error: variable ‘XXXX’ set but not used [-Werror=unused-but-set-variable]

error: variable ‘XXXX’ set but not used [-Werror=unused-but-set-variable]

编译的时候出现这个错误

error: variable ‘XXXX’ set but not used [-Werror=unused-but-set-variable]

2、解决办法
找到相应的Makefile文件

LOCAL_CFLAGS += -Wall -Werror

去掉上面的 -Werror，改成如下

LOCAL_CFLAGS += -Wall

或CMake(CMakeLists)

也就是把 -Werror 去掉即可！
