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 | |
f19b8045 RT |
36 | As of writing (2010-03) 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. | |
7fabfece | 38 | |
f19b8045 | 39 | The following compiler versions are currently supported by IBM: |
7fabfece | 40 | |
f19b8045 | 41 | IBM XL C and IBM XL C/C++ V8, V9, V10 |
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 | |
e9d2e818 RT |
53 | Perl can be compiled with either IBM's ANSI C compiler or with gcc. |
54 | The former is recommended, as not only it can compile Perl with no | |
55 | difficulty, but also can take advantage of features listed later | |
7fabfece RT |
56 | that require the use of IBM compiler-specific command-line flags. |
57 | ||
e9d2e818 RT |
58 | If you decide to use gcc, make sure your installation is recent and |
59 | complete, and be sure to read the Perl INSTALL file for more gcc-specific | |
60 | details. Please report any hoops you had to jump through to the | |
7fabfece RT |
61 | development team. |

e3c125ff RT |
63 | =head2 Incompatibility with AIX Toolbox lib gdbm |
64 | ||
d549c43d RT |
65 | If the AIX Toolbox version of lib gdbm < 1.8.3-5 is installed on your |
66 | system then Perl will not work. This library contains the header files | |
67 | /opt/freeware/include/gdbm/dbm.h|ndbm.h which conflict with the AIX | |
68 | system versions. The lib gdbm will be automatically removed from the | |
69 | wanted libraries if the presence of one of these two header files is | |
f19b8045 RT |
70 | detected. If you want to build Perl with GDBM support then please install |
71 | at least gdbm-devel-1.8.3-5 (or higher). | |
72 | ||
73 | =head2 Perl 5.12 was successfully compiled and tested on: | |

fe5460cc | 94 | |
f19b8045 RT |
95 | All tests were conducted on the oldest supported AIX technology level |
96 | with the latest support package applied. If the tested AIX version is | |
97 | out of support (AIX 4.3.3, 5.1, 5.2) then the last available support | |
98 | level was used. | |

100 | =head2 Building Dynamic Extensions on AIX |
101 | ||
f19b8045 RT |
102 | Starting from Perl 5.7.2 (and consequently 5.8.x / 5.10.x / 5.12.x) |
103 | and AIX 4.3 or newer Perl uses the AIX native dynamic loading interface | |
104 | in the so called runtime linking mode instead of the emulated interface | |
105 | that was used in Perl releases 5.6.1 and earlier or, for AIX releases | |
106 | 4.2 and earlier. This change does break backward compatibility with | |
107 | compiled modules from earlier Perl releases. The change was made to make | |
108 | Perl more compliant with other applications like Apache/mod_perl which are | |
109 | using the AIX native interface. This change also enables the use of | |
110 | C++ code with static constructors and destructors in Perl extensions, | |
7fabfece RT |
111 | which was not possible using the emulated interface. |
112 | ||
113 | It is highly recommended to use the new interface. | |
114 | ||
115 | =head2 Using Large Files with Perl | |
116 | ||
117 | Should yield no problems. | |
118 | ||
119 | =head2 Threaded Perl | |
120 | ||
81189653 | 121 | Should yield no problems with AIX 5.1 / 5.2 / 5.3 and 6.1. |
7fabfece | 122 | |
81189653 | 123 | IBM uses the AIX system Perl (V5.6.0 on AIX 5.1 and V5.8.2 on |
f19b8045 RT |
124 | AIX 5.2 / 5.3 and 6.1; V5.8.8 on AIX 5.3 TL11 and AIX 6.1 TL4) for |
125 | some AIX system scripts. If you switch the links in /usr/bin from the | |
7fabfece | 126 | AIX system Perl (/usr/opt/perl5) to the newly build Perl then you |
f19b8045 RT |
127 | get the same features as with the IBM AIX system Perl if the threaded |
128 | options are used. | |
7fabfece | 129 | |
c5252117 | 130 | The threaded Perl build works also on AIX 5.1 but the IBM Perl |
81189653 RT |
131 | build (Perl v5.6.0) is not threaded on AIX 5.1. |
132 | ||
f19b8045 RT |
133 | Perl 5.12 is not compatible with the IBM fileset perl.libext. |
134 | ||
7fabfece RT |
135 | =head2 64-bit Perl |
136 | ||
137 | If your AIX system is installed with 64-bit support, you can expect 64-bit | |
138 | configurations to work. If you want to use 64-bit Perl on AIX 6.1 | |
f19b8045 | 139 | you need an APAR for a libc.a bug which affects (n)dbm_XXX functions. |
81189653 | 140 | The APAR number for this problem is IZ39077. |
7fabfece RT |
141 | |
142 | If you need more memory (larger data segment) for your Perl programs you | |
143 | can set: | |
144 | ||
145 | /etc/security/limits | |
146 | default: (or your user) | |
e3c125ff | 147 | data = -1 (default is 262144 * 512 byte) |
7fabfece RT |
148 | |
149 | With the default setting the size is limited to 128MB. | |
f19b8045 | 150 | The -1 removes this limit. If the "make test" fails please change |
e37e7c83 | 151 | your /etc/security/limits as stated above. |
7fabfece | 152 | |
e1051f11 | 153 | =head2 Recommended Options AIX 5.1/5.2/5.3 and 6.1 (threaded/32-bit) |

