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. |

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 |
58 | Makefile. |
59 | |
60 | You might possibly have to trim # comments from the front of Configure |
61 | if your sh doesn't handle them, but all other # comments will be taken |
62 | care of. |
63 | |
64 | (If you don't have sh, you'll have to copy the sample file config.H to |
65 | config.h and edit the config.h to reflect your system's peculiarities.) |
66 | |
67 | 2) Glance through config.h to make sure system dependencies are correct. |
68 | Most of them should have been taken care of by running the Configure script. |
69 | |
70 | If you have any additional changes to make to the C definitions, they |
71 | can be done in the Makefile, or in config.h. Bear in mind that they will |
72 | get undone next time you run Configure. |
73 | |
74 | 3) make depend |
75 | |
76 | This will look for all the includes and modify Makefile accordingly. |
77 | Configure will offer to do this for you. |
78 | |
79 | 4) make |
80 | |
81 | This will attempt to make perl in the current directory. |
82 | |
d8f2e4cc |
83 | If you can't compile successfully, try adding a -DCRIPPLED_CC flag. |
84 | (Just because you get no errors doesn't mean it compiled right!) |
85 | This simplifies some complicated expressions for compilers that |
86 | get indigestion easily. If that has no effect, try turning off |
87 | optimization. If you have missing routines, you probably need to |
88 | add some library or other, or you need to undefine some feature that |
89 | Configure thought was there but is defective or incomplete. |
90 | |
91 | Some compilers will not compile or optimize the larger files without |
92 | some extra switches to use larger jump offsets or allocate larger |
93 | internal tables. It's okay to insert rules for specific files into |
b6ccd89c |
94 | Makefile.SH, since a default rule only takes effect in the |
d8f2e4cc |
95 | absence of a specific rule. |
96 | |
97 | The 3b2 needs to turn off -O. |
e5d73d77 |
98 | Domain/OS 10.3 (at least) native C 6.7 may need -opt 2 for eval.c |
d8f2e4cc |
99 | AIX/RT may need a -a switch and -DCRIPPLED_CC. |
21d892ea |
100 | SUNOS 4.0.[12] needs #define fputs(str,fp) fprintf(fp,"%s",str) in perl.h |
e5d73d77 |
101 | SUNOS 3.[45] should use the system malloc. |
d8f2e4cc |
102 | SGI machines may need -Ddouble="long float". |
103 | Ultrix (2.3) may need to hand assemble teval.s with a -J switch. |
449aadca |
104 | Ultrix on MIPS machines may need -DLANGUAGE_C. |
5303340c |
105 | Ultrix 3.[01] on MIPS needs to undefine WAITPID--the system call is busted. |
106 | MIPS machines may need to undef d_volatile. |
79220ce3 |
107 | MIPS machines may need to turn off -O on perly.c and tperly.c. |
5303340c |
108 | Some MIPS machines may need to undefine CASTNEGFLOAT. |
d8f2e4cc |
109 | SCO Xenix may need -m25000 for yacc. |
5303340c |
110 | Xenix 386 needs -Sm11000 for yacc, and may need -UM_I86. |
d8f2e4cc |
111 | Genix needs to use libc rather than libc_s, or #undef VARARGS. |
449aadca |
112 | NCR Tower 32 (OS 2.01.01) may need -W2,-Sl,2000 and #undef MKDIR. |
79220ce3 |
113 | A/UX may need -ZP -DPOSIX, and -g if big cc is used. |
114 | FPS machines may need -J and -DBADSWITCH. |
5303340c |
115 | UTS may need one or more of -DCRIPPLED_CC, -K or -g, and undef LSTAT. |
79220ce3 |
116 | If you get syntax errors on '(', try -DCRIPPLED_CC or -DBADSWITCH or both. |
449aadca |
117 | Machines with half-implemented dbm routines will need to #undef ODBM & NDBM. |
118 | C's that don't try to restore registers on longjmp() may need -DJMPCLOBBER. |
119 | (Try this if you get random glitches.) |

121 | 5) make test |
122 | |
123 | This will run the regression tests on the perl you just made. |
124 | If it doesn't say "All tests successful" then something went wrong. |
378cc40b |
125 | See the README in the t subdirectory. Note that you can't run it |
03a14243 |
126 | in background if this disables opening of /dev/tty. If "make test" |
127 | bombs out, just cd to the t directory and run TEST by hand to see if |
128 | it makes any difference. |
8d063cd8 |
129 | |
130 | 6) make install |
131 | |
a687059c |
132 | This will put perl into a public directory (such as /usr/local/bin). |
8d063cd8 |
133 | It will also try to put the man pages in a reasonable place. It will not |
134 | nroff the man page, however. You may need to be root to do this. If |
135 | you are not root, you must own the directories in question and you should |
136 | ignore any messages about chown not working. |
137 | |
138 | 7) Read the manual entry before running perl. |
139 | |
a687059c |
140 | 8) IMPORTANT! Help save the world! Communicate any problems and suggested |
8d063cd8 |
141 | patches to me, lwall@jpl-devvax.jpl.nasa.gov (Larry Wall), so we can |
142 | keep the world in sync. If you have a problem, there's someone else |
143 | out there who either has had or will have the same problem. |
144 | |
145 | If possible, send in patches such that the patch program will apply them. |
146 | Context diffs are the best, then normal diffs. Don't send ed scripts-- |
147 | I've probably changed my copy since the version you have. |
148 | |
d8f2e4cc |
149 | Watch for perl patches in comp.lang.perl. Patches will generally be |
8d063cd8 |
150 | in a form usable by the patch program. If you are just now bringing up |
151 | perl and aren't sure how many patches there are, write to me and I'll |
152 | send any you don't have. Your current patch level is shown in patchlevel.h. |
153 | |

154 | |
155 | Just a personal note: I want you to know that I create nice things like this |
156 | because it pleases the Author of my story. If this bothers you, then your |
157 | notion of Authorship needs some revision. But you can use perl anyway. :-) |
