VS2010遇到_WIN32_WINNT宏定义问题

最近拿到一个别人的工程,是使用VS.net创建的,而我的机器上只有vs2010,于是用自带的转换工具将它转换成vs2010的工程,转换之前我就很担心,怕转换完后会出问题,但是没有办法,我实在是不想再安一个vs.net了。

转完后果不其然真出了问题,在重新build工程时,报了一大堆错误,其中第一个就是“fatal error C1189: #error : This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended”,然后看错误的来源,竟然是atlcore.h,这我就无语了,这是mfc自带的文件,出错的可能性基本上为0,于是只好去请教谷大叔,发现很多人都遇到了这个问题,看了几篇博客和帖子后,大概明白了,应该是_WIN32_WINNT这个宏对应定义的系统的版本号,如果太低的话,编译器就会认为代码无法在当前的系统上编译。

在Project Property –> Configuration Properties–> C/C++  -> Command Line的Additional Options框中输入:

/D“_WIN32_WINNT=0×0501”

如果操作系统是Windows server 2003,则上述0×0501处改为0×0502;若为Windows 7,则为0×0601。
