error LNK2005: "void * __cdecl operator new(unsigned int)" (??2@YAPAXI@Z) already defined in LIBCMT.

在vs2012 中将程序改为release 版本 点击所选项目--》properties-----》Configurations: 中选择release 然后从新编译工程即可；

环境：vs2012 中 在非MFC程序（使用standard window library）中，添加MFC支持，静态连接MFC库 发生以下错误

Solution One: Force Linker to Link Libraries in Correct Order

On the Project menu, click Settings.
In the Settings For view of the Project Settings dialog box, click to select the project configuration that is getting the
link errors.
On the Link tab, click to select Input in the Category combo box.
In the Ignore Specific Default libraries box, insert the library names (for my example,
uafxcw.lib;LIBCMT.lib).

Note The linker command-line equivalent in /NOD:<library name>.
In the Additional Dependencies box, insert the library names. You must make sure that these are listed in order and as the first two libraries in the line (for my example,

uafxcw.lib;LIBCMT.lib).
