假设我正在构建一个相当大的代码库

我在一个命令中使用 Visual c++ 编译器中的一大堆编译器标志编译一大堆文件，如下所示：

假设我得到一个 ICE，它位于某个源文件（翻译单元）直接或间接包含的头文件中，有没有办法直接或间接追踪哪个翻译单元（源 .cpp 文件）（通过其他一些头）包括发生ICE的头？

我在控制台中获得的输出似乎真的很混乱，以至于我无法通过查看它轻松找出哪个源文件包含具有 ICE 的标头。

如果您使用cl /E而不是编译/c，您将获得输出（stdout默认情况下），并在文件首次合并到翻译单元时使用以下符号：

#line 1 "...file [path and] name..."

可以找一下#line 1报ICE的header对应的那一行，然后回看之前#line的s，看看哪些文件直接和间接包含了它。

例子

我下面的评论是内联的，被 [[[三方括号]]] 包围。#line请记住在...之后通过行号“1”来推断源文件是新包含的还是正在“返回”的其他文件。
