 ===== Installing ikiwiki ===== ===== 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>

 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. 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]].
