Question

我正在尝试使用MSBuild构建一个非常简单的C程序。以前这是由一个使用Visual Studio的实习生组成的，但我们不会在这里使用VS而且我希望这个用MSBuild构建，所以我可以自动化它。

我已经在MSDN和其他参考文档的演练之后从头构建了我的vcxproj文件。我能够编译obj文件没问题，但链接步骤似乎永远不会运行所以我没有得到可执行输出。

在AppDrv.c文件中有一个名为main的函数，可以安全地假设链接器将检测到它作为入口点，或者我是否需要手动告诉msbuild一些它是如何存在的？

这是我的vcxproj的全部内容。我在文档中找不到任何说明我需要告诉它链接的内容，如果CL步骤完成，它是不是会自动发生？我是否需要以某种方式明确列出要链接的obj文件，或者MSBuild可以自己解决这个问题吗？

这是我用来启动构建的命令：

MSBuild.exe slipwinhelper.vcxproj /p:configuration=Debug /p:platform=Win32 /p:OutDir=target\ /nologo /t:Clean;Build;Info

更新：我通过覆盖AfterBuild事件来运行链接任务：

  <Target Name="AfterBuild">
      <Link Sources="Debug\AppDrv.obj;Debug\Buffers.obj;Debug\SingleThreadAsync.obj;Debug\Slip.obj;Debug\Utils.obj" />
  </Target>

但是现在它在代码中给了我未解决的SetupApi调用外部。我尝试将SubSystem更改为Windows，但这似乎不起作用。

与VS生成的文件快速比较显示了一堆差异/缺乏属性，包括来自VS的文件

<ConfigurationType>Application</ConfigurationType>

而你指的是Console这不是msbuild认可的东西。

msbuild链接步骤不运行
