run_erl/to_erl on FreeBSD
Wed Mar 30 09:24:39 CEST 2005
Yes, that is correct.
I changed mknod() to mkfifo() because mknod() on Mac OS X
requires the user to be root, even when creating a FIFO.
mkfifo() is the recommended way to create a FIFO, and is
supposed to work on all modern Unix platforms, so I found no
reason to continue to use mknod() on platforms where it works.
Our test case for run_erl/to_erl runs succesfully on FreeBSD.
We use the following version of FreeBSD:
FreeBSD 5.0-RELEASE #0: Thu Jan 16 22:16:53 GMT 2003
Which version of FreeBSD do you use? Does run_erl run using
R10B-2 or R10B-3?
