c++ - 如何在驱动程序的 INF 文件中使用变量？

Question

我正在使用 Visual Studio 2015 和 WDK 10 开发 NDIS 过滤器驱动程序。要求是使用 INF 文件中的不同 FilterClass(compression 和 ms_medium_converter_128)编译驱动程序。我不想维护两个几乎相同的 INF 文件，除了不同的 FilterClass。

我的问题是:有什么方法可以在 INF 文件中使用变量或宏吗？ 这样我就可以在 Visual Studio 中使用不同的配置来控制实际编译的 INF 内容。效果是这样的:

HKR, Ndi,FilterClass,, %MACRO_OR_VAR_FILTER_CLASS%

然后我可以在 VS 中控制 %MACRO_OR_VAR_FILTER_CLASS%。

最后附上我的整个INF文件:

我认为 Inf“语言”中没有这样的功能。 但是您可以通过使用可以接受 VS 构建宏的简单预构建脚本轻松实现您的目标。这样的脚本可以将所需的值注入(inject)到您的 inf 文件中 - 您可以使用 VS 宏从脚本访问 inf，例如 ($SolutionDir)、($ProjectDir) 等. 该脚本可以集成到 VS 解决方案中，因此编写后无需额外的工作即可运行。
