| 135 | .SH "SYNOPSIS" |
| 136 | .IX Header "SYNOPSIS" |
| 137 | This file contains notes for building perl on the Stratus \s-1VOS\s0 |
| 138 | operating system. Perl is a scripting or macro language that is |
| 139 | popular on many systems. See perlbook for a number of good |
| 140 | books on Perl. |
| 141 | .PP |
| 142 | These are instructions for building Perl from source. Most people can |
| 143 | simply download a pre-compiled distribution from the \s-1VOS\s0 anonymous \s-1FTP\s0 |
| 144 | site. If you are running \s-1VOS\s0 Release 14.2.0 or earlier, download Perl |
| 145 | from ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html If you are |
| 146 | running \s-1VOS\s0 Release 14.3.0 or later, download Perl from |
| 147 | ftp://ftp.stratus.com/pub/vos/posix/ga/ga.html Instructions for |
| 148 | unbundling the Perl distribution file are at |
| 149 | ftp://ftp.stratus.com/pub/vos/utility/utility.html |
| 150 | .PP |
| 151 | If you are running \s-1VOS\s0 Release 14.4.1 or later, you can obtain a |
| 152 | pre\-compiled, supported copy of perl by purchasing Release 2.0.1 |
| 153 | (or later) of the \s-1VOS\s0 \s-1GNU\s0 \*(C+ and \s-1GNU\s0 Tools product from Stratus |
| 154 | Technologies. |
| 155 | .Sh "Multiple methods to build perl for \s-1VOS\s0" |
| 156 | .IX Subsection "Multiple methods to build perl for VOS" |
| 157 | If you elect to build perl from its source code, you have several |
| 158 | different ways that you can build perl. The method that you use |
| 159 | depends on the version of \s-1VOS\s0 that you are using and on the |
| 160 | architecture of your Stratus hardware platform. |
| 161 | .IP "1" 5 |
| 162 | .IX Item "1" |
| 163 | If you have a Stratus \s-1XA2000\s0 (Motorola 68k\-based) platform, you |
| 164 | must build perl using the alpha version of \s-1VOS\s0 \s-1POSIX\s0 support and |
| 165 | using the \s-1VOS\s0 Standard C Cross\-compiler. You must build perl on |
| 166 | \&\s-1VOS\s0 Release 14.1.0 (or later) on an \s-1XA/R\s0 or Continuum platform. |
| 167 | .Sp |
| 168 | This version of perl is properly called \*(L"miniperl\*(R" because it |
| 169 | does not contain the complete perl functionality. |
| 170 | .Sp |
| 171 | You must build perl with the compile_perl.cm command macro found |
| 172 | in the vos subdirectory. |
| 173 | .IP "2" 5 |
| 174 | .IX Item "2" |
| 175 | If you have a Stratus \s-1XA/R\s0 (Intel i860\-based) platform, you must |
| 176 | build perl using the alpha version of \s-1VOS\s0 \s-1POSIX\s0 support and using |
| 177 | the \s-1VOS\s0 Standard C compiler or cross\-compiler. You must build |
| 178 | perl on \s-1VOS\s0 Release 14.1.0 (or later) on an \s-1XA/R\s0 or Continuum |
| 179 | platform. |
| 180 | .Sp |
| 181 | This version of perl is properly called \*(L"miniperl\*(R" because it |
| 182 | does not contain the complete perl functionality. |
| 183 | .Sp |
| 184 | You must build perl with the compile_perl.cm command macro found |
| 185 | in the vos subdirectory. |
| 186 | .IP "3" 5 |
| 187 | .IX Item "3" |
| 188 | If you have a Stratus Continuum (PA\-RISC\-based) platform that is |
| 189 | running a version of \s-1VOS\s0 earlier than \s-1VOS\s0 14.3.0, you must build |
| 190 | perl using the alpha version of \s-1VOS\s0 \s-1POSIX\s0 support and using the |
| 191 | \&\s-1VOS\s0 Standard C compiler or cross\-compiler. You must build perl |
| 192 | on \s-1VOS\s0 Release 14.1.0 (or later) on an \s-1XA/R\s0 or Continuum |
| 193 | platform. |
| 194 | .Sp |
| 195 | This version of perl is properly called \*(L"miniperl\*(R" because it |
