5 | =head1 DESCRIPTION |
6 | |
7 | This section of the FAQ answers questions about where to find |
92c2ed05 |
8 | source and documentation for Perl, support, and |
68dc0745 |
9 | related matters. |
10 | |
b68463f7 |
11 | =head2 What machines support perl? Where do I get it? |
68dc0745 |
12 | |
b68463f7 |
13 | The standard release of perl (the one maintained by the perl |
5e3006a4 |
14 | development team) is distributed only in source code form. You |
c355f4f4 |
15 | can find this at http://www.cpan.org/src/latest.tar.gz , which |
7ed4b849 |
16 | is in a standard Internet format (a gzipped archive in POSIX tar format). |
5e3006a4 |
17 | |
18 | Perl builds and runs on a bewildering number of platforms. Virtually |
b68463f7 |
19 | all known and current Unix derivatives are supported (perl's native |
87275199 |
20 | platform), as are other systems like VMS, DOS, OS/2, Windows, |
c355f4f4 |
21 | QNX, BeOS, OS X, MPE/iX and the Amiga. |
5e3006a4 |
22 | |
23 | Binary distributions for some proprietary platforms, including |
c355f4f4 |
24 | Apple systems, can be found http://www.cpan.org/ports/ directory. |
5e3006a4 |
25 | Because these are not part of the standard distribution, they may |
b68463f7 |
26 | and in fact do differ from the base perl port in a variety of ways. |
5e3006a4 |
27 | You'll have to check their respective release notes to see just |
28 | what the differences are. These differences can be either positive |
29 | (e.g. extensions for the features of the particular platform that |
30 | are not supported in the source release of perl) or negative (e.g. |
31 | might be based upon a less current source release of perl). |
92c2ed05 |
32 | |
b68463f7 |
33 | =head2 How can I get a binary version of perl? |
68dc0745 |
34 | |
65acb1b1 |
35 | If you don't have a C compiler because your vendor for whatever |
36 | reasons did not include one with your system, the best thing to do is |
68dc0745 |
37 | grab a binary version of gcc from the net and use that to compile perl |
38 | with. CPAN only has binaries for systems that are terribly hard to |
39 | get free compilers for, not for Unix systems. |
40 | |
65acb1b1 |
41 | Some URLs that might help you are: |
42 | |
c355f4f4 |
43 | http://www.cpan.org/ports/ |
5c5bc629 |
44 | http://www.perl.com/pub/language/info/software.html |
65acb1b1 |
45 | |
b68463f7 |
46 | Someone looking for a perl for Win16 might look to Laszlo Molnar's djgpp |
c355f4f4 |
47 | port in http://www.cpan.org/ports/#msdos , which comes with clear |
d92eb7b0 |
48 | installation instructions. A simple installation guide for MS-DOS using |
87275199 |
49 | Ilya Zakharevich's OS/2 port is available at |
50 | http://www.cs.ruu.nl/%7Epiet/perl5dos.html |
51 | and similarly for Windows 3.1 at http://www.cs.ruu.nl/%7Epiet/perlwin3.html . |

