197aec24 | 3 | perlfaq2 - Obtaining and Learning about Perl ($Revision: 1.18 $, $Date: 2002/12/06 07:40:11 $) |
68dc0745 | 4 | |
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 | ||
11 | =head2 What machines support Perl? Where do I get it? | |
12 | ||
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 GS |
17 | |
18 | Perl builds and runs on a bewildering number of platforms. Virtually | |
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 GS |
22 | |
23 | Binary distributions for some proprietary platforms, including | |
c355f4f4 | 24 | Apple systems, can be found http://www.cpan.org/ports/ directory. |
5e3006a4 GS |
25 | Because these are not part of the standard distribution, they may |
26 | and in fact do differ from the base Perl port in a variety of ways. | |
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 | |
68dc0745 | 33 | =head2 How can I get a binary version of Perl? |
34 | ||
65acb1b1 TC |
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 TC |
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 | |
87275199 | 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 GS |
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 . | |

53 | =head2 I don't have a C compiler on my system. How can I compile perl? | |
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 | ||
68dc0745 | 62 | =head2 I copied the Perl binary from one machine to another, but scripts don't work. |
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 | |
65acb1b1 | 72 | % perl -e 'print join("\n",@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 TC |
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 JH |
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 JH |
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 JH |
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 JH |
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 | ||
06a5f41f | 132 | CPAN is not affiliated with O'Reilly and Associates. |
c355f4f4 | 133 | |
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 GS |
140 | The complete Perl documentation is available with the Perl distribution. |
141 | If you have Perl installed locally, you probably have the documentation | |
5a964f20 TC |
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 |
87275199 | 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 | ||
c355f4f4 JH |
152 | If all else fails, consult http://perldoc.cpan.org/ or |
153 | http://www.perldoc.com/ both offer the complete documentation | |
154 | in html format. | |
68dc0745 | 155 | |
a6dd486b | 156 | Many good books have been written about Perl--see the section below |
68dc0745 | 157 | for more details. |
158 | ||
65acb1b1 | 159 | Tutorial documents are included in current or upcoming Perl releases |
a6dd486b JB |
160 | include L<perltoot> for objects or L<perlboot> for a beginner's |
161 | approach to objects, L<perlopentut> for file opening semantics, | |
162 | L<perlreftut> for managing references, L<perlretut> for regular | |
163 | expressions, L<perlthrtut> for threads, L<perldebtut> for debugging, | |
164 | and L<perlxstut> for linking C and Perl together. There may be more | |
165 | by the time you read this. The following URLs might also be of | |

87275199 | 172 | =head2 What are the Perl newsgroups on Usenet? Where do I post questions? |
68dc0745 | 173 | |
174 | The now defunct comp.lang.perl newsgroup has been superseded by the | |
175 | following groups: | |
176 | ||
177 | comp.lang.perl.announce Moderated announcement group | |
178 | comp.lang.perl.misc Very busy group about Perl in general | |
5a964f20 | 179 | comp.lang.perl.moderated Moderated discussion group |
68dc0745 | 180 | comp.lang.perl.modules Use and development of Perl modules |
181 | comp.lang.perl.tk Using Tk (and X) from Perl | |
182 | ||
183 | comp.infosystems.www.authoring.cgi Writing CGI scripts for the Web. | |
184 | ||
ccbb3b41 IT |
185 | There is also a Usenet gateway to Perl mailing lists sponsored by perl.org at |
186 | nntp://nntp.perl.org , a web interface to the same lists at | |
187 | http://nntp.perl.org/group/ and these lists are also available under the | |
188 | C<perl.*> hierarchy at http://groups.google.com . Other groups are listed at | |
83a70550 JH |
189 | http://lists.perl.org/ ( also known as http://lists.cpan.org/ ). |
190 | ||
191 | A nice place to ask questions is the PerlMonks site, http://www.perlmonks.org/ | |
192 | ||
193 | Note that none of the above are supposed to write your code for you: | |
194 | asking questions about particular problems or general advice is fine, | |
195 | but asking someone to write your code for free is not very cool. | |
68dc0745 | 196 | |
197 | =head2 Where should I post source code? | |
198 | ||
65acb1b1 TC |
199 | You should post source code to whichever group is most appropriate, but |
200 | feel free to cross-post to comp.lang.perl.misc. If you want to cross-post | |
201 | to alt.sources, please make sure it follows their posting standards, | |
202 | including setting the Followup-To header line to NOT include alt.sources; | |
f224927c | 203 | see their FAQ ( http://www.faqs.org/faqs/alt-sources-intro/ ) for details. |
68dc0745 | 204 | |
c355f4f4 | 205 | If you're just looking for software, first use Google |
f05bbc40 | 206 | ( http://www.google.com ), Google's usenet search interface |
197aec24 | 207 | ( http://groups.google.com ), and CPAN Search ( http://search.cpan.org ). |
0bc0ad85 | 208 | This is faster and more productive than just posting a request. |

