I've been using Cygwin 1.7 alongside Cygwin 1.5 quite happily for the last few hours, however all-of-a-sudden when I try and run mintty (from cygstart or from a cmd.exe shell) I get a new window with this error message:
Failed to create child process: No such file or directory Hitting "enter" makes the window close. I messed around with this for a while until I discovered something very obvious - I already had a mintty running. It appears that in Cygwin 1.7 I cannot run more than one instance of mintty at a time. In 1.5, I have happily run many, many instances simultaneously. However I can run bash.exe without a problem, and in doing so I tried an strace: ... 115 166255 [main] mintty 4336 tty_list::allocate: tty1 allocated 91 166346 [main] mintty 4336 fhandler_pipe::create_selectable: CreateNamedPipe: name \\.\pipe\cygwin-tty1-from-master, size 131072 144 166490 [main] mintty 4336 fhandler_pipe::create_selectable: pipe read handle 0x6C4 82 166572 [main] mintty 4336 fhandler_pipe::create_selectable: CreateFile: name \\.\pipe\cygwin-tty1-from-master 103 166675 [main] mintty 4336 fhandler_pipe::create_selectable: pipe write handle 0x6CC 85 166760 [main] mintty 4336 fhandler_pipe::create_selectable: CreateNamedPipe: name \\.\pipe\cygwin-tty1-to-master, size 131072 242 167002 [main] mintty 4336 fhandler_pipe::create_selectable: pipe busy 77 167079 [main] mintty 4336 seterrno_from_win_error: /netrel/src/cygwin-1.7.0-61/winsup/cygwin/fhandler_tty.cc:1439 windows error 231 79 167158 [main] mintty 4336 geterrno_from_win_error: windows error 231 == errno 16 73 167231 [main] mintty 4336 __set_errno: void seterrno_from_win_error(const char*, int, DWORD):319 val 16 84 167315 [main] mintty 4336 fhandler_pty_master::setup: tty1629019509 open failed - failed to create (null) 89 167404 [main] mintty 4336 open: -1 = open (/dev/ptmx, 0x8002) 83 167487 [main] mintty 4336 __set_errno: int openpty(int*, int*, char*, termios*, winsize*):128 val 2 Looks like there's a "busy pipe" that is causing mintty to abort?
