f19b8045 RT |
13 | This document describes various features of IBM's UNIX operating |
14 | system AIX that will affect how Perl version 5 (hereafter just Perl) | |
a318903f | 15 | is compiled and/or runs. |

17 | =head2 Compiling Perl 5 on AIX | |
18 | ||
016af039 | 19 | For information on compilers on older versions of AIX, see L</Compiling |
c5252117 | 20 | Perl 5 on older AIX versions up to 4.3.3>. |
7fabfece RT |
21 | |
22 | When compiling Perl, you must use an ANSI C compiler. AIX does not ship | |
f19b8045 RT |
23 | an ANSI compliant C compiler with AIX by default, but binary builds of |
24 | gcc for AIX are widely available. A version of gcc is also included in | |
25 | the AIX Toolbox which is shipped with AIX. | |
7fabfece RT |
26 | |
27 | =head2 Supported Compilers | |
28 | ||
29 | Currently all versions of IBM's "xlc", "xlc_r", "cc", "cc_r" or | |
c5252117 | 30 | "vac" ANSI/C compiler will work for building Perl if that compiler |
7fabfece RT |
31 | works on your system. |
32 | ||
c5252117 | 33 | If you plan to link Perl to any module that requires thread-support, |
e1051f11 | 34 | like DBD::Oracle, it is better to use the _r version of the compiler. |
c5252117 | 35 | This will not build a threaded Perl, but a thread-enabled Perl. See |
016af039 | 36 | also L</Threaded Perl> later on. |
e1051f11 | 37 | |
1a7c1a8a RT |
38 | As of writing (2010-09) only the I<IBM XL C for AIX> or I<IBM XL C/C++ |
39 | for AIX> compiler is supported by IBM on AIX 5L/6.1/7.1. | |
7fabfece | 40 | |
f19b8045 | 41 | The following compiler versions are currently supported by IBM: |
7fabfece | 42 | |
1a7c1a8a | 43 | IBM XL C and IBM XL C/C++ V8, V9, V10, V11 |
7fabfece | 44 | |
f19b8045 RT |
45 | The XL C for AIX is integrated in the XL C/C++ for AIX compiler and |
46 | therefore also supported. | |
7fabfece | 47 | |
e9d2e818 RT |
48 | If you choose XL C/C++ V9 you need APAR IZ35785 installed |
49 | otherwise the integrated SDBM_File do not compile correctly due | |
50 | to an optimization bug. You can circumvent this problem by | |
51 | adding -qipa to the optimization flags (-Doptimize='-O -qipa'). | |
52 | The PTF for APAR IZ35785 which solves this problem is available | |
e3c125ff | 53 | from IBM (April 2009 PTF for XL C/C++ Enterprise Edition for AIX, V9.0). |
7fabfece | 54 | |
1a7c1a8a RT |
55 | If you choose XL C/C++ V11 you need the April 2010 PTF (or newer) |
56 | installed otherwise you will not get a working Perl version. | |
618c9ef5 | 57 | |
e9d2e818 RT |
58 | Perl can be compiled with either IBM's ANSI C compiler or with gcc. |
59 | The former is recommended, as not only it can compile Perl with no | |
60 | difficulty, but also can take advantage of features listed later | |
7fabfece RT |
61 | that require the use of IBM compiler-specific command-line flags. |
62 | ||
e9d2e818 RT |
63 | If you decide to use gcc, make sure your installation is recent and |
64 | complete, and be sure to read the Perl INSTALL file for more gcc-specific | |
65 | details. Please report any hoops you had to jump through to the | |
7fabfece RT |
66 | development team. |

