我想按照本指南在 Ubuntu x64 上构建和运行 Dalvik VM PATH/TO/AOSP/dalvik/docs/hello-world.html：.

我的代码分支和主机是这样的：

============================================
PLATFORM_VERSION_CODENAME=AOSP
PLATFORM_VERSION=4.2.1.2.4.8.16.32.64
TARGET_PRODUCT=full_x86
TARGET_BUILD_VARIANT=eng
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=x86
TARGET_ARCH_VARIANT=x86
HOST_ARCH=x86
HOST_OS=linux
HOST_OS_EXTRA=Linux-3.0.0-28-generic-x86_64-with-Ubuntu-11.10-oneiric
HOST_BUILD_TYPE=release
BUILD_ID=OPENMASTER
OUT_DIR=out
============================================

首先，我在 Ubuntu 上构建 Dalvik：

source build/envsetup.sh
lunch 2[full_x86-eng]
make dalvikvm core dexopt ext framework android.policy services

然后我编译Java代码并打包它。

之后我像这样运行它，但它失败了：

guohai@KNIGHT:~/dev/src/android/git/aosp$ ./rund -cp Foo.jar Foo

任何机构都可以提供一些线索吗？

日志如下：

在我更改ANDROID_ROOT我的启动脚本后，它就可以工作了。我的解决方法如下：

#!/bin/sh

# base directory, at top of source tree; replace with absolute path
base=`pwd`

# configure root dir of interesting stuff
root=$base/out/host/linux-x86
export ANDROID_ROOT=$root

# configure bootclasspath
bootpath=$base/out/target/product/generic_x86/system/framework
export BOOTCLASSPATH=$bootpath/core.jar:$bootpath/ext.jar:$bootpath/framework.jar:$bootpath/android.policy.jar:$bootpath/services.jar

export LD_LIBRARY_PATH=$bootpath/lib:$LD_LIBRARY_PATH

# this is where we create the dalvik-cache directory; make sure it exists
export ANDROID_DATA=/tmp/dalvik_$USER
mkdir -p $ANDROID_DATA/dalvik-cache

exec $root/bin/dalvikvm -Xdexopt:none $@
