1 [This is an unsupported, pre-release version of Perl 5.0. It is expected
2 to work only on a Sparc architecture machine. No Configure support is
3 provided. In fact, if you succeed in configuring and making a new
4 makefile, you'll probably overwrite the only makefile that works. Note
5 that a Sparc executable comes with the kit, so you may not need to
6 compile at all. There is no list of new features yet, but if you look
7 at t/op/ref.t you'll see some of them in use. perl -Dxst is also fun.]

35 For those of you that choose to use the GNU General Public License,
36 my interpretation of the GNU General Public License is that no Perl
37 script falls under the terms of the GPL unless you explicitly put
38 said script under the terms of the GPL yourself. Furthermore, any
39 object code linked with uperl.o does not automatically fall under the
40 terms of the GPL, provided such object code only adds definitions
41 of subroutines and variables, and does not otherwise impair the
42 resulting interpreter from executing any standard Perl script. I
43 consider linking in C subroutines in this manner to be the moral
44 equivalent of defining subroutines in the Perl language itself. You
45 may sell such an object file as proprietary provided that you provide
46 or offer to provide the Perl source, as specified by the GNU General
47 Public License. (This is merely an alternate way of specifying input
48 to the program.) You may also sell a binary produced by the dumping of
49 a running Perl script that belongs to you, provided that you provide or
50 offer to provide the Perl source as specified by the GPL. (The
51 fact that a Perl interpreter and your code are in the same binary file
52 is, in this case, a form of mere aggregation.) This is my interpretation
53 of the GPL. If you still have concerns or difficulties understanding
54 my intent, feel free to contact me. Of course, the Artistic License
55 spells all this out for your protection, so you may prefer to use that.

59 Perl is a language that combines some of the features of C, sed, awk
60 and shell. See the manual page for more hype. There's also a Nutshell
61 Handbook published by O'Reilly & Assoc. Their U.S. number is
62 1-800-998-9938 and their international number is 1-707-829-0515.
63 E-mail to nuts@ora.com.
65 Please read all the directions below before you proceed any further, and
66 then follow them carefully.
68 After you have unpacked your kit, you should have all the files listed
73 1) Run Configure. This will figure out various things about your system.
74 Some things Configure will figure out for itself, other things it will
75 ask you about. It will then proceed to make config.h, config.sh, and
76 Makefile. If you're a hotshot, run Configure -d to take all the
77 defaults and then edit config.sh to patch up any flaws.
79 You might possibly have to trim # comments from the front of Configure
80 if your sh doesn't handle them, but all other # comments will be taken
83 (If you don't have sh, you'll have to copy the sample file config.H to
84 config.h and edit the config.h to reflect your system's peculiarities.)
86 2) Glance through config.h to make sure system dependencies are correct.
87 Most of them should have been taken care of by running the Configure script.
89 If you have any additional changes to make to the C definitions, they
90 can be done in cflags.SH. For instance, to turn off the optimizer
91 on eval.c, find the line in the switch structure for eval.c and
92 put the command $optimize='-g' before the ;;. You will probably
93 want to change the entry for teval.c too. To change the C flags
94 for all the files, edit config.sh and change either $ccflags or $optimize.
98 This will look for all the includes and modify Makefile accordingly.
99 Configure will offer to do this for you.
103 This will attempt to make perl in the current directory.
105 If you can't compile successfully, try adding a -DCRIPPLED_CC flag.
106 (Just because you get no errors doesn't mean it compiled right!)
107 This simplifies some complicated expressions for compilers that
108 get indigestion easily. If that has no effect, try turning off
109 optimization. If you have missing routines, you probably need to
110 add some library or other, or you need to undefine some feature that
111 Configure thought was there but is defective or incomplete.
113 Some compilers will not compile or optimize the larger files without
114 some extra switches to use larger jump offsets or allocate larger
115 internal tables. You can customize the switches for each file in
116 cflags.SH. It's okay to insert rules for specific files into
117 Makefile.SH, since a default rule only takes effect in the
118 absence of a specific rule.
