Building Clutter with mingw
===========================

The mingw-cross-compile.sh script in this directory automates
compilation of Clutter using the MinGW compiler. You can run it from
Linux to cross compile or you can use MSYS and MinGW to compile it
directly on Windows.

If you were looking to build Clutter with Visual Studio instead there
is an external project which is maintaining build files for Clutter
(and other glib-based projects) here:

  https://launchpad.net/oah

For cross compiling you need to have the compiler installed. The
script should automatically download all other dependencies. Under
Ubuntu (and probably other Debian-based distros) you can install the
compiler with this command:

  sudo apt-get install mingw32{,-binutils,-runtime}

To compile clutter,

  mkdir build_dir
  cd build_dir
  ./mingw-cross-compile.sh

and follow the prompts.

Building under MSYS
===================

Building directly under Windows requires some extra work to get some
basic utilities installed. Here are step-by-step instructions to build
from a clean installation of Windows:

First you need to install the MinGW and MSYS packages from [1].

Select the top package called 'Automated MinGW Intaller' and download
the exe of the latest version. Run the executable and install to the
default location. Make sure you DON'T install 'MinGW make' to make
life easier.

Next download the 'MSYS Base System'. Use the .exe installer from
'Current release' (not the technology preview). Run the executable and
install to the default location. Answer yes to whether you want to
continue with the post install and tell it the location where you
installed MinGW (which should be c:/MinGW).

Next install the 'MSYS supplementary tools'. Again select .exe from
the current release and install it to the default location.

To get the dependencies we want to run the mingw-cross-compile.sh
script. However to do this we first need some extra utilities.

Make a directory called c:/msys/1.0/clutter-work and another directory
called downloads under that. Go back to the SourceForge page for MinGW
and select the 'User Contributed: mingwPORT' section. Download the
wget tarball to the newly created downloads folder.

Start MSYS and type the following to install wget.

cd /clutter-work/downloads
tar -jvxf wget-1.9.1-mingwPORT.tar.bz2
cd wget-1.9.1/mingwPORT
mkdir /usr/src
PATH="$PATH":"$PWD" ./mingwPORT.sh 

Press enter at each question to just use the default

Next we need to install unzip.exe which we can get from the GNUWin32
ports. Visit here [2] and download the 'complete package, except
sources'. Install it to the default location.

Now we can type the following to download and install the clutter
dependencies using the helper script:

cd /clutter-work
wget -O downloads/mingw-cross-compile.sh \
http://folks.o-hand.com/neil/mingw-cross-compile.sh
PATH="$PATH:/c/Program Files/GnuWin32/bin" \
sh ./downloads/mingw-cross-compile.sh

Press enter to all of the questions to get the default except the 'Do
you want to download and install Clutter' question because that will
try to use Git which we don't have installed.

Next we need to install pkg-config to get Clutter's configure script
to work. Type the following:

cd /clutter-work/downloads
wget 'http://pkgconfig.freedesktop.org/releases/pkg-config-0.23.tar.gz'
tar -zvxf pkg-config-0.23.tar.gz
cd pkg-config-0.23
prefix=/clutter-work/clutter-cross
libdir="${prefix}/lib"
includedir="${prefix}/include"
CFLAGS="-g -O2 -Wall -I${includedir}/glib-2.0 -I${libdir}/glib-2.0/include" \
LDFLAGS="-L${libdir} -lglib-2.0 -lintl -liconv" \
./configure
make all install

Now we should finally be ready to compile Clutter:

cd /clutter-work/downloads
wget http://www.clutter-project.org/sources/clutter/1.0/clutter-1.0.0.tar.bz2
cd ..
tar -jvxf downloads/clutter-1.0.0.tar.bz2
cd clutter-1.0.0
PKG_CONFIG_PATH=/clutter-work/clutter-cross/lib/pkgconfig \
 PATH="$PATH:/clutter-work/clutter-cross/bin" \
 CFLAGS="-mms-bitfields -I/clutter-work/clutter-cross/include -g -O2 -Wall" \
 ./configure --prefix=/clutter-work/clutter-cross --with-flavour=win32
make all install

Now to prove that it worked we can run test-actors. Windows needs the
Clutter DLL to be in the system path for this to work so type the
following:

export PATH="$PATH:/clutter-work/clutter-cross/bin"
cd /clutter-work/clutter-1.0.0/tests
.libs/test-actors

If you want to compile a simple app without using autotools, it's
easiest to use the libtool generated in the Clutter source so that it
can work some voodoo with the included libraries. This assumes you've
still got your path set up from the previous test:

libtool --mode=link gcc -Wall -g -o simple-app simple-app.c \
-I/clutter-work/clutter-cross/include \
`PKG_CONFIG_PATH=/clutter-work/clutter-cross/lib/pkgconfig
    pkg-config clutter-0.8 --cflags --libs`

Enjoy!
