TCPSocket v1.0 for cocos2d-x下载

下载地址：http://files.cnblogs.com/elephant-x/TCPSocketLibs_V1.0.rar

这是自己封装的一个TCPSOCKET包，是独立于cocos2d-x的，使用的时候，请把该项目加入到cocos2d-x里面去，再在项目里面包含libSocket项目和libSocket.lib

1、独立线程接收，异步连接服务端，防止界面卡的情况。

2、支持WIN32和LINUX。

3、编译linux时，在项目的Android.mk文件里必须添加下面两行：

　　LOCAL_WHOLE_STATIC_LIBRARIES += socket_static

　　$(call import-module,../CustomLibs/libSocket)

如图：

4、在Application.mk里面加入-std=c++11，因为源代码里面用到了c++11(VS2012)才有的std::bind和std::function，不支持c++11以下的编译器

APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -DCOCOS2D_DEBUG=1 -std=c++11

如果是c++11以下的编译器，可以参考：

“function对于回调函数、将操作作为参数传递等十分有用。它可以看做是C++98标准库中函数对象mem_fun_t, pointer_to_unary_function等的替代品。同样的，bind()也可以被看做是bind1st()和bind2nd()的替代品，当然比他们更强大更灵活。”

自行改写。。

使用例子代码，可以拷贝到HelloCpp项目里去测试。
