|
|
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.

|
|
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.
