Re: software dectalk 1.0

[Mario Lang <mlang@xxxxxxxxxxx>]

Bart, what you described is the same thing that is happening here.

I'm also running tcl8.3, glibc 2.3.1 and gcc 2.95.4

If I strace tcl dtk-soft, it stops at a rt_sigsuspend call like this:
...
rt_sigsuspend([] <unfinished ...>
--- SIGRTMIN (Unknown signal 32) ---
<... rt_sigsuspend resumed> )           = -1 EINTR (Interrupted system call)
sigreturn()                             = ? (mask now [RTMIN])
rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0
rt_sigsuspend([]

the `say' binary works as expected, license code was entered correctly,
and a small talking hello-world program in C links and works as
expected.  So the .so files seem to be fine.  Could it be that the
tcl interpreter and the way dtk creates alot of threads collide with
each other?

#include <stdio.h>

typedef void * LPTTS_HANDLE_T;
typedef long DWORD;

int main() {
  int status;
  LPTTS_HANDLE_T dtkHandle;
  unsigned int  devNo = 0;
  DWORD devOptions = 0;
  DWORD dwFlags = 0;
  DWORD force = 1;
  devOptions |= 1;
  /*  devOptions |= WAVE_OPEN_SHAREABLE;*/
  fprintf(stderr, "Calling tts startup.\n");
  status = TextToSpeechStartup(&dtkHandle, devNo, devOptions, NULL, NULL);
  fprintf(stderr, "tts startup returned %d\n", status);
  if (dtkHandle == NULL) { 
    fprintf(stderr, "Could not open text-to-speech engine\n");
    return 1;
  }
  if (TextToSpeechSpeak(dtkHandle,"Hello World!", dwFlags) != 0) {
    fprintf(stderr,"Internal tts error\n");
    return 2;
  }
  if (TextToSpeechSpeak(dtkHandle,"", force) != 0) {
    fprintf(stderr,"Sync failed\n");
    return 3;
  }
  getchar();
  if (TextToSpeechShutdown(dtkHandle) != 0)
    fprintf(stderr,"TextToSpeechShutdown failed.\n");
  fprintf(stderr,"All done\n");
}

 Hi all,
 
 I've downloaded and tried to use the

 It hangs

 I'm still looking into it but there isn't anything
