| 134 | README.os390 \- building and installing Perl for OS/390 and z/OS |
| 135 | .SH "SYNOPSIS" |
| 136 | .IX Header "SYNOPSIS" |
| 137 | This document will help you Configure, build, test and install Perl |
| 138 | on \s-1OS/390\s0 (aka z/OS) Unix System Services. |
| 139 | .SH "DESCRIPTION" |
| 140 | .IX Header "DESCRIPTION" |
| 141 | This is a fully ported Perl for \s-1OS/390\s0 Version 2 Release 3, 5, 6, 7, |
| 142 | 8, and 9. It may work on other versions or releases, but those are |
| 143 | the ones we've tested it on. |
| 144 | .PP |
| 145 | You may need to carry out some system configuration tasks before |
| 146 | running the Configure script for Perl. |
| 147 | .Sh "Tools" |
| 148 | .IX Subsection "Tools" |
| 149 | The z/OS Unix Tools and Toys list may prove helpful and contains links |
| 150 | to ports of much of the software helpful for building Perl. |

| 152 | .Sh "Unpacking Perl distribution on \s-1OS/390\s0" |
| 153 | .IX Subsection "Unpacking Perl distribution on OS/390" |
| 154 | If using ftp remember to transfer the distribution in binary format. |
| 155 | .PP |
| 156 | Gunzip/gzip for \s-1OS/390\s0 is discussed at: |
| 157 | .PP |
| 158 | .Vb 1 |
| 159 | \& http://www-1.ibm.com/servers/eserver/zseries/zos/unix/faq/bpxqp1.html |
| 160 | .Ve |
| 161 | .PP |
| 162 | to extract an \s-1ASCII\s0 tar archive on \s-1OS/390\s0, try this: |
| 163 | .PP |
| 164 | .Vb 1 |
| 165 | \& pax -o to=IBM-1047,from=ISO8859-1 -r < latest.tar |
| 166 | .Ve |
| 167 | .PP |
| 168 | or |
| 169 | .PP |
| 170 | .Vb 1 |
| 171 | \& zcat latest.tar.Z | pax -o to=IBM-1047,from=ISO8859-1 -r |
| 172 | .Ve |
| 173 | .PP |
| 174 | If you get lots of errors of the form |
| 175 | .PP |
| 176 | .Vb 1 |
| 177 | \& tar: FSUM7171 ...: cannot set uid/gid: EDC5139I Operation not permitted. |
| 178 | .Ve |
| 179 | .PP |
| 180 | you didn't read the above and tried to use tar instead of pax, you'll |
| 181 | first have to remove the (now corrupt) perl directory |
| 182 | .PP |
| 183 | .Vb 1 |
| 184 | \& rm -rf perl-... |
| 185 | .Ve |
| 186 | .PP |
| 187 | and then use pax. |
| 188 | .Sh "Setup and utilities for Perl on \s-1OS/390\s0" |
| 189 | .IX Subsection "Setup and utilities for Perl on OS/390" |
| 190 | Be sure that your yacc installation is in place including any necessary |
| 191 | parser template files. If you have not already done so then be sure to: |
| 192 | .PP |
| 193 | .Vb 1 |
| 194 | \& cp /samples/yyparse.c /etc |
| 195 | .Ve |
| 196 | .PP |
| 197 | This may also be a good time to ensure that your /etc/protocol file |
| 198 | and either your /etc/resolv.conf or /etc/hosts files are in place. |
| 199 | The \s-1IBM\s0 document that described such \s-1USS\s0 system setup issues was |
| 200 | \&\s-1SC28\-1890\-07\s0 \*(L"\s-1OS/390\s0 \s-1UNIX\s0 System Services Planning\*(R", in particular |
| 201 | Chapter 6 on customizing the \s-1OE\s0 shell. |
| 202 | .PP |
| 203 | \&\s-1GNU\s0 make for \s-1OS/390\s0, which is recommended for the build of perl (as |
