Question: How to Compile Linux Kernal?

The procedure to build (compile) and install the latest Linux kernel from source is as follows:

• Grab the latest kernel from kernel.org.
• Verify kernel.
• Untar the kernel tarball.
• Copy existing Linux kernel config file.
• Compile and build Linux kernel 5.1.2.
• Install Linux kernel and modules (drivers)
• Update Grub configuration.

To compile the kernel and its modules, we use the make command. This is followed by using make modules_install to install the kernel modules. Finally, we use make install to copy the kernel and the .config file to the /boot folder and to generate the system.map file (which is a symbol table used by the kernel).Install directly onto the SD card. Having built the kernel, you need to copy it onto your Raspberry Pi and install the modules; this is best done directly using an SD card reader. with sdb1 being the FAT (boot) partition, and sdb2 being the ext4 filesystem (root) partition.Also required is the Mac OS X SDK installed from your XCode CD or Mac OS X DVD.

• First, obtain the necessary files.
• Install the cross-compilers in /opt.
• Create and mount a disk image.
• Install gawk.
• Download sources.
• Patch sources.
• Set PATH variable.
• Compile.

How do I compile and install a new Linux kernel?

Configure, build, and install

1. Download the latest kernel from kernel.org. The kernel comes as a 20 to 30 MB tar.gz or tar.bz2 file.
2. Configure the kernel options.
3. Make dependencies.
4. Make the kernel.
5. Make the modules.
6. Install the modules.
