Win32CompileCygwinNew

This is a new version of the Win32CompileCygwin written by Jean-Baptiste Kempf

This version ONLY works for 0.9.x, for 1.0.x and for 1.1.x.

WARNING: building VLC on Cygwin has ever been a failure-prone task. It is also very slow (specially if you enable debug and optimizations). If you want to build on windows, Win32CompileMSYSNew is a much better option. Otherwise, you should strongly consider cross-compiling from Linux (on a virtual machine, via dual-boot or from another computer). You were warned.

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 (optional: for building extras/contrib)
  gcc
  gcc-core
  gcc-g++
  gcc-mingw
  gcc-mingw-core
  gcc-mingw-g++
  gdb
  gettext
  gettext-devel
  git
  libgcrypt-devel
  libiconv
  libtool
  make
  mingw-runtime
  nasm
  patchutils
  pkg-config
  subversion (optional: for building extras/contrib)

Editor
  vim

Libs
  expat
  libgcrypt

Utils
  ncurses

Web
  curl (optional: for building extras/contrib)
  wget (optional: for building extras/contrib)

Cygwin environment

Start Cygwin from the icon on your desktop (With Windows Vista run it with admin rights, so right click and select "Run as administrator"). 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

or if you just want to download latest VLC revision (saves bandwidth)

git clone git://git.videolan.org/vlc.git --depth 1

or if your proxy denies git protocol connections use:

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

In this case you need to set the proxy address first:

export http_proxy = <proxy>:<port>

If git fails for some reason, then please try to use git from basic Windows command prompt (Start -> Run -> cmd), not from Cygwin shell.

Please note that the very latest VLC sources ("master" branch) does not necessary build fine all the time. So if you need something stable, better is to use a git tag or a version snapshot archive.

Snapshots

You can do the same by using the snapshots in the nightly builds site.

Specific Version

You can get a specific version of VLC source code from the source ftp directory.

Another option is to sync specific version represented by a tag in git:

git checkout <version>

where <version> is one like: 1.0.1, 1.0.2, ..

Bootstrap

First move to vlc folder, if you aren't already there

cd vlc

and then run bootstrap.

dos2unix botstrap

./bootstrap

You should go through dos2unix for every script which produces errors related to '\r'

It might fail with some unable to remap error <some_dll_file_name>. It seems you need to rebase all Cygwin DLLs: close all your cygwin applications and launch 'ash' from basic windows command prompt (Start -> Run -> cmd), from there run rebaseall (so start e.g. C:\cygwin\bin\ash.exe and type there text below).

/bin/rebaseall -v

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/ or http://people.videolan.org/~jb/Contribs/ or take

ftp://ftp.videolan.org/pub/vlc/1.0.0/win32/contrib-1.0.0.tar.bz2

Download the latest version of a "contrib" package for win32:

contrib-20080702-win32-bin-gcc-4.2.1-sjlj-runtime-3.13-only.tar.bz2 (this is an example so DON'T download packages this old, unless you really have to!)

It's a good idea to check the INSTALL.Win32 file in the VLC source directory for the appropriate contrib download file if you build older VLC versions.

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:

rm -rf /usr/win32
cd /cygdrive/c/VLC/Downloads
tar xf contrib-20080702-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 (/usr/win32 folder) instead of extracting a new version on top of it.

Version 1.0.2 of VLC source code has been tested and found working with contrib-20091020-win32-bin-gcc-4.2.1-sjlj-runtime-3.15.2-only.tar.bz2

Keeping the Win32 "contrib" package up-to-date

For maintenance purposes periodically check:

http://download.videolan.org/pub/testing/win32/

QT4 issues

There are some QT4 and winapi issues (like InterlockedCompareExchange error) which you can work out with information you get from http://forum.videolan.org/viewtopic.php?f=14&t=50360&p=164758&hilit=win32api#p164219 and http://forum.videolan.org/viewtopic.php?f=14&p=175301#p175301 threads. If you don't plan to compile QT4 or skins2 interface, you can skip this.

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_LIBDIR=/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 \
     --enable-nls \
     --enable-sdl --with-sdl-config-path=/usr/win32/bin \
     --enable-faad --enable-flac --enable-theora \
     --enable-live555 --with-live555-tree=/usr/win32/live.com \
     --enable-caca --with-caca-config-path=/usr/win32/bin \
     --with-dvdnav-config-path=/usr/win32/bin \
     --enable-goom \
     --enable-dvdread \
     --enable-debug --disable-optimizations \
     --disable-mkv --disable-taglib --disable-zvbi --disable-dirac --disable-x264 --disable-fluidsynth

This command is tested and configures VLC 1.0.2 properly so that it builds fine.

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 linuxs 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

After your configure-vlc.sh is completed, copy it to your vlc directory and run it:

./configure-vlc.sh

If it complains about permissions, use chmod and try again:

chmod 777 configure-vlc.sh

NOTE. (If you plan to use JVLC) To make vlc-control.dll accessible by Java on Windows configure-vlc.sh should be modified to include "-Wl,--add-stdcal-alias". Example:

...
CC="gcc -mno-cygwin -Wl,--add-stdcall-alias" CXX="g++ -mno-cygwin -Wl,--add-stdcall-alias" \
./configure \
...

Mozilla plugin

If you want to build Mozilla plugin, add this to your configure-vlc.sh

--enable-mozilla --with-mozilla-sdk-path=/usr/win32/gecko-sdk

If configure-vlc.sh goes correctly, you should see plugins/bindings : activex mozilla

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

NOTE: Open /cygdrive/c/VLC/libtool in text editor and if "global_symbol_pipe =" line is blank, replace it with :

global_symbol_pipe="sed -n -e 's/^.*[   ]\\([ABCDGIRSTW][ABCDGIRSTW]*\\)[       ][      ]*\\(\\)\\([_A-Za-z][_A-Za-z0-9]*\\)\$/\\1\\2\\3 \\3/p'"

Build it! (remember to run configure-vlc.sh before first build)

make

Cross your fingers and wait... because it might take few hours before compilation is done. If you have multicore CPU or multi CPU box, you can use -j2 switch (or maybe -j3 or -j4 etc.) to speed up make process

make -j2

Creating self contained packages

Once the compilation is done, 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).

• If you have permissions problems running make package-*, chmod 777 -R the vlc folder.
• If you have permissions problems running vlc.exe after packaging, rename or delete vlc.exe.manifest

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:

#0  0x0041394c in playlist_ItemGetById (p_playlist=0x19ec4f8, i_id=29)

(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

+ 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. You can use export TMPDIR="/cygdrive/c/temp" or any directory for it (/cygdrive/c/temp is same as C:\temp). If this doesn't help, make sure you run cygwin with admin rights (With Windows Vista, right click cygwin shortcut and select "Run as administrator"). Avira AntiVir might also cause issues to m4, so disabling it while ./bootstrap might help.

Compiling faster

Building VLC on Cygwin is really slow, but you can spend less time recompiling by using ccache. This software saves the files compiled with their compilation command, and output them if they were not changed and if the compilation command is the same as last build. It is really useful for frequent make clean && make. To use it, change the CC line in your configure script to:

 CC="ccache gcc -mno-cygwin" CXX="ccache g++ -mno-cygwin" \

The first build after reconfiguring will be as slow as ever, but the following builds will be faster.
