Win32Compile Under Fedora

How to compile VLC media player for Windows under Fedora.

Building Methods

From a Fedora 64-bit install, you have two basic approaches if you want to build VLC from source.

Method	Documentation	Notes
Cross-compile with Mingw in a virtual machine.	Preferred method that works "out of the box".
Cross-compile with Mingw under Fedora.	Produces some anomalies and requires some workarounds.

Yum is the basic installation tool for Fedora. Install packages (as root):

$ sudo yum install ''package-name1 package-name2 ...''

Using a virtual machine

Virtual Box is known to work for this approach.

$ sudo yum install VirtualBox-OSE

The basic Win32Compile is optimized for Ubuntu. It is simpler if you install the 32-bit version:

$ wget http://www.ubuntu.com/start-download?distro=desktop&bits=32&release=latest

Create and attach the disk drives

Start the VirtualBox Manager GUI.

• Click on Machine / New... The "New Virtual Machine Wizard" will open.
• Click Next. Enter Ubuntu32 in the Name box.
• Set Base Memory Size to 1024MB. (Recommended.)
• Leave Start-up Disk box checked. Leave Create new hard disk radio button active.
• Choose VDI file type.
• Choose Dynamically allocated
• Choose Location Ubuntu32 and Size 8.00 GB
• Click "Create". This will exit the Wizard.
• Click "Create" again. This will create the virtual machine.
• Click Settings / Storage. The SATA Controller should show that Ubuntu32.vdi (your 8GB disk) is attached. The IDE Controller should show an empty attachment. Click on the Empty line. The Attributes label in the last column should read "CD/DVD Drive:" with a dropdown reading "IDE Secondary". To the right of that is a CD symbol. Click on that.
• Click on "Choose a virtual CD/DVD disk file..."
• Navigate to the Ubuntu server you just downloaded. Click Open. Your CD should now be attached to the IDE Controller. Click OK.
• Click on Start.

At this point, the virtual machine should boot and take you through the Ubuntu installation process. When it is complete, it will ask you to remove the CD and reboot.

Removing the CD and rebooting

• Click on Machine / Close ...
• Choose Power off the machine and click OK.
• Click on Settings / Storage
• Click on the Ubuntu CD attached to the IDE Controller
• Click on the CD symbol at the extreme right of the Attributes section.
• Choose Remove disk from virtual drive. Click OK
• Click on Start.

Now Ubuntu should start. From here you can follow the instructions on the main Win32Compile page.

Using Fedora

It is possible to compile the Windows 32-bit version under 64-bit Fedora. There are a few complications, as noted below.

Get the source code

First, change to a directory you will use for building. You must have write access to this directory. Then use git to get the source:

$ git clone git://git.videolan.org/vlc.git

This will give you the VLC trunk. Alternative branches (technically forks) are listed at http://git.videolan.org. Scroll down to the vlc.git line and click on the "forks" link at the extreme right. This will give you a list of alternatives, which are in the vlc directory. So, for example, to choose the 2.0 fork, the command is:

$ git clone git://git.videolan.org/vlc/vlc-2.0.git

Next, change into the newly installed vlc-x.x directory. We will refer to this as the $VLCROOT directory:

$ cd vlc-*
$ export VLCROOT=`pwd`

Obtaining the toolchain

The mingw32 cross-compile tools are available in the default repository.

$ sudo yum install \
mingw32-gcc-c++ \
mingw32-gcc \
mingw32-pthreads \
mingw32-w32api \
mingw32-binutils \
mingw32-runtime \
mingw32-filesystem \
mingw32-cpp \
mingw32-dlfcn-static

Prepare 3rd party libraries

Before compiling VLC, you need lots of other libraries. Here is how to get them:

$ mkdir -p contrib/win32
$ cd contrib/win32
$ ../bootstrap --host=i586-mingw32msvc
$ make prebuilt
$ cd ..  
$ ln -s i586-mingw32msvc i686-pc-mingw32

Note that i686-pc-mingw32 is the current name of the "host" system for cross-compiling. You can verify that by:

$ rpm -ql mingw32-filesystem|grep -m1 lib|cut -d/ -f3

Installing 32-bit Lua

By default, you will already have 64-bit Lua installed, because the Yum/RPM packaging system depends on it. As a result, you will not be able to remove the 64-bit version. Furthermore, you may install the 32-bit binary libraries, but the 32-bit binary executables (lua and luac) will NOT install over the 64-bit ones. Here is how to work around that.

