Kernel sources for current kernel?

[mxlinuzuzer]

Hi,

I want to use my own .config. Where do I get the kernel source from for 4.19.5? I need the headers for it too for installing Virtualbox. Would like to install the lasted VB 6.0. Will 4.19.5 work?

VirtualBox 6.0.4 is already in the testing repository. I suggest you use that rather than installing your own that you got from somewhere else.

[mxlinuzuzer]

Thank you! Do you know where I can get the kernel source from?

[JayM]

Probably from the source repositories, I would imagine. They would need to be enabled in MX Repo Manager. I haven't done so, so I don't know if kernel sources are there or not.

Vbox 6.X will build on the 4.19 kernel, even up to the 5.0 kernel.

If you're going to build your own kernel, you also have to build and install your own headers. MX already has the MX kernel headers installed.

You can get the kernel source by running

Code: Select all

sudo apt-get install linux-source-4.19

Description: Linux kernel source for version 4.19 with Debian patches
This package provides source code for the Linux kernel version 4.19. This
source closely tracks official Linux kernel releases. Debian's
modifications to that source consist of security fixes, bug fixes, and
features that have already been (or are believed to be) accepted by the
upstream maintainers.

which will install it into /usr/src. I would recommend moving it out of /usr/src to your home folder if you want to work on it.

There are also methods of getting it with "sudo apt-get source", or just get the orig.tar.xz tarball from our repo, which is the original unaltered source direct from upstream. http://mxrepo.com/mx/repo/pool/main/l/linux/

I do have questions about what procedure you plan to use to build the kernel, though, and what you want to change in the config. You probably should also look into using a newer 4.19 kernel source from our test repo, or even linux-source-4.20 from there, for security and bugfix reasons.

We backport upstream Debian kernels for MX using the Debian packaging system, which do take quite a while to build on older machines and need over 40 GB of free space on the hard drive. Liquorix kernels, even though they enable more drivers than Debian, are much faster to build and take maybe 7 GB of free space.

Thank you! I have compiled 5.0.4 without root, and is running it now, but there's no kernel headers for it.

[Stevo]

What commands did you use to manually build it? Often you have to add something like "enable-headers" to get a separate header package. We really can't troubleshoot the procedure without any details.

Thanks for helping me.

wget the source from kernel,org. Verified it and extracted it.
Copied the .config backup to ~/Downloads/linux-5.0.4/

Code: Select all

sudo apt install build-essential libncurses-dev bison flex libssl-dev libelf-dev

Code: Select all

make oldconfig

as the .config was made from an earlier kernel version.

Code: Select all

make -j4

Code: Select all

sudo make modules_install

Code: Select all

sudo make install

Output from that is

When installing VB 6.0

Code: Select all

This system is currently not set up to build kernel modules.
Please install the Linux kernel "header" files matching the current kernel
for adding new hardware support to the system.

Removed 5.0.4, and installed the headers for 4.20.12, and success. Now I only need the sources for that kernel, so I can use my own .config. :)

Thank you :)

Code: Select all

sudo make install

didn't work with 4.19 and VB-6.0, but after I upgraded to 6.0.4 it did.

Messed around so much now that I will have to reinstall tomorrow. :)
