Yocto Recipe for Building QT5 App

kengineer

Is this something normally done with Yocto? I noticed that demo QT5 recipe apps contained in both the meta-qt5 layer and from my SOC vendor's bsp layer seem to simply pull tarballs/archives of the built application down from a remote repo rather than pulling any source and building it.

Yocto actually has a wiki article regarding building qt4 apps but I haven't seen anything anywhere about building qt5 from source with Yocto/bitbake:
https://wiki.yoctoproject.org/wiki/Creating_a_recipe_for_a_Qt_application

Actually after examining it closer, it looks like maybe I was mistaken that they are being built. The recipes are relying on inheriting the "qmake5" class via "inherit qmake5."

Using this demo application:

I have this example recipe, which I use to validate Yocto Project images with Qt5.
