is header file path reference in .c file included in object file (.o)

Question

I compile an example.c file that has the line:

#include "parse/properties/properties.h"

The compiler creates get an example.o file. Is the path to the header file included in the example.o file? or is that information external?

Answer 1

It may or may not, the object file format is not standardised (the standard does not even mention "object files"). A compiler might insert the #include for debugging purposes, or it may skip it completely.

Note also that #include'ing is done by the compiler in what the standard desrcibes as the first phase in translation, using a textual preprocessor; the #include-directive tells the preprocessor to copy verbatim and inplace the contents of another file. This happens long before actual object files would be produced

Answer 2

它是实现定义的，但是通常在使用调试选项（例如，gcc中的-g ）进行编译时，会包含文件路径以帮助您进行调试
