Compiz Introduction and Demo Extra: HOWTO Build the Ubuntu Desktop (the script way)

Step 1: Create the necessary directories and scripts

$ mkdir -p canonical/staging

1	$ mkdir -p canonical/staging

Save the following script as: ~/.unity-bash-functions
(pastebin: http://paste.ubuntu.com/16373441/):

function recreate-build-dir()
{
   rm -r build
   mkdir build
   cd build
}

function remake-autogen-project()
{
    ./autogen.sh --prefix=$HOME/canonical/staging --enable-debug
    make clean && make -j8 install
}

function remake-unity()
{
  recreate-build-dir

}

function recreate-build-dir()

{

rm -r build

mkdir build

cd build

}

function remake-autogen-project()

{

./autogen.sh --prefix=$HOME/canonical/staging --enable-debug

make clean && make -j8 install

}

function remake-unity()

{

cmake .. \

}

function unity-env

{

export PATH=~/canonical/staging/bin:$PATH

export XDG_DATA_DIRS=~/.config/compiz-1/gsettings/schemas:~/canonical/staging/share:/usr/share:/usr/local/share

export LD_LIBRARY_PATH=~/canonical/staging/lib:${LD_LIBRARY_PATH}

export LD_RUN_PATH=~/canonical/staging/lib:${LD_RUN_PATH}

export PKG_CONFIG_PATH=~/canonical/staging/lib/pkgconfig:${PKG_CONFIG_PATH}

export PYTHONPATH=~/canonical/staging/lib/python2.7/site-packages:$PYTHONPATH

export GI_TYPELIB_PATH=~/canonical/staging/lib/girepository-1.0:$GI_TYPELIB_PATH

export XDG_CONFIG_DIRS=~/canonical/staging/etc:$XDG_CONFIG_DIRS

}

Edit the .bashrc to have this line at the end:

. ~/.unity_bash_functions

1	. ~/.unity_bash_functions

Enter the directory staging:

$ cd ~/canonical/staging
$ bzr branch lp:nux
$ bzr branch lp:compiz
$ bzr branch lp:unity

$ cd ~/canonical/staging

$ bzr branch lp:nux

$ bzr branch lp:compiz

$ bzr branch lp:unity

Step 1: Build nux

$ cd ~/canonical/staging
$ export PREFIX=`pwd`
$ cd nux
$ ./autogen.sh --prefix=$PREFIX --enable-debug
$ make && make install

$ cd ~/canonical/staging

$ export PREFIX=`pwd`

$ cd nux

$ ./autogen.sh --prefix=$PREFIX --enable-debug

$ make && make install

Step 2: Build compiz

$ cd ~/canonical/staging/compiz
$ mkdir -p build
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=~/canonical/staging/ -DCMAKE_BUILD_TYPE=Debug
$ make && make install

$ cd ~/canonical/staging/compiz

$ mkdir -p build

$ cd build

$ cmake .. -DCMAKE_INSTALL_PREFIX=~/canonical/staging/ -DCMAKE_BUILD_TYPE=Debug

$ make && make install

Step 3: Build unity

$ export COMPIZ_CONFIG_PROFILE=ubuntu
$ unity-env
$ remake-unity-compiz-path
$ make && make install

$ export COMPIZ_CONFIG_PROFILE=ubuntu

$ unity-env

$ remake-unity-compiz-path

$ make && make install

Run:

Switch to the Unity 7 tty press Ctrl+T to open a terminal and type:

$ export COMPIZ_CONFIG_PROFILE=ubuntu
$ unity-env
$ unity --replace ccp &

$ export COMPIZ_CONFIG_PROFILE=ubuntu

$ unity-env

$ unity --replace ccp &

or just this:

$ unity --compiz-path=~/canonical/staging/bin/compiz --replace ccp &

1	$ unity --compiz-path=~/canonical/staging/bin/compiz --replace ccp &

Note: I use “make -j8” in my script, you might need to change that!
