这是我要设置的代码部分：

void *sync(void *ptr) {
  vector<short> gen = generate_sygnal();

我用调试标志构建我的程序，这是我在 gdb 中所做的：

(gdb) break daemon.cxx:sync
break daemon.cxx:sync
Breakpoint 1 at 0x804d080: file /home/username/projects/armd/complex/daemon/daemon.cxx, line 160.
(gdb) watch gen
watch gen
No symbol "gen" in current context.
(gdb) run

(gdb)

那么如何使用 gdb 检查我的 gen 值呢？即使我需要完整的向量值堆栈。

再插入一行，sync()以便变量实际上在范围内（使用 GDB 的next命令）。
