Question

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;

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()

… and so on.

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

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

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