在gdb中打印流值-C ++ [英] Print stream value in gdb - C++

问题描述

我正在尝试查看流的值(ifstream，但它应该适用于我猜想的所有流). 示例代码可能如下所示:

I'm trying to see the value of stream (ifstream, but it should work for all kind of streams I guess). The example code could look like this:

stringstream in("One Two Three Four Five");
while(in)
cout << in;

我正尝试通过以下方式进行操作，但似乎都没有效果:

I was trying to do it in following ways but none of them seems to work:

(gdb) print in
(gdb) call cout << in
(gdb) call in.getline()

...等等.

有什么办法可以看到流的价值吗?

Is there any way, to see the value of the stream?

推荐答案

您必须确保您拥有带有libstdc++库且已通过调试标志编译的软件包.

You have to make sure that you have the package with the libstdc++ library compiled with the debugging flags.

我已经安装了libstdc++6-8-dbg软件包，现在我可以在gdb中查看所有流对象数据.

I have the libstdc++6-8-dbg package installed and now I can view all the stream object data in gdb.
