53 | |
54 | =head2 Prerequisites |
55 | |
56 | =over 6 |
57 | |
58 | =item B<Unix emulation for AmigaOS: ixemul.library> |
59 | |
60 | You need the Unix emulation for AmigaOS, whose most important part is |
61 | B<ixemul.library>. For a minimum setup, get the following archives from |
f23f9bed |
62 | the Aminet archives (http://www.aminet.net/~aminet/): |
0a753a76 |
63 | |
f23f9bed |
64 | ixemul-bin.lha |
65 | ixemul-env-bin.lha |
66 | pdksh-bin.lha |
0a753a76 |
67 | |
68 | Note that there might be newer versions available by the time you read |
69 | this. |
70 | |
71 | Note also that this is a minimum setup; you might want to add other |
72 | packages of B<ADE> (the I<Amiga Developers Environment>). |
73 | |
74 | =item B<Version of Amiga OS> |
75 | |
76 | You need at the very least AmigaOS version 2.0. Recommended is version 3.1. |
77 | |
78 | =back |
79 | |
80 | =head2 Starting Perl programs under AmigaOS |
81 | |
82 | Start your Perl program F<foo> with arguments C<arg1 arg2 arg3> the |
83 | same way as on any other platform, by |
84 | |
85 | perl foo arg1 arg2 arg3 |
86 | |
87 | If you want to specify perl options C<-my_opts> to the perl itself (as |
88 | opposed to to your program), use |
89 | |
90 | perl -my_opts foo arg1 arg2 arg3 |
91 | |
92 | Alternately, you can try to get a replacement for the system's B<Execute> |
93 | command that honors the #!/usr/bin/perl syntax in scripts and set the s-Bit |
94 | of your scripts. Then you can invoke your scripts like under UNIX with |
95 | |
96 | foo arg1 arg2 arg3 |
97 | |
98 | (Note that having *nixish full path to perl F</usr/bin/perl> is not |
99 | necessary, F<perl> would be enough, but having full path would make it |
100 | easier to use your script under *nix.) |
101 | |
b971f6e4 |
102 | =head2 Shortcomings of Perl under AmigaOS |
103 | |
104 | Perl under AmigaOS lacks some features of perl under UNIX because of |
105 | deficiencies in the UNIX-emulation, most notably: |
106 | |
107 | =over 6 |
108 | |
109 | =item fork() |
110 | |
111 | =item some features of the UNIX filesystem regarding link count and file dates |
112 | |
113 | =item inplace operation (the -i switch) without backup file |
114 | |
115 | =item umask() works, but the correct permissions are only set when the file is |
116 | finally close()d |

118 | =back |
119 | |
0a753a76 |
120 | =head1 INSTALLATION |
121 | |
122 | Change to the installation directory (most probably ADE:), and |
123 | extract the binary distribution: |
124 | |
f23f9bed |
125 | lha -mraxe x perl-$VERSION-bin.lha |
0a753a76 |
126 | |
127 | or |
128 | |
f23f9bed |
129 | tar xvzpf perl-$VERSION-bin.tgz |
0a753a76 |
130 | |
131 | (Of course you need lha or tar and gunzip for this.) |
132 | |
133 | For installation of the Unix emulation, read the appropriate docs. |
134 | |
135 | =head1 Accessing documentation |
136 | |
137 | =head2 Manpages |
138 | |
139 | If you have C<man> installed on your system, and you installed perl |
140 | manpages, use something like this: |
141 | |
142 | man perlfunc |
143 | man less |
144 | man ExtUtils.MakeMaker |
145 | |
146 | to access documentation for different components of Perl. Start with |
147 | |
148 | man perl |
149 | |
150 | Note: You have to modify your man.conf file to search for manpages |
151 | in the /ade/lib/perl5/man/man3 directory, or the man pages for the |
152 | perl library will not be found. |
153 | |
154 | Note that dot (F<.>) is used as a package separator for documentation |
155 | for packages, and as usual, sometimes you need to give the section - C<3> |
156 | above - to avoid shadowing by the I<less(1) manpage>. |
157 | |
158 | |
159 | =head2 B<HTML> |
160 | |
161 | If you have some WWW browser available, you can build B<HTML> docs. |
162 | Cd to directory with F<.pod> files, and do like this |
163 | |
164 | cd /ade/lib/perl5/pod |
165 | pod2html |
166 | |
167 | After this you can direct your browser the file F<perl.html> in this |
168 | directory, and go ahead with reading docs. |
169 | |
170 | Alternatively you may be able to get these docs prebuilt from C<CPAN>. |
171 | |
172 | =head2 B<GNU> C<info> files |
173 | |
174 | Users of C<Emacs> would appreciate it very much, especially with |
175 | C<CPerl> mode loaded. You need to get latest C<pod2info> from C<CPAN>, |
176 | or, alternately, prebuilt info pages. |
177 | |
178 | =head2 C<LaTeX> docs |
179 | |
180 | can be constructed using C<pod2latex>. |
181 | |
182 | =head1 BUILD |
183 | |
184 | Here we discuss how to build Perl under AmigaOS. |
185 | |
186 | =head2 Prerequisites |
187 | |
f23f9bed |
188 | You need to have the latest B<ixemul> (Unix emulation for Amiga) |
189 | from Aminet. |
0a753a76 |
190 | |
191 | =head2 Getting the perl source |
192 | |
193 | You can either get the latest perl-for-amiga source from Ninemoons |
194 | and extract it with: |
195 | |
f23f9bed |
196 | tar xvzpf perl-$VERSION-src.tgz |
0a753a76 |
197 | |
198 | or get the official source from CPAN: |
199 | |
200 | http://www.perl.com/CPAN/src/5.0 |
201 | |
202 | Extract it like this |
203 | |
f23f9bed |
204 | tar xvzpf perl$VERSION.tar.gz |
0a753a76 |
205 | |
206 | You will see a message about errors while extracting F<Configure>. This |
207 | is normal and expected. (There is a conflict with a similarly-named file |
208 | F<configure>, but it causes no harm.) |
209 | |
210 | =head2 Making |
211 | |
212 | sh configure.gnu --prefix=/ade |
213 | |
214 | Now |
215 | |
216 | make |
217 | |
218 | =head2 Testing |
219 | |
220 | Now run |
221 | |
222 | make test |
223 | |
b971f6e4 |
224 | Some tests will be skipped because they need the fork() function: |
0a753a76 |
225 | |
b971f6e4 |
226 | F<io/pipe.t>, F<op/fork.t>, F<lib/filehand.t>, F<lib/open2.t>, F<lib/open3.t>, |
227 | F<lib/io_pipe.t>, F<lib/io_sock.t> |
0a753a76 |
228 | |
229 | =head2 Installing the built perl |
230 | |
231 | Run |
232 | |
233 | make install |