| 204 | well as building \s-1CPAN\s0 modules and extensions), is available from the |
| 205 | \&\*(L"Tools\*(R". |
| 206 | .PP |
| 207 | Some people have reported encountering \*(L"Out of memory!\*(R" errors while |
| 208 | trying to build Perl using \s-1GNU\s0 make binaries. If you encounter such |
| 209 | trouble then try to download the source code kit and build \s-1GNU\s0 make |
| 210 | from source to eliminate any such trouble. You might also find \s-1GNU\s0 make |
| 211 | (as well as Perl and Apache) in the red\-piece/book \*(L"Open Source Software |
| 212 | for \s-1OS/390\s0 \s-1UNIX\s0\*(R", \s-1SG24\-5944\-00\s0 from \s-1IBM\s0. |
| 213 | .PP |
| 214 | If instead of the recommended \s-1GNU\s0 make you would like to use the system |
| 215 | supplied make program then be sure to install the default rules file |
| 216 | properly via the shell command: |
| 217 | .PP |
| 218 | .Vb 1 |
| 219 | \& cp /samples/startup.mk /etc |
| 220 | .Ve |
| 221 | .PP |
| 222 | and be sure to also set the environment variable _C89_CCMODE=1 (exporting |
| 223 | _C89_CCMODE=1 is also a good idea for users of \s-1GNU\s0 make). |
| 224 | .PP |
| 225 | You might also want to have \s-1GNU\s0 groff for \s-1OS/390\s0 installed before |
| 226 | running the \*(L"make install\*(R" step for Perl. |
| 227 | .PP |
| 228 | There is a syntax error in the /usr/include/sys/socket.h header file |
| 229 | that \s-1IBM\s0 supplies with \s-1USS\s0 V2R7, V2R8, and possibly V2R9. The problem with |
| 230 | the header file is that near the definition of the \s-1SO_REUSEPORT\s0 constant |
| 231 | there is a spurious extra '/' character outside of a comment like so: |
| 232 | .PP |
| 233 | .Vb 2 |
| 234 | \& #define SO_REUSEPORT 0x0200 /* allow local address & port |
| 235 | \& reuse */ / |
| 236 | .Ve |
| 237 | .PP |
| 238 | You could edit that header yourself to remove that last '/', or you might |
| 239 | note that Language Environment (\s-1LE\s0) \s-1APAR\s0 \s-1PQ39997\s0 describes the problem |
| 240 | and \s-1PTF\s0's \s-1UQ46272\s0 and \s-1UQ46271\s0 are the (R8 at least) fixes and apply them. |
| 241 | If left unattended that syntax error will turn up as an inability for Perl |
| 242 | to build its \*(L"Socket\*(R" extension. |
| 243 | .PP |
| 244 | For successful testing you may need to turn on the sticky bit for your |
| 245 | world readable /tmp directory if you have not already done so (see man chmod). |
| 246 | .Sh "Configure Perl on \s-1OS/390\s0" |
| 247 | .IX Subsection "Configure Perl on OS/390" |
| 248 | Once you've unpacked the distribution, run \*(L"sh Configure\*(R" (see \s-1INSTALL\s0 |
| 249 | for a full discussion of the Configure options). There is a \*(L"hints\*(R" file |
| 250 | for os390 that specifies the correct values for most things. Some things |
| 251 | to watch out for include: |
| 252 | .IP "\(bu" 4 |
| 253 | A message of the form: |
| 254 | .Sp |
| 255 | .Vb 2 |
