Compile Time Indication of Zephyr Build Version for Conditional Compilation

[bob2oneil]

The most recent release of Zephyr changed some of the content associated with the Flash file system such that an include file (as #include <fs/littlefs.h>) no longer exists.

But this question is about what is the proper procedure for having conditional compilation in a source file so that it is backwards compatible with perhaps less recent versions of Zephyr for team members frozen to an older tested version?

I would like the source code to handle these types of changes gracefully.

In the Zephyr source file VERSION, there are differences.

I can include #include <kernel_version.h> in my source and key off of say the KERNEL_VERSION_ content?
