我想为

Android设备编译pref,我在指南

the guide上做了这个.我设置NDK环境使用Android NDK r9

export NDK_TOOLCHAIN=${NDK}/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-

export NDK_SYSROOT=${NDK}/platforms/android-9/arch-arm

我用工具运行make

make ARCH=arm CROSS_COMPILE=${NDK_TOOLCHAIN} CFLAGS="--sysroot=${NDK_SYSROOT}"

我收到错误,你能帮帮我吗？
