功能:通过shell(sh）编译将类型传给makefile,然后makefile将参数传到c.

1，编译脚本

test.sh

#!/bin/bashfunction print()echo "type:        opu"echo "             odu"echo "             otu"echo "Error Input: "  
}case $1 in"odu")echo "odu"export DEVICE_TYPE=ODU./test_make  $DEVICE_TYPEecho "end";;"opu")echo "opu"export DEVICE_TYPE=OPU./test_make  $DEVICE_TYPEecho "end";;"otu")echo "otu"export DEVICE_TYPE=OTU./test_make  $DEVICE_TYPEecho "end";;*)printexit 1
esac

2.test_make 

DEVICE_TYPE="$1"
echo $1
make -f Makefile clean
make DEVICE_TYPE=$DEVICE_TYPE

测试：直接自己运行test_make测试

使用make clean 和 make -f Makefile clean 有什么区别！ 

 3 Makefile

#!/bin/b
