You can even gracefully test for CPU opcodes support, read e.g.
#How to find linux kernel version code#
Some code examples: dl = dlopen(module_path, RTLD_LAZY) įprintf(stderr, "Failed to open module: %s\n", module_path) įprintf(stderr, "Failed to find symbol: %s\n", module_function)
#How to find linux kernel version upgrade#
Note that the first way above applies even if your software is binary-only. Which version of Linux kernel am I using If it is 4.4.0, How can I upgrade it to 5.x If it is 5.10, how can I check to make sure that it is that version linux ubuntu windows-subsystem-for-linux wsl2 Share Improve this question Follow edited at 20:50 NotTheDr01ds 17. Unless you downloaded, compiled and installed your own version of kernel from, you are running a distribution kernel. As of the 2.6.18 kernel release, the 2.12 release of binutils is the oldest that can. It is easy to tell if you are running a distribution kernel. To determine which version of gcc you have on your system. To check the Linux Kernel version, you can use one of the following commands. configure check if applicable (standard FOSS way of automatically recognizing system features/properties) These kernel releases are not hosted at and kernel developers can provide no support for them. dlopen for libraries, syscall(2) for syscalls and so on) As per the above output, you’re running Linux kernel '4.18.0-477.13. uname (stands for UNIX name) that prints system information such as the host name, Linux kernel version and other details of the operating system on which it is running. try to use given features and fail gracefully (e.g. The uname command is a quick way to check the Linux kernel version.This command should work on all Linux distributions that have the lsb-release package installed: lsbrelease -a No LSB modules are available. does it support some syscall or does it have some library), instead of relying on output of lsb_release you should either: lsbrelease command The lsbrelease utility displays LSB (Linux Standard Base) information about the Linux distribution. If you're trying to detect some features or properties of the system (e.g. The Linux kernel is a free and open-source, monolithic, Unix-like operating system kernel.
What's the purpose of getting that information? This article documents the version history of the Linux kernel.
