I'm trying to compile and install a kernel. After download the code and configure the installation I have executed succesfully these comands:

# make bzImage
# make modules
# make

But when I try to execute this other command:

# make install

I've got this error:

[root@Asterix linux-4.18.5]# make install
sh ./arch/x86/boot/install.sh 4.18.5 arch/x86/boot/bzImage \
        System.map "/boot"
depmod: ERROR: could not open directory /lib/modules/4.18.5: No such file or directory
depmod: FATAL: could not search modules: No such file or directory
Kernel version 4.18.5 has no module directory /lib/modules/4.18.5
[root@Asterix linux-4.18.5]#

What am I doing wrong? How can I fix this error?

    Have you tried make install modules_install? – Andy Dalton Aug 28 '18 at 18:10
  • I think this is the last step, don't you? make bzImage, make modules, make, make install and make modules_install – José Carlos Aug 28 '18 at 18:12
  • Note that you don't need to run each as discrete steps. – Andy Dalton Aug 28 '18 at 20:09
  • Why I don't need to run all these steps? – José Carlos Aug 28 '18 at 20:11

    @JoséCarlos you can remove your "Edit I:" and instead post it as an answer. After some time you can accept your own answer as the solution. This helps preserve the "Question and Answer" structure of the site. – Kevin Kruse Aug 28 '18 at 21:00

Fixed it!!!

@Andy Dalton gave me the solution!!! The correct sequence of commands to create the new Kernel and install it is:

# make
# make install modules_install

Modern vanilla kernels even include direct packaging options for a few formats:

.../linux$ make help

[...]

Kernel packaging:
  rpm-pkg             - Build both source and binary RPM kernel packages
  binrpm-pkg          - Build only the binary kernel RPM package
  deb-pkg             - Build both source and binary deb kernel packages
  bindeb-pkg          - Build only the binary kernel deb package
  snap-pkg            - Build only the binary kernel snap package (will connect to external hosts)
  tar-pkg             - Build the kernel as an uncompressed tarball
  targz-pkg           - Build the kernel as a gzip compressed tarball
  tarbz2-pkg          - Build the kernel as a bzip2 compressed tarball
  tarxz-pkg           - Build the kernel as a xz compressed tarball

[...]

So make binrpm-pkg should build one (or a few) package(s) directly for easy handling.
