在Ubuntu14.04上编译Android4.0.1出现的几个问题

一. 工具

sudo apt-get install git-core gnupg flex bison gperf build-essential \

      zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \

      libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \

      libgl1-mesa-dev g++-multilib mingw32 tofrodos \

      python-markdown libxml2-utils xsltproc zlib1g-dev:i386

二.JDK

oracle 官网下载JDk6_29(bin文件，注意安装方法,环境变量，update-alternative等)   http://www.oracle.com/technetwork/java/javase/archive-139210.html

三.gcc/g++的版本

　默认的gcc g++版本为4.6.3,  将其改为4.4.步骤：

　sudo apt-get install gcc-4.4
　sudo apt-get install g++-4.4
　cd /usr/bin
　ls -l gcc*
　sudo mv gcc gcc.bak
　sudo ln -s gcc-4.4 gcc
　ls -l g++*
　sudo mv g++ g++.bak
　sudo ln -s g++-4.4 g++
　gcc -v
　g++ -v

四.源的问题

　　很多repo不能用，这个一般都可以： curl "http://php.webtutor.pl/en/wp-content/uploads/2011/09/repo" > ~/bin/repo

　　另外。init的时候用这个： repo init -u git://git.omapzoom.org/platform/manifest -b android-4.0.1_r1

　　之后 repo sync出现“fatal: ‘../platform/abi/cpp.git‘ does not appear to be a git repository”的解决方案，则打开.repo目录下的manifest.xml文件（命令vim manifest.xml）并找到fetch属性，在我的文件中显示fetch=".."，将fetch修改为 fetch="git://git.omapzoom.org"

五 .同步后出现的问题

1. 出错以下出错信息：

[plain] view plaincopy

1. Import includes file: out/target/product/mx3/obj/STATIC_LIBRARIES/libwebcore_intermediates/import_includes
2. target Generated: libwebcore <= external/webkit/Source/WebCore/css/tokenizer.flex

解决方法是安装perl的switch库：

[plain] view plaincopy

1. sudo apt-get install libswitch-perl

2.dalvik/vm/native/dalvik_system_Zygote.cpp:216:43: error: ‘setrlimit’ was not declared in this scope
err = setrlimit(contents[0], &rlim);
^
<command-line>:0:0: warning: "_FORTIFY_SOURCE" redefined [enabled by default]
dalvik/vm/native/java_lang_Float.cpp:1:0: note: this is the location of the previous definition
/*
^
make: *** [out/host/linux-x86/obj/SHARED_LIBRARIES/libdvm_intermediates/native/dalvik_system_Zygote.o] Error 1
make: *** Waiting for unfinished jobs....

解决办法
添加头文件#include <sys/resource.h>到以下文件
dalvik/vm/native/dalvik_system_Zygote.cpp

3.host Executable: emulator_renderer (out/host/linux-x86/obj/EXECUTABLES/emulator_renderer_intermediates/emulator_renderer)
/usr/bin/ld:
out/host/linux-x86/obj/EXECUTABLES/emulator_renderer_intermediates/main.o:
undefined reference to symbol ‘XInitThreads‘
//usr/lib/i386-linux-gnu/libX11.so.6: error adding symbols: DSO missing from command line
collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/emulator_renderer_intermediates/emulator_renderer] Error 1
make: *** Waiting for unfinished jobs....

解决办法：
修改development/tools/emulator/opengl/host/renderer/Android.mk文件
[email protected]:/home/dzt/android/WORKING_DIRECTORY# ls
abi cts docs frameworks Makefile prebuilt
bionic dalvik download.sh hardware ndk sdk
bootable development download.sh~ hs_err_pid6190.log out system
build device external libcore packages v8.log
[email protected]:/home/dzt/android/WORKING_DIRECTORY# gedit development/tools/emulator/opengl/host/renderer/Android.mk

添加一行：LOCAL_LDLIBS += -lX11 注意最好是复制过去，右边的容易写错
