我下载了ASOP源并将其构建为x86_64.在一个文件夹中，我可以找到dalvikvm二进制文件.但我对此有疑问.

I downloaded the ASOP source and built it for x86_64. In a folder I could find the dalvikvm binary which is what I wanted. But I have a problem with it.

首先安装所有Android库，我将out/host/linux-x86/lib/中的所有内容复制到/usr/bin，并将out/host/linux-x86/lib64/中的所有内容复制到/usr/bin/x86_64-linux-gnu/，并运行ldconfig -v -n /usr/lib和ldconfig -v -n /usr/lib/x86_64-linux-gnu/以获取所有Android库(64和x86) )

First to install all the Android libraries I copied everything in out/host/linux-x86/lib/ to /usr/bin and everthing in out/host/linux-x86/lib64/ to /usr/bin/x86_64-linux-gnu/ and ran ldconfig -v -n /usr/lib and ldconfig -v -n /usr/lib/x86_64-linux-gnu/ to get all the Android libs (64 and x86)

执行./dalvikvm时我得到

运行dalvikvm --32时，通过添加以下几行来修改~/.bashrc后，一切似乎都能正常工作.

When running dalvikvm --32 everything seems to work correctly after modifying my ~/.bashrc by adding the following lines to it.

export ANDROID_ROOT=!!!PATH-TO-AOSP!!!/out/debug/host/linux-x86/product/generic_x86_64/system

# configure bootclasspath
export BOOTCLASSPATH=$ANDROID_ROOT/framework/core.jar:$ANDROID_ROOT/framework/ext.jar:$ANDROID_ROOT/framework/framework.jar:$ANDROID_ROOT/framework/android.policy.jar:$ANDROID_ROOT/framework/services.jar

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

将!!!PATH-TO-AOSP!!!替换为AOSP文件夹的路径，然后运行mkdir -p $ANDROID_DATA/dalvik-cache创建文件夹.

Replace !!!PATH-TO-AOSP!!! with the path to your AOSP folder.Then running mkdir -p $ANDROID_DATA/dalvik-cache to create the folders.

Dalvik是在32位系统上运行，而不是在64位系统上运行.这是一台运行基本操作系统freya的64位计算机

Dalvik is working in 32-bit but not in 64-bit.This is a 64-bit computer running elementary OS freya
