cross-compiling FFmpeg through Ubuntu Linux



The debian repository at http://apt.arrozcru.org hosts the cross-development toolchain and dependencies used.

1   First add my gpg key to your system

$ gpg --keyserver www.keyserver.net --recv-key 0x25E635F9
$ gpg --export --armor 0x25E635F9 | sudo apt-key add -
[ enter your password ]

2   Now add the repository to your sources.list file

$ echo "deb http://apt.arrozcru.org ./" | sudo tee -a /etc/apt/sources.list
$ echo "deb-src http://apt.arrozcru.org ./" | sudo tee -a /etc/apt/sources.list

3   Now update your package list

$ sudo apt-get update

4   search mingw32 packages

apt-cache search mingw32-

the result is:

mingw32-binutils - Minimalist GNU win32 (cross) binutils
mingw32-runtime - Minimalist GNU win32 (cross) runtime
mingw32-libcloog-ppl - mingw32 libcloog-ppl

mingw32-libmpfr - mingw32 libmpfr
mingw32-libsdl - mingw32 libsdl
mingw32-openssl - mingw32 openssl

6 recompile the cross-toolchain
6.1 create a local directory
$ mkdir cross
$ cd cross

6.2 install necessary compile envionment
$ sudo apt-get install dpkg-dev debhelper autotools-dev libmpfr-dev libgmp3-dev libppl0.10-dev libcloog-ppl-dev libmpc-dev

6.3 recompile and install mingw32-w32api and mingw32-runtime
(should be in the /cross directory)
apt-get source --compile mingw32-w32api
sudo dpkg -i mingw32-w32api*.deb

apt-get source --compile mingw32-runtime
sudo dpkg -i mingw32-runtime*.deb

6.4 recompile and install mingw32-binutils
(should be in the /cross directory)
$ apt-get source --compile mingw32-binutils
$ sudo dpkg -i mingw32-binutils_*.deb

6.5 recompile and install mingw32-gcc-4.4
(should be in the /cross directory)
(it depends on the compilation of mingw32-w32api and mingw32-runtime)
$ apt-get source --compile mingw32-gcc-4.4
$ sudo dpkg -i mingw32-gcc-4.4_*.deb

6.6 test if i686-mingw32-gcc works
i686-mingw32-gcc --version

the result is:
i686-mingw32-gcc (GCC) 4.4.2
Copyright (C) 2009 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

6.7 recompile and install mingw32-pthreads and mingw32-directx

(note: they are need by i686-mingw32-gcc to create a win32 execute file)

apt-get source --compile mingw32-pthreads
sudo dpkg -i mingw32-pthreads*.deb

apt-get source --compile mingw32-directx
sudo dpkg -i mingw32-directx*.deb


7  use apt-get to install the rest of the pre-compiled libraries
note: you can also recompile and install the rest libraries as step 6 has done.

7.1
NULL

7.2
sudo apt-get install mingw32-lib*

(those libs include:  mingw32-libcloog-ppl mingw32-libfaad2 mingw32-libgmp mingw32-libgsm mingw32-libmp3lame mingw32-libmpfr mingw32-libogg mingw32-liboil mingw32-libopencore-amr mingw32-libopenjpeg mingw32-liborc mingw32-libppl mingw32-libschroedinger mingw32-libsdl mingw32-libspeex mingw32-libtheora mingw32-libvorbis mingw32-libvpx mingw32-libx264 mingw32-libxvid
)

7.3
sudo apt-get install mingw32-bzip2 mingw32-zlib mingw32-polarssl mingw32-openssl

7.4
sudo apt-get install liborc-dev


8 install asm compiler
sudo apt-get install yasm



9 configure


(change to ffmpeg source directory and then execute thus command)
./configure --enable-memalign-hack --arch=x86 --target-os=mingw32 --cross-prefix=i686-mingw32- --extra-libs='-lx264 -lpthread'

or

./configure --enable-memalign-hack --arch=x86 --target-os=mingw32 --cross-prefix=i686-mingw32- --extra-libs='-lx264 -lpthread' --prefix=/usr --enable-gpl --enable-pthreads --enable-libgsm --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-pthreads


(configure error can be found in config.err or config.log)
