53 | =item B<Unix emulation for AmigaOS: ixemul.library> | |
54 | ||
55 | You need the Unix emulation for AmigaOS, whose most important part is | |
56 | B<ixemul.library>. For a minimum setup, get the following archives from | |
57 | ftp://ftp.ninemoons.com/pub/ade/current or a mirror: | |
58 | ||
9f89dd86 NP |
59 | ixemul-46.0-bin.lha |
60 | ixemul-46.0-env-bin.lha | |
0a753a76 | 61 | pdksh-4.9-bin.lha |
62 | ADE-misc-bin.lha | |
63 | ||
64 | Note that there might be newer versions available by the time you read | |
65 | this. | |
66 | ||
67 | Note also that this is a minimum setup; you might want to add other | |
68 | packages of B<ADE> (the I<Amiga Developers Environment>). | |
69 | ||
70 | =item B<Version of Amiga OS> | |
71 | ||
72 | You need at the very least AmigaOS version 2.0. Recommended is version 3.1. | |
73 | ||
74 | =back | |
75 | ||
76 | =head2 Starting Perl programs under AmigaOS | |
77 | ||
78 | Start your Perl program F<foo> with arguments C<arg1 arg2 arg3> the | |
79 | same way as on any other platform, by | |
80 | ||
81 | perl foo arg1 arg2 arg3 | |
82 | ||
83 | If you want to specify perl options C<-my_opts> to the perl itself (as | |
84 | opposed to to your program), use | |
85 | ||
86 | perl -my_opts foo arg1 arg2 arg3 | |
87 | ||
88 | Alternately, you can try to get a replacement for the system's B<Execute> | |
89 | command that honors the #!/usr/bin/perl syntax in scripts and set the s-Bit | |
90 | of your scripts. Then you can invoke your scripts like under UNIX with | |
91 | ||
92 | foo arg1 arg2 arg3 | |
93 | ||
94 | (Note that having *nixish full path to perl F</usr/bin/perl> is not | |
95 | necessary, F<perl> would be enough, but having full path would make it | |
96 | easier to use your script under *nix.) | |
97 | ||
b971f6e4 | 98 | =head2 Shortcomings of Perl under AmigaOS |
99 | ||
100 | Perl under AmigaOS lacks some features of perl under UNIX because of | |
101 | deficiencies in the UNIX-emulation, most notably: | |
102 | ||
103 | =over 6 | |
104 | ||
105 | =item fork() | |
106 | ||
107 | =item some features of the UNIX filesystem regarding link count and file dates | |
108 | ||
109 | =item inplace operation (the -i switch) without backup file | |
110 | ||
111 | =item umask() works, but the correct permissions are only set when the file is | |
112 | finally close()d | |
113 | ||
114 | =back | |
115 | ||
0a753a76 | 116 | =head1 INSTALLATION |
117 | ||
118 | Change to the installation directory (most probably ADE:), and | |
119 | extract the binary distribution: | |
120 | ||
121 | lha -mraxe x perl-5.003-bin.lha | |
122 | ||
123 | or | |
124 | ||
125 | tar xvzpf perl-5.003-bin.tgz | |
126 | ||
127 | (Of course you need lha or tar and gunzip for this.) | |
128 | ||
129 | For installation of the Unix emulation, read the appropriate docs. | |
130 | ||
131 | =head1 Accessing documentation | |
132 | ||
133 | =head2 Manpages | |
134 | ||
135 | If you have C<man> installed on your system, and you installed perl | |
136 | manpages, use something like this: | |
137 | ||
138 | man perlfunc | |
139 | man less | |
140 | man ExtUtils.MakeMaker | |
141 | ||
142 | to access documentation for different components of Perl. Start with | |
143 | ||
144 | man perl | |
145 | ||
146 | Note: You have to modify your man.conf file to search for manpages | |
147 | in the /ade/lib/perl5/man/man3 directory, or the man pages for the | |
148 | perl library will not be found. | |
149 | ||
150 | Note that dot (F<.>) is used as a package separator for documentation | |
151 | for packages, and as usual, sometimes you need to give the section - C<3> | |
152 | above - to avoid shadowing by the I<less(1) manpage>. | |
153 | ||
154 | ||
155 | =head2 B<HTML> | |
156 | ||
157 | If you have some WWW browser available, you can build B<HTML> docs. | |
158 | Cd to directory with F<.pod> files, and do like this | |
159 | ||
160 | cd /ade/lib/perl5/pod | |
161 | pod2html | |
162 | ||
163 | After this you can direct your browser the file F<perl.html> in this | |
164 | directory, and go ahead with reading docs. | |
165 | ||
166 | Alternatively you may be able to get these docs prebuilt from C<CPAN>. | |
167 | ||
168 | =head2 B<GNU> C<info> files | |
169 | ||
170 | Users of C<Emacs> would appreciate it very much, especially with | |
171 | C<CPerl> mode loaded. You need to get latest C<pod2info> from C<CPAN>, | |
172 | or, alternately, prebuilt info pages. | |
173 | ||
174 | =head2 C<LaTeX> docs | |
175 | ||
176 | can be constructed using C<pod2latex>. | |
177 | ||
178 | =head1 BUILD | |
179 | ||
180 | Here we discuss how to build Perl under AmigaOS. | |
181 | ||
182 | =head2 Prerequisites | |
183 | ||
184 | You need to have the latest B<ADE> (Amiga Developers Environment) | |
185 | from ftp://ftp.ninemoons.com/pub/ade/current. | |
186 | Also, you need a lot of free memory, probably at least 8MB. | |
187 | ||
188 | =head2 Getting the perl source | |
189 | ||
190 | You can either get the latest perl-for-amiga source from Ninemoons | |
191 | and extract it with: | |
192 | ||
193 | tar xvzpf perl-5.004-src.tgz | |
194 | ||
195 | or get the official source from CPAN: | |
196 | ||
197 | http://www.perl.com/CPAN/src/5.0 | |
198 | ||
199 | Extract it like this | |
200 | ||
201 | tar xvzpf perl5.004.tar.gz | |
202 | ||
203 | You will see a message about errors while extracting F<Configure>. This | |
204 | is normal and expected. (There is a conflict with a similarly-named file | |
205 | F<configure>, but it causes no harm.) | |
206 | ||
207 | =head2 Making | |
208 | ||
209 | sh configure.gnu --prefix=/ade | |
210 | ||
211 | Now | |
212 | ||
213 | make | |
214 | ||
215 | =head2 Testing | |
216 | ||
217 | Now run | |
218 | ||
219 | make test | |
220 | ||
b971f6e4 | 221 | Some tests will be skipped because they need the fork() function: |

224 | F<lib/io_pipe.t>, F<lib/io_sock.t> | |
0a753a76 | 225 | |
226 | =head2 Installing the built perl | |
227 | ||
228 | Run | |
229 | ||
230 | make install | |
