16 # NDBM support for ELF renabled by <kjahds@kjahds.com>
18 # No version of Linux supports setuid scripts.
21 # Debian and Red Hat, and perhaps other vendors, provide both runtime and
22 # development packages for some libraries. The runtime packages contain shared
23 # libraries with version information in their names (e.g., libgdbm.so.1.7.3);
24 # the development packages supplement this with versionless shared libraries
27 # If you want to link against such a library, you must install the development
28 # version of the package.
30 # These packages use a -dev naming convention in both Debian and Red Hat:
31 # libgdbmg1 (non-development version of GNU libc 2-linked GDBM library)
32 # libgdbmg1-dev (development version of GNU libc 2-linked GDBM library)
33 # So make sure that for any libraries you wish to link Perl with under
34 # Debian or Red Hat you have the -dev packages installed.
36 # Some operating systems (e.g., Solaris 2.6) will link to a versioned shared
37 # library implicitly. For example, on Solaris, `ld foo.o -lgdbm' will find an
38 # appropriate version of libgdbm, if one is available; Linux, however, doesn't
39 # do the implicit mapping.

42 # perl goes into the /usr tree. See the Filesystem Standard
43 # available via anonymous FTP at tsx-11.mit.edu in
44 # /pub/linux/docs/linux-standards/fsstnd.
45 # Allow a command line override, e.g. Configure -Dprefix=/foo/bar
47 # Addendum for 5.005_57 and beyond:
49 # However, most Linux users probably already have a /usr/bin/perl.
50 # We can't know whether the current user is intending to *replace*
51 # that /usr/bin/perl or whether the user is intending to install
52 # a *different* installation.
54 # Here is what we used to do:
55 # Allow a command line override, e.g. Configure -Dprefix=/foo/bar
57 # '') prefix='/usr' ;;
60 # For now, let's assume that most Linux users get their /usr/bin/perl
61 # from some packaging system, so that those compiling from source are
62 # probably the more experimental folks and hence probably aren't
63 # intending to replace /usr/bin/perl (at least just yet).
64 # This change makes linux consistent with most other unix platforms
65 # in having a default of prefix=/usr/local.
66 # These notes can probably safely be removed in 5.005_50 and beyond.

136 You don't have an ELF gcc. I will use dld if possible. If you are
137 using a version of DLD earlier than 3.2.6, or don't have it at all, you
138 should probably upgrade. If you are forced to use 3.2.4, you should
139 uncomment a couple of lines in hints/linux.sh and restart Configure so
140 that shared libraries will be disallowed.

157 # In addition, on some systems there is a problem with perl and NDBM
158 # which causes AnyDBM and NDBM_File to lock up. This is evidenced
159 # in the tests as AnyDBM just freezing. Apparently, this only
160 # happens on a.out systems, so we disable NDBM for all a.out linux
161 # systems. If someone can suggest a more robust test

170 # during the call to dbm_open. Not *in* dbm_open -- but between the call
171 # to and the jump into.
173 # To make a long story short, making sure that the *.a and *.sa pairs of
174 # /usr/lib/lib{m,db,gdbm}.{a,sa}
175 # were perfectly in sync took care of it.

201 Upgrading to a recent version (1.14.4 or later) should fix the problem.
