终于到了编译范例的时候了，范例在APPS目录里，好兴奋呀。。。
开始编译：
zhaowei@zhaowei-ubuntu:~/toolchain/apps/HelloToolchain$ make
arm-apple-darwin9-gcc -lobjc -bind_at_load -framework Foundation -framework CoreFoundation -framework UIKit -w -o HelloToolchain HelloToolchain.o
ld: library not found for -lobjc
collect2: ld returned 1 exit status
make: *** [HelloToolchain] 错误 1
看见没有，又报错了。在官方讨论区我找到解决方法。看下面：
Here's the solution I used (thanks brian.cr...):
Build the toolchain
In ~/Projects/iphone/toolchain/toolchain/sys, rename folder System to System2
In ~/Projects/iphone/toolchain/toolchain/sys/usr, rename folder lib to lib2
Copy folder ~/Projects/iphone/toolchain/sdks/iPhoneOS3.1.2.sdk/System to ~/Projects/iphone/toolchain/toolchain/sys
Copy folder ~/Projects/iphone/toolchain/sdks/iPhoneOS3.1.2.sdk/usr/lib to ~/Projects/iphone/toolchain/toolchain/sys/usr
Try to build HelloToolchain? again using instructions on this page (above).
Hope that helps. This was the only error I encountered using the toolchain.sh script
重新编译，看输出结果，证明我们编译成功了。呼呼，接下来就是要上传到IPHONE了。
zhaowei@zhaowei-ubuntu:~/toolchain/apps/HelloToolchain$ make
/home/zhaowei/toolchain/toolchain/pre/bin/arm-apple-darwin9-gcc -lobjc -bind_at_load -framework Foundation -framework CoreFoundation -framework UIKit -w -o HelloToolchain HelloToolchain.o
使用这个命令上传到IPHONE：
Navigate to the apps/HelloToolchain directory and run the following commands, noting that you must set "IP" to the address of your iPhone and change the path as appropriate:
cd ~/toolchain/apps/HelloToolchain
IP=xxx.xxx.xxx.xxx PATH=../../toolchain/pre/bin/:$PATH make deploy
上传会需要你输入密码，我居然试了半天，密码错误，怎么可能，默认的密码都进不去，后来才想起，是自己当初玩的时候修改了密码
默认密码：！1.02 的系统密码是dottie. 1.1.1密码是alpine.
我的密码是：＊＊＊＊＊ 。哈哈。
记得修改密码哦。
上传成功的样子：

脚本功能: 定期对一些项目进行完整备份.
project.lst 文件格式如下:
project1
project2
备份脚本如下:
