20 | My interpretation of the GNU General Public License is that no Perl |
21 | script falls under the terms of the License unless you explicitly put |
22 | said script under the terms of the License yourself. Furthermore, any |
23 | object code linked with uperl.o does not automatically fall under the |
24 | terms of the License, provided such object code only adds definitions |
25 | of subroutines and variables, and does not otherwise impair the |
26 | resulting interpreter from executing any standard Perl script. I |
27 | consider linking in C subroutines in this manner to be the moral |
28 | equivalent of defining subroutines in the Perl language itself. You |
29 | may sell such an object file as proprietary provided that you provide |
30 | or offer to provide the Perl source, as specified by the GNU General |
31 | Public License. (This is merely an alternate way of specifying input |
32 | to the program.) You may also sell a binary produced by the dumping of |
33 | a running Perl script that belongs to you, provided that you provide or |
34 | offer to provide the Perl source as specified by the License. (The |
35 | fact that a Perl interpreter and your code are in the same binary file |
36 | is, in this case, a form of mere aggregation.) This is my interpretation |
37 | of the License. If you still have concerns or difficulties understanding |
38 | my intent, feel free to contact me. |

41 | |
42 | Perl is a language that combines some of the features of C, sed, awk and shell. |
43 | See the manual page for more hype. |
44 | |
45 | Perl will probably not run on machines with a small address space. |
46 | |
47 | Please read all the directions below before you proceed any further, and |
a687059c |
48 | then follow them carefully. |
8d063cd8 |
49 | |
50 | After you have unpacked your kit, you should have all the files listed |
51 | in MANIFEST. |
52 | |
53 | Installation |
54 | |
55 | 1) Run Configure. This will figure out various things about your system. |
56 | Some things Configure will figure out for itself, other things it will |
57 | ask you about. It will then proceed to make config.h, config.sh, and |
fe14fcc3 |
58 | Makefile. If you're a hotshot, run Configure -d to take all the |
59 | defaults and then edit config.sh to patch up any flaws. |
8d063cd8 |
60 | |
61 | You might possibly have to trim # comments from the front of Configure |
62 | if your sh doesn't handle them, but all other # comments will be taken |
63 | care of. |
64 | |
65 | (If you don't have sh, you'll have to copy the sample file config.H to |
66 | config.h and edit the config.h to reflect your system's peculiarities.) |
67 | |
68 | 2) Glance through config.h to make sure system dependencies are correct. |
69 | Most of them should have been taken care of by running the Configure script. |
70 | |
71 | If you have any additional changes to make to the C definitions, they |
1c3d792e |
72 | can be done in cflags.SH. For instance, to turn off the optimizer |
73 | on eval.c, find the line in the switch structure for eval.c and |
74 | put the command $optimize='-g' before the ;;. You will probably |
75 | want to change the entry for teval.c too. To change the C flags |
76 | for all the files, edit config.sh and change either $ccflags or $optimize. |
8d063cd8 |
77 | |
78 | 3) make depend |
79 | |
80 | This will look for all the includes and modify Makefile accordingly. |
81 | Configure will offer to do this for you. |
82 | |
83 | 4) make |
84 | |
85 | This will attempt to make perl in the current directory. |
86 | |
d8f2e4cc |
87 | If you can't compile successfully, try adding a -DCRIPPLED_CC flag. |
88 | (Just because you get no errors doesn't mean it compiled right!) |
89 | This simplifies some complicated expressions for compilers that |
90 | get indigestion easily. If that has no effect, try turning off |
91 | optimization. If you have missing routines, you probably need to |
92 | add some library or other, or you need to undefine some feature that |
93 | Configure thought was there but is defective or incomplete. |
94 | |
95 | Some compilers will not compile or optimize the larger files without |
96 | some extra switches to use larger jump offsets or allocate larger |
1c3d792e |
97 | internal tables. You can customize the switches for each file in |
98 | cflags.SH. It's okay to insert rules for specific files into |
b6ccd89c |
99 | Makefile.SH, since a default rule only takes effect in the |
d8f2e4cc |
100 | absence of a specific rule. |
101 | |
1c3d792e |
102 | Most of the following hints are now done automatically by Configure. |
103 | |
d8f2e4cc |
104 | The 3b2 needs to turn off -O. |
fe14fcc3 |
105 | Compilers with limited switch tables may have to define -DSMALLSWITCHES |