b68463f7 |
53 | =head2 I don't have a C compiler. How can I build my own Perl interpreter? |
3fe9a6f1 |
54 | |
55 | Since you don't have a C compiler, you're doomed and your vendor |
56 | should be sacrificed to the Sun gods. But that doesn't help you. |
57 | |
58 | What you need to do is get a binary version of gcc for your system |
59 | first. Consult the Usenet FAQs for your operating system for |
60 | information on where to get such a binary version. |
61 | |
b68463f7 |
62 | =head2 I copied the perl binary from one machine to another, but scripts don't work. |
68dc0745 |
63 | |
64 | That's probably because you forgot libraries, or library paths differ. |
65 | You really should build the whole distribution on the machine it will |
66 | eventually live on, and then type C<make install>. Most other |
67 | approaches are doomed to failure. |
68 | |
69 | One simple way to check that things are in the right place is to print out |
a6dd486b |
70 | the hard-coded @INC that perl looks through for libraries: |
68dc0745 |
71 | |
f0d19b68 |
72 | % perl -le 'print for @INC' |
68dc0745 |
73 | |
a6dd486b |
74 | If this command lists any paths that don't exist on your system, then you |
68dc0745 |
75 | may need to move the appropriate libraries to these locations, or create |
87275199 |
76 | symbolic links, aliases, or shortcuts appropriately. @INC is also printed as |
65acb1b1 |
77 | part of the output of |
78 | |
79 | % perl -V |
68dc0745 |
80 | |
c355f4f4 |
81 | You might also want to check out |
13a2d996 |
82 | L<perlfaq8/"How do I keep my own module/library directory?">. |
3fe9a6f1 |
83 | |
68dc0745 |
84 | =head2 I grabbed the sources and tried to compile but gdbm/dynamic loading/malloc/linking/... failed. How do I make it work? |
85 | |
86 | Read the F<INSTALL> file, which is part of the source distribution. |
65acb1b1 |
87 | It describes in detail how to cope with most idiosyncrasies that the |
68dc0745 |
88 | Configure script can't work around for any given system or |
89 | architecture. |
90 | |
91 | =head2 What modules and extensions are available for Perl? What is CPAN? What does CPAN/src/... mean? |
92 | |
49d635f9 |
93 | CPAN stands for Comprehensive Perl Archive Network, a ~1.2Gb archive |
c355f4f4 |
94 | replicated on nearly 200 machines all over the world. CPAN contains |
46fc3d4c |
95 | source code, non-native ports, documentation, scripts, and many |
68dc0745 |
96 | third-party modules and extensions, designed for everything from |
97 | commercial database interfaces to keyboard/screen control to web |
c355f4f4 |
98 | walking and CGI scripts. The master web site for CPAN is |
99 | http://www.cpan.org/ and there is the CPAN Multiplexer at |
a93751fa |
100 | http://www.cpan.org/CPAN.html which will choose a mirror near you |
c355f4f4 |
101 | via DNS. See http://www.perl.com/CPAN (without a slash at the |
102 | end) for how this process works. Also, http://mirror.cpan.org/ |
103 | has a nice interface to the http://www.cpan.org/MIRRORED.BY |
104 | mirror directory. |
105 | |
106 | See the CPAN FAQ at http://www.cpan.org/misc/cpan-faq.html for |
107 | answers to the most frequently asked questions about CPAN |
108 | including how to become a mirror. |
68dc0745 |
109 | |
110 | CPAN/path/... is a naming convention for files available on CPAN |
111 | sites. CPAN indicates the base directory of a CPAN mirror, and the |
112 | rest of the path is the path from that directory to the file. For |
113 | instance, if you're using ftp://ftp.funet.fi/pub/languages/perl/CPAN |
7ed4b849 |
114 | as your CPAN site, the file CPAN/misc/japh is downloadable as |
68dc0745 |
115 | ftp://ftp.funet.fi/pub/languages/perl/CPAN/misc/japh . |
116 | |
c355f4f4 |
117 | Considering that there are close to two thousand existing modules in |
118 | the archive, one probably exists to do nearly anything you can think of. |
87275199 |
119 | Current categories under CPAN/modules/by-category/ include Perl core |
68dc0745 |
120 | modules; development support; operating system interfaces; networking, |
121 | devices, and interprocess communication; data type utilities; database |
122 | interfaces; user interfaces; interfaces to other languages; filenames, |
123 | file systems, and file locking; internationalization and locale; world |
124 | wide web support; server and daemon utilities; archiving and |
125 | compression; image manipulation; mail and news; control flow |
126 | utilities; filehandle and I/O; Microsoft Windows modules; and |
127 | miscellaneous modules. |
128 | |
c355f4f4 |
129 | See http://www.cpan.org/modules/00modlist.long.html or |
130 | http://search.cpan.org/ for a more complete list of modules by category. |
131 | |

