How to Build

yaml-cpp uses CMake to support cross-platform building. Install CMake (Resources -> Download) before proceeding. The basic steps to build are:

Note: If you don't use the provided installer for your platform, make sure that you add CMake's bin folder to your path.

1. Navigate into the source directory, create build folder and run CMake:

mkdir build
cd build
cmake [-G generator] [-DYAML_BUILD_SHARED_LIBS=on|OFF] ..
  • The generator option is the build system you'd like to use. Run cmake without arguments to see a full list of available generators.

    • On Windows, you might use "Visual Studio 12 2013" (VS 2013 32-bits), or "Visual Studio 14 2015 Win64" (VS 2015 64-bits).
    • On OS X, you might use "Xcode".
    • On a UNIX-like system, omit the option (for a Makefile).
  • yaml-cpp builds a static library by default, you may want to build a shared library by specifying -DYAML_BUILD_SHARED_LIBS=ON.

  • For more options on customizing the build, see the CMakeLists.txt file.

2. Build it!

  • The command you'll need to run depends on the generator you chose earlier.

Note: To clean up, just remove the build directory.

Recent Releases