| 196 | does not contain the complete perl functionality. |
| 197 | .Sp |
| 198 | You must build perl with the compile_perl.cm command macro found |
| 199 | in the vos subdirectory. |
| 200 | .IP "4" 5 |
| 201 | .IX Item "4" |
| 202 | If you have a Stratus Continuum (PA\-RISC\-based) platform that is |
| 203 | running \s-1VOS\s0 Release 14.3.0 through \s-1VOS\s0 Release 14.4.1, you must |
| 204 | build perl using the generally-available version of \s-1VOS\s0 \s-1POSIX\s0 |
| 205 | support, and using either the \s-1VOS\s0 Standard C compiler or the \s-1VOS\s0 |
| 206 | \&\s-1GNU\s0 C compiler. You must build perl on \s-1VOS\s0 Release 14.3.0 (or |
| 207 | later) on a Continuum platform. |
| 208 | .Sp |
| 209 | This version of perl is properly called \*(L"miniperl\*(R" because it |
| 210 | does not contain the complete perl functionality. |
| 211 | .Sp |
| 212 | You must build perl with the compile_perl.cm command macro found |
| 213 | in the vos subdirectory. |
| 214 | .IP "5" 5 |
| 215 | .IX Item "5" |
| 216 | If you have a Stratus Continuum (PA\-RISC\-based) platform that is |
| 217 | running \s-1VOS\s0 Release 14.5.0 or later, you can either use the |
| 218 | previous method to build \*(L"miniperl\*(R" or you can build \*(L"full |
| 219 | perl\*(R", which contains the complete functionality of perl. I |
| 220 | strongly recommend that you build full perl. To build full |
| 221 | perl, you must use the generally-available version of \s-1VOS\s0 \s-1POSIX\s0 |
| 222 | support. You must use the \s-1VOS\s0 \s-1GNU\s0 C compiler and the \s-1VOS\s0 \s-1GNU\s0 |
| 223 | C/\*(C+ and \s-1GNU\s0 Tools Release 2.0.1 (or later) product. You must |
| 224 | build full perl on \s-1VOS\s0 Release 14.5.0 (or later) on a Continuum |
| 225 | platform. |
| 226 | .Sp |
| 227 | You must build full perl with the compile_full_perl.cm command |
| 228 | macro found in the vos subdirectory. |
| 229 | .Sh "Stratus \s-1POSIX\s0 Support" |
| 230 | .IX Subsection "Stratus POSIX Support" |
| 231 | Note that there are two different implementations of \s-1POSIX\s0.1 |
| 232 | support on \s-1VOS\s0. There is an alpha version of \s-1POSIX\s0 that is |
| 233 | available from the Stratus anonymous ftp site |
| 234 | ( ftp://ftp.stratus.com/pub/vos/posix/alpha/alpha.html ). There |
| 235 | is a generally-available version of \s-1POSIX\s0 that comes with \s-1VOS\s0 |
| 236 | Release 14.3.0 or higher. This port of \s-1POSIX\s0 will compile and |
| 237 | bind with either version of \s-1POSIX\s0. |
| 238 | .PP |
| 239 | Most of the Perl features should work on \s-1VOS\s0 regardless of which |
| 240 | version of \s-1POSIX\s0 that you are using. However, the alpha version |
| 241 | of \s-1POSIX\s0 is missing a number of key functions, and therefore any |
| 242 | attempt by perl.pm to call the following unimplemented \s-1POSIX\s0 |
| 243 | functions will result in an error message and an immediate and |
| 244 | fatal call to the \s-1VOS\s0 debugger. They are \*(L"dup\*(R", \*(L"fork\*(R", and |
| 245 | \&\*(L"waitpid\*(R". The lack of these functions prevents you from |
| 246 | starting \s-1VOS\s0 commands and grabbing their output in perl. The |
| 247 | workaround is to run the commands outside of perl, then have perl |
| 248 | process the output file. These functions are all available in |
| 249 | the generally-available version of \s-1POSIX\s0. |

| 253 | .IX Subsection "Compiling Perl 5 on VOS" |
| 254 | Before you can build Perl 5 on \s-1VOS\s0, you need to have or acquire the |
