# Run this script from the OpenSSL root directory:
# sh shlib/hpux10-cc.sh
#
# HP-UX (10.20) shared library installation:
# Compile and install OpenSSL with best possible optimization:
# - shared libraries are compiled and installed with +O4 optimization
# - executable(s) are compiled and installed with +O4 optimization
# - static libraries are compiled and installed with +O3 optimization,
# to avoid the time consuming +O4 link-time optimization when using
# these libraries. (The shared libs are already optimized during build
# at +O4.)
#
# This script must be run with appropriate privileges to install into
# /usr/local/ssl. HP-UX prevents used executables and shared libraries
# from being deleted or overwritten. Stop all processes using already
# installed items of OpenSSL.
#
# WARNING: At high optimization levels, HP's ANSI-C compiler can chew up
# large amounts of memory and CPU time. Make sure to have at least
# 128MB of RAM available and that your kernel is configured to allow
# at least 128MB data size (maxdsiz parameter which can be obtained
# by multiplying 'echo maxdsiz/D | adb -k /stand/vmunix /dev/kmem'
# by 'getconf PAGE_SIZE').
# The installation process can take several hours, even on fast
# machines. +O4 optimization of the libcrypto.sl shared library may
# take 1 hour on a C200 (200MHz PA8200 CPU), +O3 compilation of
# fcrypt_b.c can take 20 minutes on this machine. Stay patient.
#
# SITEFLAGS: site specific flags. I do use +DAportable, since I have to
# support older PA1.1-type CPUs. Your mileage may vary.
# +w1 enables enhanced warnings, useful when working with snaphots.
#
SITEFLAGS="+DAportable +w1"
#
# Set the default additions to build with HP-UX.
# -D_REENTRANT must/should be defined on HP-UX manually, since we do call
# Configure directly.
# +Oall increases the optimization done.
