What is it?

OpenSpades is a compatible client of Ace of Spades 0.75.

  • Can connect to a vanilla/pyspades/pysnip server.
  • Uses OpenGL/AL for better visuals.
  • Open source, and cross platform.


On Linux

GCC 4.8 / Clang 3.2 or later is recommended because OpenSpades relies on C++11 features heavily.

  1. Install dependencies:

    On Debian-derived distributions: sudo apt-get install pkg-config libglew-dev libcurl3-openssl-dev libsdl2-dev libsdl2-image-dev libalut-dev (because of a bug in some distributions, you might also have to install more packages by sudo apt-get install libjpeg-dev libxinerama-dev libxft-dev)

    On other distributions: Install corresponding packages from your repository (or compile from source).

  2. Download & install SDL-2.0.2

    tar -zxvf SDL2-2.0.2.tar.gz
    cd SDL2-2.0.2/
    ./configure && make && sudo make install
    cd ../

    Additional dependencies may be required.

  3. Download & install SDL2_image-2.0.0

    tar -zxvf SDL2_image-2.0.0.tar.gz
    cd SDL2_image-2.0.0/
    ./configure --disable-png-shared && make && sudo make install
    cd ../

    Additional dependencies may be required.

  4. Clone OpenSpades repository:

    git clone && cd openspades

  5. Create directory in cloned/downloaded openspades repo and compile:

    cmake .. -DCMAKE_BUILD_TYPE=Release && make
  6. Install openspades:

    sudo make install

    note: make install broken in old releases

  7. Get shared files:

    • If you compiling certain release (0.0.10 for example):

      Download windows binary of OpenSpades from, extract it, and copy the .pak files inside Resources directory into /usr/local/share/games/openspades/Resources or $XDG_DATA_HOME/openspades/Resources. If there were some files in these directories, you probably should remove them.

      note: use ~/.openspades/Resources in old releases.

    • If you compiling straight from source (git clone):

      All needed resources would be downloaded while make install, so no need to worry.

      If you didn't launched make install, you can install resources manually. See Resources/PakLocation.txt to find out where get latest shared files. Download, extract, and place them into /usr/local/share/games/openspades/Resources or $XDG_DATA_HOME/openspades/Resources

  8. Launch:

    openspades or cd $REPO_DIRECTORY; ./ and enjoy

On Windows (with visual studio)

  1. Get CMake, Visual Studio 2013 (Express) or Visual Studio 2015 (not very supported), and the OpenSpades source. Official: Unofficial:
  2. Extract or checkout the source (all examples will assume E:/Projects/openspades, update paths in the examples to reflect yours)
  3. Get (pre-compiled) copies of fltk, glew, curl, sdl2 and zlib, and place them in E:/Projects/openspades/Sources/Externals. See the file E:/Projects/openspades/Sources/Externals/readme.txt for details (and a pre-compiled set of libraries, make sure to pick the right one for your version of VS).
  4. Run CMake, using the paths: Source: E:/Projects/openspades Binaries: E:/Projects/openspades/OpenSpades.msvc For your convenience, create the directory: E:/Projects/openspades/OpenSpades.msvc/os.Resources, extract the resources (.pak files) to this dir, set OPENSPADES_RESDIR to point to this directory. (Run CMake again, now when running debug builds openspades will also read resources from this dir)
  5. Open E:/Projects/openspades/OpenSpades.msvc/OpenSpades.sln in Visual Studio.

On Mac OS X (with Xcode)

  1. Get the latest version of Xcode and OpenSpades source.
  2. Download and install SDL2 development libraries for OS X to /Library/Frameworks.
  3. Download and install SDL2_image development libraries for OS X to /Library/Frameworks.
  4. Download OS X release of OpenSpades, show the package contents, and copy libysrspades.dylib to the root of OpenSpades source tree.
  5. Open OpenSpades.xcodeproj and build.
