Hello everybody, I'm having severe problems with native threads. Not only I can't get them to work with the Graphics module, I can't get them to work at all. I'm using a fresh Debian 3.0r0. I've recompiled Ocaml 3.06 with '-with-pthread' option. Shouldn't the following code $ cat toto.ml open Thread let _ = let code1 () = let x = ref 0 in while true do incr x; Printf.printf "alpha %d\n" !x; flush stdout done in let thread1 = Thread.create code1 () in while true do () done compiled with $ ocamlopt.opt -thread unix.cmxa threads.cmxa toto.ml -o toto and run as $ ./toto give me something like alpha 0 alpha 1 alpha 2 alpha 3 alpha 4 alpha 5 alpha 6 ... ? Instead, the program doesn't output anything, and when I hit Ctrl-C, it leaves some processes running, which can only be killed with SIGKILL. The program works when compiled as bytecode. System info : $ uname -a Linux gogol 2.4.18 #1 Thu Aug 22 20:42:28 CEST 2002 i586 unknown $ ls -l /lib/libpthread* -rw-r--r-- 1 root root 102172 Apr 28 11:57 /lib/libpthread-0.9.so However, even in bytecode, when I use the Graphics module, some subprocesses refuse to die when I interrupt the main program. Any clues ? Thanks very much. -- Berke Durak ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
