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。

Thanks for reply! I modify the code like Jakub Rzeszutko  said, it works and the "app_util.h" has no error now. But,like awneil said, there are many other areas which also need modifications—— The linker can not find ”nrf_pwr_mgmt_init“ and ”nrf_pwr_mgmt_run“：

When I temporarily comment out these two lines of code，the project build successfully and I can use lambda in main function.

Why the linker can not find ”nrf_pwr_mgmt_init“ and ”nrf_pwr_mgmt_run“?

You said you've renamed "main.c" to "main.cpp" - but have you also renamed all the other *.c source files to *.cpp?

Without that, they will still be built as 'C' - not C++ - and, therefore, linker errors are to be expected ...

Only renamed "main.c"。I checked the code in ”nrf_pwr_mgmt.h“ ( ”nrf_pwr_mgmt_init“ and ”nrf_pwr_mgmt_run“ defined in this header), and I found that there's no "ifdef _cplusplus_ extern "C"" preprocessor at the begining of the head file, after I append these code to this file, the entire project can be built seccessfully.
