Introduction

This is a guide for cross-compiling VLC for Windows CE on Linux with a step-by-step instruction to download, install, configure and build your VLC.

First, you might want to take a look at compiling instructions for Win32, as the process is roughly the same, and it includes useful discussion and explanations.

Building VLC

Prepare your environment

VLC uses automake, autoconf and friends for compilation. Make sure they are up to date and usable for your system.

Get mingw32ce

To compile VLC, we use Mingw32CE, a cross-development environment for Windows CE. Download the latest version on Sourceforge.

Go the the directory where you dowloaded CeGCC, and untar it, for example:

% tar xjf arm-mingw32ce-0.59.1.tar.bz2 -C /

You should now see the folder /opt/mingw32ce.

Get the source

Start by getting the source, using FTP for releases, or using Git for development. If your are using the release, download source code and extract the archive and go into your VLC directory.

% cd /path/to/your/vlc/folder/

If you are using the Git version, start by bootstrapping your VLC.

% cd /path/to/your/vlc/folder/
% ./bootstrap

Get the contribs

You can get official WinCE contribs on http://download.videolan.org/pub/testing/contrib/, for example contrib-20091114-wince-bin-gcc-4.1.0-runtime-3.15.2-only.tar.bz2. Uncompress them in /usr/wince

Configuration

You need to tweak your configure line.

./configure is used to check whether your system is able to compile VLC. Also you choose the functionalities of your build.

% ./configure --help

will show you the various options

Create a new file named conf-vlc.sh and add in it:

PATH=/opt/mingw32ce/bin:$PATH \
CPPFLAGS="-I/usr/wince/include -D_WIN32_WCE=0x0500" \
LDFLAGS="-L/usr/wince/lib" \
PKG_CONFIG_LIBDIR=/usr/wince/lib/pkgconfig \
./configure --host=arm-mingw32ce --enable-optimize-memory \
            --disable-directx --disable-dvdnav --disable-libgcrypt \
            --disable-mad --disable-remoteosd --disable-sdl --disable-skins2

You will probably want to add more options like --disable-sout --disable-httpd --disable-vlm to remove stuff that you won't need if your device is limited in storage space and memory.

Save the file and make it executable:

% chmod u+x conf-vlc.sh

Compiling source code

Now run your configuration script and build VLC:

% ./conf-vlc.sh
% make

Creating self contained packages

Once the compilation is done, you can build self-contained VLC packages with the following command:

make package-wince

This will create a vlc-x.x.x.zip archive. Transfer it on your device, uncompress it and enjoy!

There is not (yet) an option to build a .cab file.

Using and Debugging VLC

Interacting with your device

Use SynCE to synchronize your device with Linux. Or find an Windows machine with ActiveSync installed and download your fresh new VLC build.

Debugging VLC

CeGCC provides a stub for GDB to permit remote debugging on Windows CE. To use it, go in the vlc folder:

% cd vlc-1.0.0
% arm-mingw32ce-gdb vlc.exe

This GDB will upload vlc.exe to /gdb/ on the device. Make sure you uploaded all the VLC directory on your device.

Then, follow the demo of a debugging session for Windows CE.

Common errors

Well... I don't remember right now all the weird errors I encountered, but if you find one, I may have seen it before, so contact me, I'll help you and add it here. --Geal 10:37, 2 September 2008 (CEST)