| 255 | following additional items. |
| 256 | .IP "1" 5 |
| 257 | .IX Item "1" |
| 258 | The \s-1VOS\s0 Standard C Compiler (or the \s-1VOS\s0 Standard C |
| 259 | Cross\-Compiler) and the \s-1VOS\s0 C Runtime. If you are using |
| 260 | the generally-available version of \s-1POSIX\s0 support, you may |
| 261 | instead use the \s-1VOS\s0 \s-1GNU\s0 C/\*(C+ Compiler. These are |
| 262 | standard Stratus products. |
| 263 | .IP "2" 5 |
| 264 | .IX Item "2" |
| 265 | Either the \s-1VOS\s0 \s-1OS\s0 \s-1TCP/IP\s0 or \s-1STCP\s0 product set. If you are |
| 266 | building with the alpha version of \s-1POSIX\s0 you need the \s-1OS\s0 |
| 267 | \&\s-1TCP/IP\s0 product set. If you are building with the |
| 268 | generally-available version of \s-1POSIX\s0 you need the \s-1STCP\s0 |
| 269 | product set. These are standard Stratus products. |
| 270 | .IP "3" 5 |
| 271 | .IX Item "3" |
| 272 | Either the alpha or generally-available version of the \s-1VOS\s0 |
| 273 | \&\s-1POSIX\s0.1 environment. |
| 274 | .Sp |
| 275 | The alpha version of \s-1POSIX\s0.1 support is available on the |
| 276 | Stratus \s-1FTP\s0 site. Login anonymously to ftp.stratus.com and |
| 277 | get the file /pub/vos/posix/alpha/posix.save.evf.gz in |
| 278 | binary file-transfer mode. Or use the Uniform Resource |
| 279 | Locator (\s-1URL\s0) |
| 280 | ftp://ftp.stratus.com/pub/vos/posix/alpha/posix.save.evf.gz from |
| 281 | your web browser. Instructions for unbundling this file |
| 282 | are at ftp://ftp.stratus.com/pub/vos/utility/utility.html |
| 283 | This is \s-1NOT\s0 a standard Stratus product. |
| 284 | .Sp |
| 285 | In \s-1VOS\s0 Release 14.3.0, the generally-available version of |
| 286 | \&\s-1POSIX\s0.1 support is bundled with the \s-1VOS\s0 Standard C compiler |
| 287 | (or Standard C Cross\-Compiler). In \s-1VOS\s0 Release 14.4.0 or |
| 288 | higher, it is also bundled with the \s-1VOS\s0 C Runtime. These |
| 289 | are standard Stratus products. |
| 290 | .IP "4" 5 |
| 291 | .IX Item "4" |
| 292 | You must compile this version of Perl 5 on \s-1VOS\s0 Release |
| 293 | 14.1.0 or higher because some of the perl source files |
| 294 | contain more than 32,767 source lines. Due to \s-1VOS\s0 |
| 295 | release-compatibility rules, this port of perl may not |
| 296 | execute on \s-1VOS\s0 Release 12 or earlier. |
| 297 | .IP "5" 5 |
| 298 | .IX Item "5" |
| 299 | If you are using the generally-available version of \s-1VOS\s0 \s-1POSIX\s0 |
| 300 | support, then you should also acquire the \s-1VOS\s0 \s-1GNU\s0 C/\*(C+ Compiler |
| 301 | and \s-1GNU\s0 Tools product. When perl is built with this version of |
| 302 | \&\s-1POSIX\s0 support, it assumes that it can find \*(L"bash\*(R", \*(L"sed\*(R" and |
| 303 | other POSIX-compatible commands in the directory |
| 304 | /system/gnu_library/bin. |
| 305 | .PP |
| 306 | To build perl using the supplied \s-1VOS\s0 command macros, change to |
| 307 | the \*(L"vos\*(R" subdirectory and type the command \*(L"compile_perl |
| 308 | \&\-processor X\*(R", where X is the processor type (mc68020, i80860, |
| 309 | pa7100, pa8000) that you wish to use. Note that the |
| 310 | generally-available version of \s-1POSIX\s0.1 support is not available |
| 311 | for the mc68020 or i80860 processors. |
| 312 | .PP |
| 313 | Use the \*(L"\-version alpha\*(R" control argument to build perl with |
| 314 | the alpha version of \s-1POSIX\s0 support, and use the \*(L"\-version |
| 315 | ga\*(R" control argument to build it with the |
