编译 Android 源码时遇到的问题与解决方案

2017年9月7日 · 474 字

因为科研需要，我最近在编译Android源码，其间遇到的一些问题记录下来，以备日后查阅。

Android 6

Installing OpenJDK 7

AOSP only accepts OpenJDK 7 as compiling Java version. No HotSpot (Oracle JDK).

http://forum.ubuntu.org.cn/viewtopic.php?f=48&t=477645

Install via PPA.

bash
sudo add-apt-repository ppa:openjdk-r/ppa  
sudo apt-get update   
sudo apt-get install openjdk-7-jre

bison: No such file or directory

Error message:

text
/bin/bash: prebuilts/misc/linux-x86/bison/bison: No such file or directory

Solution:

bash
sudo apt-get install bison
sudo apt-get install  g++-multilib gcc-multilib

Error message:

text
clang: error: linker command failed with exit code 1 (use -v to see invocation)
build/core/host_shared_library_internal.mk:51: recipe for target 'out/host/linux-x86/obj/lib/libart.so' failed

解决方法：修改文件 art/build/Android.common_build.mk

diff
diff --git a/build/Android.common_build.mk b/build/Android.common_build.mk
index b84154b..8cf41c0 100644
--- a/build/Android.common_build.mk

 endif

另一种解决方法：修改文件 art/build/Android.common_build.mk

Android 7

OpenJDK 8

删除 openjdk-7-jre，安装 openjdk-8-jre。

Out of memory
