|---|
| 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 | |
|---|
| 59 | ixemul-46.0-bin.lha |
|---|
| 60 | ixemul-46.0-env-bin.lha |
|---|
| 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 | |
|---|
| 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 | |
|---|
| 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 | |
|---|
| 221 | Some tests will be skipped because they need the fork() function: |
|---|
| 222 | |
|---|
| 223 | F<io/pipe.t>, F<op/fork.t>, F<lib/filehand.t>, F<lib/open2.t>, F<lib/open3.t>, |
|---|
| 224 | F<lib/io_pipe.t>, F<lib/io_sock.t> |
|---|
| 225 | |
|---|
| 226 | =head2 Installing the built perl |
|---|
| 227 | |
|---|
| 228 | Run |
|---|
| 229 | |
|---|
| 230 | make install |
