This document describes all the steps to cross compile vlc for ARM based
platforms. It describes how to build a cross compilation toolchain, how to
I will describe here how to compile vlc for an ARM based
PDA running linux. It includes for example :

+ <heading>Setting up Opie cross-compile environment</heading>
+ <p>Download the Opie SDK from the website <htmlurl url="http://opie.handhelds.org/" name="OPIE website">
+using the menuitem "Download Opie SDK" or try the direct link here: <htmlurl url="ftp://ftp.handhelds.org/zecke/" name="Download Opie SDK">.
+Download all files to your ${SOURCES}/opie directory.
+ </p>
+ <sect1>
+ <heading>Opie SDK</heading>
+ <p>The Opie SDK does not come with a README file or installation instructions.
+I give them here instead. There are two tar files in the download a OpieSDK.tar.gz2 and a kdevelop_src.tar.bz2.
+The last file is a modified kdevelop for use with the OpieSDK. In this tutorial we will not use that.
+Unpack OpieSDK.tar.bz2 in your sources <tt>cd ${SOURCES}/opie</tt> directory.
+ <tscreen><verb>
+cd ${SOURCES}/opie
+tar -xjvf OpieSdk.tar.bz2
+ </verb></tscreen>
+ It creates a directories structure <tt>${SOURCES}/opie/opt/OpieSDK</tt>. Inside that directory a script is present to
+<tt>start_kdevelop</tt>. Modify this script so that it uses the correct paths for you setup.
+ <tscreen><verb>
+#!/bin/sh
+source ${SOURCES}/opie/opt/OpieSdk/dev_env
+export KDEDIR=${SOURCES}/opie/opt/OpieSdk/kde
+export PATH=${SOURCES}/opie/opt/OpieSdk/kde/bin:$PATH
+kbuildsycoca
+kdevelop
+ </verb></tscreen>
+ Save the script. Do the same with the script <tt>arm_source</tt>
+ <tscreen><verb>
+source ${SOURCES}/opie/opt/OpieSdk/dev_env
+export QTDIR=$QTDIR_ARM
+export OPIEDIR=$OPIEDIR_ARM
+ </verb></tscreen>
+ Save the script and modify the script <tt>host_source</tt> in the same manner as above.
+ <tscreen><verb>
+source ${SOURCES}/opie/opt/OpieSdk/dev_env
+export QTDIR=$QTDIR_NAT
+export OPIEDIR=$OPIEDIR_NAT

+ The symbolic linke to the tool <tt>qmake</tt> points now to the wrong place. We need to fix this symbolic link.
+Here is the way to do that.

+cd host_tools
+ln -sf /home/jpsaman/src/opie/opt/OpieSdk/opie/x86/sdk/qmake/qmake qmake

+ Now it is time to fire up our development environment and start hacking in Opie.
