大家好，又见面了，我是你们的朋友全栈君。

为啥要移植lrzsz

本文中的lrzsz代码点击此处获取
Hikey开发板有两类USB口，两组USB-TypeA母口作为Host，可以接键盘、鼠标。另一组mini-USB母口，作为devices，可以接到电脑上调试。但目前这两种接口无法同时使用，即通过键盘鼠标操作时不能使用ADB。
虽然可以通过minicom或者putty之类的工具连接串口查看LOG、执行命令。但Android系统中缺少通过串口传输文件的工具，有文件传输需求的时候还需要插上ADB口，通过adb push/pull操作，不是太方便。

通过busybox的rx命令虽然可以接收文件，但无法将系统中的文件传输到主机上。而且rx只支持xmodem协议。一些新的工具如Xshell只能支持Zmodem协议。
lrzsz能够同时支持xmodem、ymodem以及zmodem协议，具备发送接收功能，能满足我们的需要。

交叉编译lrzsz

交叉编译分为以下几步：

准备交叉编译链。

这里面使用的是arm-linux-gnueabihf-4.9。可以到Linaro的主页下载。将下载到的文件解压缩到/opt/目录，设置好环境变量。

[david@opt]$ cd arm-linux-gnueabihf-4.9/bin/
[david@bin]$ export PATH=`pwd`:$PATH
[david@bin]$ arm-linux-gnueabihf-gcc --version

2下载lrzsz源码
从官方主页下载lrzsz软件包 lrzsz-0.12.20.tar.gz 。解压缩。

[david@Code]$ tar -zxvf lrzsz-0.12.20.tar.gz

我们很容易将其翻译为如下的Android.mk

LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS)
LOCAL_SRC_FILES := \     lib/long-options.c \     lib/xstrtol.c \     lib/xstrtoul.c \     lib/error.c 
LOCAL_MODULE := libzmodem
LOCAL_MODULE_TAGS := optional

LOCAL_C_INCLUDES := $(LOCAL_PATH) LOCAL_CFLAGS := -DHAVE_CONFIG_H include $(BUILD_STATIC_LIBRARY)

include $(CLEAR_VARS) LOCAL_SRC_FILES := \  src/lrz.c \  src/timing.c \  src/zperr.c \  src/zreadline.c \  src/crctab.c \  src/rbsb.c \  src/zm.c \  src/protname.c \  src/tcp.c \  src/lsyslog.c \  src/canit.c LOCAL_MODULE := lrz LOCAL_MODULE_TAGS := optional tests LOCAL_C_INCLUDES := $(LOCAL_PATH) \     $(LOCAL_PATH)/src \  $(LOCAL_PATH)/lib \     $(LOCAL_PATH)/intl LOCAL_STATIC_LIBRARIES := libc \  libzmodem \  libnsl LOCAL_CFLAGS := -DNFGVMIN -DHAVE_CONFIG_H -DLOCALEDIR=\"/system/etc/locale/\" LOCAL_FORCE_STATIC_EXECUTABLE := true include $(BUILD_EXECUTABLE)

但编译时出现如下的错误，原因是Android系统中没有libnsl库，所以修改config.h，将

#define HAVE_LIBNSL 1

修改为：

#define HAVE_LIBNSL 0

同时删除 Android.mk 中所有的libnsl，即可通过。
最终的Android.mk

adb root
adb remount
adb push lrz /system/bin/lrz
adb push lsz /system/bin/lsz
adb shell chmod 777 /system/bin/lrz
