131 | .IX Title "PERLBS2000 1" | |
132 | .TH PERLBS2000 1 "2006-01-07" "perl v5.8.8" "Perl Programmers Reference Guide" | |
133 | .SH "NAME" | |
134 | README.BS2000 \- building and installing Perl for BS2000. | |
135 | .SH "SYNOPSIS" | |
136 | .IX Header "SYNOPSIS" | |
137 | This document will help you Configure, build, test and install Perl | |
138 | on \s-1BS2000\s0 in the \s-1POSIX\s0 subsystem. | |
139 | .SH "DESCRIPTION" | |
140 | .IX Header "DESCRIPTION" | |
141 | This is a ported perl for the \s-1POSIX\s0 subsystem in \s-1BS2000\s0 \s-1VERSION\s0 \s-1OSD\s0 | |
142 | V3.1A or later. It may work on other versions, but we started porting | |
143 | and testing it with 3.1A and are currently using Version V4.0A. | |
144 | .PP | |
145 | You may need the following \s-1GNU\s0 programs in order to install perl: | |
146 | .Sh "gzip on \s-1BS2000\s0" | |
147 | .IX Subsection "gzip on BS2000" | |
148 | We used version 1.2.4, which could be installed out of the box with | |
149 | one failure during 'make check'. | |
150 | .Sh "bison on \s-1BS2000\s0" | |
151 | .IX Subsection "bison on BS2000" | |
152 | The yacc coming with \s-1BS2000\s0 \s-1POSIX\s0 didn't work for us. So we had to | |
153 | use bison. We had to make a few changes to perl in order to use the | |
154 | pure (reentrant) parser of bison. We used version 1.25, but we had to | |
155 | add a few changes due to \s-1EBCDIC\s0. See below for more details | |
156 | concerning yacc. | |
157 | .Sh "Unpacking Perl Distribution on \s-1BS2000\s0" | |
158 | .IX Subsection "Unpacking Perl Distribution on BS2000" | |
159 | To extract an \s-1ASCII\s0 tar archive on \s-1BS2000\s0 \s-1POSIX\s0 you need an \s-1ASCII\s0 | |
160 | filesystem (we used the mountpoint /usr/local/ascii for this). Now | |
161 | you extract the archive in the \s-1ASCII\s0 filesystem without | |
162 | I/O\-conversion: | |
163 | .PP | |
164 | cd /usr/local/ascii | |
165 | export IO_CONVERSION=NO | |
166 | gunzip < /usr/local/src/perl.tar.gz | pax \-r | |
167 | .PP | |
168 | You may ignore the error message for the first element of the archive | |
169 | (this doesn't look like a tar archive / skipping to next file...), | |
170 | it's only the directory which will be created automatically anyway. | |
171 | .PP | |
172 | After extracting the archive you copy the whole directory tree to your | |
173 | \&\s-1EBCDIC\s0 filesystem. \fBThis time you use I/O\-conversion\fR: | |
174 | .PP | |
175 | cd /usr/local/src | |
176 | IO_CONVERSION=YES | |
177 | cp \-r /usr/local/ascii/perl5.005_02 ./ | |
178 | .Sh "Compiling Perl on \s-1BS2000\s0" | |
179 | .IX Subsection "Compiling Perl on BS2000" | |
180 | There is a \*(L"hints\*(R" file for \s-1BS2000\s0 called hints.posix\-bc (because | |
181 | posix-bc is the \s-1OS\s0 name given by `uname`) that specifies the correct | |
182 | values for most things. The major problem is (of course) the \s-1EBCDIC\s0 | |
183 | character set. We have german \s-1EBCDIC\s0 version. | |
184 | .PP | |
185 | Because of our problems with the native yacc we used \s-1GNU\s0 bison to | |
186 | generate a pure (=reentrant) parser for perly.y. So our yacc is | |
187 | really the following script: | |
188 | .PP | |
189 | \&\-\-\-\-\-8<\-\-\-\-\-/usr/local/bin/yacc\-\-\-\-\-8<\-\-\-\-\- | |
