7 README.vos - Perl for Stratus VOS
11 This file contains notes for building perl on the Stratus VOS
12 operating system. Perl is a scripting or macro language that is
13 popular on many systems. See L<perlbook> for a number of good
16 These are instructions for building Perl from source. Most people can
17 simply download a pre-compiled distribution from the VOS anonymous FTP
18 site. If you are running VOS Release 14.2.0 or earlier, download Perl
19 from ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html. If you are
20 running VOS Release 14.3.0 or later, download Perl from
21 ftp://ftp.stratus.com/pub/vos/posix/ga/ga.html. Instructions for
22 unbundling the Perl distribution file are at
23 ftp://ftp.stratus.com/pub/vos/utility/utility.html.
25 If you are running VOS Release 14.4.1 or later, you can obtain a
26 pre-compiled, supported copy of perl by purchasing Release 2.0.1
27 of the VOS GNU C++ and GNU Tools product from Stratus
30 =head2 Multiple methods to build perl for VOS
32 If you elect to build perl from its source code, you have several
33 different ways that you can build perl. The method that you use
34 depends on the version of VOS that you are using and on the
35 architecture of you Stratus hardware platform.
41 If you have a Stratus XA2000 (Motorola 68k-based) platform, you
42 must build perl using the alpha version of VOS POSIX support and
43 using the VOS Standard C Cross-compiler. You must build perl on
44 VOS Release 14.1.0 (or later) on an XA/R or Continuum platform.
46 This version of perl is properly called "miniperl" because it
47 does not contain the full perl functionality.
49 You must build perl with the compile_perl.cm command macro found
50 in the vos subdirectory.
54 If you have a Stratus XA/R (Intel i860-based) platform, you must
55 build perl using the alpha version of VOS POSIX support and using
56 the VOS Standard C compiler or cross-compiler. You must build
57 perl on VOS Release 14.1.0 (or later) on an XA/R or Continuum
60 This version of perl is properly called "miniperl" because it
61 does not contain the full perl functionality.
63 You must build perl with the compile_perl.cm command macro found
64 in the vos subdirectory.
68 If you have a Stratus Continuum (PARISC-based) platform that is
69 running a version of VOS earlier than VOS 14.3.0, you must build
70 perl using the alpha version of VOS POSIX support and using the
71 VOS Standard C compiler or cross-compiler. You must build perl
72 on VOS Release 14.1.0 (or later) on an XA/R or Continuum
75 This version of perl is properly called "miniperl" because it
76 does not contain the full perl functionality.
78 You must build perl with the compile_perl.cm command macro found
79 in the vos subdirectory.
83 If you have a Stratus Continuum (PARISC-based) platform that is
84 running VOS Release 14.3.0 through VOS Release 14.4.0, you must
85 build perl using the generally-available version of VOS POSIX
86 support, and using either the VOS Standard C compiler or the VOS
87 GNU C compiler. You must build perl on VOS Release 14.3.0 (or
88 later) on a Continuum platform.
90 This version of perl is properly called "miniperl" because it
91 does not contain the full perl functionality.
93 You must build perl with the compile_perl.cm command macro found
94 in the vos subdirectory.
98 If you have a Stratus Continuum (PA-RISC-based) platform that is
99 running VOS Release 14.4.1 or later, you must build perl using
100 the generally-available version of VOS POSIX support. You must
101 use the VOS GNU C compiler and the VOS GNU Tools product. You
102 must build perl on VOS Release 14.4.1 (or later) on a Continuum
105 This version of perl is properly called "full perl" because it
106 contains the full perl functionality.
108 You must use the supplied Configure script and makefiles to build
113 =head2 Stratus POSIX Support
115 Note that there are two different implementations of POSIX.1
116 support on VOS. There is an alpha version of POSIX that is
117 available from the Stratus anonymous ftp site
118 (ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html). There
119 is a generally-available version of POSIX that comes with VOS
120 Release 14.3.0 or higher. This port of POSIX will compile and
121 bind with either version of POSIX.
123 Most of the Perl features should work on VOS regardless of which
124 version of POSIX that you are using. However, the alpha version
125 of POSIX is missing a number of key functions, and therefore any
126 attempt by perl.pm to call the following unimplemented POSIX
127 functions will result in an error message and an immediate and
128 fatal call to the VOS debugger. They are "dup", "fork", and
129 "waitpid". The lack of these functions prevents you from
130 starting VOS commands and grabbing their output in perl. The
131 workaround is to run the commands outside of perl, then have perl
132 process the output file. These functions are all available in
133 the generally-available version of POSIX.
135 =head1 INSTALLING PERL IN VOS
137 =head2 Compiling Perl 5 on VOS
139 Before you can build Perl 5 on VOS, you need to have or acquire the
140 following additional items.
146 The VOS Standard C Compiler (or the VOS Standard C
147 Cross-Compiler) and the VOS C Runtime. If you are using
148 the generally-available version of POSIX support, you may
149 instead use the VOS GNU C/C++ Compiler. These are
150 standard Stratus products.
154 Either the VOS OS TCP/IP or STCP product set. If you are
155 building with the alpha version of POSIX you need the OS
156 TCP/IP product set. If you are building with the
157 generally-available version of POSIX you need the STCP
158 product set. These are standard Stratus products.
162 Either the alpha or generally-available version of the VOS
165 The alpha version of POSIX.1 support is available on the
166 Stratus FTP site. Login anonymously to ftp.stratus.com and
167 get the file /pub/vos/posix/alpha/posix.save.evf.gz in
168 binary file-transfer mode. Or use the Uniform Resource
170 ftp://ftp.stratus.com/pub/vos/posix/alpha/posix.save.evf.gz from
171 your web browser. Instructions for unbundling this file
172 are at ftp://ftp.stratus.com/pub/vos/utility/utility.html.
