Can not build external kernel module about linux HOT 9 OPEN

Did you install the linux headers:

sudo apt install linux-headers-`uname -r`

Hi,
Ofcourse.
I installed my new build:
linux-image-5.4.106_5.4.106-1_armhf.deb
linux-headers-5.4.106_5.4.106-1_armhf.deb
linux-libc-dev_5.4.106-1_armhf.deb

from linux.

linux-image-5.4.106_5.4.106-1_armhf.deb
linux-headers-5.4.106_5.4.106-1_armhf.deb
linux-libc-dev_5.4.106-1_armhf.deb

Those aren't mine.. Did you build nativity or cross built the *.deb files?

Did you build nativity or cross built the *.deb files?

This is my natively build of the newest RT kernel.
Linux beaglebone 5.4.106 #1 SMP PREEMPT_RT Sat Sep 18 22:16:51 CEST 2021 armv7l GNU/Linux
I took about 20h on my BBB

from linux.

I've build kernel on my BBB many times before (last time 9 months ago) and had no trouble building the external module afterwards. For example:

git clone -b 5.4-rt --depth 1  https://github.com/beagleboard/linux
cd linux
sudo make bindeb-pkg

It looks like some headers files are missing now in linux-headers-5.4.xxxxxx_armhf.deb.

Was there any progress regarding this problem?

I use the BBG and came from kernel 4.19 and updated to 5.4 but my kernel module is now failing with the same error as mentioned above:

make[3]: *** No rule to make target 'arch/arm/kernel/module.lds'

I used the kernel_update.sh from https://github.com/RobertCNelson/boot-scripts and installed headers afterwards, as well as "apt dist-upgrade".

Current uname: linux-kernel-5.4.106-ti-r40 and -r39

small addition:

• testing with kernels between 5.4.52-ti-r17 and 5.4.106-ti-r36 showed another error earlier in the build process of the kernel module

CC [M] /opt/shepherd/software/kernel-module/src/pru_comm.o /tmp/ccp9lSUA.s: Assembler messages: /tmp/ccp9lSUA.s:43: Error: selected processor does not support "dsb st" in ARM mode /tmp/ccp9lSUA.s:231: Error: selected processor does not support "dsb " in ARM mode

• testing with kernels up to 5.4.182-bone64 (newest) showed the error mentioned above.

i'm facing similar issue with 5.x kernel
i have take a look of many linux-headers-5.*_1buster_armhf.deb and all looks to be incomplete, Kconfig and many dirs are missing:

.# ls -1 /usr/src/linux-headers-5.10.131-ti-r49
Makefile
Module.symvers
arch
include
scripts

4.19 kernel looks good

from linux.

this is a change in 5.10.x that messed all this up..

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1906131

change KDIR..

odd because the same issue is in your kernel 5.4.x
maybe it is a different issue (I can open a new bug if u prefer), but definitely your 5.4.x and 5.10.x kernel headers are incomplete

.#ls usr/src/linux-headers-5.4.106-ti-r41
Makefile Module.symvers arch include scripts

.#ls usr/src/linux-headers-5.10.131-ti-r49
Makefile Module.symvers arch include scripts

. # ls /usr/src/linux-headers-4.19.94-ti-r73/
Documentation Makefile arch certs drivers fs init kernel mm samples security tools virt
Kconfig Module.symvers block crypto firmware include ipc lib net scripts sound usr

.#ls /usr/src/linux-headers-5.15.48-sunxi64
arch certs Documentation fs init Kconfig lib mm net scripts sound usr
block crypto drivers include ipc kernel Makefile Module.symvers samples security tools virt

last one come from another system, but just to show about things are not changed in newer kernel (been using the same wifi driver on both system)
