11/2/2023 0 Comments Check kernel version linux![]() ![]() What you'll probably have to do is determine exactly where the compressed data starts (sorry, can't help you there, but trial and error might work), and write a bit of code to run it through the library for whichever compression algorithm is in use. Traditionally, the compression algorithm was zlib (contrary to popular misconception, 'bzImage' did not stand for "bzipped image", but for "big zImage" - the original zImage format not being able to handle large kernels), though versions after 2.6.30 also support bzip2 and LZMA.

It actually consists of an ELF header and some other minutia (like a bit of decompression code) followed by, yes, a compressed image of the actual kernel. This is a preview of a SAP Knowledge Base Article. More accurate is probably utsname.version, but there is even more foo in it making parsing difficult (i.e. Modern Linux kernel versions use a format called bzImage (for x86/x86_64, YMMV on other platforms). 1 you can try to parse it with sscanf, but be aware, that there may be non-numeric extensions to the release (i.e. Shell script to verify the version of make on linux. How can I determine the Linux kernel version that a kernel object file was compiled against 0. Here’s what each of these numbers mean: 5 Kernel version. uname -srm Linux 5.8.0-44-generic x8664 The output shows us that we’re running kernel version 5.8.0-44. You will see the kernel version from the command output If you want to see more information about your kernel, type uname -a and press Enter. How can I check my kernel version in my Makefile Based on the kernel version I want to select some of the header files accordingly. Open a terminal and execute the following command to see yours. ![]() The output above tells us that the Linux kernel is 64-bit, and its version is 4. To find out what version of the Linux kernel is running on your system, type the following command: uname -srm. It's theoretically possible, but not entirely trivial. Procedures to check kernel version in Linux Open the terminal. The uname command displays several system information, including the Linux kernel architecture, name, version, and release. strings uImage | grep 2.6 ought to be good enough for any 2.6 kernel which covers pretty much everything in the last 5+ years). I just realized, the kernels I have immediate access to do have the version string stored uncompressed amongst the headers. ![]()
