building pve kernel fails with make[2]: *** [debian/rules:281: abicheck] Fehler 1

[RolandK]

i'm reproducably getting this error when trying to build pve kernel from git. i'd like to try to test a btrfs patch.

does somebody know why this happens and how to resolve?

i spent quite a wile to figure it out, but i get no clue what's the problem.

i did proceed according to README:

1. installed all build dependencies

2. cd /build ; git clone git://git.proxmox.com/git/pve-kernel.git

3. cd /build/pve-kernel

4. make build-dir-fresh

5. mk-build-deps -ir pve-kernel/proxmox-kernel-7.0.2/debian/control

6. make deb

that runs for quite a while and then finally bails out reproducably with this error.

while running make build-dir-fresh, i see this weird error

cd proxmox-kernel-7.0.2; debian/rules debian/control

dpkg-buildapi looks related

Does the folder /build/pve-kernel/proxmox-kernel-7.0.2/debian/control/ actually exist?

Looking at 3 and 5 you might now have /build/pve-kernel/pve-kernel/proxmox-kernel-7.0.2/debian/control/

yes

>Looking at 3 and 5 you might now have /build/pve-kernel/pve-kernel/proxmox-kernel-7.0.2/debian/control/

sorry, posted the wrong path. i meant mk-build-deps -ir proxmox-kernel-7.0.2/debian/control

 

[Impact]

It's extremely jarring to read different languages within the same line. Please change your system language. At least temporarily.

 

[fabian]

if you change the kernel sources in a way that changes the ABI, you need to bump the ABI ("KREL" in Makefile and changelog bump), or disable those checks (SKIPABI env variable). the other warnings are benign - they are caused by d/control being a generated file, but d/rules sourcing some things that expect it to exist already.

 

[RolandK]

yes sure, but i did not yet change the kernel sources at all.

i'm getting the same error on debian12

now with language set to en_US

[fabian]

are you sure you are starting from a clean slate? what does "git status" say?

 

[fabian]

a clean checkout of current master (87f22e55de30d73b83722b86790394564036b33c) followed by `make clean deb` works fine here.
