在哪里可以找到 Linux kernel 源代码树的版本？

Question

I have downloaded from a hardware vendor just a tarball of their Linux source tree (no Git repository metadata), is there a way to find out the version number of the kernel?

Is the version number usually stored in a file somewhere in the source tree?

I'd like to be able to do this without compiling and running the kernel.

Answer 1

You can find the version by running

make kernelversion

In the source tree

Answer 2

Check the top-level Makefile , an example of which is here . At the top of that, you should see something like:

VERSION = 3
PATCHLEVEL = 1
SUBLEVEL = 0
EXTRAVERSION = -pax
NAME = Custom Pax Version

The (admittedly minor) advantage of this method is that you only need the ability to view the files themselves rather than having to run a build process.

Answer 3

另一个解决方案：在较早的时候include/linux/version.h ，当前是include/generated/uapi/linux/version.h ，但只有在至少部分成功编译之后。

Answer 4

In the kernel source tree, check the root directory Makefile to get the kernel version as below.

Example as below:

 $ head Makefile
 # SPDX-License-Identifier: GPL-2.0
 VERSION = 5
 PATCHLEVEL = 18
 SUBLEVEL = 0
 EXTRAVERSION = -rc3
 NAME = Superb Owl
 # *DOCUMENTATION*
 # To see a list of typical targets execute "make help"
 # More info can be located in ./README

From the above we get the source code version is 5.18.0-rc3

Answer 5

In the Linux source tree's root file, check the Makefile content. In its beginning part:

# SPDX-License-Identifier: GPL-2.0
VERSION = 4
PATCHLEVEL = 14
SUBLEVEL = 67

Then you linux source tree's version is: 4.14.67
