f19b8045 RT |
11 | This document describes various features of IBM's UNIX operating |
12 | system AIX that will affect how Perl version 5 (hereafter just Perl) | |
a318903f | 13 | is compiled and/or runs. |

15 | =head2 Compiling Perl 5 on AIX | |
16 | ||
f19b8045 | 17 | For information on compilers on older versions of AIX, see L<Compiling |
c5252117 | 18 | Perl 5 on older AIX versions up to 4.3.3>. |
7fabfece RT |
19 | |
20 | When compiling Perl, you must use an ANSI C compiler. AIX does not ship | |
f19b8045 RT |
21 | an ANSI compliant C compiler with AIX by default, but binary builds of |
22 | gcc for AIX are widely available. A version of gcc is also included in | |
23 | the AIX Toolbox which is shipped with AIX. | |
7fabfece RT |
24 | |
25 | =head2 Supported Compilers | |
26 | ||
27 | Currently all versions of IBM's "xlc", "xlc_r", "cc", "cc_r" or | |
c5252117 | 28 | "vac" ANSI/C compiler will work for building Perl if that compiler |
7fabfece RT |
29 | works on your system. |
30 | ||
c5252117 | 31 | If you plan to link Perl to any module that requires thread-support, |
e1051f11 | 32 | like DBD::Oracle, it is better to use the _r version of the compiler. |
c5252117 RT |
33 | This will not build a threaded Perl, but a thread-enabled Perl. See |
34 | also L<Threaded Perl> later on. | |
e1051f11 | 35 | |
1a7c1a8a RT |
36 | As of writing (2010-09) only the I<IBM XL C for AIX> or I<IBM XL C/C++ |
37 | for AIX> compiler is supported by IBM on AIX 5L/6.1/7.1. | |
7fabfece | 38 | |
f19b8045 | 39 | The following compiler versions are currently supported by IBM: |
7fabfece | 40 | |
1a7c1a8a | 41 | IBM XL C and IBM XL C/C++ V8, V9, V10, V11 |
7fabfece | 42 | |
f19b8045 RT |
43 | The XL C for AIX is integrated in the XL C/C++ for AIX compiler and |
44 | therefore also supported. | |
7fabfece | 45 | |
e9d2e818 RT |
46 | If you choose XL C/C++ V9 you need APAR IZ35785 installed |
47 | otherwise the integrated SDBM_File do not compile correctly due | |
48 | to an optimization bug. You can circumvent this problem by | |
49 | adding -qipa to the optimization flags (-Doptimize='-O -qipa'). | |
50 | The PTF for APAR IZ35785 which solves this problem is available | |
e3c125ff | 51 | from IBM (April 2009 PTF for XL C/C++ Enterprise Edition for AIX, V9.0). |
7fabfece | 52 | |
1a7c1a8a RT |
53 | If you choose XL C/C++ V11 you need the April 2010 PTF (or newer) |
54 | installed otherwise you will not get a working Perl version. | |
618c9ef5 | 55 | |
e9d2e818 RT |
56 | Perl can be compiled with either IBM's ANSI C compiler or with gcc. |
57 | The former is recommended, as not only it can compile Perl with no | |
58 | difficulty, but also can take advantage of features listed later | |
7fabfece RT |
59 | that require the use of IBM compiler-specific command-line flags. |
60 | ||
e9d2e818 RT |
61 | If you decide to use gcc, make sure your installation is recent and |
62 | complete, and be sure to read the Perl INSTALL file for more gcc-specific | |
63 | details. Please report any hoops you had to jump through to the | |
7fabfece RT |
64 | development team. |

66 | =head2 Incompatibility with AIX Toolbox lib gdbm |
67 | ||
d549c43d RT |
68 | If the AIX Toolbox version of lib gdbm < 1.8.3-5 is installed on your |
69 | system then Perl will not work. This library contains the header files | |
70 | /opt/freeware/include/gdbm/dbm.h|ndbm.h which conflict with the AIX | |
71 | system versions. The lib gdbm will be automatically removed from the | |
72 | wanted libraries if the presence of one of these two header files is | |
f19b8045 RT |
73 | detected. If you want to build Perl with GDBM support then please install |
74 | at least gdbm-devel-1.8.3-5 (or higher). | |

