Build example project using C++11 with SEGGER_IDE failed

[mjt110]

Hi, in these days I want use the new feature of C++11 in nrf52 project, so I rename the "main.c" file to "main.cpp"(ble_app_blinky project), select the C++11 compiler in project options dialog,

then start building, it failed and the infomation is: 

Look forward to your reply。

Hi,

You can modify code a bit:

#ifdef __GNUC__
#ifdef __cplusplus
#define STATIC_ASSERT_SIMPLE(EXPR)      extern char (*_do_assert(void)) [sizeof(char[1 - 2*!(EXPR)])]
#define STATIC_ASSERT_MSG(EXPR, MSG)    extern char (*_do_assert(void)) [sizeof(char[1 - 2*!(EXPR)])]
#else
#define STATIC_ASSERT_SIMPLE(EXPR)      _Static_assert(EXPR, "unspecified message")
#define STATIC_ASSERT_MSG(EXPR, MSG)    _Static_assert(EXPR, MSG)
#endif
#endif

This will compile just fine.

But you will find many other areas which also need modifications.

In particular, the extensive use of Designated Initialisers  - often via complex macros.

Again, there have been posts on this before - and some contributors have shared their C++ compatible re-workings...

EDIT

See Jakub Rzeszutko's reply above - which explains some of the issues, and the scale of the task.

I am aware of these discussions. Designated Initialisers will be supported in C++ 20  I had major problem with this to change it to constructors. This adds a lot of extra code with ifdefs to our current macros.

What makes me more worry about C++ is a big warning I saw in Keil that MicroLIB is not C++ compatible.

Yes, I'm sure you are - I was addressing mjt110

sorry for confusion.
