Pi3 running Archlinux setup instructions.

[jrlambs]

I just got done starting from a fresh ArchLinuxArm install and documenting my steps.

Thanks to @maso27 for the information I used and to @illperipherals for helping me through some of the issues.

Followed instructions to create a file system for arch from: https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-3 (Installation Tab)
From initial bootup:

AS ROOT

pacman -S sudo
nano /etc/sudoers

Add the following lines

alarm   ALL=(ALL) ALL
Defaults:alarm      !authenticate

pacman -S python2
pacman -S python2-pip
pacman -S python2-virtualenv
pacman -S git
pacman -S vox
pacman -S gcc

cd /usr/bin

ln -sf python2 python
ln -sf pip2 pip
ln -sf virtualenv2 virtualenv

#Follow maso27's instructions

#"apt-get update" => "pacman -Sy"
#"apt-get install xxxx -y" => "pacman -S xxxx --noconfirm"
#"python-dev" => "python2"
#"libasound2-dev" => "alsa-lib" and "alsa-utils"
#"libpulse-dev" => "libpulse"
#"python-yaml" => "python2-yaml"
#remove "python-alsaaudio"
#add "RPi.GPIO>=0.6.2" to requirements.txt link to updated file
#add "dtparam=audio=on" to /boot/config.txt
#shairport-sync is already a package in archlinux repos, so just "pacman -S shairport-sync --noconfirm" to replace most of the build steps there.

.. I'll attach the new script.

At this point I had an issue with the line below... I installed each item on its own.

1. When I got to VLC I was asked 2 questions. I selected option "1", the default option, for both.
2. obviously when I got to python-yaml I needed to change it to python2-yaml.. that might have been the whole issue.. now that all of the things are installed I can run that pacman command no problem... so it may or may not be an issue
   pacman -S swig alsa-lib alsa-utils memcached vlc libpulse gcc python-yaml --noconfirm

#So at this point I the script finished successfully
#Follow maso27's other set of instructions from running as user/group alexapi

groupadd gpio -r
usermod -a -G gpio alexapi
nano /etc/udev/rules.d/99-gpio.rules

#Insert the following (3 lines):

SUBSYSTEM=="bcm2835-gpiomem", KERNEL=="gpiomem", GROUP="gpio", MODE="0660"
SUBSYSTEM=="gpio", KERNEL=="gpiochip*", ACTION=="add", PROGRAM="/bin/sh -c 'chown root:gpio /sys/class/gpio/export /sys/class/gpio/unexport ; chmod 220 /sys/class/gpio/export /sys/class/gpio/unexport'"
SUBSYSTEM=="gpio", KERNEL=="gpio*", ACTION=="add", PROGRAM="/bin/sh -c 'chown root:gpio /sys%p/active_low /sys%p/direction /sys%p/edge /sys%p/value ; chmod 660 /sys%p/active_low /sys%p/direction /sys%p/edge /sys%p/value'"

Reboot.... it's working.. all audio is coming through the onboard sound card instead of the USB one.. will work on that later.

We'll add this to this setup script once things are calm elsewhere :)

What do you need the sudo(ers) stuff for? You don't need that for AlexaPi.

You can set your output device / card in config.yaml.

[jrlambs]

Yeah, you don't. I went back to retrace my steps after I had everything working and for some reason decided to put that in my writeup.. don't know why. def don't need the sudo stuff for the purposes of AlexaPi

[renekliment]

Also, please paste any small changes here in a code block and bigger changes / files as gists so people don't have to download stuff just to see and they can comment, edit, share, whatever.

[jrlambs]

Ah, no problem.. I've updated the links to point to gists, wasn't sure the correct way to do that before... still not positive I did it right.. but it's better than it was

[renekliment]

Great!

#82 should include all needed steps. Could you test?
