Problems using math functions and double.

[jaslob]

I'm new to Zephyr and did another small test application.
I'm able to build the application but when I try to run the application I receive an error.
I can't use the math functions and have also trouble just adding two doubles. Why is that? I guess I have problems with the configuration. Thanks for your help.

main.cpp

#include <zephyr.h>
#include <sys/printk.h>
#include <math.h>
#include <stdio.h>
#include <iostream>

int main()
{
    double angle = 90;
    double rad;
    double sine;
    double cosine;
    
    const double Pi = 3.141592653;
    
    rad = angle * Pi / 180;
    sine = sin(rad);
    cosine = cos(rad);
    
    std::cout << "Angle: " << angle << "\nSine: " << sine << "\nCosine: " << cosine << std::endl;
    
    return 0;
}

prj.conf

CONFIG_NEWLIB_LIBC=y
CONFIG_CPLUSPLUS=y

CONFIG_STD_CPP17=y

Try setting CONFIG_MAIN_STACK_SIZE=2048

Thanks but that didn't help.

[stephanosio]

Try setting:

CONFIG_MAIN_STACK_SIZE=2048
CONFIG_FPU=y
CONFIG_SSE=y

[jaslob]

Thank you so much. That helped.

Closing this as it seems solved. Thanks @stephanosio
