menuconfig RT_USING_CPLUSPLUS
bool "Enable C++ features"
default n
help
RT_USING_CPLUSPLUS is the master switch for enabling C++ support.
It is off by default. Once enabled, RT-Thread's build system ensures that a C++ compiler is used to compile .cpp files,
and it links C++ standard libraries (such as libstdc++ or libc++) into the final firmware.
Other C++-related configuration items that depend on it become visible and configurable.
if RT_USING_CPLUSPLUS
config RT_USING_CPLUSPLUS11
bool "Enable C++11 standard multi-threading feature support"
default n
select RT_USING_POSIX_FS
select RT_USING_POSIX_STDIO
select RT_USING_PTHREADS
select RT_USING_RTC
help
RT_USING_CPLUSPLUS11 controls whether support for multithreading features in the C++11 standard is enabled.
It is disabled by default. Once enabled, RT_USING_POSIX_FS, RT_USING_POSIX_STDIO, RT_USING_PTHREADS, and RT_USING_RTC will also be enabled.
config RT_USING_CPP_WRAPPER
bool "Enable RT-Thread APIs C++ wrapper"
default n
help
RT_USING_CPP_WRAPPER is used to enable the C++ wrapper for the RT-Thread core API.
When this option is enabled (Off by default), RT-Thread provides an additional set of C++ code that encapsulates the underlying C API using classes and objects.
config RT_USING_CPP_EXCEPTIONS
bool "Enable C++ exceptions (will increase overhead)"
default n
help
RT_USING_CPP_EXCEPTIONS is used to enable C++ exception handling.
It is disabled by default. Enabling this option pulls in the C++ exception runtime support, which typically increases
code size (flash/ROM usage), RAM consumption, and may add extra runtime overhead for stack unwinding and exception
bookkeeping. On resource-constrained or strict real-time systems, this additional overhead should be evaluated carefully
before turning the option on.
