Hi,
Sorry,
for the last question! I solved it just after posting. In the compiled
version of the code I sent the process terminated before the thread got a
chance to execute the display... I added a (thread-sleep! 1) at the end
and I saw the message appear.
I will look further
in my code to see why I am not getting the expected outputs in the console from
my threads...

Subject: [gambit-list] IO and
threads question
Hi,
I have a strange problem with input/output and threads using
GambitC-4b22 (WinXP/MINGW). I tried to isolate it.
It can be basically reproduced by running the following code
in the interpreter:
(define
(main)
(let ((t (make-thread
(lambda ()
(display "\n\n\n hello world!\n\n\n")
(force-output)))))
(thread-start! t)))
(main)
Which does the expected thing: display the “hello
world” message in the console.
If I compile the above program to an executable it
doesn’t display the message anymore.
In my real context, I am using a mutex and many threads are
writing a trace to the console. In the compiled version I get no traces…
What am I missing?
Thank you,
