ubuntu 10.04 Android 编译环境搭建
装完ubuntu10.04sudo passwd root开启root账号，然后修改/etc/sudoers
XXX ALL=(ALL) NOPASSWD:ALL
然后开始安装软件包。我是虚拟机所以先装了vim和ssh，然后ssh上去。
1.先装JDK
http://source.android.com/source/initializing.html
但是报错：E: Package sun-java6-jdk has no installation candidate
改了几个源都不行
deb http://archive.canonical.com/ lucid partner已经失效。
最后查到https://launchpad.net/~sun-java-community-team/+archive/sun-java6
deb http://ppa.launchpad.net/sun-java-community-team/sun-java6/ubuntulucid main
deb-src http://ppa.launchpad.net/sun-java-community-team/sun-java6/ubuntulucid main
用这个源：
sudo apt-get update
有可能出错：
W: GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D8D75E403EBCE749
W: Failed to fetch http://ppa.launchpad.net/sun-java-community-team/sun-java6/ubuntu/dists/lucid/main/i18n/IndexNo Hash entry in Release file /var/lib/apt/lists/partial/ppa.launchpad.net_sun-java-community-team_sun-java6_ubuntu_dists_lucid_main_i18n_Index
解决办法是导入该源的公钥。
ubuntu12:~$ gpg --keyserver subkeys.pgp.net --recv-keys D8D75E403EBCE749
gpg: requesting key 3EBCE749 from hkp server subkeys.pgp.net
gpg: /home/jackyw/.gnupg/trustdb.gpg: trustdb created
gpg: key 3EBCE749: public key "Launchpad PPA for Community Team to provide regular Sun Java Updates" imported
gpg: Total number processed: 1
gpg: imported: 1(RSA: 1)
ubuntu12:~$ gpg --export --armor D8D75E403EBCE749 | sudo apt-key add -
ok
sudo apt-get update
然后遇到：
W: Failed to fetch http://ppa.launchpad.net/sun-java-community-team/sun-java6/ubuntu/dists/lucid/main/i18n/IndexNo Hash entry in Release file /var/lib/apt/lists/partial/ppa.launchpad.net_sun-java-community-team_sun-java6_ubuntu_dists_lucid_main_i18n_Index
E: Some index files failed to download. They have been ignored, or old ones used instead.
网上有两种解决办法：
1.sudo rm -rf/var/lib/apt/lists/partial/ppa.launchpad.net_sun-java-community-team_sun-java6_ubuntu_dists_lucid_main_i18n_Index
2.sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.bad
sudo mkdir -p lists/partial
sudo apt-get clean
cd
sudo apt-get update
sudo apt-get install sun-java6-jdk
安装之前我remove掉了openjdk：
sudo apt-get remove openjdk-6*
所以装完sun-java6-jdk以后不用再去配置使用哪个java实现，
sudo update-alternatives --config java
There is only one alternative in link group java: /usr/lib/jvm/java-6-sun/jre/bin/java
Nothing to configure.
2.装其余的软件包：
sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev libncurses5-dev x11proto-core-dev libx11-dev libreadline6-dev libgl1-mesa-dev tofrodos python-markdown libxml2-utils xsltproc
3.编译参照http://source.android.com/source/building.html
32位系统需要修改一些makefile
build/core/main.mk：
build_arch := $(shell uname -m)
ifneq (i686,$(findstring i686,$(build_arch)))
开始编译，报错：out/host/common/obj/JAVA_LIBRARIES/clearsilver_intermediates/javalib.jar] Error 41
在.bashrc加入：
export JAVA_HOME=/usr/lib/jvm/java-6-sun
export ANDROID_JAVA_HOME=$JAVA_HOME
host C: libneo_util <= external/clearsilver/util/neo_err.c
In file included from /usr/include/features.h:378,
from /usr/include/stdio.h:28,
from external/clearsilver/util/neo_err.c:14:
/usr/include/gnu/stubs.h:9:27: error: gnu/stubs-64.h: No such file or directory
make: *** Error 1
修改以下4个makefile
external/clearsilver/cgi/Android.mk
external/clearsilver/java-jni/Android.mk
external/clearsilver/util/Android.mk
external/clearsilver/cs/Android.mk.
# This forces a 64-bit build for Java6
#LOCAL_CFLAGS += -m64
#LOCAL_LDFLAGS += -m64
LOCAL_CFLAGS += -m32
LOCAL_LDFLAGS += -m32
/bin/bash: flex: command not found
make: *** Error 127
之前明明装了flex，奇怪，再次安装sudo apt-get install flex
接下来没有错误了
