Compile nRF5 SDK with C++

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.

Thanks, but this does not solve the problem. Even, if I only use the nrfx_uart.c, which requires nrfx_prs.c, I get the errors mentioned above. Compiling nrfx_prs.c fails with the following errors:

You need to explicitly initialize the struct members in the correct order rather than using the initialization macros. It should look something like the following:

static nrf_drv_uart_t uart = {
    .inst_idx = 0, 
    .uarte = { 
        .p_reg = NRF_UARTE0, 
        .drv_inst_idx = NRFX_UARTE0_INST_IDX
        }
    }

Hopefully I'm close, the UART driver has a couple more layers of macros that need to be expanded than the other peripherals I've worked with.
