# Hints for the PowerUX operating system running on Concurrent (formerly
# Harris) NightHawk machines.  Written by Tom.Horsley@mail.ccur.com
#
# Note: The OS is fated to change names again to PowerMAX OS, but this
# PowerUX file should still work (I wish marketing would make up their mind
# about the name :-).
#
# This config uses dynamic linking and the Concurrent C compiler.  It has
# been tested on Power PC based 6000 series machines running PowerUX.

# Internally at Concurrent, we use a source management tool which winds up
# giving us read-only copies of source trees that are mostly symbolic links.
# That upsets the perl build process when it tries to edit opcode.h and
# embed.h or touch perly.c or perly.h, so turn those files into "real" files
# when Configure runs. (If you already have "real" source files, this won't
# do anything).

# We DO NOT want -lmalloc or -lPW, we DO need -lgen to follow -lnsl, so

# Need to use Concurrent cc for most of these options to be meaningful (if you
# want to get this to work with gcc, you're on your own :-). Passing

# loaded on demand (and will try to reference those symbols).

# Configure sometime finds what it believes to be ndbm header files on the

# PowerMAX OS has support for a few different kinds of filesystems. The
# newer "xfs" filesystem does *not* report a reasonable value in the
# 'nlinks' field of stat() info for directories (in fact, it is always 1).
# Since xfs is the only filesystem which supports partitions bigger than
# 2gig and you can't hardly buy a disk that small anymore, xfs is coming in
# to greater and greater use, so we pretty much have no choice but to
# abandon all hope that number of links will mean anything.