68dc0745 | 210 | =head2 Perl Books |
211 | ||
7b8d334a | 212 | A number of books on Perl and/or CGI programming are available. A few of |
87275199 | 213 | these are good, some are OK, but many aren't worth your money. Tom |
68dc0745 | 214 | Christiansen maintains a list of these books, some with extensive |
a6dd486b | 215 | reviews, at http://www.perl.com/perl/critiques/index.html . |

41eb6b36 | 378 | I<The Perl Journal> contains tutorials, demonstrations, case studies, |
e00b594c | 379 | announcements, contests, and much more. I<TPJ> has columns on web |
5a964f20 | 380 | development, databases, Win32 Perl, graphical programming, regular |

381 | expressions, and networking, and sponsors the Obfuscated Perl Contest |
382 | and the Perl Poetry Contests. As of mid-2001, the dead tree version | |
6c43ff60 | 383 | of TPJ will be published as a quarterly supplement of SysAdmin |
f05bbc40 | 384 | magazine ( http://www.sysadminmag.com/ ) For more details on TPJ, |
41eb6b36 JH |
385 | see http://www.tpj.com/ |

387 | Beyond this, magazines that frequently carry quality articles on | |
ed8cf1fe | 388 | Perl are I<The Perl Review> ( http://www.theperlreview.com ), |
41eb6b36 JH |
389 | I<Unix Review> ( http://www.unixreview.com/ ), |

401 | To get the best performance, pick a site from the list at |
402 | http://www.cpan.org/SITES.html . From there you can find the quickest | |
403 | site for you. | |
404 | ||
405 | You may also use xx.cpan.org where "xx" is the 2-letter country code | |
406 | for your domain; e.g. Australia would use au.cpan.org. [Note: This | |
407 | only applies to countries that host at least one mirror.] | |

87275199 | 409 | =head2 What mailing lists are there for Perl? |
68dc0745 | 410 | |
87275199 | 411 | Most of the major modules (Tk, CGI, libwww-perl) have their own |
68dc0745 | 412 | mailing lists. Consult the documentation that came with the module for |
c355f4f4 | 413 | subscription information. |

415 | A comprehensive list of Perl related mailing lists can be found at: |

426 | If you have a question, you can be sure someone has already asked the |
427 | same question at some point on c.l.p.m. It requires some time and patience | |
428 | to sift through all the content but often you will find the answer you | |
429 | seek. | |
68dc0745 | 430 | |
68dc0745 | 431 | =head2 Where can I buy a commercial version of Perl? |
432 | ||
a6dd486b | 433 | In a real sense, Perl already I<is> commercial software: it has a license |
65acb1b1 TC |
434 | that you can grab and carefully read to your manager. It is distributed |
435 | in releases and comes in well-defined packages. There is a very large | |
436 | user community and an extensive literature. The comp.lang.perl.* | |
437 | newsgroups and several of the mailing lists provide free answers to your | |
438 | questions in near real-time. Perl has traditionally been supported by | |
8305e449 | 439 | Larry, scores of software designers and developers, and myriad |
65acb1b1 TC |
440 | programmers, all working for free to create a useful thing to make life |
441 | better for everyone. | |
68dc0745 | 442 | |
443 | However, these answers may not suffice for managers who require a | |
65acb1b1 TC |
444 | purchase order from a company whom they can sue should anything go awry. |
445 | Or maybe they need very serious hand-holding and contractual obligations. | |
87275199 | 446 | Shrink-wrapped CDs with Perl on them are available from several sources if |
a6dd486b JB |
447 | that will help. For example, many Perl books include a distribution of Perl, |
448 | as do the O'Reilly Perl Resource Kits (in both the Unix flavor | |
65acb1b1 TC |
449 | and in the proprietary Microsoft flavor); the free Unix distributions |
450 | also all come with Perl. | |

453 | through the Perl Clinic. The following is a commercial from them: | |

68dc0745 | 478 | =head2 Where do I send bug reports? |
479 | ||
480 | If you are reporting a bug in the perl interpreter or the modules | |
87275199 | 481 | shipped with Perl, use the I<perlbug> program in the Perl distribution or |
7f2de2d2 | 482 | mail your report to perlbug@perl.org . |
68dc0745 | 483 | |
46fc3d4c | 484 | If you are posting a bug with a non-standard port (see the answer to |
68dc0745 | 485 | "What platforms is Perl available for?"), a binary distribution, or a |
46fc3d4c | 486 | non-standard module (such as Tk, CGI, etc), then please see the |
68dc0745 | 487 | documentation that came with it to determine the correct place to post |
488 | bugs. | |
489 | ||
5a964f20 | 490 | Read the perlbug(1) man page (perl5.004 or later) for more information. |

506 | Perl Mongers also maintain the perl.org domain to provide general |
507 | support services to the Perl community, including the hosting of mailing | |
508 | lists, web sites, and other services. The web site | |
509 | http://www.perl.org/ is a general advocacy site for the Perl language, | |
510 | and there are many other sub-domains for special topics, such as | |
