 Posted: Wed Dec 11, 2024 6:24 pm Post subject: depclean after kernel download |
 |
|
my issue is that i messed up by performing a depclean prior to fully installing my kernel after an update... the issue is perfectly described in this post by NeddySeagoon that describes exactly what i just did wrong.
here is the link to original quote and the post is also pasted below

| Quote: | C666PO,
New kernels don't have a .config file at all.
When you run make menuconfig, the make system loads a defaultconfig which is mostly no use to anyone.
Here's what happened to you. You did an update that fetched new kernel sources.
The update went well and you ran
Code:
emerge --depclean
That removed all the downloaded files from /usr/src/linux, which points to an older kernel that the one your update fetched.
The key here is 'downloaded files'. Your .config and all the generated files are still there but /usr/src/linux/Makefile has gone as it was downloaded.
Hence your error.
Copy /usr/src/linux/.config to your new kernel source tree and do the kernel update dance.
You can do something similar with gcc when you have a new gcc installed but not yet selected.
--depclean will remove your active gcc. That's scary the first time.
What you are reporting is normal behavior.
Its possible emerge your old kernel again if you really need it but you need to specify the slot, as you don't want the newest kernel.

those that do backups
those that have never had a hard drive fail |
the only issue, is he doesn't say exactly how to get my makefile back. i tried to look through the kernel upgrade documentation but am not able to figure this out.
basically i cannot perform make oldconfig or any make function, my makefile is gone, as described above.

OP: welcome to the forums. I suggest that you use Preview before you Submit a post, so that you can review how well (or not) your BBcode comes through. In your case, it's a bit of a mess. I think you could've gotten something more usable, and more readily, by opening a reply-with-quote of Neddy's post, then copying that text into your new post here without attempting to modify it.
As for your implied question, Neddy answered it: don't do that. More specifically, rather than trying to retrieve the Makefile and associated kernel sources of the by-definition non-current kernel, you should use a now-current kernel and update your .config accordingly. Neddy also did explain how to get back the older kernel if you really need it. |
