I am trying to run a simple floating point c code on pulpino but i am facing an issue where floats are not being printed.
here is the code that i am trying to run :
#include <stdio.h>
int main() {
float a =4.2;
float b = 3.1;
float c;
float d;
c = a+b ;
d = a-b ;
printf("Toplam=%f",c);
printf("Fark=%f",d );
return 0;
}
`error: implicit conversion from 'float' to 'double' when passing argument to function [-Werror=double-promotion]`
I understand that the error is originating because printf implicitly converts float to double when we use %f
after removing that flag even though the make is successful ,The floats are not visible . Previously only Toplam= was printed without the floats now i only see garbage characters no matter what i print `Æ÷.`
If i remove all other flags and only keep the mfpdouble=float flag then i am getting `error: insn does not satisfy its constraints:
}

I have no clue where i am going wrong here would appreciate any help and advice on what direction i should take to solve this issue

and here is my cmake configuration
I am using the https://github.com/pulp-platform/ri5cy_gnu_toolchain compiler with the FPU. since i am adding the -Werror=double-promotion flag i am getting an error
