# Hints for the Power MAX OS operating system (formerly PowerUX - hence the
# name) running on Concurrent (formerly Harris) NightHawk machines.  Written
# by Tom.Horsley@ccur.com
#
# This hint uses dynamic linking and the new Concurrent C compiler (based
# on the Edison front end).  This hint file was produced for a build of the
# 5.7.3 development release of perl running on a PowerMAX_OS 5.1SR2 system
# (but it should work on any Power MAX release using the newer "ec" (versus
# "cc") compiler, and hopefully will also work for the upcoming 5.8
# development release of perl).

# First find out where the root of the source tree is located.

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

# DNS name lookup to work, which seems desirable :-).

# want to get this to work with gcc, you're on your own :-). Passing
# -Bexport to the linker when linking perl is important because it leaves
# the interpreter internal symbols visible to the shared libs that will be
# loaded on demand (and will try to reference those symbols). The -usys_nerr
# drags in some stuff from libc that perl proper doesn't reference but
# some dynamically linked extension will need to be in the static part
# of perl (there are probably more of these that might be useful, but
# for the extensions I build, this turned out to be enough). The -uldexp
# makes sure the custom ldexp.o I add to archobjs actually gets pulled
# into perl from libperl.a.  The -unanosleep makes Timer::HiRes happy.

# Sigh... Various versions of Power MAX went out with a broken ldexp runtime
# routine in libc (it is fixed for sure in the upcoming SR4 release, but
# that hasn't made it out the door yet). Since libc is linked dynamically,
# and the perl you build might try to run on one of the broken systems, we
# need to statically link a corrected copy of ldexp.o into perl. What the
# following code does is determine if the ldexp.o on the current system
# works right. If it does, it simply extracts the ldexp.o from the system C
# library and uses that .o file. If the system .o is broken, the btoa
# encoded copy of a correct ldexp.o file included in this hint file is used
# (what a pain...)