| 256 | \& (I see you are using the Korn shell. Some ksh's blow up on Configure, |
| 257 | \& mainly on older exotic systems. If yours does, try the Bourne shell instead.) |
| 258 | .Ve |
| 259 | .Sp |
| 260 | is nothing to worry about at all. |
| 261 | .IP "\(bu" 4 |
| 262 | Some of the parser default template files in /samples are needed in /etc. |
| 263 | In particular be sure that you at least copy /samples/yyparse.c to /etc |
| 264 | before running Perl's Configure. This step ensures successful extraction |
| 265 | of \s-1EBCDIC\s0 versions of parser files such as perly.c, perly.h, and x2p/a2p.c. |
| 266 | This has to be done before running Configure the first time. If you failed |
| 267 | to do so then the easiest way to re-Configure Perl is to delete your |
| 268 | misconfigured build root and re-extract the source from the tar ball. |
| 269 | Then you must ensure that /etc/yyparse.c is properly in place before |
| 270 | attempting to re-run Configure. |
| 271 | .IP "\(bu" 4 |
| 272 | This port will support dynamic loading, but it is not selected by |
| 273 | default. If you would like to experiment with dynamic loading then |
| 274 | be sure to specify \-Dusedl in the arguments to the Configure script. |
| 275 | See the comments in hints/os390.sh for more information on dynamic loading. |
| 276 | If you build with dynamic loading then you will need to add the |
| 277 | \&\f(CW$archlibexp\fR/CORE directory to your \s-1LIBPATH\s0 environment variable in order |
| 278 | for perl to work. See the config.sh file for the value of \f(CW$archlibexp\fR. |
| 279 | If in trying to use Perl you see an error message similar to: |
| 280 | .Sp |
| 281 | .Vb 2 |
| 282 | \& CEE3501S The module libperl.dll was not found. |
| 283 | \& From entry point __dllstaticinit at compile unit offset +00000194 at |
| 284 | .Ve |
| 285 | .Sp |
| 286 | then your \s-1LIBPATH\s0 does not have the location of libperl.x and either |
| 287 | libperl.dll or libperl.so in it. Add that directory to your \s-1LIBPATH\s0 and |
| 288 | proceed. |
| 289 | .IP "\(bu" 4 |
| 290 | Do not turn on the compiler optimization flag \*(L"\-O\*(R". There is |
| 291 | a bug in either the optimizer or perl that causes perl to |
| 292 | not work correctly when the optimizer is on. |
| 293 | .IP "\(bu" 4 |
| 294 | Some of the configuration files in /etc used by the |
| 295 | networking APIs are either missing or have the wrong |
| 296 | names. In particular, make sure that there's either |
| 297 | an /etc/resolv.conf or an /etc/hosts, so that |
| 298 | \&\fIgethostbyname()\fR works, and make sure that the file |
| 299 | /etc/proto has been renamed to /etc/protocol (\s-1NOT\s0 |
| 300 | /etc/protocols, as used by other Unix systems). |
| 301 | You may have to look for things like \s-1HOSTNAME\s0 and \s-1DOMAINORIGIN\s0 |
| 302 | in the \*(L"//'\s-1SYS1\s0.TCPPARMS(\s-1TCPDATA\s0)'\*(R" \s-1PDS\s0 member in order to |
| 303 | properly set up your /etc networking files. |

