I use this command to compile the code below:
g++ -ansi -pedantic -Wall -Wextra myfile.cpp
I want to get a warning int64_t is converted into int. But there is no any warning at all. How can I achieve this?
My g++ version is 4.6.1.
//file:myfile.cpp
#include <iostream>
using namespace std;
int main()
{
int64_t yy = 10;
int size = yy;
cout << size << endl;
}
Try -Wconversion; due to the large amount of noise this warning tends to produce, it’s not part of -Wall
