g++ 无法识别选项 -wl

我正在使用GCC版本4.7.2。

我正在尝试制作以下makefile：

CC = g++
CCFLAGS = -fPIC -O3 -Wall -ffast-math -msse -msse2 -fopenmp
LINKFLAGS = -shared -Wl -fopenmp -lgomp
INPUT = im2col.cpp fastpool.cpp local_response_normalization.cpp neuron.cpp
TARGET = libcpputil.so
# If we are going to use MKL, we include additional flags
MKL_FLAGS = -D DECAF_USE_MKL
MKL_LINK_FLAGS = -lmkl_rt
all: $(INPUT)
    $(CC) -c $(CCFLAGS) $(INPUT)
    $(CC) $(LINKFLAGS) -o $(TARGET) *.o
all_mkl: $(INPUT)
    $(CC) -c $(CCFLAGS) $(MKL_FLAGS) $(INPUT)
    $(CC) $(LINKFLAGS) $(MKL_LINK_FLAGS) -o $(TARGET) *.o
speedtest_lrn: speedtest_lrn.cpp local_response_normalization.cpp
    $(CC) $(CCFLAGS) -lgomp -o speedtest_lrn speedtest_lrn.cpp local_response_normalization.cpp
clean:
    rm *.so
    rm *.o

，但G 不知何故无法识别选项-wl。这是我遇到的错误：

make -C layers/cpp/
make[1]: Entering directory `/home/ubuntu/decaf-release-master/decaf/layers/cpp'
g++ -c -fPIC -O3 -Wall -ffast-math -msse -msse2 -fopenmp im2col.cpp fastpool.cpp local_response_normalization.cpp neuron.cpp
g++ -shared -Wl -fopenmp -lgomp -o libcpputil.so *.o
g++: error: unrecognized command line option ‘-Wl’
make[1]: *** [all] Error 1
make[1]: Leaving directory `/home/ubuntu/decaf-release-master/decaf/layers/cpp'
make: *** [all] Error 2
Failed to build the C libraries; exiting

编辑：当我尝试删除" -wl"时，我得到：

ubuntu@ubuntu-VirtualBox:~/decaf-release-master$ python setup.py 
make -C layers/cpp/
make[1]: Entering directory `/home/ubuntu/decaf-release-master/decaf/layers/cpp'

   or: setup.py --help-commands
   or: setup.py cmd --help
error: no commands supplied

当我在Ubuntu 12.04和GCC 4.7.7中尝试时，它以某种方式起作用。

有人可以解释一下问题所在，我该如何解决？

谢谢吉尔。
