我知道那里有许多描述此活动的演练和教程，但在阅读了其中的许多内容后，我仍然无法正常工作。如果有人有耐心逐步完成我采取的步骤（在下面发布）并提出我可能偏离轨道的地方，我将非常感激。我花了大约一天半的时间盯着制作文件和阅读演练，所以从字面上看，任何建议都会有所帮助。
环境：
- 我正在使用 Ubuntu 10.04 32 位虚拟机。
- 我从 64 位 Windows 7 托管
- 我的 Core 2 Duo 没有对 64 位虚拟机的硬件支持，所以我正在尝试针对 Android 2.1 内核进行编译
- 我已经从 Dapper 存储库安装了 Java 1.5 并删除了我的 1.6 安装
- 其余工具已根据 Android 开发文档获得…
根据 初始化构建环境：
爪哇：
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu dapper main multiverse"
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu dapper-updates main multiverse"
$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk
其他要求：
$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev libncurses5-dev x11proto-core-dev libx11-dev libreadline5-dev libz-dev libgl1-mesa-dev
$ sudo apt-get install gcc-multilib g++-multilib libc6-i386 libc6-dev-i386
然后从 下载源代码树：
回购：
$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
$ mkdir WORKING_DIRECTORY
$ cd WORKING_DIRECTORY
$ repo init -u https://android.googlesource.com/platform/manifest -b eclair
$ repo sync
$ gpg --import (imported the huge key)
从 建立系统：
初始化：
$ source build/envsetup.sh
选择目标：
$ lunch generic-user
构建代码：
$ make -j4
添加！ make -j4 的输出：

所以事实证明我在这里遇到了一些问题。我假设一旦我克服了这些问题，我就会拥有一个能够编译内核模块的环境。如果我错了，请纠正我。
接下来我进入包含我的 module.c 文件的目录，它是 makefile。 makefile的内容如下：
obj-m += mymodule.o
CROSS_COMPILE=~/WORKING_DIRECTORY/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi-
KERNEL_DIR ?= /home/<myuser>/WORKING_DIRECTORY
VERSION = v1.1
all:
make -C $(KERNEL_DIR) M=$(PWD) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE) modules
rm -rf *.c~
rm -rf *.mod*
rm -rf *.o
clean:
make -C $(KERNEL_DIR) M=$(PWD) clean
我对 make 和 makefile 的经验很少，但这对我来说看起来很合理。我对这个文件的主要关注是 KERNEL-DIR 变量。我为该变量尝试了几个不同的值，但在我不使用它的当前值的地方出现了各种错误。当然，它仍然可能是错误的，所以欢迎在这里发表任何评论。
所以，据我所知，我应该能够在没有参数或任何东西的情况下执行 make，并且会弄清楚它需要做什么。我已经尝试过使用和不使用 sudo 进行 make、make -f。所有四种排列产生相同的结果：
make -C /home/<myuser>/WORKING_DIRECTORY M=/home/<myuser>/Desktop/<MyModuleDir> ARCH=arm CROSS_COMPILE=~/WORKING_DIRECTORY/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi- modules

抱歉来晚了，希望对你有帮助：
http://tthtlc.wordpress.com/2011/12/29/how-to-write-a-kernel-module-on-android-sony-ericsson-xperia-arc-s/
我在我的 Sony Ericsson Xperia Arc S 上编写并测试了代码并且它有效（一般来说应该适用于任何 Android 手机）。
通过 adb 和 USB 连接，然后“su”到 root，“lsmod”列出了所有内核模块（一般来说，文章位于
http://web.archive.org/web/20121106004141/http://developer.sonymobile.com/2011/05/06/how-to-build-a-linux-kernel 很好地介绍了该做什么在 SonyEricsson 手机的 Linux 内核编译中）：
“android_module”是我通过
insmod android_module.ko插入的模块。方法如下：
首先将原始程序复制自：
http://rechtzeit.wordpress.com/2011/03/21/77/
或转载如下：
android_module.c ：
生成文件：
kernel所在的目录（上面的“-C”）就是kernel所在的目录。
以下命令将使用上面的 Makefile ：
如上所示，我使用的交叉编译器来自CodeSourcery。
在
insmod android_module.ko之后，您可以在dmesg输出中看到调试消息：“再见”是执行
rmmod android_module时。中间是来自内核中其他组件的调试消息。最后的话：
