The YGOpen project aims to create a free-as-in-freedom, cleanly-engineered Yu-Gi-Oh! Official Card Game simulator, complete with client and server support. This server supports EDOPro clients and dynamically links to that core.

• Git (or you can download the zip from GitHub)

• premake5: extract this into the working directory

• Platform C++ toolchain

  • Windows: Visual Studio
  • macOS: GCC (Clang does NOT support C++14/C++17 standard library)
  • Linux: GCC 8+ or Clang 5+

• On macOS, we use Homebrew to get dependencies. Install gcc with brew install gcc

• On Windows, set up vcpkg

Build ocgcore as a shared library and put it in the folder where you will move the server executable.

On Linux, get these dependencies from your package manager or build from source: asio nlohmann-json sqlite3.

On Windows, invoke vcpkg to build dependencies from source: vcpkg install --triplet x86-windows-static asio nlohmann-json sqlite3.

On macOS, install dependencies with brew install asio nlohmann-json sqlite3.

On Linux, do ./premake5 gmake2 && make -Cbuild for a debug build. Specify config=release for a release build and make sure to set your compiler with CXX=

On Windows, do ./premake5.exe vs2017 or ./premake5.exe vs2019 to create the solution files and then build from the generated Visual Studio .sln file in build.

On macOS, do ./premake5 gmake2 && make -Cbuild CXX=g++-9 for a GCC debug build, assuming you installed GCC with brew.
