4# Perl Configure hints file for Hewlett-Packard's HP-UX 9.x and 10.x
5# (Hopefully, 7.x through 11.x.)
6#
7# This file is based on hints/hpux_9.sh, Perl Configure hints file for
8# Hewlett Packard HP-UX 9.x
9#
10# Use Configure -Dcc=gcc to use gcc.
11#
12# From: Jeff Okamoto <okamoto@corp.hp.com>
13# and
14# hints/hpux_10.sh, Perl Configure hints file for Hewlett Packard HP-UX 10.x
15# From: Giles Lean <giles@nemeton.com.au>
16# and
17# Use #define CPU_* instead of comments for >= 10.x.
18# Support PA1.2 under 10.x.
19# Distinguish between PA2.0, PA2.1, etc.
20# Distinguish between MC68020, MC68030, MC68040
21# Don't assume every OS != 10 is < 10, (e.g., 11).

35#--------------------------------------------------------------------
36# Use Configure -Dcc=gcc to use gcc.
37# Use Configure -Dprefix=/usr/local to install in /usr/local.
38#
39# You may have dynamic loading problems if the environment variable
40# LDOPTS='-a archive'.  Under >= 10.x, you can instead LDOPTS='-a
41# archive_shared' to prefer archive libraries without requiring them.
42# Regardless of HPUX release, in the "libs" variable or the ext.libs
43# file, you can always give explicit path names to archive libraries
44# that may not exist on the target machine.  E.g., /usr/lib/libndbm.a
45# instead of -lndbm.  See also note below on ndbm.
46#
47# ALSO, bear in mind that gdbm and Berkely DB contain incompatible
48# replacements for ndbm (and dbm) routines.  If you want concurrent
49# access to ndbm files, you need to make sure libndbm is linked in
50# *before* gdbm and Berkely DB.  Lastly, remember to check the
51# "ext.libs" file which is *probably* messing up the order.  Often,
52# you can replace ext.libs with an empty file to fix the problem.
53#
54# If you get a message about "too much defining", as may happen
55# in HPUX < 10, you might have to append a single entry to your
56# ccflags: '-Wp,-H256000'
57# NOTE: This is a single entry (-W takes the argument 'p,-H256000').
58#--------------------------------------------------------------------

60# Turn on the _HPUX_SOURCE flag to get many of the HP add-ons
61# regardless of compiler.  For the HP ANSI C compiler, you may also
62# want to include +e to enable "long long" and "long double".
63#
64# HP compiler flags to include (if at all) *both* as part of ccflags
65# and cc itself so Configure finds (and builds) everything
66# consistently:
67#	-Aa -D_HPUX_SOURCE +e
68#
69# Lastly, you may want to include the "-z" HP linker flag so that
70# reading from a NULL pointer causes a SEGV.