| 310 | \& make |
| 311 | \& make test |
| 312 | .Ve |

| 316 | .Vb 1 |
| 317 | \& make install |
| 318 | .Ve |
| 319 | .PP |
| 320 | this last step may or may not require UID=0 privileges depending |
| 321 | on how you answered the questions that Configure asked and whether |
| 322 | or not you have write access to the directories you specified. |
| 323 | .Sh "Build Anomalies with Perl on \s-1OS/390\s0" |
| 324 | .IX Subsection "Build Anomalies with Perl on OS/390" |
| 325 | \&\*(L"Out of memory!\*(R" messages during the build of Perl are most often fixed |
| 326 | by re building the \s-1GNU\s0 make utility for \s-1OS/390\s0 from a source code kit. |
| 327 | .PP |
| 328 | Another memory limiting item to check is your \s-1MAXASSIZE\s0 parameter in your |
| 329 | \&'\s-1SYS1\s0.PARMLIB(BPXPRMxx)' data set (note too that as of V2R8 address space |
| 330 | limits can be set on a per user \s-1ID\s0 basis in the \s-1USS\s0 segment of a \s-1RACF\s0 |
| 331 | profile). People have reported successful builds of Perl with \s-1MAXASSIZE\s0 |
| 332 | parameters as small as 503316480 (and it may be possible to build Perl |
| 333 | with a \s-1MAXASSIZE\s0 smaller than that). |
| 334 | .PP |
| 335 | Within \s-1USS\s0 your /etc/profile or \f(CW$HOME\fR/.profile may limit your ulimit |
| 336 | settings. Check that the following command returns reasonable values: |
| 337 | .PP |
| 338 | .Vb 1 |
| 339 | \& ulimit -a |
| 340 | .Ve |
| 341 | .PP |
| 342 | To conserve memory you should have your compiler modules loaded into the |
| 343 | Link Pack Area (\s-1LPA/ELPA\s0) rather than in a link list or step lib. |
| 344 | .PP |
| 345 | If the c89 compiler complains of syntax errors during the build of the |

| 400 | Out of Memory! |
| 401 | .Sp |
| 402 | Recent perl test suite is quite memory hunrgy. In addition to the comments |
| 403 | above on memory limitations it is also worth checking for _CEE_RUNOPTS |
| 404 | in your environment. Perl now has (in miniperlmain.c) a C #pragma |
| 405 | to set \s-1CEE\s0 run options, but the environment variable wins. |
| 406 | .Sp |
| 407 | The C code asks for: |
| 408 | .Sp |
| 409 | .Vb 1 |
| 410 | \& #pragma runopts(HEAP(2M,500K,ANYWHERE,KEEP,8K,4K) STACK(,,ANY,) ALL31(ON)) |
| 411 | .Ve |
| 412 | .Sp |
| 413 | The important parts of that are the second argument (the increment) to \s-1HEAP\s0, |
| 414 | and allowing the stack to be \*(L"Above the (16M) line\*(R". If the heap |
| 415 | increment is too small then when perl (for example loading unicode/Name.pl) tries |
| 416 | to create a \*(L"big\*(R" (400K+) string it cannot fit in a single segment |
| 417 | and you get \*(L"Out of Memory!\*(R" \- even if there is still plenty of memory |
| 418 | available. |
| 419 | .Sp |
| 420 | A related issue is use with perl's malloc. Perl's malloc uses \f(CW\*(C`sbrk()\*(C'\fR |
| 421 | to get memory, and \f(CW\*(C`sbrk()\*(C'\fR is limited to the first allocation so in this |
| 422 | case something like: |
| 423 | .Sp |
| 424 | .Vb 1 |
| 425 | \& HEAP(8M,500K,ANYWHERE,KEEP,8K,4K) |
| 426 | .Ve |
| 427 | .Sp |
| 428 | is needed to get through the test suite. |

| 436 | When using perl on \s-1OS/390\s0 please keep in mind that the \s-1EBCDIC\s0 and \s-1ASCII\s0 |
| 437 | character sets are different. See perlebcdic.pod for more on such character |
| 438 | set issues. Perl builtin functions that may behave differently under |

| 441 | Open Edition (\s-1UNIX\s0 System Services) from V2R8 onward does support |
| 442 | #!/path/to/perl script invocation. There is a \s-1PTF\s0 available from |
| 443 | \&\s-1IBM\s0 for V2R7 that will allow shell/kernel support for #!. \s-1USS\s0 |
| 444 | releases prior to V2R7 did not support the #! means of script invocation. |

