BBCLASSEXTEND="native nativesdk"

Question

After checked the official document, I still don’t understand this meaning in recipe.

BBCLASSEXTEND="native nativesdk"

Install

It allows a normal recipe to be extended to a native recipe (and can be included in a host part SDK). – Telescopy

Answer 1

BBCLASSEXTEND is a way for the named classes (in this case, native and nativesdk) to run over the recipe to alter them.

The native class makes a version of the recipe (with -native appended to the name) that builds for the build host instead of the build target, so you can execute the binaries during the build. The nativesdk class is similar but builds packages to be executed in the SDK.

Exaggerative

Does that mean that I set BBCLASSEXTEND = "" if my recipe is only meant to be built for the target machine architecture? – Eurystheus

In that case, don't set BBCLASSEXTEND (which is the same as setting to ""). – Exaggerative
