= Introduction  =
== About ==

MSys is a helper environment for MinGW, the compiler chain for Windows based on GCC. It can build VLC natively on Windows.  Note that you should also [[Win32Compile|cross compile]] VLC from Linux, because it is faster, and feels easier.

VLC is a complex program with many dependencies, so minimal command-line experience is required. Also, don't be in a hurry (4 hours is a minimum for the whole process) and don't despair if it doesn't work first time.

= Windows tools needed  =
== Text editor  ==

To edit unix-style text documents you need a suitable editor. 

You can look at [http://sourceforge.net/projects/notepad2/ notepad2]. You can set File - Line endings - Default to "Unix (LF)", but it always saves opened files in the ending style they have.

Or you can look at [http://notepad-plus-plus.org/ notepad++].

== Unzip Utility (7-zip) ==

Many files to downloaded will have to be uncompressed. As most of them use Linux-originated formats (.tar.gz, .tar.bz2, .tar.lzma), you will need a versatile unzipping utility. A recent version of [http://www.7-zip.org/ 7-zip] is therefore strongly advised. 

Please note that most archives contain directory structures. Unless otherwise stated, you have to merge the contents with the existing dirs

= GNU Windows Environment  =
Before installing, ensure your Windows user name does not contain spaces (VLC will not build in a folder with spaces in it). If it does, please create another user on your system. 

In the following text, we'll refer to this user name as "&lt;username&gt;". Replace it appropriately where needed of course. 

== MinGW  ==
=== TDM/MinGW Setup  ===

Use the installer found at http://sourceforge.net/projects/tdm-gcc/files/TDM-GCC%20Installer/tdm-gcc-4.7.1-2.exe/download

Go through the wizard: 
* Select "Create" 
* Select 32bits
* Install to C:\MinGW 
* Keep default settings

=== MinGW utils  ===

Install mingw-utils, for unix2dos: http://prdownloads.sourceforge.net/mingw/mingw-utils-0.3.tar.gz 

Extract contents to c:\MinGW

== MSys  ==
=== MSys Setup  ===

Use the installer found at http://sourceforge.net/project/downloading.php?group_id=2435&amp;filename=MSYS-1.0.11.exe 

Go through the wizard and install to to default C:\Msys\1.0 

In the command window that opens, answer questions as follows: 

 Accept Post Install: [y]
 MinGW Installed?     [y]
 path to MinGW:       [c:/MinGW]

=== MSys Developer Toolkit  ===

Use the installer found at http://downloads.sourceforge.net/mingw/msysDTK-1.0.1.exe 

Go through the wizard, keeping the default values.

This will install old versions of autotools, perl, ssh, ftp and sftp.

=== Git ===
Install Git from http://code.google.com/p/msysgit/downloads/list?can=3

Go through the wizard, keeping the default value, except the one speaking of line endings.

=== Wget ===
You will need Wget:
http://sourceforge.net/projects/gnuwin32/files/wget/1.11.4-1/wget-1.11.4-1-setup.exe/download

Extract it to c:\MinGW

=== AutoTools and libcrypt  ===

Update autoconf, automake, libtool as well as libcrypt by downloading the following files and extracting them to C:\Msys\1.0: 

*http://sourceforge.net/projects/mingw/files/MSYS/msysdev/autoconf/autoconf-2.68-1/autoconf-2.68-1-msys-1.0.17-bin.tar.lzma/download
*http://sourceforge.net/projects/mingw/files/MSYS/msysdev/automake/automake-1.11.1-1/automake-1.11.1-1-msys-1.0.13-bin.tar.lzma/download
*http://sourceforge.net/projects/mingw/files/MSYS/msysdev/libtool/libtool-2.4-1/libtool-2.4-1-msys-1.0.15-bin.tar.lzma/download
*http://prdownloads.sourceforge.net/mingw/libcrypt-1.1_1-2-msys-1.0.11-dll-0.tar.lzma
*http://sourceforge.net/projects/mingw/files/MSYS/Extension/perl/perl-5.8.8-1/perl-5.8.8-1-msys-1.0.17-bin.tar.lzma/download
*http://sourceforge.net/projects/mingw/files/MSYS/Extension/m4/m4-1.4.14-1/m4-1.4.14-1-msys-1.0.13-bin.tar.lzma/download

=== Glib and PKG-CONFIG  ===

Similarly, download the following files and extract them to C:\MSys\1.0: 

Note* Download the latest version inside this folders (Last tested to be OK is glib 2.28, non-dev version)):

*http://ftp.gnome.org/pub/GNOME/binaries/win32/glib 
*ftp://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/pkg-config_0.23-3_win32.zip 
*ftp://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/pkg-config-dev_0.23-3_win32.zip
*http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/gettext-runtime_0.18.1.1-2_win32.zip

'''Note''': I found that compiling 2.1.0 requires xgettext, msgmerge, msgfmt and so on. These in turn require libiconv. I'm not sure if that suffices as at this point I gave up.