120 Most of the following hints are now done automatically by Configure.
122 The 3b2 needs to turn off -O.
123 Compilers with limited switch tables may have to define -DSMALLSWITCHES
124 Domain/OS 10.3 (at least) native C 6.7 may need -opt 2 for eval.c
125 AIX/RT may need a -a switch and -DCRIPPLED_CC.
126 AIX RS/6000 needs to use system malloc and avoid -O on eval.c and toke.c.
127 AIX RS/6000 needs -D_NO_PROTO.
128 SUNOS 4.0.[12] needs -DFPUTS_BOTCH.
129 SUNOS 3.[45] should use the system malloc.
130 SGI machines may need -Ddouble="long float" and -O1.
131 Vax-based systems may need to hand assemble teval.s with a -J switch.
132 Ultrix on MIPS machines may need -DLANGUAGE_C.
133 Ultrix 4.0 on MIPS machines may need -Olimit 2900 or so.
134 Ultrix 3.[01] on MIPS needs to undefine WAITPID--the system call is busted.
135 MIPS machines need /bin before /bsd43/bin in PATH.
136 MIPS machines may need to undef d_volatile.
137 MIPS machines may need to turn off -O on cmd.c, perl.c and tperl.c.
138 Some MIPS machines may need to undefine CASTNEGFLOAT.
139 Xenix 386 needs -Sm11000 for yacc, and may need -UM_I86.
140 SCO Xenix may need -m25000 for yacc. See also README.xenix.
141 Genix needs to use libc rather than libc_s, or #undef VARARGS.
142 NCR Tower 32 (OS 2.01.01) may need -W2,-Sl,2000 and #undef MKDIR.
143 A/UX may appears to work with -O -B/usr/lib/big/ optimizer flags.
144 A/UX needs -lposix to find rewinddir.
145 A/UX may need -ZP -DPOSIX, and -g if big cc is used.
146 FPS machines may need -J and -DBADSWITCH.
147 UTS may need one or more of -DCRIPPLED_CC, -K or -g, and undef LSTAT.
148 dynix may need to undefine CASTNEGFLOAT (d_castneg='undef' in config.sh).
149 Dnix (not dynix) may need to remove -O.
150 IRIX 3.3 may need to undefine VFORK.
151 HP/UX may need to pull cerror.o and syscall.o out of libc.a and link
153 If you get syntax errors on '(', try -DCRIPPLED_CC or -DBADSWITCH or both.
154 Machines with half-implemented dbm routines will need to #undef ODBM & NDBM.
155 If you have GDBM available and want it instead of NDBM, say -DHAS_GDBM.
156 C's that don't try to restore registers on longjmp() may need -DJMPCLOBBER.
157 (Try this if you get random glitches.)
158 If you get duplicates upon linking for malloc et al, say -DHIDEMYMALLOC.
159 Turn on support for 64-bit integers (long longs) with -DQUAD.
163 This will run the regression tests on the perl you just made.
164 If it doesn't say "All tests successful" then something went wrong.
165 See the README in the t subdirectory. Note that you can't run it
166 in background if this disables opening of /dev/tty. If "make test"
167 bombs out, just cd to the t directory and run TEST by hand to see if
168 it makes any difference. If individual tests bomb, you can run
169 them by hand, e.g., ./perl op/groups.t
173 This will put perl into a public directory (such as /usr/local/bin).
174 It will also try to put the man pages in a reasonable place. It will not
175 nroff the man page, however. You may need to be root to do this. If
176 you are not root, you must own the directories in question and you should
177 ignore any messages about chown not working.
179 7) Read the manual entry before running perl.
181 8) IMPORTANT! Help save the world! Communicate any problems and suggested
182 patches to me, lwall@netlabs.com (Larry Wall), so we can
183 keep the world in sync. If you have a problem, there's someone else
184 out there who either has had or will have the same problem.
186 If possible, send in patches such that the patch program will apply them.
187 Context diffs are the best, then normal diffs. Don't send ed scripts--
188 I've probably changed my copy since the version you have. It's also
189 helpful if you send the output of "uname -a".
191 Watch for perl patches in comp.lang.perl. Patches will generally be
192 in a form usable by the patch program. If you are just now bringing up
193 perl and aren't sure how many patches there are, write to me and I'll
194 send any you don't have. Your current patch level is shown in patchlevel.h.
197 Just a personal note: I want you to know that I create nice things like this
198 because it pleases the Author of my story. If this bothers you, then your
199 notion of Authorship needs some revision. But you can use perl anyway. :-)
