我正在尝试使用 MSBuild 构建一个非常简单的 C 程序。以前这是由一名实习生使用 Visual Studio 组合在一起的,但我们不会在这里使用 VS,我希望它是用 MSBuild 构建的,这样我就可以自动化它。
我按照 MSDN 上的演练和那里的其他引用文档从头开始构建了我的 vcxproj 文件。我能够毫无问题地编译 obj 文件,但链接步骤似乎从未运行过,所以我没有得到可执行文件输出。
在 AppDrv.c 文件中有一个名为 main 的函数,是否可以安全地假设链接器会将其检测为入口点,或者我是否需要手动告诉 msbuild 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我需要告诉它链接的内容,如果 CL 步骤完成,它不应该自动发生吗?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?

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 事件让它运行链接任务:
<Target Name="AfterBuild">
<Link Sources="Debug\AppDrv.obj;Debug\Buffers.obj;Debug\SingleThreadAsync.obj;Debug\Slip.obj;Debug\Utils.obj" />
</Target>
但现在它在代码中的 SetupApi 调用上给我 Unresolved external 问题。我已尝试将子系统更改为 Windows,但似乎不起作用。
最佳答案
与 VS 生成的文件的快速比较显示了一堆差异/缺少属性,包括来自 VS 的文件有
<ConfigurationType>Application</ConfigurationType>
而您指定的是 msbuild 无法识别的 Console
。
