Use a yocto layer's recipe or class without inheriting all bbappends

I want to use a specific class of a given layer or maybe just a given recipe. But I don't want to use anything more, nor that my build gets affected by other bbappend's present in that layer.

What is the way to proceed?

My specific use case:

I am writting a recipe which is using qmake5 to build. Therefore I am interested in qmake5.bbclass. The software built in fact has no QT content, but just uses qmake. Therefore I am not interested in the rest of the meta-qt5 layer

Solution

  • You could mask all directories from meta-qt5 later except the classes dir. Add to you local.conf:

    BBMASK += "meta-qt5/recipes-*/"
