This function requires the floating library to link. Indeed
#include "stdlib.h"
#include "stdio.h"
#include "math.h"
float fraction(void)
{
return sin(3.1415926/6); //that will err
}
int main(void)
{
fraction();
return 0;
}
errors if compiled with "tcc s.c", but is ok if you use "tcc s.c -lm".
Now, I haven't used tcc as an embedded compiler, and so don't know the
syntax needed to introduce libraries. Maybe you can dlopen() "libm.so"
before the compile -- it should find it (hopefully).
