+Dependencies
+^^^^^^^^^^^^

+1. The C++ runtime support is provided by GCC libgcc_eh.a and libsupc++.a
+  libraries.
+2. NuttX C++ support
+3. Math library
+4. TLS support is currenly provided only under RGMP

+NuttX Configuration File Changes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In order to build libxx (and hence libxx/uClibc++), C++ support must be
+enabled.  The following must be defined in your NuttX configuration file.
+
+  CONFIG_HAVE_CXX=y
+
+There are many ways to provide math library support (see nuttx/README.txt).
+If you choose to use the NuttX math library, that is enabled as follows:
+
+
+  CONFIG_LIBM=y
+
+The math libraries depend on the float.h header file that is normally
+provided by your tooltchain.  A dummy (and probably wrong) fload.h file
+can be installed by setting:
+
+  CONFIG_ARCH_FLOAT_H=y
