comment "Basic CXX Support"
config C99_BOOL8
bool "sizeof(_Bool) is 8-bits"
default n
---help---
This setting means (1) your C++ compiler has sizeof(_Bool) == 8, (2)
your C compiler supports the C99 _Bool intrinsic type, and (2) that
the C99 _Bool type also has size 1.
config HAVE_CXX
bool "Have C++ compiler"
default n
---help---
Toolchain supports C++ and CXX, CXXFLAGS, and COMPILEXX have been
defined in the configurations Make.defs file.
if HAVE_CXX
config HAVE_CXXINITIALIZE
bool "Have C++ initialization"
default LIBCXX || UCLIBCXX
---help---
The platform-specific logic includes support for initialization
of static C++ instances for this architecture and for the selected
toolchain (via up_cxxinitialize()).
config CXX_EXCEPTION
bool "Enable Exception Support"
default LIBCXX || UCLIBCXX
config CXX_LIBSUPCXX
bool "Have libsupc++ (required)"
default LIBCXX || UCLIBCXX
---help---
Select if your toolchain provides libsupc++. This option is required
at present because the built-in libsupc++ support is incomplete.
comment "LLVM C++ Library (libcxx)"
config LIBCXX
bool "Build LLVM libcxx (must be installed)"
default n
select CLOCK_MONOTONIC
select LIBC_WCHAR
select LIBC_LOCALE
---help---
If you have installed libcxx into the NuttX source tree, then it can
be built by selecting this option. See the README.txt file in the
libcxx package for information on installing libcxx.
comment "uClibc++ Standard C++ Library"
config UCLIBCXX
bool "Build uClibc++ (must be installed)"
default n
---help---
If you have installed uClibc++ into the NuttX source try, then it can
be built by selecting this option. See the README.txt file in the
uClibc++ packet for information on installing uClibc++.
if UCLIBCXX
config UCLIBCXX_BUFSIZE
int "IO Stream/Container Buffer Size"
default 32