=== Add pkg config path variable  ===

Add the following line to the *top* of C:\MSys\1.0\msys.bat: 

 set PKG_CONFIG_PATH=/win32/lib/pkgconfig

== Compile LUA tools  ==

VLC uses the LUA scripting language (See [http://www.lua.org lua.org]). Unfortunately, no binaries are provided so you need to compile them. 

*Download the lua tools package from http://www.lua.org/ftp/lua-5.1.4.tar.gz 
*Uncompress it in your home folder (C:\MSys\1.0\home\&lt;username&gt;) 
*run MSys
*type the following commands:

 cd /home/<username>/lua-5.1.4 
 make mingw
 make install

= VLC sources  =
== Git ==
Clone the git repo
 git clone git://git.videolan.org/vlc.git

= Get Precompiled contribs  =
 cd vlc/contrib
 mkdir win32 && cd win32
 ../bootstrap --build=i586-mingw32msvc
 make prebuilt

'''Note''': it will say tar complains, just ignore them and watch tar die.
I had to manually execute the rest of the prebuilt target, which consists of

 mv i586-mingw32msvc ..
 cd ../i586-mingw32msvc
 change_prefix.sh

I also found that change_prefix.sh, which rewrites .pc files to deal with their chosen location, used the -i option which is not supported by MSYS-shipped sed. I rewrote the sed script to write changes $file.new then mv $file.new $file.

= Last change&nbsp;: whoami and hostname  =

Whoami is not available on Windows, and hostname doesn't support the -f option used by the build process. These utilities are used to show the name and computer of the person who compiled VLC in the 'About' box. 

:''Note for the brave&nbsp;: the steps below are file changes so that compile works, but an alternative is to download and install GNU whoami and hostname functionality. This can be achieved by doing the following steps:
# ''download coreutils from http://sourceforge.net/projects/mingw/files/MSYS/BaseSystem/coreutils, selecting any version (latter is normally better) then the file named like coreutils-5.97-2-msys-1.0.11-ext.tar.lzma (note '-ext' in file name) and extracting who.exe, whoami.exe, hostname.exe to C:/MSys/1.0/bin''
# ''download libintl dll from http://sourceforge.net/projects/mingw/files/MSYS/BaseSystem/libiconv, selecting any version (latter is normally better) then the file named like libiconv-1.13.1-2-msys-1.0.13-dll-2.tar.lzma (note '-dll' in file name) and extracting dll in C:/MSys/1.0/bin''
# ''download libiconv dll from http://sourceforge.net/projects/mingw/files/MSYS/BaseSystem/gettext, selecting any version (latter is normally better) then the file named like libintl-0.17-2-msys-dll-8.tar.lzma (note '-dll' in file name) and extracting dll in C:/MSys/1.0/bin''

== Whoami  ==

Create a new file containing the single line: 

 echo '&lt;username&gt;'

and save it as C:\MSys\1.0\bin\whoami (without any extension) 

== Hostname  ==

Modify configure.ac so that it doesn't call 'hostname -f' as follows: 

*open C:\MSys\1.0\home\&lt;username&gt;\vlc\configure.ac 
*goto search button:
*change it as follows:

 old: AC_DEFINE_UNQUOTED(VLC_COMPILE_HOST, "`hostname -f 2&gt; /dev/null || hostname`", [host which ran configure])
 new: AC_DEFINE_UNQUOTED(VLC_COMPILE_HOST, "`hostname`", [host which ran configure])

= Build VLC  =

The build is made exclusively from the command line, so if you closed the prompt at the LUA step, re-execute C:\MSys\1.0\msys.bat, then type the commands as mentioned 

== Bootstrap  ==

 cd vlc
 cp -v /usr/share/aclocal/* m4/
 bootstrap 
== Configure  ==

 sh extras/package/win32/configure.sh --host=i586-pc-mingw32msvc --disable-nls

If you want any custom options, like "--disable-lua" or anything of that nature, you can append them.

== Make (compile) ==

Note&nbsp;: If your &lt;username&gt; starts with the "u" or "x" character, change C:\MSys\1.0\home\&lt;username&gt;\config.h and double all backslashes in VLC_COMPILED_BY constant. 

Type the following command&nbsp;: 

 PATH=/usr/win32/bin:$PATH make

If this step fails, try the following
* Go back to "Precompiled contribs" section, and obtain the latest compiled contrib (under "Note for the brave")
* In the configure script section (configure-msys.sh), open that file and add --disable-upnp

== Create self-contained packages  ==

Once the compilation is done, build self-contained VLC packages with one of the following "make" commands: 

 make package-win32-base

(This will create a subdirectory named vlc-x.x.x with all the binaries "stripped" without any debugging symbols). 

 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 will need to have NSIS installed in its default location for this to work).

 make package-win32-base-debug

(This will create a subdirectory named vlc-x.x.x with all the binaries containing debug info usable by gdb).

Note that with the 1.2 branch these names have changed slightly.  Run '
 grep ':' Makefile | grep package-win32
to see what they are now.
