我知道有很多关于这个活动的步骤指引和教程在网上流传，但是即使我看了很多，仍然无法使它运作起来。如果有人能够有耐心浏览我所采取的步骤（如下所示），并指出我可能偏离轨迹的地方，我将不胜感激。我已经花了一天半的时间盯着make文件，并阅读了指引和教程，所以任何建议都会有用。
环境：
- 我正在使用一个Ubuntu 10.04的32位虚拟机。
- 我从一个64位的Windows 7主机进行托管。
- 我的Core 2 Duo没有64位虚拟机的硬件支持，所以我正在尝试编译Android 2.1内核。
- 我已经从Dapper repo安装了Java 1.5，并删除了我的1.6安装。
- 其余的工具已经根据Android开发文档获得...
根据初始化构建环境：
Java:
$ 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
接下来是从下载源代码树部分摘录：
Repo:
$ 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)

看起来我在这里遇到了一些问题。 我认为，一旦我解决了这些问题，我就能够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文件和它的makefile的目录。 下面是makefile的内容：
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，但这看起来还算合理。我担心的是KERNEL-DIR变量。我尝试了几个不同的值，但出现了各种各样的错误，而当前值却没有问题。当然，它仍然可能是错误的，所以在此留下任何评论都是受欢迎的。
据我所知，我应该能够执行无需参数的make命令，它将弄清楚需要做什么。我尝试过make、make -f以及带有sudo和不带sudo的两种方式。所有四种排列组合产生的结果都相同:
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

我猜最后一句听起来相当可疑，但我不知道该怎么做。 除了我提到的几件奇怪的事情外，似乎这一切都进行得很顺利。 然而，在整个过程完成后，我无法找到 *.ko 文件所在的位置。 我在我的家目录下执行了 ls -alRg | grep *.ko，但没有发现任何结果。 我被难住了。如果我能提供更多信息、运行任何测试或尝试其他任何不同的方法，我会经常查看。
