I have not tried this, but you may try to debug it using gdbserver.

Now you can start your app on the console  (I am not sure what 
commandline gdbserver takes / please double check)
DUMMY INSTRUCTION
gdbserver -host ip:port  yourapp

gdbserver will hold your app right at the start.
Your app should be able to read and write to the console from which you 
started it.
You can then start debugging in the IDE.


Going one step further, if you are real lucky, you can put the above 
gdbserver line into a script, and actually run it as cgi in a webserver 
(if the webserver does not timeout/kill it)
