Code::Blocks error "rad2deg does not name a type" error "rad2deg was not declared in this scope" C++23

Question

I know for a fact this code is written correctly due to testing this on my Linux machine. No matter what I have done the error persists. I am new to Windows 10 and Code::Blocks, any help regarding setting up Code::Blocks properly or the issue at hand would be greatly appreciated.

I have no idea what I can do since the code is exactly the same. I am unfamiliar with Code::Blocks and I assume I must have failed to configure something. Any help would be awesome, thank you.

Linux:

//g++ main.cpp -Os -std=c++23 -Wall -Wextra; ./a.out
#include <iostream>
#include <cmath>

int32_t main() {
    auto rad2deg = [](double rad) {return rad * 180.0 / std::acos(-1.0);};
    std::cout << rad2deg(6.2) << '\n';
}

Windows:

#include <iostream>
#include <stdint.h>
#include <stdlib.h>
#include <stdio.h>
#include <ostream>
#include <cmath> 


int32_t main() {
    auto rad2deg = [](double rad) {return rad * 180.0 / std::acos(-1.0);};
    std::cout << rad2deg(6.2) << '\n';
}

EXPECTED OUTPUT:

355.234

ACTUAL OUTPUT:

error: 'rad2deg' does not name a type
error: 'rad2deg' was not declared in this scope

Answer 1

I got it to work by changing the compiler settings under Settings -> Compiler and changing the Compiler Flag to c++17 instead of c++98 (LOL)
