On Linux, Debugging a C++ application with gdb in Eclipse CDT, how to input something to stdin?

Question

On Linux, I am trying to debug a C++ application with gdb in Eclipse CDT.

For example the application applic.exe takes some command line arguments arg1 and arg2 and it expects some data on stdin (say, taken from a file input.txt).

Normally, to run the application in the console I would do this:

cat input.txt | applic.exe arg1 arg2

Using gdb in the console I can do:

gdb applic.exe
(gdb) run applic.exe arg1 arg2 < input.txt

Is it possible to do that with gdb in Eclipse? I know how to specify the arguments (and the environment) in the Eclipse Debug Configurations, but what about stdin?

I am not sure if that can be done, in the run configuration there is an option for specifying an output file, but for input it says that it needs to have a console attached. — fortran, Jan 13 '12 at 14:44

There is Console tab in Eclipse (at the bottom of IDE) you can put your data here.

Make sure you select the gdb console from the consoles that are available. – Grammin Jan 13 '12 at 14:34
I think the op is asking for an automatic way of doing that, not copying and pasting every time (it might be a very large input file!) – fortran Jan 13 '12 at 14:36
Then what about passing file name as a parameter, and open it for read inside the program? – Yodo Jan 13 '12 at 17:30
Yes, that can used as a workaround. But I would have preferred not to. – user1069609 Jan 16 '12 at 09:42

Instead of entering the redirection in the arguments tab, append it to the executable file name in the debug configuration.
