In order to build the kernel module, you need to install the kernel-headers package corresponding to kernel version.
-
For ubuntu:
apt-get install build-essential linux-headers-`uname -r`
We use Makefile to manage the build flow.
-
Build the kernel module:
make
-
Load kernel module on local machine
sudo insmod yark.ko
-
Uninstall kernel module
sudo rmmod yark
-
Clean up
make clean
For developers using vscode, in order for vscode to know the kernel header files path, it is recommended to create a configuration file .vscode/c_cpp_properties.json that contains the following:
{
"env": {
"kernel_release": "<your kernel version>"
},
"configurations": [
{
"name": "Linux",
"defines": [
"__GNUC__",
"__KERNEL__"
],
"includePath": [
"${workspaceFolder}/**",
"/lib/modules/${env:kernel_release}/build/include",
"/usr/lib/modules/${env:kernel_release}/build/arch/x86/include/asm",
"/usr/lib/modules/${env:kernel_release}/build/arch/x86/include",
"/usr/lib/modules/${env:kernel_release}/build/arch/x86/include/generated",
"/usr/lib/modules/${env:kernel_release}/build/include/uapi"
]
}
],
"version": 4
}Remember to change the value of
kernel_releaseto the version of your kernel. You can query your kernel version withuname -r.
