为iphone及iphone simulator编译poco库

./configure --config=iPhone --prefix=/libs/pocos --static --notests --nosamples

＃./configure --config=iPhoneSimulator --prefix=/libs/pocos --static --notests --nosamples

由于系统升级到了mac os x 10.7.4，xcode目录也变到了/Applications/Xcode.app，所以要编译iphone版的就要做些修改，找到build/config/iPhone文件打开编辑，修改如下：

IPHONE_SDK_VERSION = 5.1
GCC_VER = 4.2

IPHONE_SDK             ?= iPhoneOS

IPHONE_SDK_ROOT         = /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs

POCO_TARGET_OSARCH     ?= armv7

TOOL_PREFIX            ?= /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/

make 

make install
