RE: Using C++ std::exceptions with NCS

Hi Øyvind,

thanks for your suggestion. It's definitely a good place to get Zephyr related help.

For those that might run into the same issue, here's my solution:

In prj.conf you need the C++ and exceptions related stuff:

...
CONFIG_CPLUSPLUS=y
CONFIG_LIB_CPLUSPLUS=y

CONFIG_NEWLIB_LIBC=y
CONFIG_EXCEPTIONS=y
CONFIG_NEWLIB_LIBC_NANO=n
...

To prevent the linker error, I had to implement following function:

void exit(int reason) {
  printk("EXIT %d", reason);
  while (1)
    ;
}

Now the code compiles without error and the exceptions are being catched. But Interestingly exit() is being called.

Hello Oliver,

This is unfortunately nothing we can assist with as this is part of the Zephyr RTOS. Please reach out to the Zephyr community through their Discord channel.

Kind regards,
Øyvind
