16 | =head1 SYNOPSIS | |
17 | ||
18 | One can read this document in the following formats: | |
19 | ||
20 | man perlamiga | |
21 | multiview perlamiga.guide | |
22 | ||
23 | to list some (not all may be available simultaneously), or it may | |
24 | be read I<as is>: either as F<README.amiga>, or F<pod/perlamiga.pod>. | |

62 | ||
63 | =over 6 | |
64 | ||
65 | =item B<Unix emulation for AmigaOS: ixemul.library> | |
66 | ||
67 | You need the Unix emulation for AmigaOS, whose most important part is | |
68 | B<ixemul.library>. For a minimum setup, get the latest versions | |
69 | of the following packages from the Aminet archives | |
70 | ( http://www.aminet.net/~aminet/ ): | |
71 | ||
72 | ixemul-bin | |
73 | ixemul-env-bin | |
74 | pdksh-bin | |
75 | ||
76 | Note also that this is a minimum setup; you might want to add other | |
77 | packages of B<ADE> (the I<Amiga Developers Environment>). | |
78 | ||
79 | =item B<Version of Amiga OS> | |
80 | ||
81 | You need at the very least AmigaOS version 2.0. Recommended is version 3.1. | |
82 | ||
83 | =back | |
84 | ||
85 | =head2 Starting Perl programs under AmigaOS | |
86 | ||
87 | Start your Perl program F<foo> with arguments C<arg1 arg2 arg3> the | |
88 | same way as on any other platform, by | |
89 | ||
90 | perl foo arg1 arg2 arg3 | |
91 | ||
92 | If you want to specify perl options C<-my_opts> to the perl itself (as | |
93 | opposed to your program), use | |
94 | ||
95 | perl -my_opts foo arg1 arg2 arg3 | |
96 | ||
97 | Alternately, you can try to get a replacement for the system's B<Execute> | |
98 | command that honors the #!/usr/bin/perl syntax in scripts and set the s-Bit | |
99 | of your scripts. Then you can invoke your scripts like under UNIX with | |
100 | ||
101 | foo arg1 arg2 arg3 | |
102 | ||
103 | (Note that having *nixish full path to perl F</usr/bin/perl> is not | |
104 | necessary, F<perl> would be enough, but having full path would make it | |
105 | easier to use your script under *nix.) | |
106 | ||
107 | =head2 Shortcomings of Perl under AmigaOS | |
108 | ||
109 | Perl under AmigaOS lacks some features of perl under UNIX because of | |
110 | deficiencies in the UNIX-emulation, most notably: | |
111 | ||
112 | =over 6 | |
113 | ||
114 | =item * | |
115 | ||
116 | fork() | |
117 | ||
118 | =item * | |
119 | ||
120 | some features of the UNIX filesystem regarding link count and file dates | |
121 | ||
122 | =item * | |
123 | ||
124 | inplace operation (the -i switch) without backup file | |
125 | ||
126 | =item * | |
127 | ||
128 | umask() works, but the correct permissions are only set when the file is | |
129 | finally close()d | |
130 | ||
131 | =back | |
132 | ||
133 | =head1 INSTALLATION | |
134 | ||
135 | Change to the installation directory (most probably ADE:), and | |
136 | extract the binary distribution: | |
137 | ||
138 | lha -mraxe x perl-$VERSION-bin.lha | |
139 | ||
140 | or | |
141 | ||
142 | tar xvzpf perl-$VERSION-bin.tgz | |
143 | ||
144 | (Of course you need lha or tar and gunzip for this.) | |
145 | ||
146 | For installation of the Unix emulation, read the appropriate docs. | |
147 | ||
148 | =head1 Accessing documentation | |
149 | ||
150 | =head2 Manpages for Perl on AmigaOS | |
151 | ||
152 | If you have C<man> installed on your system, and you installed perl | |
153 | manpages, use something like this: | |
154 | ||
155 | man perlfunc | |
156 | man less | |
157 | man ExtUtils.MakeMaker | |
158 | ||
159 | to access documentation for different components of Perl. Start with | |
160 | ||
161 | man perl | |
162 | ||
163 | Note: You have to modify your man.conf file to search for manpages | |
164 | in the /ade/lib/perl5/man/man3 directory, or the man pages for the | |
165 | perl library will not be found. | |
