tools/convert_imageset.bin] Error 1

Only 2 things I changed in Makefile.config are:

# CPU-only switch (uncomment to build without GPU support).

CPU_ONLY := 1

and

# CUDA directory contains bin/ and lib/ directories that we need.

#CUDA_DIR := /usr/local/cuda

# On Ubuntu 14.04, if cuda tools are installed via

# "sudo apt-get install nvidia-cuda-toolkit" then use this instead:

CUDA_DIR := /usr

Solved by Delete Caffe and re clone and build it.
