[GRPC Netplay]

This project uses GRPC as a transport mechanism to implement a deterministic lockstep netplay for the mupen64plus emulator.

Building - Mac OS

Install dependencies. This assumes you use homebrew as a package manager:

# Install necessary packages
brew install cmake automake libtool automake autoconf gettext sdl sdl2 pkg-config freetype libpng

From the App Store, install the latest version of Xcode (necessary to get the MacOS Platform command line tools).

Clone and build the repo:

git clone https://github.com/water-works/mupen64plus-netplay.git
cd mupen64plus-netplay

# Pull down all dependencies.
git submodule update --init --recursive

# Build
cmake .
make -j8

Run tests. Note the DYLD_FALLBACK_LIBRARY_PATH is necessary because we don't build in the location of many libraries. This is a known issue:

cd netplay
DYLD_FALLBACK_LIBRARY_PATH=$(pwd)/../usr make test

Building - Linux (Debian/Ubuntu)

Install dependencies:

sudo apt-get install build-essential git cmake libsdl2-dev autoconf \
                     libtool shtool libpng-dev libfreetype6-dev nasm

Clone and build the repo:

git clone https://github.com/water-works/mupen64plus-netplay.git
cd mupen64plus-netplay

# Pull down all dependencies.
git submodule update --init --recursive

# Build
cmake .
make -j8

Run tests:

cd netplay
make test
