config REQUIRES_FULL_LIBCPP
bool "Require complete C++ standard library"

help
Indicates that a full C++ standard library is required, either by
a subsystem or an application. This will also include a full C
library implementation.

Selected when the target has at least one C++ library that offers a
complete implementation and which would be selected when
REQUIRES_FULL_LIBCPP is set.

Build with the minimal C++ library provided by Zephyr.
The Zephyr minimal C++ library only provides a very limited subset
of the standard C++ library and is mainly intended for use with the
applications that do not require the Standard Template Library (STL).

help
This option used to be necessary to instruct the Zephyr kernel to
call 'int main(void)' instead of the old Zephyr default, 'void
main(void)'.
As the Zephyr type now matches the C++ required type, this option
is no longer necessary.
