I tried to compile mpd for Windows using Cygwin. After adding some
workarounds (add fake_getaddrinfo.h, check
http://musicpd.org/mantis/view.php?id=1566) I was able to compile mpd.
But when I tried to start it, mpd failed:


$ ./mpd.exe --stdout --verbose
binding to any address
flushing warning messages
done flushing warning messages
current locale is "C"
setting filesystem charset to ISO-8859-1
setFsCharset: fs charset is: ISO-8859-1
reading DB
opening pid file
  1 [main] mpd 1736 C:\cygwin\home\mpx\mpd-test\mpd.exe:
    *** fatal error - MapViewOfFileEx (0x19030000),
    Win3 2 error 6.  Terminating.
  68 [main] mpd 676 fork: child 1736 - died
    waiting for dll loading, errno 11 problems fork'ing for daemon! 

cygserver is running and i did a "$ export CYGWIN=server "

I traced down the error in the file player.c, source:

static int playerInit(void)
{
...
LOG(" debug playerInit: 10\n");
    pid = player_pid;
    if (pid > 0) {
        kill(pid, SIGCONT);
        pc->wait = 0;
        return 0;
    }

LOG(" debug playerInit: 20\n");
    player_pid = fork();    <<<<<<<<<<< CRASH
LOG(" debug playerInit: 30  (pid: %i/%i)\n", pid, player_pid);    
    blockSignals();
LOG(" debug playerInit: 31 \n");        
    if (player_pid==0)


any hints?

regards
