fedroa16 编译android 4.0.1

1. JDK 6

这个需要到sun的网站下载一个安装即可:http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html

下载完之后chmod再运行安装

2. 最新的android源码要求make的版本为3.81, make3.82的版本貌似有些兼容性的问题，试了下需要做些手脚才能顺利地downgrade回旧的版本

运行命令

结果出现错误提示

TheGPGkeyslistedforthe"Fedora13-i386-Updates"repositoryarealreadyinstalledbuttheyarenotcorrectforthispackage.
CheckthatthecorrectkeyURLsareconfiguredforthisrepository.

这是因为gpg key是fedora16版本的，降级回13的话需要用到13的key，上网搜索了下找到了之后放到/etc/pki/rpm-gpg/覆盖RPM-GPG-KEY-fedora-i386之后再重新运行上面的命令即可(记得备份原文件，降级完成后要把文件还原的，要不然系统升级会有问题)。

最后为了防止系统每次自动把make更新回3.82，我们在/etc/yum.conf里再添加一行来过滤掉make的自动升级

3. 缺失的系统工具

我的fedora16安装的时候选择的是softwaredevelopment的配置安装的，编译的时候出错需要安装的工具包括

4. 编译过程中的错误

a)perl错误

这个错误是由于fedora16中新的perl版本将switch的module拿掉了，需要修改webkit的源码来编译通过:

b) mutable错误

external/oprofile/libpp/format_output.h:94:22:error:reference‘counts’cannotbedeclared‘mutable’[-fpermissive]

解决方法：

external/oprofile里打patch或者自己手动修改文件

c) gtest错误
