# 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.

#     These warnings are harmless and can be safely ignored.
