I've seen numerous posts regarding disabling the "set but unused" warning message. I'm having the opposite problem; I can't get this warning to occur. Given the simple program
/* test.C */
int main() {
int x;
x = 1;
printf("hi\n");
return 0;
}
Compiling this with g++ 4.4.0 (the latest we have installed for official builds) and using 'Wall -Wextra' I get no compiler warning about the 'x = 1'. I even specified '-Wunused' but still no warning. I need this warning to preempt warnigns generatied by our code analysis program (Coverity).
I've seen in some other posts that g++ 4.6.0 has this warning as default, but that's not an option. Is there any way to enable this using the level of g++ we have installed?
