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] ..

2. Build it!

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

Recent Releases

yaml-cpp 0.6.0 released! This release requires C++11, and no longer depends on Boost.

yaml-cpp 0.3.0 is still available if you want the old API.

The old API will continue to be supported, and will still receive bugfixes! The 0.3.x and 0.4.x versions will be old API releases, and 0.5.x and above will all be new API releases.
