Building Unity from Source
In this guide you will build a separated version of Unity trunk (locally installed to your home directory), so you don't need to worry about corrupting the version from the Ubuntu repositories and you also won't need to get root permissions throughout the whole process (except for installing the build dependencies).
0. Installing build dependencies
You'll need to run this once to install all necessary build dependencies:
sudo apt-get install bzr cmake compiz-dev gnome-common libbamf3-dev libboost-dev \
libboost-serialization-dev libgconf2-dev libgdu-dev libglewmx1.6-dev \
libgnome-desktop-3-dev libibus-1.0-dev libindicator3-dev libjson-glib-dev \
libnotify-dev libnux-2.0-dev libpci-dev libsigc++-2.0-dev libunity-dev \
libunity-misc-dev libutouch-geis-dev libxxf86vm-dev libzeitgeist-dev xsltproc
If you have source code repositories (aka
deb-src) enabled, you can instead use:
sudo apt-get build-dep unity
1. Preparing the environment
PREFIX with the directories you'd like the source and build files to go. In this example I put both in my home directory:
mkdir -p "$PREFIX"
mkdir -p "$SOURCE"
2. Building Nux
You will probably need to grab the latest version of
Nux to get Unity trunk to compile:
bzr branch lp:nux
./autogen.sh --disable-examples --disable-gputests --disable-tests --prefix="$PREFIX"
Tip: Most modern desktops and laptops have several cores. You can greatly speed up the compilation by taking advantage of this. The
make command has build-in support for this which you can activate using the -jN switch where N is the number of jobs to run in parallel. A good rule of thumb is to run 2 times the number of cores on your processor. Thus, on a normal dual core computer you should run
make -j4 to minimize the compilation time.
3. Building Unity
Now grab the latest Unity code and build it:
bzr branch lp:unity
cmake .. -DCMAKE_BUILD_TYPE=Debug -DCOMPIZ_PLUGIN_INSTALL_TYPE=local -DGSETTINGS_LOCALINSTALL=ON -DCMAKE_INSTALL_PREFIX="$PREFIX"
That's it, log out and back in again and you should be running the latest Unity. Alternatively, you can run
Make sure to prepare the environment like described in step 1, then simply enter both top-level directories
bzr pull, rebuild, and reinstall.
I suggest removing and recreating the
build directory in the
unity directory, to make sure no old files are messing with your build.
5. Removing Unity
Remove the three directories