107 | =head2 Building Dynamic Extensions on AIX |
108 | ||
f19b8045 RT |
109 | Starting from Perl 5.7.2 (and consequently 5.8.x / 5.10.x / 5.12.x) |
110 | and AIX 4.3 or newer Perl uses the AIX native dynamic loading interface | |
111 | in the so called runtime linking mode instead of the emulated interface | |
112 | that was used in Perl releases 5.6.1 and earlier or, for AIX releases | |
113 | 4.2 and earlier. This change does break backward compatibility with | |
114 | compiled modules from earlier Perl releases. The change was made to make | |
115 | Perl more compliant with other applications like Apache/mod_perl which are | |
116 | using the AIX native interface. This change also enables the use of | |
117 | C++ code with static constructors and destructors in Perl extensions, | |
7fabfece RT |
118 | which was not possible using the emulated interface. |
119 | ||
120 | It is highly recommended to use the new interface. | |
121 | ||
122 | =head2 Using Large Files with Perl | |
123 | ||
124 | Should yield no problems. | |
125 | ||
126 | =head2 Threaded Perl | |
127 | ||
1a7c1a8a | 128 | Should yield no problems with AIX 5.1 / 5.2 / 5.3 / 6.1 / 7.1. |
7fabfece | 129 | |
81189653 | 130 | IBM uses the AIX system Perl (V5.6.0 on AIX 5.1 and V5.8.2 on |
1a7c1a8a RT |
131 | AIX 5.2 / 5.3 and 6.1; V5.8.8 on AIX 5.3 TL11 and AIX 6.1 TL4; V5.10.1 |
132 | on AIX 7.1) for some AIX system scripts. If you switch the links in | |
133 | /usr/bin from the AIX system Perl (/usr/opt/perl5) to the newly build | |
134 | Perl then you get the same features as with the IBM AIX system Perl if | |
135 | the threaded options are used. | |
7fabfece | 136 | |
c5252117 | 137 | The threaded Perl build works also on AIX 5.1 but the IBM Perl |
81189653 RT |
138 | build (Perl v5.6.0) is not threaded on AIX 5.1. |
139 | ||
1a7c1a8a | 140 | Perl 5.12 an newer is not compatible with the IBM fileset perl.libext. |

142 | =head2 64-bit Perl |
143 | ||
144 | If your AIX system is installed with 64-bit support, you can expect 64-bit | |
145 | configurations to work. If you want to use 64-bit Perl on AIX 6.1 | |
f19b8045 | 146 | you need an APAR for a libc.a bug which affects (n)dbm_XXX functions. |
81189653 | 147 | The APAR number for this problem is IZ39077. |
7fabfece RT |
148 | |
149 | If you need more memory (larger data segment) for your Perl programs you | |
150 | can set: | |
151 | ||
152 | /etc/security/limits | |
153 | default: (or your user) | |
e3c125ff | 154 | data = -1 (default is 262144 * 512 byte) |
7fabfece RT |
155 | |
156 | With the default setting the size is limited to 128MB. | |
f19b8045 | 157 | The -1 removes this limit. If the "make test" fails please change |
e37e7c83 | 158 | your /etc/security/limits as stated above. |

162 | With the following options you get a threaded Perl version which | |
163 | passes all make tests in threaded 32-bit mode, which is the default | |
c5252117 | 164 | configuration for the Perl builds that AIX ships with. |

