Kernel Builder script -- simple version

[fulalas]

The idea is not to replace neko's application, but just to provide a straightforward non-UI approach that doesn't require updates when a new kernel is released.

Usage:

Code: Select all

./kernel.sh [kernelVersionYouWantToCompile]

Example:

Code: Select all

./kernel.sh 5.12.14

It will download the kernel source code, AUFS path for the given kernel version, firmware, compile everything and generate:

• vmlinuz

• 000-kernel.xzm

• 06-crippled_sources-[kernelVersion].xzm.

Typical output:

Code: Select all

Initial setup...
Downloading kernel source code...
Extracting kernel source code...
Copying .config file...
Downloading AUFS...
Patching AUFS...
Building kernel (this may take a while)...
Creating symlinks...
Downloading firmware...
Extracting firmware...
Adding firmware...
Blacklisting...
Copying cryptsetup...
Creating kernel xzm module...
Creating crippled xzm module...
Cleaning up...
All finished.

Files generated:
vmlinuz -> should go into boot/syslinux
000-kernel.xzm -> should go into porteus/base
06-crippled_sources-5.12.14.xzm -> should go into porteus/base

Tips:
1- If the script detects either the kernel source package or firmware package in the script folder it won't download them again.
2- All the temporary files will be created in /tmp/kernel-builder, and they should be deleted when the process finishes.
3- If you forget to run it as sudo it will ask for sudo pass.
4- You only need 3 files for this to work (they're all included in the package above):

• kernel.sh (of course)

• 64bit.config or 32bit.config (which contains kernel configuration)

• cryptsetup (for handling encrypted save changes)

It should be able to build any version of the kernel that is still buildable nowadays, either 32 or 64 bit. I haven't tested with many different kernel versions so I can't guarantee much. It's still very experimental and any feedback is welcome.

Next version should include a way to log the output -- at the moment the script is swallowing all the output for a cleaner experience.

I would like to thank neko for his generous patience to teach me all the tricks that involve building Linux kernel. He's the man!

It's failing to build (actually, link) 5.15.x with the following error:

Code: Select all

ld: fs/inode.o: in function `__ksymtab_update_time':
inode.c:(___ksymtab_gpl+update_time+0x0): undefined reference to `update_time'
ld: fs/aufs/i_op.o: in function `aufs_update_time':
i_op.c:(.text+0x19c): undefined reference to `update_time'
make: *** [Makefile:1183: vmlinux] Error 1

I reported the issue: https://github.com/sfjro/aufs5-standalone/issues/8

[beny]

hi,the issue of aufs patch is start with the 5.15.6 and also neko don't have the hint to solve this, but he have the overlay option,the 5.16-rc5 do not have issue with aufs, you can try to build it i have tried to download it via your script but no way... error

[roadie]

fulalas,

I just compiled the 5.15.8 kernel using the aufs5.15.5 patch.......no errors on patching and the kernel booted well.

https://github.com/sfjro/aufs5-standalone/branches

[beny]

hi i can confirm that aufs 5.15.5 work on 5.15.10 with roadie advice

[fulalas]

Yeah, confirmed. Working version now uploaded (first post).

In the future I'm going to add more specific verifications for these broken versions... Zzzzz

[fulalas]

Does anyone know why kernel is failing to build? No matter what version I'm trying, including 5.12.14 which I tested countless times during the development of this script!

That's the error output if I remove > /dev/null 2>&1 from the make olddefconfig command (line 88):

Code: Select all

  ...
  HOSTLD  scripts/kconfig/conf
make[1]: *** [scripts/kconfig/Makefile:63: olddefconfig] Segmentation fault
make: *** [Makefile:602: olddefconfig] Error 2

EDIT: never mind. It's something in our current developer base.

[UrUtusUbU]

in line 19 get i a error about a space,

code WITH ERROR

Code: Select all

	if [ ! -f 32bit.config]; then

code WITHOUT ERROR

Code: Select all

	if [ ! -f 32bit.config ]; then

ONLY put A SPACE AFTER config

Building kernel (this may take a while)...
iam building 5.15.8 at the moment no problems,
waiting the end...........

thanks

why use ausfs neither??

@UrUtusUbU, thanks for the bug report. It's fixed now (first post).

@all, kernel will fail to build if you use wrong combination of devel module and core/xorg modules. EDIT: it seems there's something in the new core module that is breaking kernel build. I still don't know what

[Ed_P]

@all, kernel will fail to build if you use wrong combination of devel module and core/xorg modules.

How does one know what devel mod goes with which core/xorg mods?

[Blaze]

Yep
