== Preface ==
+
This document tries to describe the process which let me successfully build Arch Linux under other architectures.
+
 
+
== Requirements ==
+
* A faster PC with Arch Linux already installed, we'll use it to build packages for i586.
+
* free disk space about 2G bytes.
+
: (space reqirement might grow to 4GB for a core repository per the begin of 2009)
+
* enough time, experience and temper prepared for fixing any problem encountered during the long long build
+
: (the core repository might take two days to build, excluding those failed, on a 2GHz E5405)
+
 
+
== Step 1. Prepare build enviroment ==
+
Prepare your system for build tasks as described in [[Makepkg#Setting Things Up]] :
+
pacman -S base-devel abs
+
Check /etc/abs.conf for activated repos, you should have at least core activated, check out or update
+
your abs tree. Then create an work directory for your i586 PKGBUILDs and duplicate repos into it.
+
# abs
+
# mkdir -p /home/i586/abs
+
# cd /home/i586/abs
+
# cp -r /var/abs/core .
+
: (in order to avoid building packages as root, it is better to customize specific ~/.abs.conf and ~/.makepkg.conf instead of system-wide /etc/abs.conf and /etc/makepkg.conf)
+
You also should create an directory where you will put the packages.
+
# mkdir -p /home/i586/pkg
+
Edit the /etc/makepkg.conf or copy to ~/.makepkg.conf , modify the following lines, we'll use -mtune option for x86 can also use the binary packages.
+
CARCH="i586"
+
CHOST="i586-pc-linux-gnu"
+
CFLAGS="-mtune=i586 -O2 -pipe"
+
CXXFLAGS="-mtune=i586 -O2 -pipe"
+
For faster compiling take a look on ccache and/or distcc.
+
 
+
== Step 2. Build packages ==
+
After we have prepared our build enviroment now is the time to run some last commands and get some coffee. Change to your
+
i586 abs directory and run makeworld.
+
# cd /home/i586/abs
+
# makeworld --clean --ignorearch --syncdeps --rmdeps --noconfirm /home/i586/pkg/core/ core/
+
When you didn't want to repeat typing your root pw for resolving dependencies you could
+
allow your build user to use pacman without retyping pw. See [[Disable root password and gain su sudo with no password]] for more information.
+
: (sudo is designed with security concerns, environs are stripped during sessions; so for those have only proxied access to the internet, it is better to expicitly allow passing environs like http_proxy/ftp_proxy/RSYNC_PROXY etc in /etc/sudoer)
+
And do not forget to deactivate it after using for building process!
+
 
+
== Step 3. Solve Problem during Compiling ==
+
After the build Process come to an end, we should check which packages have problems while building.
+
# grep failed build.log
+
Then you should change to the package directorys in your abs copy and retry building it.
+
# cd core/<failed package>
+
# PKGDEST=/home/i586/pkg/core/ makepkg --clean --ignorearch --syncdeps --rmdeps
+
For more information about building packages see in [[makepkg]]
+
 
+
== Step 4. Share Built Packages for i586 ==
+
Set up a [[Custom local repository]] for sharing your packages with the target system.
+
 
+
== Step 5. Install Arch Linux on i586 by bootable linux ==
+
See [[Install Arch from within another distro]], and use your custom repos as package source.
+
