To be prepared to make changes to the kernel, it’s necessary to give it a try to compile the linux kernel successfully.
Environment
- VMware Fusion 7
- Ubuntu 12.04.5
- Root permission
Objective
Initially, the kernel version of the Ubuntu 12.04.5 is 3.13.0-32-generic according to
If you wanna check your ubuntu version, use
Our goal is to update the version of kernel to newer one, in this case, 3.18.
Compile the Linux Kernel
1. Download the kernel from here.
2. Copy to a directory and extract.
1 2 3 4 5
| cp linux-3.X.X.tar.xz /usr/src cd /usr/src xz -d linux-3.X.X.tar.xz tar -xf linux-3.X.X.tar cd linux-3.X.X
|
3. If not the first time to compile
1 2
| make clean make mrproper
|
4. Configuration
There might be a tiny prob here saying
1
| fatal error: curses.h: No such file or directory
|
Solution under Ubuntu:
1
| sudo apt-get install libncurses5-dev libncursesw5-dev
|
5. Compile
1 2 3
| make make modules_install make install
|
Suggestion here: enlarge the memory size of your virtual system, which may help reduce the compiling time dramatically.
It takes hours to compile with 1 core and 1-GB memory with GUI turned on…
6. Update GRUB
1 2 3 4 5
| cd /boot mkinitramfs 3.18.8 -o initrd.img-3.18.8 cp /usr/src/linux-3.18.8/arch/x86_64/boot/bzImage /boot/vmlinuz-3.18.8 ln -s /boot/System.map-3.18.8 /boot/System.map sudo update-grub2
|
7. Reboot and Check!
