我如何编译这个？我需要整个Android源代码树吗？还是我做错了什么

存储库包含

Android.mk

文件。我在HP Pavilion g7-2269wm上使用的是64位基本操作系统freya（基于Ubuntu）。安装了最新的SDK和NDK

在新克隆ART的源代码并通过运行以下命令进行编译之后

git克隆https://android.googlesource.com/platform/art
cd艺术
git checkout棉花糖cts发布
导出NDK_项目路径=$PWD
ndk build APP_build_SCRIPT=Android.mk

我明白了

echo$NDK\u项目路径的输出

/home/suici/AndroidRuntime/art

ls$PWD的输出
Android.mk    cmdline   dex2oat       MODULE_LICENSE_APACHE2  patchoat     test

我下载了ASOP源代码，并为x86_64构建了它。在一个文件夹中，我可以找到我想要的dalvikvm
二进制文件。但我有个问题
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
中，并将out/host/linux-x86/lib64/
中的所有内容复制到/usr/bin/x86\u 64-linux-gnu/
中，然后运行ldconfig-v-n/usr/lib
和ldconfig-v-n/usr/lib/x86\u 64-linux-gnu/
，以获取所有信息Android LIB（64和x86）
执行/dalvikvm
时，我得到

更换！！！路径到AOSP指向AOSP文件夹的路径。然后运行mkdir-p$ANDROID_DATA/dalvik cache
创建文件夹
Dalvik使用的是32位，而不是64位。这是一台运行初级操作系统freya的64位计算机
将echo NDK_项目路径
和ls~/art@m0skit0的结果发布到answer@m0skit0我已经解决了这个问题，但它需要作为32位运行，这是恼人的，可能会很慢（不知道，但我的Nexus 9 64位速度很快，因为它使用64位ART/Dalvik）
