Let me start by saying I'm having a hell of a time and I'm beginnging to think there is some problem with the implementation of Runtime.exec(). With that being said if anyone has an idea, a clue or even just want's to babble about this, please respond.
You can see more about what I'm trying to accomplish and what I've tried here.
http://www.javaranch.com/ubb/Forum34/HTML/001360.html Anyway this is what I'm trying now.
I wrote a little shell script to that calls an executable with one argument. I just hardcoded the argument in the script to see if I could get it to work.
So I call me little shell script from a command prompt and voila, it works exactly how I would expect it to. The executable runs with the argument and I get output in the directory I called the script from. Everything is normal, predictable and good.
Now I try to execute the script with Runtime.exec() and it blows up: ERR>/usr/local/vklab/bin/Runrate: line 3: 11340 Segmentation fault (core dumped) /usr/local/vklab/rate/Rate /usr/local/vklab/rate/infiles/sct.dat
Segmentation fault, fun fun
I thought maybe I could open a shell with Runtime.exec() and then try the script with that.
Like so:
And the thing blows up again, Segementation Fault yada yada.
From a prompt, runs great, from Runtime.exec(), blows up. What to do?
Its not like I have a way to step through whatever happens once I pass it to Runtime.exec()? Do I? If no one has an idea for a solution, does anyone at least have an idea of an approach to discover the problem?
regards,
Andrew
