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

47 | # in HPUX < 10, you might have to append a single entry to your |
48 | # ccflags: '-Wp,-H256000' |
49 | # NOTE: This is a single entry (-W takes the argument 'p,-H256000'). |
