How to cross-compile Xuggle-Xuggler for Windows 7 64 or 32 bit

Compile Xuggle-Xuggler on Ubuntu 11.10 64 or 32 on VirtualBox VM running over Windows 7 64 or 32 bit.

I’ve tested this process on a Windows 7 64 bit machine with a VirtualBox VM where I’ve installed two copies of Ubuntu 11.10 (one 64 bit and the other 32 bit).

Add required packages for compilation:

Java JDK:

sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin

Select Oracle Hotspot VM:

sudo update-alternatives --config java

Confirm that you are using Hotspot VM with:

java -version

Compiler and other dev tools:

sudo apt-get install build-essential

Yasm:

sudo apt-get install yasm

OpenSSL:

sudo apt-get install openssl

Pkg-config:

sudo apt-get install pkg-config

Git:

sudo apt-get install git

Ant:

sudo apt-get install ant-optional

JUnit:

sudo apt-get install junit

Cross-Compiling package – MinGW 64bit:

sudo apt-get install mingw-w64

Get source code into a directory of your choice:
Note: Recently Art added a new branch dedicated to cross-compilation. You might want to test this branch instead.

git clone git://github.com/xuggle/xuggle-xuggler.git

or

git clone -b cross-compile git://github.com/xuggle/xuggle-xuggler.git

I’ve used the cross-compilation branch on my 32 bit compilation and the trunk on my 64 bit compilation.

Set environment variables (add them to ~/.profile if you wish):

export XUGGLE_HOME=/usr/local/xuggler
export PATH=$XUGGLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$XUGGLE_HOME/lib:$LD_LIBRARY_PATH

You need to compile using -fPIC due to the following issue:

1. Edit mk/buildtools/buildhelper.xml and add “–enable-pic” to:

<property name="configure.line"
      value="../../../configure --enable-pic ${build.configure.host.flag} ${build.configure.flag} ${build.configure.maintainer.flag} ${build.configure.debug.flag} --prefix=${xuggle.dir}"/>

2. Edit captive/libvpx/incarcerate.in and add -fPIC to:

CFLAGS="-fPIC @CFLAGS@"

Enable RTMP support (librtmp) – Optional

export XUGGLE_NATIVE_CONFIGURE="--enable-captive-librtmp"

Compile it for Linux:

ant run-tests

Note: If the junit tests fail to compile it might be because the shared libs are not being found (you might have used a different place for XUGGLE_HOME, like I did). To fix this just run “ant install” and re-run the tests “ant run-tests”.

Cross-Compile it for Windows 7 64 bit:

ant -Dbuild.configure.os=x86_64-w64-mingw32 run-tests

Cross-Compile it for Windows 7 32 bit:

ant -Dbuild.configure.os=i686-w64-mingw32 run-tests

Note: Tests will fail for cross compilation since it can not execute the Windows tests on Ubuntu. Before you cross-compile make sure you clean everything from your XUGGLER_HOME directory.

Install packages for Win64:

ant -Dbuild.configure.os=x86_64-w64-mingw32 install

Install packages for Win32:

ant -Dbuild.configure.os=i686-w64-mingw32 install

The install will fail to copy the necessary java jars. Fix it by creating the following directories:

mkdir $XUGGLE_HOME/share/java
mkdir $XUGGLE_HOME/share/java/jars

Copy the jars from your build directory:

cp dist/lib/*.jar $XUGGLE_HOME/share/java/jars

Copy the files from XUGGLE_HOME into Windows 7 64 or 32 bit, install a 64 or 32 bit Java VM respectively in it and you are good to go.

Note: An easy way to copy the files to Windows 7 is to make use of VirtualBox shared folders as shown here.

Enjoy!
