自kernel.org遭受攻击，android.git.kernel.org梦见了电子羊，到kernel.org linux.com?linux.org 停机维护，android.git.kernel.org直接连域名解析都关了
这导致repo拼命想连接android.git.kernel.org，然后一次一次失败
但是repo还得继续用啊，默认情况下 都是从 android.git.kernel.org ?下载全套的repo工具集到.repo/repo目录下，再用这套工具集去下载git服务器上的源码库。
网上有个办法 http://carltao.blog.51cto.com/856514/667469 但我确实没找出作者修改了什么地方
于是继续google，总算被我找到完美的解决办法了继续阅读

红字部分是主要错误，“kmalloc”，“kfree”错误是由于缺少头文件引起的
#include <linux/slab.h>
添加后解决

<span style="color: #ff0000;">error: unknown field 'ioctl' specified in initializer</span> |
问题是由于2.6.36内核之后 去掉了原来的ioctl，添加两个新的成员，所以会出错
所以修改源文件中file_operations内
.ioctl 改为 .compat_ioctl 即可
OK，编译通过，警告咱就忽略了?:mrgreen:

上一篇中，介绍了如何编译、运行arm-linux-gdb 和 gdbserver，这一篇中介绍怎样结合Eclipse-cdt进行图形化编译调试
首先当然是使用CDT创建项目并添加源文件。

GCC C Compiler ：arm-linux-gcc GCC C Linker : arm-linux-gcc GCC C Assembler :arm-linux-ar |
做嵌入式Linux开发也不用再羡慕windows程序员VS集成开发环境的强大，我们同样能够搭建出给力的IDE。
今天在这里记录一下我使用Eclipse-cdt,gdb,gdbserver搭建远程arm调试的过程。
首先介绍下,嵌入式Linux的GDB调试环境由Host和Target两部分组成，Host端可以理解为本机，Target端为嵌入式设备。
Host端使用arm-linux-gdb，Target 端使用gdbserver。
调试时，应用程序在嵌入式目标系统上通过运行，而gdb调试在Host端。

可以通过export命令将/home/aliang/arm-gdb/bin目录加入PATH，使arm-linux-gdb可以直接使用，也可以直接拷贝到/usr/bin 或arm-linux-gcc同目录继续阅读

yaourt-Yet AnOther User Repository Tool
Yaourt是archlinux方便使用的关键部件之一，但没有被整合到系统安装中的工具。建议在装完系统重启之后，更新完pacman和基本系统之后，就安装这个工具。
最简单安装Yaourt的方式是添加Yaourt源至您的 /etc/pacman.conf:继续阅读
