[Octave-bug-tracker] [bug #55273] mkfifo returns "Function not implemented" error

[Andrew Janke]

Follow-up Comment #13, bug #55273 (project octave):

@Mike

Adding CPPFLAGS=-DHAVE_MKFIFO fixes it for me too.

And I can confirm that on macOS, for me, the gnulib trailing-slash-bug fix is
being used. I put debugging statements into the libgnu mkfifo.c:


mkfifo (char const *name _GL_UNUSED, mode_t mode _GL_UNUSED)
{
  printf("gnulib mkfifo() called\n");
[...]
rpl_mkfifo (char const *name, mode_t mode)
{
  printf("gnulib rpl_mkfifo() called\n");


and the rpl_mkfifo() is showing up in the `make` output:


  GEN      doc/interpreter/splinefit4.eps
gnulib rpl_mkfifo() called
gnulib rpl_mkfifo() called


I was also able to get it to build by sticking an AC_DEFINE in configure.ac
before the gl_INIT call:


dnl Fix for mkfifo macro bug
AC_DEFINE([HAVE_MKFIFO], [1], [Whether this system has mkfifo.])

gl_INIT


But I don't know how that will behave on systems that don't have mkfifo.
