Hi,
Turning on -Werror so the warnings don't scroll by.
$ cat test.c
#include <stdio.h>
int main(void)
{
int x;
x = printf("hello, world\n");
return 0;
}
$
$ gcc-4.6 -Wall -Werror test.c; echo $?
test.c: In function ‘main’:
test.c:5:6: warning: variable ‘x’ set but not used [-Wunused-but-set-variable]
0
$ gcc-4.6 -Wunused-but-set-variable -Werror test.c; echo $?
test.c: In function ‘main’:
test.c:5:6: warning: variable ‘x’ set but not used [-Wunused-but-set-variable]
0
$ gcc-4.6 -Werror=unused-but-set-variable test.c; echo $?
test.c: In function ‘main’:
test.c:5:6: error: variable ‘x’ set but not used
[-Werror=unused-but-set-variable]
cc1: some warnings being treated as errors
1
I would have expected all three to error out.
Known problem?
Jonathan
