/**************************************************************************** *                 I.MX6 Android busybox 從哪裡產生的 * 說明： *     一直在Android中找busybox的原始碼在哪裡，在external檔案夾下有一份busybox * 原始碼，但是沒有Android.mk，以為應該是將Android.mk檔案放在了別的地方，結果 * 找出來是別的地方放了一份編譯好的busybox可執行檔。 * *                                          2016-8-20 深圳 南山平山村 曾劍鋒 ***************************************************************************/一、參考文檔：    1. 怎樣判斷兩個bin檔案，是不是同一個檔案。。兩個bin檔案，名字不同。不知道內容是不是一樣的。        http://zhidao.baidu.com/question/486446127.html    2. linux md5sum 的用法（轉）        http://www.cnblogs.com/chenwenbiao/archive/2012/07/10/2585507.html二、原因：    在~/myandroid/external/busybox目錄下並沒有找到對應Android.mk檔案，說明busybox並不是從這份原始碼中產生出來的，而是從別的地方產生的，於是得重新找busybox真是的出處。三、cat ~/myandroid/device/fsl-proprietary/test/Android.mk    LOCAL_PATH := $(call my-dir)        include $(CLEAR_VARS)    LOCAL_MODULE := mxc_ipudev_test    LOCAL_MODULE_TAGS := eng    LOCAL_MODULE_PATH := $(TARGET_OUT)/bin    LOCAL_MODULE_CLASS := EXECUTABLES    LOCAL_SRC_FILES :=  bin/mxc_ipudev_test    include $(BUILD_PREBUILT)        include $(CLEAR_VARS)    LOCAL_MODULE := mxc_vpu_test    LOCAL_MODULE_TAGS := eng    LOCAL_MODULE_PATH := $(TARGET_OUT)/bin    LOCAL_MODULE_CLASS := EXECUTABLES    LOCAL_SRC_FILES :=  bin/mxc_vpu_test    include $(BUILD_PREBUILT)        include $(CLEAR_VARS)    LOCAL_MODULE := busybox    LOCAL_MODULE_TAGS := optional    LOCAL_MODULE_PATH := $(TARGET_OUT)/bin    LOCAL_MODULE_CLASS := EXECUTABLES    LOCAL_SRC_FILES :=  bin/busybox    include $(BUILD_PREBUILT)四、檢查兩個busybox是否是同一個busybox：    [email protected]:~/myandroid/device/fsl-proprietary/test/bin$ stat busybox       File: `busybox‘      Size: 1634104       Blocks: 3192       IO Block: 4096   regular file    Device: 801h/2049d    Inode: 1313488     Links: 1    Access: (0775/-rwxrwxr-x)  Uid: ( 1000/    myzr)   Gid: ( 1000/    myzr)    Access: 2016-08-20 11:09:25.828600234 +0800    Modify: 2014-04-11 14:10:13.000000000 +0800    Change: 2015-04-02 14:43:27.691788786 +0800     Birth: -    [email protected]:~/myandroid/device/fsl-proprietary/test/bin$ stat /home/myzr/myandroid/out/target/product/sabresd_6dq/obj/EXECUTABLES/busybox_intermediates/busybox      File: `/home/myzr/myandroid/out/target/product/sabresd_6dq/obj/EXECUTABLES/busybox_intermediates/busybox‘      Size: 1634104       Blocks: 3192       IO Block: 4096   regular file    Device: 801h/2049d    Inode: 1225352     Links: 1    Access: (0775/-rwxrwxr-x)  Uid: ( 1000/    myzr)   Gid: ( 1000/    myzr)    Access: 2016-07-18 12:31:09.275109144 +0800    Modify: 2016-07-18 12:31:09.255109144 +0800    Change: 2016-07-18 12:31:09.255109144 +0800     Birth: -    [email protected]:~/myandroid/device/fsl-proprietary/test/bin$ md5sum /home/myzr/myandroid/out/target/product/sabresd_6dq/obj/EXECUTABLES/busybox_intermediates/busybox    7acb4ae8ca9bff56200c3d8ea54926a9  /home/myzr/myandroid/out/target/product/sabresd_6dq/obj/EXECUTABLES/busybox_intermediates/busybox    [email protected]:~/myandroid/device/fsl-proprietary/test/bin$ md5sum busybox     7acb4ae8ca9bff56200c3d8ea54926a9  busybox    [email protected]:~/myandroid/device/fsl-proprietary/test/bin$
