I was able to get in touch with the coder who wrote this part of the app, and he thinks that possible cout and cerr are re-directed to dev/null somewhere. This was written at least 10 years ago, so his recollections are a bit hazy. Apparently the child process runs more or less like a Daemon and things like standard streams are poorly defined.
That sounds quite possible.
Quote:
He suggested adding a verbosity flag, and if that doesn't work, creating an fstream for debugging with a hard path, instead of using cout. Something like,
Code:
std::ofstream mycout("/tmp/mydebugfile");
None of this explains why it works in windows cygwin, except that the src for the child main function is rather different in windows as compared to linux.
Not really the same program at all, then. I bet that's it.
Quote:
What should I look for in the src that would be an indication that cout is going to dev/null, or somewhere other than the terminal?
Look for close( or dup( or dup2( or freopen( or STDIN_FILENO or STDOUT_FILENO or STDERR_FILENO. Also look for /dev/null, of course.

In all cases, it just outputs numbers, the location outputs 0, 1, and 2.
Crap. I forgot to do ls -l instead of ls.

I implemented a C++ program and successfully compiled and ran on my laptop. However when I copy my code to another machine (school's sun machine), it didn't run properly.
