关于#pragma comment

[other123othe]

#pragma comment(linker,"/NODEFAULTLIB:LIBCMT.lib")
#pragma comment(linker,"/NODEFAULTLIB:LIBC.lib")

这两句话 什么意思？

[真相重于对错]

msdn 上有详细解释

#pragma ...是预处理指令，它的作用是设定编译器的状态或者是指示编译器完成一些特定的动作。 例如#pragma once：只要在头文件的最开始加入这条指令就能够保证头文件被编译一次。 例如#pragma hdrstop：表示预编译头文件到此为止，后面的头文件不进行预编译。 而#pragma comment的作用：该指令将一个注释记录放入一个对象文件或可执行文件中。 常用的lib关键字，可以帮我们连入一个库文件。如： #pragma comment(lib, "comctl32.lib") #pragma comment(lib, "vfw32.lib") #pragma comment(lib, "wsock32.lib") #pragma comment(linker,"/NODEFAULTLIB:LIBCMT.lib") #pragma comment(linker,"/NODEFAULTLIB:LIBC.lib") 这两行：就是忽略相关库的连接。 这是代码的实现，在IDE中的也可设置，就像2L和3L图示那样。 #pragma comment的作用具体请移步：http://baike.baidu.com/view/3487831.htm?fr=aladdin

加载库的，百度一下

正解！

加载lib库的，也可以再设置环境里配置，如果多个之间必须用分号。对于调用第三方类包的，用这种方式很方便，再开发环境里设置比较麻烦。

Linker Reference Home | Overview | How Do I | FAQ | Details LINK is a 32-bit tool that links Common Object File Format (COFF) object files and libraries to create a 32-bit executable (.EXE) file or dynamic-link library (DLL). Following is a comprehensive list of options for LINK.EXE. For information on how to specify an option, see Set Linker Options. This section also includes information on Compiler-Controlled LINK Options, LINK Input Files, and LINK Output.