173 This is not a standard Stratus product.
175 In VOS Release 14.3.0, the generally-available version of
176 POSIX.1 support is bundled with the VOS Standard C compiler
177 (or Standard C Cross-Compiler). In VOS Release 14.4.0 or
178 higher, it is also bundled with the VOS C Runtime. These
179 are standard Stratus products.
183 You must compile this version of Perl 5 on VOS Release
184 14.1.0 or higher because some of the perl source files
185 contain more than 32,767 source lines. Due to VOS
186 release-compatibility rules, this port of perl may not
187 execute on VOS Release 12 or earlier.
191 If you are using the generally-available version of VOS POSIX
192 support, then you should also acquire the VOS GNU C/C++ Compiler
193 and GNU Tools product. When perl is built with this version of
194 POSIX support, it assumes that it can find "bash", "sed" and
195 other POSIX-compatible commands in the directory
196 /system/gnu_library/bin.
200 To build perl using the supplied VOS command macros, change to
201 the "vos" subdirectory and type the command "compile_perl
202 -processor X", where X is the processor type (mc68020, i80860,
203 pa7100, pa8000) that you wish to use. Note that the
204 generally-available version of POSIX.1 support is not available
205 for the mc68020 or i80860 processors.
207 Use the "-version alpha" control argument to build perl with
208 the alpha version of POSIX support, and use the "-version
209 ga" control argument to build it with the
210 generally-available version of POSIX. The default is "ga".
212 Use the "-compiler cc" control argument to build perl with
213 the VOS Standard C compiler. Use the "-compiler gcc"
214 control argument to build it with the GNU GCC compiler. The
217 You must have purchased the VOS Standard C Cross Compiler in
218 order to compile perl for a processor type that is different
219 from the processor type of the module.
221 Note that code compiled for the pa7100 processor type can
222 execute on the PA7100, PA8000, PA8500 and PA8600 processors, and
223 that code compiled for the pa8000 processor type can execute on
224 the PA8000, PA8500 and PA8600 processors.
226 To build perl using the supplied Configure script and makefiles,
227 execute the following commands.
229 !add_library_path command >system>gnu_library>bin -after '(current_dir)'
231 gzip -d perl-5.8.0.tar.gz
232 tar -xvf perl-5.8.0.tar
237 If you wish to run the test cases, type:
241 =head2 Installing Perl 5 on VOS
247 If you have built perl using the Configure script, ensure that
248 you have modify permission to >system>ported and type
254 If you have built perl using any of the other methods, type
256 install_perl -processor PROCESSOR -name NAME
258 where PROCESSOR is mc68020, i80860, pa7100, or pa8000, as
259 appropriate, and NAME is perl or perl5, according to which name
262 This command macro will install perl and all of its related
263 files in the proper directories.
267 While there are currently no architecture-specific
268 extensions or modules distributed with perl, the following
269 directories can be used to hold such files:
271 >system>ported>lib>perl5>5.8.0>68k
272 >system>ported>lib>perl5>5.8.0>860
273 >system>ported>lib>perl5>5.8.0>7100
274 >system>ported>lib>perl5>5.8.0>8000
278 Site-specific perl extensions and modules can be installed in one of
279 two places. Put architecture-independent files into:
281 >system>ported>lib>perl5>site_perl>5.8.0
283 Put site-specific architecture-dependent files into one of the
284 following directories:
286 >system>ported>lib>perl5>site_perl>5.8.0>68k
287 >system>ported>lib>perl5>site_perl>5.8.0>860
288 >system>ported>lib>perl5>site_perl>5.8.0>7100
289 >system>ported>lib>perl5>site_perl>5.8.0>8000
293 You can examine the @INC variable from within a perl program
294 to see the order in which Perl searches these directories.
298 =head1 USING PERL IN VOS
300 =head2 Unimplemented Features of Perl on VOS
302 If perl is built with the alpha version of VOS POSIX.1 support
303 and if it attempts to call an unimplemented VOS POSIX.1
304 function, it will print a fatal error message and enter the VOS
305 debugger. This error is not recoverable. See vos_dummies.c for
306 a list of the unimplemented POSIX.1 functions. To see what
307 functions are unimplemented and what the error message looks
308 like, compile and execute "test_vos_dummies.c".
310 =head2 Restrictions of Perl on VOS
312 This port of Perl version 5 to VOS prefers Unix-style,
313 slash-separated pathnames over VOS-style greater-than-separated
314 pathnames. VOS-style pathnames should work in most contexts, but
315 if you have trouble, replace all greater-than characters by slash
316 characters. Because the slash character is used as a pathname
317 delimiter, Perl cannot process VOS pathnames containing a slash
318 character in a directory or file name; these must be renamed.
320 This port of Perl also uses Unix-epoch date values internally.
321 As long as you are dealing with ASCII character string
322 representations of dates, this should not be an issue. The
323 supported epoch is January 1, 1980 to January 17, 2038.
325 See the file pod/perlport.pod for more information about the VOS
328 =head1 SUPPORT STATUS
330 I'm offering this port "as is". You can ask me questions, but I
331 can't guarantee I'll be able to answer them. There are some
332 excellent books available on the Perl language; consult a book
335 If you want a supported version of perl for VOS, purchase the VOS
336 GNU C++ and GNU Tools Release 2.0.1 product from Stratus
337 Technologies, along with a support contract (or from anyone else
338 who will sell you support).
