Introduction
This is a guide for Windows users with a step-by-step instruction to download, install, configure and build your VLC.
This guide uses Cygwin a Linux-like environment for Windows used for compilation of the VLC source code.
Start off by creating a VLC and a download folder on your hard drive where you can put all the installation files:
C:\VLC\ C:\VLC\Downloads
For further reference, the assumption is made that the local user will be 'Administrator'.
Cygwin
Download the latest Cygwin setup and save it in your download location:
C:\VLC\Downloads\
More info about Cygwin can be found at http://www.cygwin.com or http://sourceware.org/cygwin
Selecting Cygwin packages to install
Run the setup program with the following options:
Installation type : Install from Internet (default)
Root directory : C:\cygwin (default)
Local Package directory : C:\VLC\Downloads\cygwin (your download location)
Internet Connection : Direct Connection (preferred, if it fails try another)
Download Site : Choose a download site closest to you (FTP preferred)
At the "Select Packages" section of the installation process you can select packages by clicking the button with the rotating 2 arrows. (This is under the "New" section). It shows "Skip" next to the button if the package isn't selected yet.
Clicking the button a few times will rotate through the possible package versions including "Skip" (meaning do not install or remove if installed) and "Keep" (meaning keep using the current installed version). If a package was already installed it will also show the "Current" version just to the left of it.
Select the following packages (some others will automatically be selected as well):
Archive unzip zip
Devel autoconf automake binutils cvs expat gcc gcc-core gcc-g++ gcc-mingw gcc-mingw-core gcc-mingw-g++ gdb gettext gettext-devel git libtool1.5 make mingw-runtime nasm patchutils pkg-config subversion Editor vim
Lib libgcrypt
Web curl (optional: for building extras/contrib) wget (optional: for building extras/contrib)
Cygwin environment
Start Cygwin from the icon on your desktop. If it runs for the first time it will automatically create a home\"username" folder in the Cygwin environment; user being the currently logged on Windows user. Assuming this is the 'Administrator' user it will create the following folder:
C:\cygwin\home\Administrator (example)
NOTE: On your desktop, you can rightclick the Cygwin icon and (in the Options field of the Cygwin Properties) set the Command history Buffer size to as large as possible: 999. This setting will make it possible to scroll back further in the Cygwin environment.
VLC source code
Git
The very latest VLC source code can be obtained through a tool called Git. The Cygwin package we're about to install comes with an internal git component.
cd /cygdrive/c/VLC/
git clone git://git.videolan.org/vlc.git
Snapshots
You can do the same by using the snapshots in the nightly builds site.
Bootstrap
Open the configure.ac file, and modify the requirement for gettext 0.16.1 to 0.15.
cd vlc-trunk ./bootstrap
External libraries to the source code
VLC depends on other libraries (code) to provide some features like AC3 audio or MPEG-4 video encoding/decoding etc.
Depending on your needs you will have to install and compile some or all of these external libraries.
Get the Win32 "contrib" package
A package with most of these libraries already compiled so it's actually really easy to compile a full-featured version of vlc can be found here:
http://download.videolan.org/pub/testing/win32/
Download the latest version of a "contrib" package for win32:
contrib-20060730-win32-bin-gcc-3.4.5-only.tar.bz2 (example)
Those days, you should use
http://people.videolan.org/~jb/Contribs/contrib-20080215-win32-bin-gcc-4.2.1-sjlj-runtime-3.13-only.tar.bz2
It's a good idea to check the INSTALL.Win32 file in the VLC source directory for the appropriate contrib download file.
Save it into your download location:
C:\VLC\Downloads\
Installing the Win32 "contrib" package in Cygwin
Start Cygwin and enter the following command in your shell:
cd /cygdrive/c/VLC/Downloads tar xf contrib-20080215-win32-bin-gcc-4.2.1-sjlj-runtime-3.13-only.tar.bz2 -C /
Replace with your version of the "contrib" file and DON'T FORGET THE / (slash) at the end.
This will extract the contents of the file into usr/win32 folder within your Cygwin environment.
NOTE: Make sure to DELETE your old version instead of extracting a new version on top of it.
Keeping the Win32 "contrib" package up-to-date
For maintenance purposes periodically check:
http://download.videolan.org/pub/testing/win32/
Configure
In order to make our lives just a bit easier the following section describes what commandline options should be used for compiling and those commands will then be put into a "script" that can be executed (rather than having to copy and paste all the time).
Configure script for compiling VLC
Create a new text document with the following lines:
PATH=/usr/win32/bin:$PATH \
PKG_CONFIG_PATH=/usr/win32/lib/pkgconfig \
CPPFLAGS="-I/usr/win32/include -I/usr/win32/include/ebml" \
LDFLAGS=-L/usr/win32/lib \
CC="gcc -mno-cygwin" CXX="g++ -mno-cygwin" \
./configure \
--host=i686-pc-mingw32 \
--disable-gtk \
--enable-nls --enable-sdl --with-sdl-config-path=/usr/win32/bin \
--enable-ffmpeg --with-ffmpeg-mp3lame --with-ffmpeg-faac \
--with-ffmpeg-zlib --enable-faad --enable-flac --enable-theora \
--with-wx-config-path=/usr/win32/bin \
--with-freetype-config-path=/usr/win32/bin \
--with-fribidi-config-path=/usr/win32/bin \
--enable-live555 --with-live555-tree=/usr/win32/live.com \
--enable-caca --with-caca-config-path=/usr/win32/bin \
--with-xml2-config-path=/usr/win32/bin \
--with-dvdnav-config-path=/usr/win32/bin \
--disable-cddax --disable-vcdx --enable-goom \
--enable-twolame --enable-dvdread \
--enable-debug --enable-dca \
--disable-mkv --disable-taglib
NOTE: The following options are added for debug purposes and makes the final package a bit larger but the advantage is it's easier to debug in case of crash reports:
--disable-optimizations --enable-debug
If you want to report a crash bug to the VLC team, it is necessary that you provide a stack backtrace. Unfortunately, Windows automatic crash reporter cannot generate such a backtrace as debug symbols used by GCC compiler aren't understood by Windows, therefore we suggest that you install Dr. MinGW (http://jrfonseca.dyndns.org/projects/gnu-win32/software/drmingw/) which will extend Windows Just-In-Time Debugger and provide the necessary debug information.
NOTE: The following options is needed for Qt4 support:
--enable-qt4
As of version 0.9.0 VLC will include the Qt interface. More information can be found about QT here: http://www.trolltech.com
The "Win32 contrib package" at present includes the linux and Windows equivalents of uic, moc and roc executables which are required for building this interface.
The linues executables have to be deleted from the contrib folder:
C:\cygwin\usr\win32\bin\moc (example) C:\cygwin\usr\win32\bin\rcc (example) C:\cygwin\usr\win32\bin\uic (example)
Save as filename in your "scripts" folder at your download/install location:
configure-vlc.sh
NOTE: Save using "All files" and not "Text files" otherwise Windows might append the extension .txt
Copy the file into your home directory:
C:\cygwin\home\Administrator
Start Cygwin and enter the following command in your shell:
dos2unix configure-vlc.sh
POSIX emulation layer
VLC can be built with or without the so called POSIX emulation layer. Without is the default and is usually better (and with hasn't been tested for quite some time). If you do want to use the emulation layer, then just leave out the line with the following options:
CC="gcc -mno-cygwin" CXX="g++ -mno-cygwin"
Compiling source code
It's time to start Cygwin again...
Compiling VLC
Enter the following commands in your Cygwin shell:
cd vlc-trunk
Build it!
make
Cross your fingers...
Creating self contained packages
Once the compilation is done, you can either run VLC directly from the source tree or you can build self-contained VLC packages with 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).
Advanced usage
Updating Cygwin package versions
If you need to update or install additional packages you can just run the Cygwin setup.exe from your download location:
C:\Downloads\cygwin\setup.exe (example)
GDB (Gnu Debugger)
This section requires that you installed the gdb (Gnu Debugger) in Cygwin.
This is a typical example of creating a crashlog:
cd vlc-trunk
gdb --args vlc.exe --fast-mutex --reset-config --reset-plugins-cache
NOTE: vlc-0.9.0 uses libtool for building sources, if you want to debug from the source tree, you should type the following command instead:
libtool -mode=execute gdb --args vlc --reset-config --reset-plugins-cache
In the debugger mode run the program and make sure you reset the preferences!
(gdb) run
NOTE: the (gdb) is just a prompt which means you are in the debugger mode, please note that --fast-mutex option is no longer supported in vlc-0.9.0
It will now take a lot longer than usual for VLC to start :)
Now operate VLC as you would normally do. As soon as a crash issue occurs you'll notice a line like this:
Program received signal SIGSEGV, Segmentation fault.
0x0041394c in playlist_ItemGetById (p_playlist=0x19ec4f8, i_id=29)
at src/playlist/item-ext.c:459
---Type <return> to continue, or q <return> to quit---
459 i = i_bottom + ( i_top - i_bottom ) / 2;
Now you can do a "backtrace" by using the bt command:
(gdb) bt
And output similar to this will be created:

