^^^^^^^^^^^^^^
This is the mandatory, "Hello, World!!" example. It is little more
than examples/null with a single printf statement. Again useful only
than examples/null with a single printf statement. Really useful only
for bringing up new NuttX architectures.
NuttX configuration settings:
CONFIG_EXAMPLE_HELLOXX_NOSTATICCONST - Set if system does not support
static constructors.
CONFIG_EXAMPLE_HELLOXX_NOSTACKCONST - Set if the systgem does not
support constructionof objects on the stack.
examples/helloxx
^^^^^^^^^^^^^^^^
This is C++ version of the "Hello, World!!" example. It is intended
only to verify that the C++ compiler is function, that basic C++
only to verify that the C++ compiler is functional, that basic C++
library suupport is available, and that class are instantiated
correctly.
NuttX configuration settings:
CONFIG_EXAMPLES_HELLOXX_BUILTIN -- Build the helloxx example as a
"built-in" that can be executed from the NSH command line.
CONFIG_EXAMPLE_HELLOXX_NOSTATICCONST - Set if system does not support
static constructors.
CONFIG_EXAMPLE_HELLOXX_NOSTACKCONST - Set if the system does not
support construction of objects on the stack.
Also needed:
CONFIG_HAVE_CXX=y
And you may have to tinker with the following to get libxx to compile
properly:
CONFIG_CXX_NEWLONG=y or =n
The argument of the 'new' operators should take a type of size_t. But size_t
has an unknown underlying. In the nuttx sys/types.h header file, size_t
is typed as uint32_t (which is determined by architecture-specific logic).
But the C++ compiler may believe that size_t is of a different type resulting
in compilation errors in the operator. Using the underlying integer type
Instead of size_t seems to resolve the compilation issues.
