## Appendix: Installing and Running Tests

#### Installing the Fiber library

As Fiber is not yet officially part of Boost, it is necessary to embed it in an existing Boost source tree.

The downloaded Fiber library can be placed into an existing Boost source tree by moving the top-level Fiber directory to `libs/fiber` under the top-level Boost directory, then further moving `libs/fiber/include/boost/fiber` (in other words, the Fiber library's `include/boost/fiber` directory) to `boost/fiber` under the top-level Boost directory.

On a Posix system such as Linux or OS X, you may use symlinks instead.

Create a symlink from the Boost directory's `libs/fiber` to the top-level Fiber directory, e.g.:

    cd ~/boost_1_61_0
    ln -s ~/boost-fiber-master libs/fiber

Then create a symlink from the Boost directory's `boost/fiber` to the Fiber library's `include/boost/fiber` directory:

    cd boost
    ln -s ../libs/fiber/include/boost/fiber fiber

For some versions of the Boost.Build system, it was important to use a relative symlink of that form for `boost/fiber`.

#### Running Tests

Once the Fiber library has been overlaid (or symlinked) into the Boost source tree this way, the Boost.Build system can build it like any other Boost library. In particular:

    cd ~/boost_1_61_0
    ./bootstrap.sh
    ./b2 libs/fiber/test

On Windows, the commands would look more like:

    cd /D %HOMEDRIVE%%HOMEPATH%\boost_1_61_0
    bootstrap
    b2 libs\fiber\test