$ sudo yum install compat-readline5.i686 
$ yumdownloader lua.i686
$ sudo yum localinstall ./lua*.rpm

This installs the 32-bit libraries but not the executables. You have to manually extract and install the 32-bit versions.

$ sudo yum install cpio
$ rpm2cpio lua*.rpm | cpio -idmv

Now you will have the files from the RPM package as a tree in your local directory. They have the same names and (relative) locations as the 64-bit versions, which is why Yum refused to install them in the first place. So manually install them with the names lua32 and luac32 and get rid of your detritus.

$ sudo mv usr/bin/lua /usr/bin/lua32
$ sudo mv usr/bin/luac /usr/bin/luac32
$ rm -rf usr
$ rm -f lua*.rpm

Tell the build system where to find the 32-bit versions.

$ export LUA=/usr/bin/lua32
$ export LUAC=/usr/bin/luac32

Installing Qt and Correcting Version Mismatch

Install the qt-devel package, which gives you moc, uic and rcc for both Qt3 and Qt4. The executables for Qt4 are named moc-qt4, uic-qt4 and rcc, so these need fixing as well.

$ sudo yum install qt-devel
$ sudo ln -s /usr/bin/moc-qt4 /usr/local/bin/moc
$ sudo ln -s /usr/bin/uic-qt4 /usr/local/bin/uic

Your version of moc needs to match the version used in the contribs.

$ moc -v
Qt Meta Object Compiler version 63 (Qt 4.8.0)
$ grep "define Q_MOC" contrib/win32/i586-mingw32msvc/include/qt4/src/corelib/kernel/qobjectdefs.h
#define Q_MOC_OUTPUT_REVISION 62

In this case, the installed moc has a version of 63 (from Qt 4.8), but the contribs were built with version 62 (from Qt 4.7). To fix this:

$ cd contrib/win32
$ wget http://johnfreed.com/vlc/contrib/moc-`moc -v 2>&1|cut -d' ' -f6`.tar.bz2



=== tools ===
You will also need:
* lua5.1
* all autotools: libtool, automake, autoconf, autopoint, make, gettext
* pkg-config
* git
* subversion
* cmake, cvs if you want to rebuild contribs
* zip [for creating .zip package], p7zip [for .7z package], nsis [for .exe auto-installer].



=== Linux 64-bit ===

If you are on Linux '''64-bit''', you '''MUST''' remove some files:

  $ rm -f ../i586-mingw32msvc/bin/moc ../i586-mingw32msvc/bin/uic ../i586-mingw32msvc/bin/rcc

In addition, install the ''qt4-tools'' package.

=== Fix your contrib path ===

If your Mingw prefix is not ''i586-mingw32msvc'' (you are NOT on Debian or Ubuntu), create a symlink to contribs:

=== Go Back  ===

Go back to the VLC source directory: 

  $ cd -

== Configuring the build  ==

=== Bootstrap ===
First, prepare the tree:
  $ ./bootstrap

=== Configure ===
Then you can to configure the build with the <code>./configure</code> script. 

Create a subfolder:
  $ mkdir win32 && cd win32

Use the standard configuration: 
 $ ../extras/package/win32/configure.sh --host=i586-mingw32msvc
'''NB''': use '''YOUR''' Xcompiling prefix here, like ''i486-mingw32''


Alternatively, you can run configure manually:
 $ ../configure --host=i586-mingw32msvc
See <code>'../configure --help'</code> for more information.

== Building VLC  ==

Once configured, to build VLC, just run:
  $ make

== Packaging VLC ==
Once the compilation is done, you can build self-contained VLC packages.

You may also add the ndis tools and everything needed by the <code>make package-win32*</code> targets:
<pre>
sudo yum --verbose --noplugins install \
mingw32-nsiswrapper \
mingw32-nsis \
zip \
p7zip \ 
lua

Use the following make rules:

Command	Description
make package-win-common	Creates a subdirectory named vlc-x.x.x with all the binaries. You can run VLC directly from this directory.
make package-win-strip (might be package-win32-strip)	Same as above but will create 'stripped' binaries (that is, smallest size, unusable with a debugger).
make package-win32-7zip	Same as above but will package the directory in a 7z file.
make package-win32-zip	Same as above but will package the directory in a zip file.
make package-win32	Same as above but will also create an auto-installer package. You must have NSIS installed in its default location for this to work.

Well done—you're ready to use VLC!
