===== Missing build directory =====
<code>make[1]: *** /lib/modules/[version]/build: No such file or directory. Stop.</code>
The cmd <code>sudo apt install raspberrypi-kernel-headers</code> will simply install the latest kernel headers available on the mirror. Which indeed matches the latest available kernel on the mirror. But not necessarily the installed kernel on the system.
The Raspbian maintainers always remove the older kernel headers from the repository index files. Not sure why they do that.
Solutions：
1. Upgrade piOS, and build again.
<code>apt install raspberrypi-kernel raspberrypi-kernel-headers</code>
2. Install specific version kernel headers.
