[SOLVED] Which IDE should I ideally use for browsing Linux Kernel Source Code?

purnish_dave · 03-04-2018, 10:13 AM

If I come across a variable and function name which isn't defined in the same file it's practically impossible to find in other files.
Which command I can use or which IDEs can I use for this?

Thanks for your time.

You can use grep.

Code:

$ grep -r string directory

will return every matching string in all files and subdirectories in directory.

originally it was ctags to do that, you do not need any kind of IDE.

Just to add to pan64: Once you tags are generated, advanced editors like vim or emacs have commands to jump from the name of a function to it's definition, etc...

Thanks for the answer. I will use ctags and come back if I have any more questions.

I set up CTags. It's really cool. I use it with vim.

I have one strange issue with ctags.

There is a line in the code like this

Code:

struct bio *bio;

When I run

Code:

:tag bio

it returns to the same line.

I however want it to go to where the struct is defined.

How do I do this?

I figured it out.

All I have to do is to type

Code:

:ts bio