166 | ||
167 | Note that dot (F<.>) is used as a package separator for documentation | |
168 | for packages, and as usual, sometimes you need to give the section - C<3> | |
169 | above - to avoid shadowing by the I<less(1) manpage>. | |
170 | ||
171 | ||
172 | =head2 Perl HTML Documentation on AmigaOS | |
173 | ||
174 | If you have some WWW browser available, you can build B<HTML> docs. | |
175 | Cd to directory with F<.pod> files, and do like this | |
176 | ||
177 | cd /ade/lib/perl5/pod | |
178 | pod2html | |
179 | ||
180 | After this you can direct your browser the file F<perl.html> in this | |
181 | directory, and go ahead with reading docs. | |
182 | ||
183 | Alternatively you may be able to get these docs prebuilt from C<CPAN>. | |
184 | ||
185 | =head2 Perl GNU Info Files on AmigaOS | |
186 | ||
187 | Users of C<Emacs> would appreciate it very much, especially with | |
188 | C<CPerl> mode loaded. You need to get latest C<pod2info> from C<CPAN>, | |
189 | or, alternately, prebuilt info pages. | |
190 | ||
191 | =head2 Perl LaTeX Documentation on AmigaOS | |
192 | ||
193 | Can be constructed using C<pod2latex>. | |
194 | ||
195 | =head1 BUILDING PERL ON AMIGAOS | |
196 | ||
197 | Here we discuss how to build Perl under AmigaOS. | |
198 | ||
199 | =head2 Build Prerequisites for Perl on AmigaOS | |
200 | ||
201 | You need to have the latest B<ixemul> (Unix emulation for Amiga) | |
202 | from Aminet. | |
203 | ||
204 | =head2 Getting the Perl Source for AmigaOS | |
205 | ||
206 | You can either get the latest perl-for-amiga source from Ninemoons | |
207 | and extract it with: | |
208 | ||
209 | tar xvzpf perl-$VERSION-src.tgz | |
210 | ||
211 | or get the official source from CPAN: | |
212 | ||
213 | http://www.cpan.org/src/5.0 | |
214 | ||
215 | Extract it like this | |
216 | ||
217 | tar xvzpf perl-$VERSION.tar.gz | |
218 | ||
219 | You will see a message about errors while extracting F<Configure>. This | |
220 | is normal and expected. (There is a conflict with a similarly-named file | |
221 | F<configure>, but it causes no harm.) | |
222 | ||
223 | =head2 Making Perl on AmigaOS | |
224 | ||
225 | Remember to use a hefty wad of stack (I use 2000000) | |
226 | ||
227 | sh configure.gnu --prefix=/gg | |
228 | ||
229 | Now type | |
230 | ||
231 | make depend | |
232 | ||
233 | Now! | |
234 | ||
235 | make | |
236 | ||
237 | =head2 Testing Perl on AmigaOS | |
238 | ||
239 | Now run | |
240 | ||
241 | make test | |
242 | ||
243 | Some tests will be skipped because they need the fork() function: | |
244 | ||
245 | F<io/pipe.t>, F<op/fork.t>, F<lib/filehand.t>, F<lib/open2.t>, F<lib/open3.t>, | |
246 | F<lib/io_pipe.t>, F<lib/io_sock.t> | |
247 | ||
248 | =head2 Installing the built Perl on AmigaOS | |
249 | ||
250 | Run | |
251 | ||
252 | make install | |
253 | ||
254 | =head1 PERL 5.8.0 BROKEN IN AMIGAOS | |
255 | ||
256 | As told above, Perl 5.6.1 was still good in AmigaOS, as was 5.7.2. | |
257 | After Perl 5.7.2 (change #11423, see the Changes file, and the file | |
258 | pod/perlhack.pod for how to get the individual changes) Perl dropped | |
259 | its internal support for vfork(), and that was very probably the step | |
260 | that broke AmigaOS (since the ixemul library has only vfork). | |
261 | The build finally fails when the ext/DynaLoader is being built, and | |
262 | PERL ends up as "0" in the produced Makefile, trying to run "0" does | |
263 | not quite work. Also, executing miniperl in backticks seems to | |
264 | generate nothing: very probably related to the (v)fork problems. | |
265 | B<Fixing the breakage requires someone quite familiar with the ixemul | |
266 | library, and how one is supposed to run external commands in AmigaOS | |
267 | without fork().> | |
