# Testing / `cxxtest` C++ STL

This is a test of the C++ standard library. At present a port of the uClibc++
C++ library is available. Due to licensing issues, the uClibc++ C++ library is
not included in the NuttX source tree by default, but must be installed (see the
`README.txt` file in the uClibc++ download package for installation).

The uClibc++ test includes simple test of:

- iostreams,
- STL,
- RTTI, and
- Exceptions

## Example Configuration Options

- `CONFIG_TESTING_CXXTEST=y` – Enables the example

## Other Required Configuration Settings

Other NuttX setting that are required include:

- `CONFIG_HAVE_CXX=y`
- `CONFIG_HAVE_CXXINITIALIZE=y`
- `CONFIG_UCLIBCXX=y` or `CONFIG_LIBCXX=y`

Additional `uClibc++/libcxx` settings may be required in your build environment.
