34# You may have dynamic loading problems if the environment variable
35# LDOPTS='-a archive'. Under >= 10.x, you can instead LDOPTS='-a
36# archive_shared' to prefer archive libraries without requiring them.
37# Regardless of HPUX release, in the "libs" variable or the ext.libs
38# file, you can always give explicit path names to archive libraries
39# that may not exist on the target machine. E.g., /usr/lib/libndbm.a
40# instead of -lndbm. See also note below on ndbm.
41#
42# ALSO, bear in mind that gdbm and Berkely DB contain incompatible
43# replacements for ndbm (and dbm) routines. If you want concurrent
44# access to ndbm files, you need to make sure libndbm is linked in
45# *before* gdbm and Berkely DB. Lastly, remember to check the
46# "ext.libs" file which is *probably* messing up the order. Often,
47# you can replace ext.libs with an empty file to fix the problem.
