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 | |
25 | # (e.g., libgdbm.so). | |
26 | # | |
27 | # If you want to link against such a library, you must install the development | |
28 | # version of the package. | |
29 | # | |
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. | |
35 | # | |
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. | |

47 | # Addendum for 5.005_57 and beyond: | |
48 | # | |
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. | |
53 | # | |
54 | # Here is what we used to do: | |
55 | # Allow a command line override, e.g. Configure -Dprefix=/foo/bar | |
56 | # case "$prefix" in | |
57 | # '') prefix='/usr' ;; | |
58 | # esac | |
59 | # | |
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 5.006_50 and beyond. | |
