问题描述
我写了一个简单的test.cc如下:
I wrote a simple test.cc as follows:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world" << endl;
return 0;
}
我编译了:
g++ -g test.cc -o test.o
我运行了 gdb 并在 "Hello world" 行放了一个断点:
I ran gdb and put a breakpoint at the "Hello world" line:
$ gdb test.o
(gdb) b 7
(gdb) c
然后 gdb 停在 "Hello world" 行，但是当我运行时
Then gdb stops at the "Hello world" line, but when I run
(gdb) s
无法进入 cout 函数.所以我的问题是，我怎样才能进入 cout 函数?
It fails to step into the cout function. So my question is, how can I step into the cout function?
推荐答案
如果没有链接到带有调试信息的标准库版本，它不知道如何进入库；它只能越过它(即运行直到控制权返回到带有调试信息的代码).
If it wasn't linked against a version of the standard library with debugging information, it doesn't know how to step into the library; it can only step over it (that is, run until control returns to the code with the debugging information).
请查阅您系统的文档以了解如何安装标准 C 和 C++ 库的调试版本.
Consult the documentation for your system to find out how to install the debug version of the standard C and C++ libraries.
