  1. Compiling the Minix3 Kernel Karthick Jayaraman

  2. Compiling everything • cd /usr/src. • make world. • “make world” automatically creates a boot image. (What is a boot image ?). • Note down the name of the boot image.

  3. Compiling everything

  4. Compiling everything

  5. Booting up using the new kernel • After compiling, you may use the “shutdown”. • After shutdown, you would see the Boot manager’s prompt. • At the prompt, you may issue “ls /boot/image” to list all the images. • You may set the new compiled image using the command “image = /boot/image/3.1.2ar52”. • Finally, you may issue “boot”.

  6. Booting up using the new kernel

  7. Compiling the FS Server • Compiling “world” is not required every time. • Changes often affect one directory in /usr/src/. • Compile only the affected component • Build a boot-image.

  8. Compiling the FS Server • Go to /usr/src/servers/ • fs is part of servers. Changing any of the servers requires compiling and installing servers. • fs source code is available at /usr/src/servers/fs.

  9. Compiling FS Server • cd /usr/src/servers/ • Issue “make build” • Issue “make install” • Cd /usr/src/tools/ • Issue “make hdboot”

  10. Compiling the Libraries • Source code at /usr/src/lib • After making source code changes, issue “make” in the /usr/src/lib directory. • Go to /usr/src/ • Issue “make libraries”. • Go to /usr/src/tools • Issue “make hdboot”

  11. Boot Images • Always have one stable boot-image in the /boot/image directory. • You could use that boot-image, when you current changes throw a kernel-panic.
