Compile nRF5 SDK with C++

[Kai]

Hi,

I am programming for an nRF52840 chip. I am using Keil uVision with the ARM compiler in version 5. My codebase is in C++, this is why I have the Misc control "--cpp".

I want to use the uart library. But I do get compile errors, such as:

  static nrf_drv_uart_t app_uart_inst = NRF_DRV_UART_INSTANCE(APP_UART_DRIVER_INSTANCE);
C:\nordic\sdk_16.0\components\libraries\uart\app_uart.c(90): error:  #29: expected an expression

What do I have to do get rid of this? What I do understand is, that nRF5 SDK code base uses aggregate initialization for its structs, which the compiler does not like. Is there an SDK version that is C++ compatible? 

Changing the ARM compiler to version 6 yields errors such as.
C:\Keil_v5\ARM\CMSIS\Include\core_cmFunc.h(602): error: unknown register name 'vfpcc' in asm

Kind regards,
Kai

I was able to compile the nrf5 SDK with the ARM compiler 6 instead of 5, the errors with 'vfpcc' resolve, if the CMSIS Core is selected as Run-Time Environment in Keil. My setup used some default CMSIS, which I do not know where it is located.
