Question PATH included in .o file of device driver
Hello friends,

I am building one driver related to wifi. When I am looking its hex dump, I can see that it is including a path to one particular file of kernel headers. It is as under.
Code:

Is it okay if .obj includes path of kernel headers? What can I do to remove it? What are the possible reasons?



Thanks.

It might just because it's being built with debugging information. If you're building it the proper way, I don't think it matters as these files won't be required at runtime.

Hi, I am building it with arm-elf-gcc compiler. I removed -g in arm-elf-gcc and arm-elf-strip command, even more I gave --strip-all option in arm-elf-strip but still I can see those paths.

any other ideas?

Well, does it work? If it does you may be worrying about nothing.

What's in the header file? There's probably a constant defined in the file that then shows up in the compiled object file.

Even something like __FILE__ will cause that.
