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