I'm having some nasty error with one header file being included with different linkages (namely, stdio.h with and withoun "extern C"). So, I need to find where one specific header file is included.
我在一个头文件中出现了一些令人讨厌的错误，其中包含了不同的链接(即stdio)。h with和withoun“extern C”)。因此，我需要找到包含一个特定头文件的地方。
I am aware of doxygen but unfortunately the header I'm interested is stdio.h, which is also included by Qt. So the only way (that I'm familiar with) to use doxygen - is to scan entire Qt folder. That could take forever.
我知道doxygen，但不幸的是，我感兴趣的标题是stdio。h，也包括Qt，所以使用doxygen的唯一方法是扫描整个Qt文件夹。这可能需要很长时间。
So, is it possible to find out, where one header is included, without drawing include graphs for every headers in the project? Or is there some other way of solving this?
那么，是否可以找到一个标题包含的地方，而不包括项目中每个头的图形?或者还有其他的解决方法吗?

You can try gcc -E to preprocess the file and see where the header file comes from;
您可以尝试gcc -E来预处理该文件，并查看头文件的来源;
Or you can just search your -Ipath where the header file is.
或者你可以搜索你的-Ipath文件头文件。

I'd use grep:
我使用grep:
grep --color --binary-files=without-match -R -n -i "stdio.h" *
grep——颜色——二进制文件=不匹配-R -n -i“stdio”。h”*
that will recursively search down a tree, examining every text file for stdio.h, printing each match with the file name and line number where it was found.
这将递归搜索树，检查每个文本文件。h，打印每个匹配的文件名和行号。
