How to find the custom recipe created in yocto inside my embedded linux image

Question

I created a st-image-qt image using the STM32MP Distribution package and X-LINUX-QT add-on for the STM32MP157F-DK2 board.

I could flash this image using the dd command in Linux and my target board is running correctly.

On the other side, I created a qt quick app using qt 6.7.3(which I could test ok using qt creator) and now I need to add this qt app in my st-image-qt image. I can bitbake this custom recipe doing "bitbake mygui"

I created the custom layer and a custom recipe and added this custom layer to my bblayers. Then, I built the image again with this custom recipe and it worked ok.

The problem is that I'm expecting to find this qt app inside my bin directory, but I can't see it.

inherit cmake_qt5

In my local conf file I added: IMAGE_INSTALL_APPEND += "mygui"

Answer 1

Adding IMAGE_INSTALL_APPENDin the local conf seems to be the problem.

Try to add the recipe to the image you are building. In one of the layers there should be a st-image-qt.bb file. It should be in <layername>/recipes-core/images. There, you have to add it with IMAGE_INSTALL:append = " mygui " (Note the space after the "). Only then the recipe is included in the image, only adding the layer is not enough.

Note that this is not a very pretty solution. You should create your own image.bb file in your own layer, and add your application there.
