.. option:: LIBCXX_ENABLE_FILESYSTEM:BOOL
- **Default**: ``LIBCXX_ENABLE_EXPERIMENTAL_LIBRARY``
+ **Default**: ``ON``
+
+ Build filesystem as a standalone library libc++fs.a.
+
+.. option:: LIBCXX_INSTALL_FILESYSTEM_LIBRARY:BOOL
- Build filesystem as part of libc++experimental.a. This allows filesystem
- to be disabled without turning off the entire experimental library.
+ **Default**: ``LIBCXX_ENABLE_FILESYSTEM AND LIBCXX_INSTALL_LIBRARY``
+ Install libc++fs.a alongside libc++.
.. _ABI Library Specific Options:
$ export LD_LIBRARY_PATH=<libcxx-install-prefix>/lib
$ ./a.out # Searches for libc++ along LD_LIBRARY_PATH
+
+Using ``<filesystem>`` and libc++fs
+====================================
+
+Libc++ provides the implementation of the filesystem library in a separate
+library. Users of ``<filesystem>`` and ``<experimental/filesystem>`` are
+required to link ``-lc++fs``.
+
+.. note::
+ Prior to libc++ 7.0, users of ``<experimental/filesystem>`` were required
+ to link libc++experimental.
+
+.. warning::
+ The Filesystem library is still experimental in nature. As such normal
+ guarantees about ABI stability and backwards compatibility do not yet apply
+ to it. In the future, this restriction will be removed.
+
+
Using libc++experimental and ``<experimental/...>``
=====================================================
:ref:`Building Libc++ <build instructions>` and
:ref:`libc++experimental CMake Options <libc++experimental options>`.
+Note that as of libc++ 7.0 using the ``<experimental/filesystem>`` requires linking
+libc++fs instead of libc++experimental.
+
