[Librem-5-dev] Building for arm

[Maxim Linkov]

Hello, everybody!

My name is Maxim Linkov, I'm trying to build phosh for armhf (my portable Raspberry Pi) but unable to register to ask questions. To be honest, there is a lack of info :(

First I was trying to upgrade my Raspbian to Buster, but it is always broken after update, so I've stopped on installing Ubuntu Mate [arm] and upgrading it to 18.04 (bionical) and adding Debian testing repo to acquire necessary fresh libraries.
Aftrer building libhandy, I got to manually check dependencies to add missing and got this list (not sure, mb something exessive a little bit):

libupower-glib-dev ctags libwayland-server0 libwayland-dev
wayland-protocols libcogl-gles2-dev libgles2  libgles2-mesa-dev libinput-dev libinput-bin                     
libsystemd-dev libavutil-dev libcap-dev libcap2-dev libcap-ng-dev libavutil55 libcap-ng0
libavcodec-dev libavcodec58 libavformat58 libavformat-dev libavutil-dev libavutil56
libxcb-xkb-dev libxcb-composite0-dev libxcb-composite0 libxcb-xkb1 libxcb-icccm4-dev libxcb-icccm4
xcb-proto libxcb-image0-dev libxcb-image0

(it is still doesn't include "elogind" and "Dependency xcb-errors found: NO (tried pkgconfig)" which I was unable to find)


After that waste of time, I was able to build and install "phosh" (it was stand-alone install under /usr/local/bin/phosh)
And to build wlroots. "ninja -C _build install" only installs a set of header files to /usr/local/include/wlr so I've created a link to rootston at /usr/bin
After enabling the experimental desktop GL driver [GL (Full KMS)] in my raspi-config, I am finally able to run "rootston -E phosh".
I haven't found anything usefull for me in phosh/data/rootston.ini file (resolution works fine and I plan using it w/o keyboard and hotkeys), so I omit it...
When I start rootston from tty, it shows me only grey screen with mouse cursor and nothing else.
But it starts succesfully under my Mate x-session. I'm ok with it, because want to be able to use my main enveronment, but have a few questions.

1) When I run phosh, I can only see an empty desktop with 2 panels. When I click on the bottom panel - there is empty "Running Apps list" and Terminal in Favorites which I can't actually run ("phosh-favorites-WARNING: Couldn't launch terminal"). How can I add my own apps there?

2) When staying idle or by manually clicking "Lock screen" on upper panel, I need to enter Unlocking PIN. I haven't added any pin, how can I change it? (any config file?)

3) I've seen video on youtube (https://www.youtube.com/watch?v=vxwspcmgVF4) with set of apps and more complete experience. What additional packages do I need to get? Should I compile everything the way like I did before, or maybe there is a more suitable way?

4) I want to run it from my usuall user and doesn't have any  system.d service, should I create some config file somewhere?