232 | =head2 Compiling Perl 5 on AIX 7.1.0 |
233 | ||
234 | A regression in AIX 7 causes a failure in make test in Time::Piece during | |
235 | daylight savings time. APAR IV16514 provides the fix for this. A quick | |
236 | test to see if it's required, assuming it is currently daylight savings | |
237 | in Eastern Time, would be to run C< TZ=EST5 date +%Z >. This will come | |
238 | back with C<EST> normally, but nothing if you have the problem. | |
239 | ||
240 | ||
fe5460cc RT |
241 | =head2 Compiling Perl 5 on older AIX versions up to 4.3.3 |
242 | ||
f19b8045 RT |
243 | Due to the fact that AIX 4.3.3 reached end-of-service in December 31, |
244 | 2003 this information is provided as is. The Perl versions prior to | |
245 | Perl 5.8.9 could be compiled on AIX up to 4.3.3 with the following | |
fe5460cc | 246 | settings (your mileage may vary): |
7fabfece | 247 | |
d5d9880c | 248 | When compiling Perl, you must use an ANSI C compiler. AIX does not ship |
20d11268 MB |
249 | an ANSI compliant C-compiler with AIX by default, but binary builds of |
250 | gcc for AIX are widely available. | |
251 | ||
252 | At the moment of writing, AIX supports two different native C compilers, | |
4951a6f9 | 253 | for which you have to pay: B<xlC> and B<vac>. If you decide to use either |
20d11268 MB |
254 | of these two (which is quite a lot easier than using gcc), be sure to |
255 | upgrade to the latest available patch level. Currently: | |
256 | ||
c67773d0 MB |
257 | xlC.C 3.1.4.10 or 3.6.6.0 or 4.0.2.2 or 5.0.2.9 or 6.0.0.3 |
258 | vac.C 4.4.0.3 or 5.0.2.6 or 6.0.0.1 | |
259 | ||
260 | note that xlC has the OS version in the name as of version 4.0.2.0, so | |
261 | you will find xlC.C for AIX-5.0 as package | |
262 | ||
263 | xlC.aix50.rte 5.0.2.0 or 6.0.0.3 | |
264 | ||
66a1b24b | 265 | subversions are not the same "latest" on all OS versions. For example, |
c67773d0 | 266 | the latest xlC-5 on aix41 is 5.0.2.9, while on aix43, it is 5.0.2.7. |
20d11268 | 267 | |
a318903f MB |
268 | Perl can be compiled with either IBM's ANSI C compiler or with gcc. |
269 | The former is recommended, as not only can it compile Perl with no | |
20d11268 MB |
270 | difficulty, but also can take advantage of features listed later that |
271 | require the use of IBM compiler-specific command-line flags. | |
272 | ||
12f54d27 JH |
273 | The IBM's compiler patch levels 5.0.0.0 and 5.0.1.0 have compiler |
274 | optimization bugs that affect compiling perl.c and regcomp.c, | |
275 | respectively. If Perl's configuration detects those compiler patch | |
276 | levels, optimization is turned off for the said source code files. | |
277 | Upgrading to at least 5.0.2.0 is recommended. | |
278 | ||
20d11268 | 279 | If you decide to use gcc, make sure your installation is recent and |
eed1f4d3 | 280 | complete, and be sure to read the Perl INSTALL file for more gcc-specific |

284 | =head2 OS level | |
285 | ||
286 | Before installing the patches to the IBM C-compiler you need to know the | |
287 | level of patching for the Operating System. IBM's command 'oslevel' will | |
64cb7701 MB |
288 | show the base, but is not always complete (in this example oslevel shows |
289 | 4.3.NULL, whereas the system might run most of 4.3.THREE): | |

f19b8045 | 306 | =head2 Building Dynamic Extensions on AIX E<lt> 5L |
20d11268 | 307 | |
8218ea5d JH |
308 | AIX supports dynamically loadable objects as well as shared libraries. |
309 | Shared libraries by convention end with the suffix .a, which is a bit | |
310 | misleading, as an archive can contain static as well as dynamic members. | |
c5252117 | 311 | For Perl dynamically loaded objects we use the .so suffix also used on |
8218ea5d JH |
312 | many other platforms. |
313 | ||
314 | Note that starting from Perl 5.7.2 (and consequently 5.8.0) and AIX 4.3 | |
315 | or newer Perl uses the AIX native dynamic loading interface in the so | |
316 | called runtime linking mode instead of the emulated interface that was | |
317 | used in Perl releases 5.6.1 and earlier or, for AIX releases 4.2 and | |
318 | earlier. This change does break backward compatibility with compiled | |
c5252117 | 319 | modules from earlier Perl releases. The change was made to make Perl |
efc3b6b5 | 320 | more compliant with other applications like Apache/mod_perl which are |
8218ea5d | 321 | using the AIX native interface. This change also enables the use of C++ |
c5252117 | 322 | code with static constructors and destructors in Perl extensions, which |
8218ea5d | 323 | was not possible using the emulated interface. |

