We are running GNU Emacs version 18.53 under SunOS 4.0 on a Sun 3/280 system. I believe that I have correctly built emacs from the distribution on prep. The problem is that emacs hangs indefinitely when it is run from /bin/sh. This would not be much of a problem if not for the fact that things like /etc/vipw invoke emacs in this manner. Is this a known problem with 18.53 or am I just getting screwed by SunOS 4.0? I have not tried building 18.53 on another system yet, but I can arrange to do that if need be. Thanks for your help. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Rajeev Jayavant Quote: "Excuse me. I've lost my marbles." (P.

I just finished fighting with the exact same problem (down to the hardware even). I found that emacs would start fine from the shell (/bin/csh in this case), but locked up when fired off by something like vipw, mail, ingres, etc. Here's a fix that works, but is far from elegant: in emacs.c: ================================================================ # if defined (NMTHACK) { int pgrp; ioctl (fileno (stdin), TIOCGPGRP, &pgrp); if (getpid () != pgrp) { setpgrp (pgrp, pgrp); } else { ioctl (fileno (stdin), TIOCSPGRP, &pgrp); } } # else #ifdef BSD /* interrupt_input has trouble if we aren't in a separate process group. */ setpgrp (getpid (), getpid ()); #endif # endif ================================================================ Note that I also moved the whole thing below the handling for ``-t'', on the off-chance that file descriptors were getting hosed. I haven't checked yet, but I think the second ioctl is redundant. Works for me.... Dieter -- Welcome to the island. You are number six. dieter%nmt@relay.cs.net dieter@jupiter.nmt.edu
