Error compiling Linux-kernel - "make: *** No rule to make target. Stop."

Teso · 07-27-2020, 06:07 AM

After Ubuntu 19.10 carried an update/upgrade, the Linux-kernel was updated to version "linux-5.3.0-xx-generic". I uninstalled it with the command:

Code:

apt remove --purge *5.3.0-xx* && apt autoremove && apt autoclean

I have uninstalled kernels this way many times and never had a problem, everything worked fine.
Now when I try to compile a kernel, I get this error message:

Code:

root@linux:/usr/src# make O-/build/linux-kernel/linux-5.7.10-test/ makemenuconfig
make: *** No rule to make target 'O-/build/linux-kernel/linux-5.7.10-test/'.  Stop.

Apparently files that were needed for compilation were deleted.
I'm not sure how to fix it...

--EDIT--

Before anyone asks this question...
Yes, i installed the necessary dependencies.

You should go into the directory you extracted the kernel sources (I guess it's /build/linux-kernel/linux-5.7.10-test) and run make from there, e.g:

Code:

cd /build/linux-kernel/linux-5.7.10-test
make menuconfig

I installed the dependencies one more time and now "make menuconfig" works.
make menuconfig works in the "/build/linux-kernel/linux-5.7.10-test" directory, but the output douse not work. i have to "cd" in to "/usr/src/linux-5.7.10-test" the output directory is in "/build/linux-kernel/linux-5.7.10-test" that`s what the README says:

Installing the kernel source
----------------------------

- If you install the full sources, put the kernel tarball in a
directory where you have permissions (e.g. your home directory) and
unpack it::

xz -cd linux-5.x.tar.xz | tar xvf -

Replace "X" with the version number of the latest kernel.

Do NOT use the /usr/src/linux area! This area has a (usually
incomplete) set of kernel headers that are used by the library header
files. They should match the library, and not get messed up by
whatever the kernel-du-jour happens to be.

Build directory for the kernel
------------------------------

When compiling the kernel, all output files will per default be
stored together with the kernel source code.
Using the option ``make O=output/dir`` allows you to specify an alternate
place for the output files (including .config).
Example::

kernel source code: /usr/src/linux-5.x
build directory: /home/name/build/kernel

To configure and build the kernel, use::

cd /usr/src/linux-5.x
make O=/home/name/build/kernel menuconfig
make O=/home/name/build/kernel
sudo make O=/home/name/build/kernel modules_install install

Please note: If the ``O=output/dir`` option is used, then it must be
used for all invocations of make.

Am I doing something wrong?
OK, let`s do it step by step:
First i navigate in to my build directory "cd /build/linux-kernel"
Then i extract the tar-ball "xz -cd /root/Downloads/linux-5.7.10.tar.xz | tar xvf -"
Now the output directory is in "/build/linux-kernel/linux-5.7.10-test"
Make a new directory "mkdir /usr/src/linux-5.7.10-test"
I chance in to the directory "cd /usr/src/linux-5.7.10-test"
And run the command "make O=/build/linux-kernel/linux-5.7.10-test menuconfig"

Code:

root@linux:/usr/src/linux-5.7.10-test# make O=/build/linux-kernel/linux-5.7.10-test/ menuconfig
make: getcwd: No such file or directory
make: *** No rule to make target 'menuconfig'.  Stop.

You're making it unnecessarily complicated. I'm not surprised things go wrong.

The simplest way to build a kernel is this:

1)Unpack the tarball in your home directory (or wherever else you usually do this kind of work). Don't use a system directory.

2) cd into the new toplevel directory. Do not create any others.

3) Copy over your existing kernel configuration file as .config.

4) Type "make menuconfig"

5) Browse the menu and make any changes you want. Look especially at anything labelled NEW.

6) Exit and type "make"

7) When the build is finished, copy the new bzImage from arch/x86/boot to your boot directory, giving it a suitably informative name. Copy also the system map and the .config file. Then use "make modules_install" to install the corresponding modules.

8) Update GRUB.

I Thanks, I know how to compile a kernel.
This time I want to do it as described in the README.rst file.
I'm just trying to follow the installation instructions in the: ~/Documentation/admin-guide/README.rst
But for some reason it doesn't work.
