Re: [gpsd-dev] [PATCH 1/2] Moves Linux-only ppscheck program back to contrib/.

[Chris Kuethe]

TIOCMIWAIT doesn't exist on OSX, any of the BSDs or Solaris.  I can't find any reference to it in POSIX.

I can confirm that you broke NetBSD and FreeBSD.

As far as I know, the ioctl it needs is only available on Linux.

ppscheck.c: In function 'main':
ppscheck.c:107:16: error: 'TIOCMIWAIT' undeclared (first use in this function)
  if (ioctl(fd, TIOCMIWAIT, TIOCM_CD|TIOCM_DSR|TIOCM_RI|TIOCM_CTS) != 0) {

It might work to replace that with a short wait - as long as the rest of the
code ignores extra wakeups.

GDB has a 'break' feature; why doesn't it have 'fix' too?