132 | CPAN is not affiliated with O'Reilly Media. |

68dc0745 |
134 | =head2 Is there an ISO or ANSI certified version of Perl? |
135 | |
136 | Certainly not. Larry expects that he'll be certified before Perl is. |
137 | |
138 | =head2 Where can I get information on Perl? |
139 | |
87275199 |
140 | The complete Perl documentation is available with the Perl distribution. |
141 | If you have Perl installed locally, you probably have the documentation |
5a964f20 |
142 | installed as well: type C<man perl> if you're on a system resembling Unix. |
143 | This will lead you to other important man pages, including how to set your |
144 | $MANPATH. If you're not on a Unix system, access to the documentation |
a6dd486b |
145 | will be different; for example, documentation might only be in HTML format. All |
b68463f7 |
146 | proper perl installations have fully-accessible documentation. |
68dc0745 |
147 | |
148 | You might also try C<perldoc perl> in case your system doesn't |
149 | have a proper man command, or it's been misinstalled. If that doesn't |
150 | work, try looking in /usr/local/lib/perl5/pod for documentation. |
151 | |
9e72e4c6 |
152 | If all else fails, consult http://perldoc.perl.org/ which has the |
153 | complete documentation in HTML and PDF format. |
68dc0745 |
154 | |
a6dd486b |
155 | Many good books have been written about Perl--see the section below |
68dc0745 |
156 | for more details. |
157 | |
65acb1b1 |
158 | Tutorial documents are included in current or upcoming Perl releases |
a6dd486b |
159 | include L<perltoot> for objects or L<perlboot> for a beginner's |
160 | approach to objects, L<perlopentut> for file opening semantics, |
161 | L<perlreftut> for managing references, L<perlretut> for regular |
162 | expressions, L<perlthrtut> for threads, L<perldebtut> for debugging, |
163 | and L<perlxstut> for linking C and Perl together. There may be more |

169 | =head2 What are the Perl newsgroups on Usenet? Where do I post questions? |
68dc0745 |
170 | |
04d666b1 |
171 | Several groups devoted to the Perl language are on Usenet: |
68dc0745 |
172 | |
173 | comp.lang.perl.announce Moderated announcement group |
04d666b1 |
174 | comp.lang.perl.misc High traffic general Perl discussion |
175 | comp.lang.perl.moderated Moderated discussion group |
68dc0745 |
176 | comp.lang.perl.modules Use and development of Perl modules |
177 | comp.lang.perl.tk Using Tk (and X) from Perl |
178 | |
179 | comp.infosystems.www.authoring.cgi Writing CGI scripts for the Web. |
180 | |
04d666b1 |
181 | Some years ago, comp.lang.perl was divided into those groups, and |
182 | comp.lang.perl itself officially removed. While that group may still |
183 | be found on some news servers, it is unwise to use it, because |
184 | postings there will not appear on news servers which honour the |
185 | official list of group names. Use comp.lang.perl.misc for topics |
186 | which do not have a more-appropriate specific group. |
83a70550 |
187 | |
04d666b1 |
188 | There is also a Usenet gateway to Perl mailing lists sponsored by |
189 | perl.org at nntp://nntp.perl.org , a web interface to the same lists |
190 | at http://nntp.perl.org/group/ and these lists are also available |
191 | under the C<perl.*> hierarchy at http://groups.google.com . Other |
192 | groups are listed at http://lists.perl.org/ ( also known as |
193 | http://lists.cpan.org/ ). |
194 | |
6670e5e7 |
195 | A nice place to ask questions is the PerlMonks site, |
04d666b1 |
196 | http://www.perlmonks.org/ , or the Perl Beginners mailing list |
197 | http://lists.perl.org/showlist.cgi?name=beginners . |
83a70550 |
198 | |
199 | Note that none of the above are supposed to write your code for you: |
200 | asking questions about particular problems or general advice is fine, |
201 | but asking someone to write your code for free is not very cool. |
68dc0745 |
202 | |
203 | =head2 Where should I post source code? |
204 | |
65acb1b1 |
205 | You should post source code to whichever group is most appropriate, but |
206 | feel free to cross-post to comp.lang.perl.misc. If you want to cross-post |
207 | to alt.sources, please make sure it follows their posting standards, |
208 | including setting the Followup-To header line to NOT include alt.sources; |
f224927c |
209 | see their FAQ ( http://www.faqs.org/faqs/alt-sources-intro/ ) for details. |
68dc0745 |
210 | |
c355f4f4 |
211 | If you're just looking for software, first use Google |
f05bbc40 |
212 | ( http://www.google.com ), Google's usenet search interface |
197aec24 |
213 | ( http://groups.google.com ), and CPAN Search ( http://search.cpan.org ). |
0bc0ad85 |
214 | This is faster and more productive than just posting a request. |

216 | =head2 Perl Books |
217 | |
c98c5709 |
218 | A number of books on Perl and/or CGI programming are available. A few |
6670e5e7 |
219 | of these are good, some are OK, but many aren't worth your money. |
c98c5709 |
220 | There is a list of these books, some with extensive reviews, at |
9e72e4c6 |
221 | http://books.perl.org/ . If you don't see your book listed here, you |
222 | can write to perlfaq-workers@perl.org . |

