7.5. Compile the Kernel Module

Try these first

1. 1.

   What is the purpose of a Makefile?

   Hint

   Think about automation and script files.

2. 2.

   What command do you run to start the compilation of kernel modules?

3. 3.

   What is the command to compile the kernel module?

   • False

   Hint

   Think about what context 'obj-m' is relevant to.

5. 5.

   You have multiple source files in your project: sensor.c, utils.c, and config.c. Modify the Makefile to properly compile these into a kernel module.

   Hint

   Consider how you would add more than one module.

6. 6.

   Your kernel module compiled successfully, but you face a runtime issue. Outline steps to troubleshoot and fix the problems.
