#! /bin/sh # hints/hpux.sh # Perl Configure hints file for Hewlett-Packard's HP-UX 9.x and 10.x # (Hopefully, 7.x through 11.x.) # # This file is based on hints/hpux_9.sh, Perl Configure hints file for # Hewlett Packard HP-UX 9.x # # Use Configure -Dcc=gcc to use gcc. # # From: Jeff Okamoto # and # hints/hpux_10.sh, Perl Configure hints file for Hewlett Packard HP-UX 10.x # From: Giles Lean # and # Use #define CPU_* instead of comments for >= 10.x. # Support PA1.2 under 10.x. # Distinguish between PA2.0, PA2.1, etc. # Distinguish between MC68020, MC68030, MC68040 # Don't assume every OS != 10 is < 10, (e.g., 11). # From: Chuck Phillips # This version: August 15, 1997 # Current maintainer: Jeff Okamoto #-------------------------------------------------------------------- # Use Configure -Dcc=gcc to use gcc. # Use Configure -Dprefix=/usr/local to install in /usr/local. # # You may have dynamic loading problems if the environment variable # LDOPTS='-a archive'. Under >= 10.x, you can instead LDOPTS='-a # archive_shared' to prefer archive libraries without requiring them. # Regardless of HPUX release, in the "libs" variable or the ext.libs # file, you can always give explicit path names to archive libraries # that may not exist on the target machine. E.g., /usr/lib/libndbm.a # instead of -lndbm. See also note below on ndbm. # # ALSO, bear in mind that gdbm and Berkely DB contain incompatible # replacements for ndbm (and dbm) routines. If you want concurrent # access to ndbm files, you need to make sure libndbm is linked in # *before* gdbm and Berkely DB. Lastly, remember to check the # "ext.libs" file which is *probably* messing up the order. Often, # you can replace ext.libs with an empty file to fix the problem. # # If you get a message about "too much defining", as may happen # in HPUX < 10, you might have to append a single entry to your # ccflags: '-Wp,-H256000' # NOTE: This is a single entry (-W takes the argument 'p,-H256000'). #-------------------------------------------------------------------- # Turn on the _HPUX_SOURCE flag to get many of the HP add-ons # regardless of compiler. For the HP ANSI C compiler, you may also # want to include +e to enable "long long" and "long double". # # HP compiler flags to include (if at all) *both* as part of ccflags # and cc itself so Configure finds (and builds) everything # consistently: # -Aa -D_HPUX_SOURCE +e # # Lastly, you may want to include the "-z" HP linker flag so that # reading from a NULL pointer causes a SEGV. ccflags="$ccflags -D_HPUX_SOURCE" # Check if you're using the bundled C compiler.
