在命令行上使用Visual Studio进行编译时如何包含库？ [英] How to include libraries when compiling with Visual Studio on command line?

问题描述

我正在尝试在命令行上使用Visual Studio 2008构建程序。
阅读演练：在命令行上编译本机C ++程序。
我尝试了以下操作：

I'm attempting to build a program with Visual Studio 2008 on the command line. After reading Walkthrough: Compiling a Native C++ Program on the Command Line. I tried the following:

运行vcvaralls.bat来设置环境：

Run the vcvaralls.bat to setup the enviroment:

"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\vcvarsall.bat"

编写此简单的C ++应用程序：

Wrote this simple C++ application:

#define _WIN32_WINNT 0x501
#include <windows.h>
INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                   LPSTR lpCmdLine, int nCmdShow)
{
    MessageBoxA(0,"Hello","Hello",MB_OK);

    return 0;
}`

并尝试对其进行编译：

cl /EHsc /GA simple.cpp

发生这种情况：

/out:simple.exe
simple.obj
simple.obj : error LNK2019: unresolved external symbol __imp__MessageBoxA@16 referenced in function _WinMain@16
simple.exe : fatal error LNK1120: 1 unresolved externals

这使我相信我需要包括user32.lib或类似内容。
我无法从Visual Studio手册中弄清楚该怎么做。

Which leads me to believe that I need to include user32.lib or similar. I cant figure out from the visual studio manuals how to do that.

推荐答案

是的，要使用MessageBox，您需要至少与User32.lib链接，如此处。使用：

Yes, to use MessageBox you need to link at least with User32.lib, as shown here . Use:

cl /EHsc /GA /MT simple.cpp User32.lib

/ MT选择运行时库。在此示例中，我使用了多线程静态库。

/MT chooses the Run-time library. In this example I used multi-threaded static library.
