Question

Question cribbed from here:

I have a program that takes input from stdin and also takes some parameters from command line. It looks like this:

cat input.txt > myprogram -path "/home/user/work" 

I try to debug the code with gdb inside emacs, by M-x gdb, I try to load the program with the command:

gdb cat input.txt > myprogram -path "/home/user/work" 

However, gdb does not like it.

Unfortunately I don’t understand the solution and am not sure what to do beyond compiling with the -g option and running the command M-x gdb.

Answer 1

If you were doing it from a shell you’d do it like this:

% gdb myprogram gdb> run params ... < input.txt 

This seems to work within emacs too.