(gdb)
To backtrace all the running threads use:
(gdb) thread apply all bt
These are the log outputs that are more usefull to developers than just mentioning "it crashes"!
NOTE: In GDB mode there are sometimes situations where GDB initially "crashes" on certain network activity (opening network shares, network traffic) which in normal operation does not occur. Just select c for continue until "normal" operation continues.
Common errors
vlc.exe: Permission denied
A make finished successfully and produced vlc.exe, but running the executable returns the following:
bash: ./vlc.exe: Permission denied
The permissions on both vlc.exe & vlc.exe.manifest must be set to executable.
FIX: Type the following:
chmod 755 vlc.exe vlc.exe.manifest
error: parse error before '(' token
A make (compile) of FFmpeg results in the following error:
/usr/include/sys/unistd.h:203: error: parse error before '(' token
make[1]: *** [ffm.o] Error 1
It's very likely you are usix the POSIX emulater which you shouldn't...
FIX: compile with the option
-mno-cygwin

Basically in case of conflict svn adds "<<< mine" and "=======" and ">>>> r1242" which makes gcc complain.
FIX: revert the offending file
Objective C source seen but `OBJC' is undefined
The configure process stops halfway.

Stop.
This problem is related to a warning earlier on and only occured in a few revisions where a built-in workaround wasn't working properly:
+ echo 'Enabling provisional autoconf 2.59 work-around. Update autoconf ASAP.' Enabling provisional autoconf 2.59 work-around. Update autoconf ASAP.
FIX: update autoconf to 2.60 or newer. If Cygwin doesn't provide this version yet then build it yourself from extras/contrib.
Enter the following commands in your Cygwin shell:
cd vlc-trunk/extras/contrib
./bootstrap
cd src
make .autoconf
There should now be compiled autoconf version (probably 2.60 or newer) in extras/contrib that the bootstrap process will use.
Now start the whole "Compile VLC" process from the start again.
Error: cannot create temporary file for diversion: Permission denied
If the above error appears, it might mean you don't have the TMPDIR defined in cygwin. You will need to define it and have its value point to your temporary directory.