| 447 | .Vb 1 |
| 448 | \& head `whence perldoc` |

| 452 | have Perl run your scripts on those older releases of Unix System Services. |
| 453 | .PP |
| 454 | If you are having trouble with square brackets then consider switching your |
| 455 | rlogin or telnet client. Try to avoid older 3270 emulators and \s-1ISHELL\s0 for |
| 456 | working with Perl on \s-1USS\s0. |
| 457 | .Sh "Floating Point Anomalies with Perl on \s-1OS/390\s0" |
| 458 | .IX Subsection "Floating Point Anomalies with Perl on OS/390" |
| 459 | There appears to be a bug in the floating point implementation on S/390 |
| 460 | systems such that calling \fIint()\fR on the product of a number and a small |
| 461 | magnitude number is not the same as calling \fIint()\fR on the quotient of |
| 462 | that number and a large magnitude number. For example, in the following |
| 463 | Perl code: |
| 464 | .PP |
| 465 | .Vb 4 |
| 466 | \& my $x = 100000.0; |
| 467 | \& my $y = int($x * 1e-5) * 1e5; # '0' |
| 468 | \& my $z = int($x / 1e+5) * 1e5; # '100000' |
| 469 | \& print "\e$y is $y and \e$z is $z\en"; # $y is 0 and $z is 100000 |
| 470 | .Ve |
| 471 | .PP |
| 472 | Although one would expect the quantities \f(CW$y\fR and \f(CW$z\fR to be the same and equal |
| 473 | to 100000 they will differ and instead will be 0 and 100000 respectively. |
| 474 | .PP |
| 475 | The problem can be further examined in a roughly equivalent C program: |
| 476 | .PP |
| 477 | .Vb 15 |
| 478 | \& #include <stdio.h> |
| 479 | \& #include <math.h> |
| 480 | \& main() |
| 481 | \& { |
| 482 | \& double r1,r2; |
| 483 | \& double x = 100000.0; |
| 484 | \& double y = 0.0; |
| 485 | \& double z = 0.0; |
| 486 | \& x = 100000.0 * 1e-5; |
| 487 | \& r1 = modf (x,&y); |
| 488 | \& x = 100000.0 / 1e+5; |
| 489 | \& r2 = modf (x,&z); |
| 490 | \& printf("y is %e and z is %e\en",y*1e5,z*1e5); |
| 491 | \& /* y is 0.000000e+00 and z is 1.000000e+05 (with c89) */ |
| 492 | \& } |

| 495 | .IX Subsection "Modules and Extensions for Perl on OS/390" |
| 496 | Pure pure (that is non xs) modules may be installed via the usual: |
| 497 | .PP |
| 498 | .Vb 4 |
| 499 | \& perl Makefile.PL |
| 500 | \& make |
| 501 | \& make test |
| 502 | \& make install |
| 503 | .Ve |
| 504 | .PP |
| 505 | If you built perl with dynamic loading capability then that would also |
| 506 | be the way to build xs based extensions. However, if you built perl with |
| 507 | the default static linking you can still build xs based extensions for \s-1OS/390\s0 |
| 508 | but you will need to follow the instructions in ExtUtils::MakeMaker for |
| 509 | building statically linked perl binaries. In the simplest configurations |
| 510 | building a static perl + xs extension boils down to: |
| 511 | .PP |
| 512 | .Vb 6 |
| 513 | \& perl Makefile.PL |
| 514 | \& make |
| 515 | \& make perl |
| 516 | \& make test |
| 517 | \& make install |
| 518 | \& make -f Makefile.aperl inst_perl MAP_TARGET=perl |
| 519 | .Ve |
| 520 | .PP |
| 521 | In most cases people have reported better results with \s-1GNU\s0 make rather |
| 522 | than the system's /bin/make program, whether for plain modules or for |
| 523 | xs based extensions. |
| 524 | .PP |
| 525 | If the make process encounters trouble with either compilation or |
| 526 | linking then try setting the _C89_CCMODE to 1. Assuming sh is your |
| 527 | login shell then run: |
| 528 | .PP |
| 529 | .Vb 1 |
| 530 | \& export _C89_CCMODE=1 |
| 531 | .Ve |
| 532 | .PP |