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

109 | =head2 Building Dynamic Extensions on AIX |
110 | ||
f19b8045 RT |
111 | Starting from Perl 5.7.2 (and consequently 5.8.x / 5.10.x / 5.12.x) |
112 | and AIX 4.3 or newer Perl uses the AIX native dynamic loading interface | |
113 | in the so called runtime linking mode instead of the emulated interface | |
114 | that was used in Perl releases 5.6.1 and earlier or, for AIX releases | |
115 | 4.2 and earlier. This change does break backward compatibility with | |
116 | compiled modules from earlier Perl releases. The change was made to make | |
117 | Perl more compliant with other applications like Apache/mod_perl which are | |
118 | using the AIX native interface. This change also enables the use of | |
119 | C++ code with static constructors and destructors in Perl extensions, | |
7fabfece RT |
120 | which was not possible using the emulated interface. |
121 | ||
122 | It is highly recommended to use the new interface. | |
123 | ||
124 | =head2 Using Large Files with Perl | |
125 | ||
126 | Should yield no problems. | |
127 | ||
128 | =head2 Threaded Perl | |
129 | ||
1a7c1a8a | 130 | Should yield no problems with AIX 5.1 / 5.2 / 5.3 / 6.1 / 7.1. |
7fabfece | 131 | |
81189653 | 132 | IBM uses the AIX system Perl (V5.6.0 on AIX 5.1 and V5.8.2 on |
1a7c1a8a RT |
133 | AIX 5.2 / 5.3 and 6.1; V5.8.8 on AIX 5.3 TL11 and AIX 6.1 TL4; V5.10.1 |
134 | on AIX 7.1) for some AIX system scripts. If you switch the links in | |
135 | /usr/bin from the AIX system Perl (/usr/opt/perl5) to the newly build | |
136 | Perl then you get the same features as with the IBM AIX system Perl if | |
137 | the threaded options are used. | |
7fabfece | 138 | |
c5252117 | 139 | The threaded Perl build works also on AIX 5.1 but the IBM Perl |
81189653 RT |
140 | build (Perl v5.6.0) is not threaded on AIX 5.1. |
141 | ||
1a7c1a8a | 142 | Perl 5.12 an newer is not compatible with the IBM fileset perl.libext. |

144 | =head2 64-bit Perl |
145 | ||
146 | If your AIX system is installed with 64-bit support, you can expect 64-bit | |
147 | configurations to work. If you want to use 64-bit Perl on AIX 6.1 | |
f19b8045 | 148 | you need an APAR for a libc.a bug which affects (n)dbm_XXX functions. |
81189653 | 149 | The APAR number for this problem is IZ39077. |
7fabfece RT |
150 | |
151 | If you need more memory (larger data segment) for your Perl programs you | |
152 | can set: | |
153 | ||
154 | /etc/security/limits | |
155 | default: (or your user) | |
e3c125ff | 156 | data = -1 (default is 262144 * 512 byte) |
7fabfece RT |
157 | |
158 | With the default setting the size is limited to 128MB. | |
f19b8045 | 159 | The -1 removes this limit. If the "make test" fails please change |
e37e7c83 | 160 | your /etc/security/limits as stated above. |

10495b9c | 162 | =head2 Long doubles |
1a78f2f4 JH |
163 | |
164 | IBM calls its implementation of long doubles 128-bit, but it is not | |
165 | the IEEE 128-bit ("quadruple precision") which would give 116 bit of | |
166 | mantissa (nor it is implemented in hardware), instead it's a special | |
167 | software implementation called "double-double", which gives 106 bits | |
168 | of mantissa. | |
169 | ||
170 | There seem to be various problems in this long double implementation. | |
171 | If Configure detects this brokenness, it will disable the long double support. | |
ab473f03 | 172 | This can be overridden with explicit C<-Duselongdouble> (or C<-Dusemorebits>, |
1a78f2f4 JH |
173 | which enables both long doubles and 64 bit integers). If you decide to |
174 | enable long doubles, for most of the broken things Perl has implemented | |
175 | workarounds, but the handling of the special values infinity and NaN | |
176 | remains badly broken: for example infinity plus zero results in NaN. | |
177 | ||
1a7c1a8a | 178 | =head2 Recommended Options AIX 5.1/5.2/5.3/6.1 and 7.1 (threaded/32-bit) |

