[ERROR] HELP NEEDED

[ERROR] HELP NEEDED

[Gilbert Adikankwu]

Hello fellow community member,

I'm trying to build the kernel on Ubuntu 22.04 LTS natively installed
on my computer and I'm getting this error message:

arch/x86/entry/thunk_64.o: warning: objtool: missing symbol table
make[2]: *** [scripts/Makefile.build:361: arch/x86/entry/thunk_64.o] Error 1
make[2]: *** Deleting file 'arch/x86/entry/thunk_64.o'
make[1]: *** [scripts/Makefile.build:497: arch/x86/entry] Error 2
make: *** [Makefile:1764: arch/x86] Error 2

It seems like a file is missing but I don't know if that is possible
because I just cloned the repository and didn't touch any file.

Please advise
Gilbert

Maybe there was a previous error.  Start over with make clean and then use
just make without the -j option.  It will take time, but you can see
better what is going on.  You can also do make >& out.  Then you will have
all of the output in the file out, and you can look through it to see what
succeeded and what failed.

Hello Julia,

I deleted the kernel and redownloaded it. It is compiling now.

Thanks for your help
Gilbert

Please don't top-post; reply inline with appropriate context instead.
This allows readers to easily follow and understand the conversation flow.

Did you download the tarball or cloning via git?

Thanks.

You should always clean up the tree first (`make mrproper`), then do
the build as usual. To speed up build time, you can try copying your
current kernel configuration (can be found either in `/boot/` directory
or in `/proc/config.gz`), then trim it up with `make localmodconfig`.
Make sure that all options needed by your computer are enabled (you
may have to plug all peripherals available on your hand) as well as
options related to kernel subsystem/driver you're hacking. For more
information, see Documentation/admin-guide/quickly-build-trimmed-linux.rst.

Thanks.
