[meta-qt5] Do_install_append() with qmake

[meta-qt5] Do_install_append() with qmake

Hello all,

I hope you'll be able to help clear some things up for me.

I have created a recipe to build and install a Qt Application I've been
developing, so far everything has been working great and the program gets
compiled, installed and packaged.

However there is one additional install step I need to complete, which is
creating a symbolic link to my binary in /opt to /usr/bin/b2qt. I want to
do this so that the Boot2Qt appcontroller starts my application on boot.

There are two ways I thought I could do this.
1. Use do_install_append() in the recipe to create the symbolic link.
However qmake5.bbclass does not export the do_install function. Modifying
the .bbclass with EXPORT_FUNCTIONS do_install breaks everything so I think
that this is the wrong way to go about it.

2. Use target.extra in the qmake .pro file to add the extra commands.
This one I had a bit more success with, I added my commands to target.extra
and built the recipe.
In this case do_install appeared to run properly. I could see my symbolic
link in the image directory however the binary that was complied no longer
appears in the image directory. So I've fixed one thing and broke another.

At this point I've reached the end of what I think I can try, I'm sure I'm
missing something simple since extra install steps are a common task. Can
someone tell me what the canonically correct way that I should be doing
this is?

I've attached my recipe and a segment of my .pro if that helps.

Best Regards,
Dylan Bartlett

Maybe IMAGE_POSTPROCESS_COMMAND might help?
https://www.yoctoproject.org/docs/2.5/ref-manual/ref-manual.html#var-IMAGE_POSTPROCESS_COMMAND

There's an example of using it in:

Sorry all, ignore this. Do_install_append works, from what I can only call
a formatting issue in my recipe seems to have stopped the _append from
running.

Fixing some of the formatting in my _append function seems to have started
things working.

My next issue seems to be that my application is building in a debug
configuration and the linker is producing a pretty large binary (~150MB).
But I haven't exhausted myself on that issue yet.

Thanks for taking the time to reply even though this is my own fault,
Dylan