190 | #! /usr/bin/sh | |

194 | # save parameters: | |
195 | params="\*(L" | |
196 | while [[ $# \-gt 1 ]]; do | |
197 | params=\*(R"$params \f(CW$1\fR" | |
198 | shift | |
199 | done | |
200 | .PP | |
201 | # add flag \f(CW%pure_parser:\fR | |
202 | .PP | |
203 | tmpfile=/tmp/bison.$$.y | |
204 | echo \f(CW%pure_parser\fR > \f(CW$tmpfile\fR | |
205 | cat \f(CW$1\fR >> \f(CW$tmpfile\fR | |
206 | .PP | |
207 | # call bison: | |
208 | .PP | |
209 | echo \*(L"/usr/local/bin/bison \-\-yacc \f(CW$params\fR \f(CW$1\fR\et\et\et(Pure Parser)\*(R" | |

211 | .PP | |
212 | # cleanup: | |
213 | .PP | |
214 | rm \-f \f(CW$tmpfile\fR | |
215 | \&\-\-\-\-\-8<\-\-\-\-\-\-\-\-\-\-8<\-\-\-\-\- | |
216 | .PP | |
217 | We still use the normal yacc for a2p.y though!!! We made a softlink | |
218 | called byacc to distinguish between the two versions: | |
219 | .PP | |
220 | ln \-s /usr/bin/yacc /usr/local/bin/byacc | |
221 | .PP | |
222 | We build perl using \s-1GNU\s0 make. We tried the native make once and it | |
223 | worked too. | |
224 | .Sh "Testing Perl on \s-1BS2000\s0" | |
225 | .IX Subsection "Testing Perl on BS2000" | |
226 | We still got a few errors during \f(CW\*(C`make test\*(C'\fR. Some of them are the | |
227 | result of using bison. Bison prints \fIparser error\fR instead of \fIsyntax | |
228 | error\fR, so we may ignore them. The following list shows | |
229 | our errors, your results may differ: | |

241 | .Sh "Installing Perl on \s-1BS2000\s0" | |
242 | .IX Subsection "Installing Perl on BS2000" | |
243 | We have no nroff on \s-1BS2000\s0 \s-1POSIX\s0 (yet), so we ignored any errors while | |
244 | installing the documentation. | |
245 | .Sh "Using Perl in the Posix-Shell of \s-1BS2000\s0" | |
246 | .IX Subsection "Using Perl in the Posix-Shell of BS2000" | |
247 | \&\s-1BS2000\s0 \s-1POSIX\s0 doesn't support the shebang notation | |
248 | (\f(CW\*(C`#!/usr/local/bin/perl\*(C'\fR), so you have to use the following lines | |
249 | instead: | |
250 | .PP | |
251 | : # use perl | |
252 | eval 'exec /usr/local/bin/perl \-S \f(CW$0\fR ${1+\*(L"$@\*(R"}' | |
253 | if \f(CW$running_under_some_shell\fR; | |
254 | .ie n .Sh "Using Perl in ""native"" \s-1BS2000\s0" | |
255 | .el .Sh "Using Perl in ``native'' \s-1BS2000\s0" | |
256 | .IX Subsection "Using Perl in native BS2000" | |
257 | We don't have much experience with this yet, but try the following: | |
258 | .PP | |
259 | Copy your Perl executable to a \s-1BS2000\s0 \s-1LLM\s0 using bs2cp: | |
260 | .PP | |
261 | \&\f(CW\*(C`bs2cp /usr/local/bin/perl 'bs2:perl(perl,l)'\*(C'\fR | |
262 | .PP | |
263 | Now you can start it with the following (\s-1SDF\s0) command: | |
264 | .PP | |
265 | \&\f(CW\*(C`/START\-PROG FROM\-FILE=*MODULE(PERL,PERL),PROG\-MODE=*ANY,RUN\-MODE=*ADV\*(C'\fR | |
266 | .PP | |
267 | First you get the \s-1BS2000\s0 commandline prompt ('*'). Here you may enter | |
268 | your parameters, e.g. \f(CW\*(C`\-e 'print "Hello World!\e\en";'\*(C'\fR (note the | |
269 | double backslash!) or \f(CW\*(C`\-w\*(C'\fR and the name of your Perl script. | |
270 | Filenames starting with \f(CW\*(C`/\*(C'\fR are searched in the Posix filesystem, | |
271 | others are searched in the \s-1BS2000\s0 filesystem. You may even use | |