329 | If you've chosen to use vac 4, be sure to run 4.4.0.3. Older versions | |
4951a6f9 | 330 | will turn up nasty later on. For vac 5 be sure to run at least 5.0.1.0, |
c67773d0 MB |
331 | but vac 5.0.2.6 or up is highly recommended. Note that since IBM has |
332 | removed vac 5.0.2.1 through 5.0.2.5 from the software depot, these | |
333 | versions should be considered obsolete. | |
20d11268 | 334 | |
a318903f MB |
335 | Here's a brief lead of how to upgrade the compiler to the latest |
336 | level. Of course this is subject to changes. You can only upgrade | |
337 | versions from ftp-available updates if the first three digit groups | |
338 | are the same (in where you can skip intermediate unlike the patches | |
c5252117 | 339 | in the developer snapshots of Perl), or to one version up where the |
66a1b24b | 340 | "base" is available. In other words, the AIX compiler patches are |

434 | you could retry with | |
435 | ||
436 | make realclean | |
437 | rm config.sh | |
438 | ./Configure -Dusenm ... | |
439 | ||
440 | which makes Configure to use the C<nm> tool when scanning for library | |
441 | symbols, which usually is not done in AIX. | |
442 | ||
dd993642 JH |
443 | Related to this, you probably should not use the C<-r> option of |
444 | Configure in AIX, because that affects of how the C<nm> tool is used. | |

c5252117 | 446 | =head2 Using GNU's gcc for building Perl |
20d11268 | 447 | |
c67773d0 MB |
448 | Using gcc-3.x (tested with 3.0.4, 3.1, and 3.2) now works out of the box, |
449 | as do recent gcc-2.9 builds available directly from IBM as part of their | |
450 | Linux compatibility packages, available here: | |

20d11268 | 459 | |
60ecc970 | 460 | Threads seem to work OK, though at the moment not all tests pass when |
1d69df2b | 461 | threads are used in combination with 64-bit configurations. |
20d11268 | 462 | |

463 | You may get a warning when doing a threaded build: |
464 | ||
f19b8045 RT |
465 | "pp_sys.c", line 4640.39: 1506-280 (W) Function argument assignment |
466 | between types "unsigned char*" and "const void*" is not allowed. | |
bef58541 JH |
467 | |
468 | The exact line number may vary, but if the warning (W) comes from a line | |
469 | line this | |
470 | ||
471 | hent = PerlSock_gethostbyaddr(addr, (Netdb_hlen_t) addrlen, addrtype); | |
472 | ||
473 | in the "pp_ghostent" function, you may ignore it safely. The warning | |
474 | is caused by the reentrant variant of gethostbyaddr() having a slightly | |
475 | different prototype than its non-reentrant variant, but the difference | |
476 | is not really significant here. | |

f19b8045 | 478 | =head2 64-bit Perl E<lt> 5L |
20d11268 | 479 | |
1d69df2b | 480 | If your AIX is installed with 64-bit support, you can expect 64-bit |
12f54d27 JH |
481 | configurations to work. In combination with threads some tests might |
482 | still fail. | |

12f54d27 | 484 | =head2 AIX 4.2 and extensions using C++ with statics |
20d11268 | 485 | |
12f54d27 JH |
486 | In AIX 4.2 Perl extensions that use C++ functions that use statics |
487 | may have problems in that the statics are not getting initialized. | |
488 | In newer AIX releases this has been solved by linking Perl with | |
489 | the libC_r library, but unfortunately in AIX 4.2 the said library | |
490 | has an obscure bug where the various functions related to time | |
491 | (such as time() and gettimeofday()) return broken values, and | |
492 | therefore in AIX 4.2 Perl is not linked against the libC_r. | |
