 Some random notes related to [[http://archlinuxarm.org|Arch Linux ARM]] on a Raspberry Pi. Some of these notes might be turned into their own page one day.
-===== Compiling Blender =====
+===== Blender =====
+==== Installing from packages on RPi3 ====
+[[https://archlinuxarm.org/packages/aarch64/blender|Blender is compiled for ARMv8 architecture only for AArch64]].
+See bottom of this page for the right archive to use at installation: https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-3#installation
+==== Compiling on RPi2 ====
 If it's still not in the repositories, here's a way to compile latest stable Blender for RPi2

 ===== Installing ikiwiki =====
-  * Install Git
+Install git and dev tools.
-  * Install Make
+<code>
-  * <del><code=bash>$: cpan</code></del>
+$: sudo pacman -Syu git base-devel
-  * Use Pacman with this[[https://aur.archlinux.org/packages/ikiwiki/| Aur package]]
+</code>
+Install [[https://aur.archlinux.org/packages/ikiwiki/| ikiwiki from Aur package]].
+You'll need 2 extra dependencies from Aur:
+  * [[https://aur.archlinux.org/packages/perl-cgi-formbuilder/ | perl-cgi-formbuilder]]
+  * [[https://aur.archlinux.org/packages/perl-rpc-xml/ | perl-rpc-xml]].
+Install those first. Compiling ikiwiki takes a while on a Raspberry Pi. Be patient.
+If you want to have images handle by the wiki, you will need also Imagemagick
+Although ikiwiki could be running from any server, I found it easier to run it behind Apache. So be sure to have that installed.
+Create an unprivileged user (here called wiki) who will be editing the wiki:
+<code>
+sudo useradd -m wiki
+sudo passwd wiki
+</code>
+Following https://www.linode.com/docs/websites/wikis/ikiwiki-on-arch-linux/
 ===== Resizing a partition =====
@@ Line 97: / Line 122: @@
 By resizing (which is safe to run on a mounted disk), we tell the file system to use all the space in the new partition.
+===== Python UnicodeEncodeError horror =====
+So your Python script works on your machine. But when you port it to a freshly installed Arch Linux Arm on a Pi, all hell breaks loose as soon as a weird character pops up. Something like this shows up:
+<code>UnicodeEncodeError: 'ascii' codec can't encode character '\xe9' in position 227: ordinal not in range(128)</code>
+Well, don't start modifying your Python code (as you said, it does not have that problem on your machine).  It's because the default locale of Arch Linux is ''LANG-C'' and what you want is UTF-8 support. There is many ways to solve this, including forcing Python to use a locale different from the system. But I like to have my systems with similar settings. So just follow tutorials [[https://wiki.archlinux.org/index.php/Locale|here]].