| 316 | generally-available version of \s-1POSIX\s0. The default is \*(L"ga\*(R". |
| 317 | .PP |
| 318 | Use the \*(L"\-compiler cc\*(R" control argument to build perl with |
| 319 | the \s-1VOS\s0 Standard C compiler. Use the \*(L"\-compiler gcc\*(R" |
| 320 | control argument to build it with the \s-1GNU\s0 \s-1GCC\s0 compiler. The |
| 321 | default is \*(L"cc\*(R". |
| 322 | .PP |
| 323 | You must have purchased the \s-1VOS\s0 Standard C Cross Compiler in |
| 324 | order to compile perl for a processor type that is different |
| 325 | from the processor type of the module. |
| 326 | .PP |
| 327 | Note that code compiled for the pa7100 processor type can |
| 328 | execute on the \s-1PA7100\s0, \s-1PA8000\s0, \s-1PA8500\s0 and \s-1PA8600\s0 processors, and |
| 329 | that code compiled for the pa8000 processor type can execute on |

| 397 | .IX Subsection "Unimplemented Features of Perl on VOS" |
| 398 | If perl is built with the alpha version of \s-1VOS\s0 \s-1POSIX\s0.1 support |
| 399 | and if it attempts to call an unimplemented \s-1VOS\s0 \s-1POSIX\s0.1 |
| 400 | function, it will print a fatal error message and enter the \s-1VOS\s0 |
| 401 | debugger. This error is not recoverable. See vos_dummies.c for |
| 402 | a list of the unimplemented \s-1POSIX\s0.1 functions. To see what |
| 403 | functions are unimplemented and what the error message looks |
| 404 | like, compile and execute \*(L"test_vos_dummies.c\*(R". |
| 405 | .Sh "Restrictions of Perl on \s-1VOS\s0" |
| 406 | .IX Subsection "Restrictions of Perl on VOS" |
| 407 | This port of Perl version 5 to \s-1VOS\s0 prefers Unix\-style, |
| 408 | slash-separated pathnames over VOS-style greater-than-separated |
| 409 | pathnames. VOS-style pathnames should work in most contexts, but |
| 410 | if you have trouble, replace all greater-than characters by slash |
| 411 | characters. Because the slash character is used as a pathname |
| 412 | delimiter, Perl cannot process \s-1VOS\s0 pathnames containing a slash |
| 413 | character in a directory or file name; these must be renamed. |
| 414 | .PP |
| 415 | This port of Perl also uses Unix-epoch date values internally. |
| 416 | As long as you are dealing with \s-1ASCII\s0 character string |
| 417 | representations of dates, this should not be an issue. The |
| 418 | supported epoch is January 1, 1980 to January 17, 2038. |

| 422 | .Sh "Handling of underflow and overflow" |
| 423 | .IX Subsection "Handling of underflow and overflow" |
| 424 | Prior to \s-1VOS\s0 Release 14.7.0, \s-1VOS\s0 does not support automatically |
| 425 | mapping overflowed floating-point values to +infinity, nor |
| 426 | automatically mapping underflowed floating-point values to zero, |
| 427 | unlike many other platforms. The Perl pack function has been |
| 428 | modified to perform such mapping in software on \s-1VOS\s0. Performing |
| 429 | other floating-point computations that underflow or overflow |
| 430 | will probably result in \s-1SIGFPE\s0. Don't push your luck. |
| 431 | .PP |
| 432 | As of \s-1VOS\s0 Release 14.7.0, the \s-1VOS\s0 \s-1POSIX\s0 runtime sets up the |
| 433 | PA-RISC hardware floating-point status register so that the |
| 434 | overflow and underflow exceptions do not trap, but instead |
| 435 | automatically convert the result to infinity or zero, as |
| 436 | appropriate. As of this writing, there are still floating-point |
| 437 | operations that can trap, for example, subtracting two infinite |
| 438 | values. This is recorded as suggestion posix\-1022, which is not |
| 439 | yet fixed. |