154 | |
155 | With the following options you get a threaded Perl version which | |
156 | passes all make tests in threaded 32-bit mode, which is the default | |
c5252117 | 157 | configuration for the Perl builds that AIX ships with. |

224 | ||
225 | =head2 Compiling Perl 5 on older AIX versions up to 4.3.3 | |
226 | ||
f19b8045 RT |
227 | Due to the fact that AIX 4.3.3 reached end-of-service in December 31, |
228 | 2003 this information is provided as is. The Perl versions prior to | |
229 | Perl 5.8.9 could be compiled on AIX up to 4.3.3 with the following | |
fe5460cc | 230 | settings (your mileage may vary): |
7fabfece | 231 | |
d5d9880c | 232 | When compiling Perl, you must use an ANSI C compiler. AIX does not ship |
20d11268 MB |
233 | an ANSI compliant C-compiler with AIX by default, but binary builds of |
234 | gcc for AIX are widely available. | |
235 | ||
236 | At the moment of writing, AIX supports two different native C compilers, | |
4951a6f9 | 237 | for which you have to pay: B<xlC> and B<vac>. If you decide to use either |
20d11268 MB |
238 | of these two (which is quite a lot easier than using gcc), be sure to |
239 | upgrade to the latest available patch level. Currently: | |
240 | ||
c67773d0 MB |
241 | 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 |
242 | vac.C 4.4.0.3 or 5.0.2.6 or 6.0.0.1 | |
243 | ||
244 | note that xlC has the OS version in the name as of version 4.0.2.0, so | |
245 | you will find xlC.C for AIX-5.0 as package | |
246 | ||
247 | xlC.aix50.rte 5.0.2.0 or 6.0.0.3 | |
248 | ||
66a1b24b | 249 | subversions are not the same "latest" on all OS versions. For example, |
c67773d0 | 250 | the latest xlC-5 on aix41 is 5.0.2.9, while on aix43, it is 5.0.2.7. |
20d11268 | 251 | |
a318903f MB |
252 | Perl can be compiled with either IBM's ANSI C compiler or with gcc. |
253 | The former is recommended, as not only can it compile Perl with no | |
20d11268 MB |
254 | difficulty, but also can take advantage of features listed later that |
255 | require the use of IBM compiler-specific command-line flags. | |
256 | ||
12f54d27 JH |
257 | The IBM's compiler patch levels 5.0.0.0 and 5.0.1.0 have compiler |
258 | optimization bugs that affect compiling perl.c and regcomp.c, | |
259 | respectively. If Perl's configuration detects those compiler patch | |
260 | levels, optimization is turned off for the said source code files. | |
261 | Upgrading to at least 5.0.2.0 is recommended. | |
262 | ||
20d11268 | 263 | If you decide to use gcc, make sure your installation is recent and |
eed1f4d3 | 264 | complete, and be sure to read the Perl INSTALL file for more gcc-specific |

