Linux kernel github9/17/2023 ![]() Steve Rostedt uses make_min_config to get a truly minimum config, but it will take a day or two to build. For people wanting to do kernel development fast, you want to make a minimal configuration. Run make defconfigĬompiling a kernel from scratch from a distribution configuration can take "forever" because the distros turn on every hardware configuration possible. Remember, a default config may not have the options you are currently using. Or just run this command: cp /boot/config-`uname -r`*. Copy that file into the source directory as. You can find that by running uname -a and finding the config file that ends with your kernel version number. There might be several files that start with config, so you want the one associated with your running kernel. That config file is stored somewhere in /boot/. If you're trying to see if a bug is fixed, you probably want to duplicate the configuration on your running kernel. The easiest is to duplicate your current config. You have several options on generating a. When you download the source tree, it doesn't come with a. config file in the kernel source directory determines which drivers are built. Many kernel drivers can be turned on or off, or built as modules. Where tag is the latest vX.Y.Z tag you found.Ĭheck out Linus' tree: git clone git:///pub/scm/linux/kernel/git/torvalds/linux.git Now checkout the code associated with that kernel with the command git checkout -b stable tag The kernel tags that end with -rcX are release candidate kernels, not stable kernels. If v3.1.1 is available, use that instead of v3.1. For example, use the v3.1 tag over the v3.0.46 tag. Next, find the latest stable kernel tag by running git tag -l | lessįind the latest stable kernel by looking for the largest vX.Y.Z values. Git clone git:///pub/scm/linux/kernel/git/stable/linux-stable.git If you don't understand what a stable or release candidate kernel is, you should read the KernelDevProcess page.įirst, checkout the stable kernel git repository: Most subsystem maintainers keep their git trees on. If you're doing development for a new feature, or trying to test a bug fix, you should use Linus' tree, or the subsystem maintainer's -next tree. You should use the git URL they gave you instead of the git URLs below. Sometimes the maintainer may want you to use an experimental branch from their own git tree. If you are brave and your system is backed up the latest release candidate from Linus's tree is a great target. If you want to test to see if a bug is fixed then test against the latest stable kernel from. On Red Hat based systems like Fedora, Scientific Linux, and CentOS you can run: sudo yum install gcc make git ctags ncurses-devel openssl-develĪnd on SUSE based systems (like SLES and Leap), you can run: sudo zypper in git gcc ncurses-devel libopenssl-devel ctags cscope On Ubuntu, you can get these tools by running: sudo apt-get install libncurses5-dev gcc make git exuberant-ctags bc libssl-dev The ncurses-dev tools are used if you "make menuconfig" or "make nconfig". The tool packages may be called something else in your Linux distribution, so you may need to search for the package. ![]() To build the Linux kernel from source, you need several tools: git, make, gcc, libssl-dev and (optionally) ctags, cscope, and/or ncurses-dev. You can either download the full source code as a tar ball (not recommended and will take forever to download), or you can check out the code from the read-only git repositories. The latest source code for the Linux kernel is kept on.
