How to use the command of rbreak correcly?

我想在Test:：Say((处设置中断。break-Test:：Say((的方法可以做到。但是，rbbreak-TestSay(

(gdb(rbbreak测试：：Say((找不到名为"main.cpp:'Test:：Say(("的命名空间、类、结构或联合的成员提示：尝试'main.cpp:'Test:：Say(('或'main.cpp：'Test:(('(注意前导单引号。(
   class Test
    {
    public:
            Test()
            {
            }
            void Say()
            {
                    printf("Hello word!");
            }
    };

    int main ()
    {
            Test a;
            a.Say();
            getchar();
            return 0;
    }

我建议将gdb升级到最新版本。我用gdb 7.2版复制了你的错误：

然而，在最近的gdb 7.9版本中，rbreak以exected:的方式工作