409 | The first (and for a long time, only) periodical devoted to All Things Perl, |
41eb6b36 |
410 | I<The Perl Journal> contains tutorials, demonstrations, case studies, |
e00b594c |
411 | announcements, contests, and much more. I<TPJ> has columns on web |
5a964f20 |
412 | development, databases, Win32 Perl, graphical programming, regular |
41eb6b36 |
413 | expressions, and networking, and sponsors the Obfuscated Perl Contest |
6670e5e7 |
414 | and the Perl Poetry Contests. Beginning in November 2002, TPJ moved to a |
415 | reader-supported monthly e-zine format in which subscribers can download |
793f5136 |
416 | issues as PDF documents. For more details on TPJ, see http://www.tpj.com/ |
41eb6b36 |
417 | |
418 | Beyond this, magazines that frequently carry quality articles on |
ed8cf1fe |
419 | Perl are I<The Perl Review> ( http://www.theperlreview.com ), |
41eb6b36 |
420 | I<Unix Review> ( http://www.unixreview.com/ ), |

430 | =head2 What mailing lists are there for Perl? |
68dc0745 |
431 | |
87275199 |
432 | Most of the major modules (Tk, CGI, libwww-perl) have their own |
68dc0745 |
433 | mailing lists. Consult the documentation that came with the module for |
c355f4f4 |
434 | subscription information. |
68dc0745 |
435 | |
ccbb3b41 |
436 | A comprehensive list of Perl related mailing lists can be found at: |
437 | |

438 | http://lists.perl.org/ |

440 | =head2 Where are the archives for comp.lang.perl.misc? |
68dc0745 |
441 | |
b0bd3af0 |
442 | The Google search engine now carries archived and searchable newsgroup |
197aec24 |
443 | content. |

447 | If you have a question, you can be sure someone has already asked the |
448 | same question at some point on c.l.p.m. It requires some time and patience |
449 | to sift through all the content but often you will find the answer you |
450 | seek. |

452 | =head2 Where can I buy a commercial version of perl? |
68dc0745 |
453 | |
b68463f7 |
454 | In a real sense, perl already I<is> commercial software: it has a license |
65acb1b1 |
455 | that you can grab and carefully read to your manager. It is distributed |
456 | in releases and comes in well-defined packages. There is a very large |
457 | user community and an extensive literature. The comp.lang.perl.* |
458 | newsgroups and several of the mailing lists provide free answers to your |
459 | questions in near real-time. Perl has traditionally been supported by |
8305e449 |
460 | Larry, scores of software designers and developers, and myriad |
65acb1b1 |
461 | programmers, all working for free to create a useful thing to make life |
462 | better for everyone. |
68dc0745 |
463 | |
464 | However, these answers may not suffice for managers who require a |
65acb1b1 |
465 | purchase order from a company whom they can sue should anything go awry. |
466 | Or maybe they need very serious hand-holding and contractual obligations. |
b68463f7 |
467 | Shrink-wrapped CDs with perl on them are available from several sources if |
468 | that will help. For example, many Perl books include a distribution of perl, |
a6dd486b |
469 | as do the O'Reilly Perl Resource Kits (in both the Unix flavor |
65acb1b1 |
470 | and in the proprietary Microsoft flavor); the free Unix distributions |
b68463f7 |
471 | also all come with perl. |
68dc0745 |
472 | |
68dc0745 |
473 | =head2 Where do I send bug reports? |
474 | |
475 | If you are reporting a bug in the perl interpreter or the modules |
87275199 |
476 | shipped with Perl, use the I<perlbug> program in the Perl distribution or |
b68463f7 |
477 | mail your report to perlbug@perl.org or at http://rt.perl.org/perlbug/ . |
478 | |
479 | For Perl modules, you can submit bug reports to the Request Tracker set |
480 | up at http://rt.cpan.org . |
68dc0745 |
481 | |
46fc3d4c |
482 | If you are posting a bug with a non-standard port (see the answer to |
b68463f7 |
483 | "What platforms is perl available for?"), a binary distribution, or a |
46fc3d4c |
484 | non-standard module (such as Tk, CGI, etc), then please see the |
68dc0745 |
485 | documentation that came with it to determine the correct place to post |
486 | bugs. |
487 | |
5a964f20 |
488 | Read the perlbug(1) man page (perl5.004 or later) for more information. |

498 | general support services to the Perl community, including the hosting |
499 | of mailing lists, web sites, and other services. The web site |
500 | http://www.perl.org/ is a general advocacy site for the Perl language, |
501 | and there are many other sub-domains for special topics, such as |
