3.32. How to install the kernel header file

The Debian 11 system with the Linux6.1 kernel will report a GCC error when compiling the kernel module. So if you want to compile the kernel module, please use Debian12 or Ubuntu22.04

1) The Linux image released by OPi comes with the deb package of the kernel header file by default, and the storage location is /opt/

orangepi@orangepi:~$ ls /opt/linux-headers*
/opt/linux-headers-xxx-sun50iw9_x.x.x_arm64.deb

2) Use the following command to install the deb package of the kernel header file

orangepi@orangepi:~$ sudo dpkg -i /opt/linux-headers*.deb

3) After installation, you can see the folder where the kernel header files are located under /usr/src

orangepi@orangepi:~$ ls /usr/src
linux-headers-x.x.x

4) Then you can compile the source code of the hello kernel module that comes with the Linux image. The source code of the hello module is in /usr/src/hello. After entering this directory, use the make command to compile

orangepi@orangepi:~$ cd /usr/src/hello/
orangepi@orangepi:/usr/src/hello$ sudo make
make -C /lib/modules/5.4.125/build M=/usr/src/hello modules
make[ 1]: Entering directory '/usr/src/linux-headers-5.4.125'
CC [M] /usr/src/hello/hello.o
Building modules, stage 2.
MODPOST 1 modules
CC [M] /usr/src/hello/hello.mod.o
LD [M] /usr/src/hello/hello.ko
make[ 1]: Leaving directory '/usr/src/linux-headers-5.4.125'

5) After compiling, the hello.ko kernel module will be generated

orangepi@orangepi:/usr/src/hello$ ls *.ko
hello.ko

6) Using the insmod command, you can insert the hello.ko kernel module into the kernel

orangepi@orangepi:/usr/src/hello$ sudo insmod hello.ko

7) Then use the demsg command to view the output of the hello.ko kernel module. If you can see the output instructions below, the hello.ko kernel module is loaded correctly

orangepi@orangepi:/usr/src/hello$ dmesg | grep "Hello"
[ 2871.893988] Hello Orange Pi -- init

8) Use the rmmod command to uninstall the hello.ko kernel module

orangepi@orangepi:/usr/src/hello$ sudo rmmod hello
orangepi@orangepi:/usr/src/hello$ dmesg | grep "Hello"
[ 2871.893988] Hello Orange Pi -- init
[ 3173.800892] Hello Orange Pi -- exit