e5d73d77 |
106 | Domain/OS 10.3 (at least) native C 6.7 may need -opt 2 for eval.c |
d8f2e4cc |
107 | AIX/RT may need a -a switch and -DCRIPPLED_CC. |
fe14fcc3 |
108 | AIX RS/6000 needs to use system malloc and avoid -O on eval.c and toke.c. |
109 | AIX RS/6000 needs -D_NO_PROTO. |
21d892ea |
110 | SUNOS 4.0.[12] needs #define fputs(str,fp) fprintf(fp,"%s",str) in perl.h |
e5d73d77 |
111 | SUNOS 3.[45] should use the system malloc. |
fe14fcc3 |
112 | SGI machines may need -Ddouble="long float" and -O1. |
113 | Vax-based systems may need to hand assemble teval.s with a -J switch. |
449aadca |
114 | Ultrix on MIPS machines may need -DLANGUAGE_C. |
1c3d792e |
115 | Ultrix 4.0 on MIPS machines may need -Olimit 2900 or so. |
5303340c |
116 | Ultrix 3.[01] on MIPS needs to undefine WAITPID--the system call is busted. |
117 | MIPS machines may need to undef d_volatile. |
fe14fcc3 |
118 | MIPS machines may need to turn off -O on cmd.c, perl.c and tperl.c. |
5303340c |
119 | Some MIPS machines may need to undefine CASTNEGFLOAT. |
5303340c |
120 | Xenix 386 needs -Sm11000 for yacc, and may need -UM_I86. |
fe14fcc3 |
121 | SCO Xenix may need -m25000 for yacc. See also README.xenix. |
d8f2e4cc |
122 | Genix needs to use libc rather than libc_s, or #undef VARARGS. |
449aadca |
123 | NCR Tower 32 (OS 2.01.01) may need -W2,-Sl,2000 and #undef MKDIR. |
7e1cf235 |
124 | A/UX may appears to work with -O -B/usr/lib/big/ optimizer flags. |
125 | A/UX needs -lposix to find rewinddir. |
79220ce3 |
126 | A/UX may need -ZP -DPOSIX, and -g if big cc is used. |
127 | FPS machines may need -J and -DBADSWITCH. |
5303340c |
128 | UTS may need one or more of -DCRIPPLED_CC, -K or -g, and undef LSTAT. |
fe14fcc3 |
129 | dynix may need to undefine CASTNEGFLOAT (d_castneg='undef' in config.sh). |
4e8eb4f0 |
130 | Dnix (not dynix) may need to remove -O. |
7e1cf235 |
131 | IRIX 3.3 may need to undefine VFORK. |
fe14fcc3 |
132 | HP/UX may need to pull cerror.o and syscall.o out of libc.a and link |
133 | them in explicitly. |
79220ce3 |
134 | If you get syntax errors on '(', try -DCRIPPLED_CC or -DBADSWITCH or both. |
449aadca |
135 | Machines with half-implemented dbm routines will need to #undef ODBM & NDBM. |
fe14fcc3 |
136 | If you have GDBM available and want it instead of NDBM, say -DHAS_GDBM. |
449aadca |
137 | C's that don't try to restore registers on longjmp() may need -DJMPCLOBBER. |
138 | (Try this if you get random glitches.) |
d8f2e4cc |
139 | |
8d063cd8 |
140 | 5) make test |
141 | |
142 | This will run the regression tests on the perl you just made. |
143 | If it doesn't say "All tests successful" then something went wrong. |
378cc40b |
144 | See the README in the t subdirectory. Note that you can't run it |
03a14243 |
145 | in background if this disables opening of /dev/tty. If "make test" |
146 | bombs out, just cd to the t directory and run TEST by hand to see if |
1c3d792e |
147 | it makes any difference. If individual tests bomb, you can run |
148 | them by hand, e.g., ./perl op/groups.t |
8d063cd8 |
149 | |
150 | 6) make install |
151 | |
a687059c |
152 | This will put perl into a public directory (such as /usr/local/bin). |
8d063cd8 |
153 | It will also try to put the man pages in a reasonable place. It will not |
154 | nroff the man page, however. You may need to be root to do this. If |
155 | you are not root, you must own the directories in question and you should |
156 | ignore any messages about chown not working. |
157 | |
158 | 7) Read the manual entry before running perl. |
159 | |
a687059c |
160 | 8) IMPORTANT! Help save the world! Communicate any problems and suggested |
fe14fcc3 |
161 | patches to me, lwall@netlabs.com (Larry Wall), so we can |
8d063cd8 |
162 | keep the world in sync. If you have a problem, there's someone else |
163 | out there who either has had or will have the same problem. |
164 | |
165 | If possible, send in patches such that the patch program will apply them. |
166 | Context diffs are the best, then normal diffs. Don't send ed scripts-- |
167 | I've probably changed my copy since the version you have. |
168 | |
d8f2e4cc |
169 | Watch for perl patches in comp.lang.perl. Patches will generally be |
8d063cd8 |
170 | in a form usable by the patch program. If you are just now bringing up |
171 | perl and aren't sure how many patches there are, write to me and I'll |
172 | send any you don't have. Your current patch level is shown in patchlevel.h. |
173 | |
a687059c |
174 | |
175 | Just a personal note: I want you to know that I create nice things like this |
176 | because it pleases the Author of my story. If this bothers you, then your |
177 | notion of Authorship needs some revision. But you can use perl anyway. :-) |
178 | |
179 | The author. |
