当您启动利用dirtycow错误时，弹出目录名命令未找到

Question

我想在Linux上启动一个exploitdunkcow。当我运行make root命令时，出现错误：

/home/olegratnikov/android-ndk-r18b/build/ndk-build: line 40: dirname: command not found
/home/olegratnikov/android-ndk-r18b/build/ndk-build: line 122: uname: command not found
ERROR: Unknown host operating system: 
Makefile:8: recipe execution error for "build" target
make: *** [build] Mistake 1

Makefile：

ARCH := $(shell adb shell getprop ro.product.cpu.abi)
SDK_VERSION := $(shell adb shell getprop ro.build.version.sdk)
PATH :=/home/olegratnikov/android-ndk-r18b/build
all: build

build:
    ndk-build NDK_PROJECT_PATH=$(PATH) APP_BUILD_SCRIPT=./Android.mk APP_ABI=$(ARCH) APP_PLATFORM=android-$(SDK_VERSION)



 push: build
        adb push libs/$(ARCH)/dirtycow /data/local/tmp/dcow
        adb shell 'chmod 777 /data/local/tmp/dcow'
test: push
    adb push test.sh /data/local/tmp/test.sh
