I've got a strange problem compiling stunnel-3.15
configure calls the following checks:
AC_CHECK_FILE("/dev/ptmx", AC_DEFINE_UNQUOTED(HAVE_DEV_PTMX))
AC_CHECK_FILE("/dev/ptc", AC_DEFINE_UNQUOTED(HAVE_DEV_PTS_AND_PTC))
The first check succeeds(!) and the second fails.
ls -al /dev gives:
total 0
srwxrwxrwx 1 Administ None 15 Jun 19 2000 log
crw-rw-rw- 1 Everyone Everyone 19, 0 Jul 20 2001 null
To fix this all I have to do is delete the HAVE_DEV_PTMX define in Makefile
but I would like to know what is going on.
Thanks for any ideas
John Jarvie

That's because cygwin has a virtual /dev/ptmx and no /dev/ptc. You are
getting the correct results.

This is irrelevant :-/. Sorry.

Yes, the check breaks on cygwin. May be, replacing it with AC_TRY_RUN a
pogram that contains
open("/dev/ptmx", O_RDWR)
would be a better idea (and it will have the same implication on cross
compiling).

Somebody has created them but cygwin does not use these files.

Robert, Corinna , Andrej
Thanks for the replies which explain what's going on.
If I leave the PTMX define in the compile fails on
if (ioctl(*ttyfd, I_PUSH, "ptem") < 0)
sockerror("ioctl I_PUSH ptem");
if (ioctl(*ttyfd, I_PUSH, "ldterm") < 0)
sockerror("ioctl I_PUSH ldterm");
if (ioctl(*ttyfd, I_PUSH, "ttcompat") < 0)
sockerror("ioctl I_PUSH ttcompat");
I_PUSH is not defined, on Linux this is in
/usr/include/bits/stropts.h
Thanks for the help

What has it to do with Linux? You need enclose it either in #ifndef
__CYGWIN__ or #ifdef I_PUSH.

#endif
I_PUSH has no meaning for Cygwin.

Thanks for the help, I'll create a cygwin diff and submit it to the stunnel
project.
Best regards