272 | wildcards if you put a \f(CW\*(C`%\*(C'\fR in front of your filename (e.g. \f(CW\*(C`\-w | |
273 | checkfiles.pl %*.c\*(C'\fR). Read your C/\*(C+ manual for additional | |
274 | possibilities of the commandline prompt (look for | |
275 | \&\s-1PARAMETER\-PROMPTING\s0). | |
276 | .Sh "Floating point anomalies on \s-1BS2000\s0" | |
277 | .IX Subsection "Floating point anomalies on BS2000" | |
278 | There appears to be a bug in the floating point implementation on \s-1BS2000\s0 \s-1POSIX\s0 | |
279 | systems such that calling \fIint()\fR on the product of a number and a small | |
280 | magnitude number is not the same as calling \fIint()\fR on the quotient of | |
281 | that number and a large magnitude number. For example, in the following | |
282 | Perl code: | |
283 | .PP | |
284 | .Vb 4 | |
285 | \& my $x = 100000.0; | |
286 | \& my $y = int($x * 1e-5) * 1e5; # '0' | |
287 | \& my $z = int($x / 1e+5) * 1e5; # '100000' | |
288 | \& print "\e$y is $y and \e$z is $z\en"; # $y is 0 and $z is 100000 | |
289 | .Ve | |
290 | .PP | |
291 | Although one would expect the quantities \f(CW$y\fR and \f(CW$z\fR to be the same and equal | |
292 | to 100000 they will differ and instead will be 0 and 100000 respectively. | |
293 | .Sh "Using PerlIO and different encodings on \s-1ASCII\s0 and \s-1EBCDIC\s0 partitions" | |
294 | .IX Subsection "Using PerlIO and different encodings on ASCII and EBCDIC partitions" | |
295 | Since version 5.8 Perl uses the new PerlIO on \s-1BS2000\s0. This enables | |
296 | you using different encodings per \s-1IO\s0 channel. For example you may use | |
297 | .PP | |
298 | .Vb 9 | |
299 | \& use Encode; | |
300 | \& open($f, ">:encoding(ascii)", "test.ascii"); | |
301 | \& print $f "Hello World!\en"; | |
302 | \& open($f, ">:encoding(posix-bc)", "test.ebcdic"); | |
303 | \& print $f "Hello World!\en"; | |
304 | \& open($f, ">:encoding(latin1)", "test.latin1"); | |
305 | \& print $f "Hello World!\en"; | |
306 | \& open($f, ">:encoding(utf8)", "test.utf8"); | |
307 | \& print $f "Hello World!\en"; | |
308 | .Ve | |
309 | .PP | |
310 | to get two files containing \*(L"Hello World!\en\*(R" in \s-1ASCII\s0, \s-1EBCDIC\s0, \s-1ISO\s0 | |
311 | Latin\-1 (in this example identical to \s-1ASCII\s0) respective UTF-EBCDIC (in | |
312 | this example identical to normal \s-1EBCDIC\s0). See the documentation of | |
313 | Encode::PerlIO for details. | |
314 | .PP | |
315 | As the PerlIO layer uses raw \s-1IO\s0 internally, all this totally ignores | |
316 | the type of your filesystem (\s-1ASCII\s0 or \s-1EBCDIC\s0) and the \s-1IO_CONVERSION\s0 | |
317 | environment variable. If you want to get the old behavior, that the | |
318 | \&\s-1BS2000\s0 \s-1IO\s0 functions determine conversion depending on the filesystem | |
319 | PerlIO still is your friend. You use \s-1IO_CONVERSION\s0 as usual and tell | |
320 | Perl, that it should use the native \s-1IO\s0 layer: | |
321 | .PP | |
322 | .Vb 2 | |
323 | \& export IO_CONVERSION=YES | |
324 | \& export PERLIO=stdio | |
325 | .Ve | |
326 | .PP | |
327 | Now your \s-1IO\s0 would be \s-1ASCII\s0 on \s-1ASCII\s0 partitions and \s-1EBCDIC\s0 on \s-1EBCDIC\s0 | |
328 | partitions. See the documentation of PerlIO (without \f(CW\*(C`Encode::\*(C'\fR!) | |
329 | for further posibilities. | |
