error: #59: function call is not allowed in a constant expression

C. J.

Hi,
I am trying to compile a example code from Atmel, which was written for Atmel Studio IDE, GCC or IAR compilers, and getting the following error:

error: #59: function call is not allowed in a constant expression

This is an similar example of the code:

const sam_abc xy_settings = {function_yz(), 111, 250 };

- sam_abc is a struct
- function_yz() is the function which causes the error

I am using µVision V4.54.0.0 (C Compiler: Armcc).

How could I solve this problem?
Can someone please help me. Thanks in advance.

    In my case, I added "GNU extensions" ticked in Target Build Options - C/C++ , removed this error.

    Here's my new settings screenshot..

    Just by disabling this GNU extensions, the error re-appears.
