Building

You must have a 64-bit machine for building and running the project. Always run your system updater before building and make sure you have the latest drivers.

Setup

Windows

git clone https://github.com/xenia-project/xenia.git
cd xenia
xb setup

# Build on command line (add --config=release for release):
xb build


# Pull latest changes, rebase, update submodules, and run premake:
xb pull

# Run premake and open Visual Studio (run the 'xenia-app' project):
xb devenv

# Run premake to update the sln/vcproj's:
xb premake

# Format code to the style guide:
xb format

Debugging

VS behaves oddly with the debug paths. Open the 'xenia-app' project properties and set the 'Command' to $(SolutionDir)$(TargetPath) and the 'Working Directory' to $(SolutionDir)..\... You can specify flags and the file to run in the 'Command Arguments' field (or use --flagfile=flags.txt).

By default logs are written to a file with the name of the executable. You can override this with --log_file=log.txt.

If running under Visual Studio and you want to look at the JIT'ed code (available around 0xA0000000) you should pass --emit_source_annotations to get helpful spacers/movs in the disassembly.

Linux

Linux support is extremely experimental and presently incomplete.

The build script uses LLVM/Clang 3.8. GCC should also work, but is not easily swappable right now.

CodeLite is the IDE of choice and xb premake will spit out files for that. Make also works via xb build.

To get the latest Clang on an Ubuntu system:

sudo -E apt-add-repository -y "ppa:ubuntu-toolchain-r/test"
curl -sSL "http://llvm.org/apt/llvm-snapshot.gpg.key" | sudo -E apt-key add -
echo "deb http://llvm.org/apt/precise/ llvm-toolchain-precise main" | sudo tee -a /etc/apt/sources.list > /dev/null
sudo -E apt-get -yq update &>> ~/apt-get-update.log
sudo -E apt-get -yq --no-install-suggests --no-install-recommends --force-yes install clang-4.0 clang-format-4.0

You will also need some development libraries. To get them on an Ubuntu system:

sudo apt-get install libgtk-3-dev libpthread-stubs0-dev liblz4-dev libx11-dev libvulkan-dev libc++-dev libc++abi-dev

In addition, you will need the latest Vulkan libraries and drivers for your hardware.

Linux NVIDIA Vulkan Drivers

You'll need to install the latest NVIDIA drivers to enable Vulkan support on Linux.

First, remove all existing NVIDIA drivers:

sudo apt-get purge nvidia*

Add the graphics-drivers PPA to your system:

sudo add-apt-repository ppa:graphics-drivers
sudo apt update

Install the NVIDIA drivers (newer ones may be released after 387; check online):

sudo apt install nvidia-387

Either restart the computer, or inject the NVIDIA drivers:

sudo rmmod nouveau
sudo modprobe nvidia

Running

To make life easier you can use --flagfile=myflags.txt to specify all arguments, including using --target=my.xex to pick an executable. You can also specify --log_file=stdout to log to stdout rather than a file.
