网上找了一个编译脚本《Poco C++ ios 和 android平台编译脚本》，执行时出错：
ls: /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc-*: No such file or directory
进入poco看了一下，poco提供的配置（poco-1.4.6p4/build/config）中iOS的有3种：
iPhone
iPhone-clang
iPhone-clang-libc++
再进入网上找的那个脚本看下，它用的是配置1，似乎是针对老版本Xcode的，而我的Xcode 5的目录结构和编译器已发生变化，所以会出现上述错误。我改为配置2（另外还修改了原来脚本中lipo命令的错误），编译成功了。
（另外，配置3是使用C++11标准库，与配置2的区别见《Xcode中C++ Standard Library的选择》）
下面就是我修改后能正确运行了的Poco iOS编译脚本：