266 | team. | |
20d11268 MB |
267 | |
268 | =head2 OS level | |
269 | ||
270 | Before installing the patches to the IBM C-compiler you need to know the | |
271 | level of patching for the Operating System. IBM's command 'oslevel' will | |
64cb7701 MB |
272 | show the base, but is not always complete (in this example oslevel shows |
273 | 4.3.NULL, whereas the system might run most of 4.3.THREE): | |

f19b8045 | 290 | =head2 Building Dynamic Extensions on AIX E<lt> 5L |
20d11268 | 291 | |
8218ea5d JH |
292 | AIX supports dynamically loadable objects as well as shared libraries. |
293 | Shared libraries by convention end with the suffix .a, which is a bit | |
294 | misleading, as an archive can contain static as well as dynamic members. | |
c5252117 | 295 | For Perl dynamically loaded objects we use the .so suffix also used on |
8218ea5d JH |
296 | many other platforms. |
297 | ||
298 | Note that starting from Perl 5.7.2 (and consequently 5.8.0) and AIX 4.3 | |
299 | or newer Perl uses the AIX native dynamic loading interface in the so | |
300 | called runtime linking mode instead of the emulated interface that was | |
301 | used in Perl releases 5.6.1 and earlier or, for AIX releases 4.2 and | |
302 | earlier. This change does break backward compatibility with compiled | |
c5252117 | 303 | modules from earlier Perl releases. The change was made to make Perl |
efc3b6b5 | 304 | more compliant with other applications like Apache/mod_perl which are |
8218ea5d | 305 | using the AIX native interface. This change also enables the use of C++ |
c5252117 | 306 | code with static constructors and destructors in Perl extensions, which |
8218ea5d | 307 | was not possible using the emulated interface. |

c67773d0 MB |
315 | but vac 5.0.2.6 or up is highly recommended. Note that since IBM has |
316 | removed vac 5.0.2.1 through 5.0.2.5 from the software depot, these | |
317 | versions should be considered obsolete. | |

319 | Here's a brief lead of how to upgrade the compiler to the latest |
320 | level. Of course this is subject to changes. You can only upgrade | |
321 | versions from ftp-available updates if the first three digit groups | |
322 | are the same (in where you can skip intermediate unlike the patches | |
c5252117 | 323 | in the developer snapshots of Perl), or to one version up where the |
66a1b24b | 324 | "base" is available. In other words, the AIX compiler patches are |

419 | ||
420 | make realclean | |
421 | rm config.sh | |
422 | ./Configure -Dusenm ... | |
423 | ||
424 | which makes Configure to use the C<nm> tool when scanning for library | |
425 | symbols, which usually is not done in AIX. | |
426 | ||

427 | Related to this, you probably should not use the C<-r> option of |
428 | Configure in AIX, because that affects of how the C<nm> tool is used. | |

c67773d0 MB |
432 | Using gcc-3.x (tested with 3.0.4, 3.1, and 3.2) now works out of the box, |
433 | as do recent gcc-2.9 builds available directly from IBM as part of their | |
434 | Linux compatibility packages, available here: | |

447 | You may get a warning when doing a threaded build: |
448 | ||
f19b8045 RT |
449 | "pp_sys.c", line 4640.39: 1506-280 (W) Function argument assignment |
450 | between types "unsigned char*" and "const void*" is not allowed. | |
bef58541 JH |
451 | |
452 | The exact line number may vary, but if the warning (W) comes from a line | |
453 | line this | |
454 | ||
455 | hent = PerlSock_gethostbyaddr(addr, (Netdb_hlen_t) addrlen, addrtype); | |
456 | ||
457 | in the "pp_ghostent" function, you may ignore it safely. The warning | |
458 | is caused by the reentrant variant of gethostbyaddr() having a slightly | |
459 | different prototype than its non-reentrant variant, but the difference | |
460 | is not really significant here. | |

f19b8045 | 462 | =head2 64-bit Perl E<lt> 5L |
20d11268 | 463 | |
1d69df2b | 464 | If your AIX is installed with 64-bit support, you can expect 64-bit |

465 | configurations to work. In combination with threads some tests might |
466 | still fail. | |

12f54d27 | 468 | =head2 AIX 4.2 and extensions using C++ with statics |
20d11268 | 469 | |
12f54d27 JH |
470 | In AIX 4.2 Perl extensions that use C++ functions that use statics |
471 | may have problems in that the statics are not getting initialized. | |
472 | In newer AIX releases this has been solved by linking Perl with | |
473 | the libC_r library, but unfortunately in AIX 4.2 the said library | |
474 | has an obscure bug where the various functions related to time | |
475 | (such as time() and gettimeofday()) return broken values, and | |
476 | therefore in AIX 4.2 Perl is not linked against the libC_r. | |
