I assume the reference to __mulodi4 stems from
#elif (defined __GNUC__ && __GNUC__ >= 5) || (__has_builtin(__builtin_mul_overflow))
template<typename T> inline bool checked_multiply(T a, T b, T& result)
{
return __builtin_mul_overflow(a, b, &result);
}
#else
in include/o3tl/safeint.hxx. Whatever the trouble with your toolchain
there, if you cannot get it solved one option would be to tweak the
#elif so that you use the #else fallback implementation of
checked_multiply instead.