180 | With the following options you get a threaded Perl version which | |
181 | passes all make tests in threaded 32-bit mode, which is the default | |

250 | =head2 Compiling Perl 5 on AIX 7.1.0 |
251 | ||
252 | A regression in AIX 7 causes a failure in make test in Time::Piece during | |
253 | daylight savings time. APAR IV16514 provides the fix for this. A quick | |
254 | test to see if it's required, assuming it is currently daylight savings | |
255 | in Eastern Time, would be to run C< TZ=EST5 date +%Z >. This will come | |
256 | back with C<EST> normally, but nothing if you have the problem. | |
257 | ||

fe5460cc RT |
259 | =head2 Compiling Perl 5 on older AIX versions up to 4.3.3 |
260 | ||
f19b8045 RT |
261 | Due to the fact that AIX 4.3.3 reached end-of-service in December 31, |
262 | 2003 this information is provided as is. The Perl versions prior to | |
263 | Perl 5.8.9 could be compiled on AIX up to 4.3.3 with the following | |
fe5460cc | 264 | settings (your mileage may vary): |
7fabfece | 265 | |
d5d9880c | 266 | When compiling Perl, you must use an ANSI C compiler. AIX does not ship |
20d11268 MB |
267 | an ANSI compliant C-compiler with AIX by default, but binary builds of |
268 | gcc for AIX are widely available. | |
269 | ||
270 | At the moment of writing, AIX supports two different native C compilers, | |
4951a6f9 | 271 | for which you have to pay: B<xlC> and B<vac>. If you decide to use either |
20d11268 MB |
272 | of these two (which is quite a lot easier than using gcc), be sure to |
273 | upgrade to the latest available patch level. Currently: | |
274 | ||
c67773d0 MB |
275 | 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 |
276 | vac.C 4.4.0.3 or 5.0.2.6 or 6.0.0.1 | |
277 | ||
278 | note that xlC has the OS version in the name as of version 4.0.2.0, so | |
279 | you will find xlC.C for AIX-5.0 as package | |
280 | ||
281 | xlC.aix50.rte 5.0.2.0 or 6.0.0.3 | |
282 | ||
66a1b24b | 283 | subversions are not the same "latest" on all OS versions. For example, |
c67773d0 | 284 | the latest xlC-5 on aix41 is 5.0.2.9, while on aix43, it is 5.0.2.7. |
20d11268 | 285 | |
a318903f MB |
286 | Perl can be compiled with either IBM's ANSI C compiler or with gcc. |
287 | The former is recommended, as not only can it compile Perl with no | |
20d11268 MB |
288 | difficulty, but also can take advantage of features listed later that |
289 | require the use of IBM compiler-specific command-line flags. | |
290 | ||
12f54d27 JH |
291 | The IBM's compiler patch levels 5.0.0.0 and 5.0.1.0 have compiler |
292 | optimization bugs that affect compiling perl.c and regcomp.c, | |
293 | respectively. If Perl's configuration detects those compiler patch | |
294 | levels, optimization is turned off for the said source code files. | |
295 | Upgrading to at least 5.0.2.0 is recommended. | |
296 | ||
20d11268 | 297 | If you decide to use gcc, make sure your installation is recent and |
eed1f4d3 | 298 | complete, and be sure to read the Perl INSTALL file for more gcc-specific |

301 | |
302 | =head2 OS level | |
303 | ||
304 | Before installing the patches to the IBM C-compiler you need to know the | |
305 | level of patching for the Operating System. IBM's command 'oslevel' will | |
64cb7701 MB |
306 | show the base, but is not always complete (in this example oslevel shows |
307 | 4.3.NULL, whereas the system might run most of 4.3.THREE): | |

f19b8045 | 324 | =head2 Building Dynamic Extensions on AIX E<lt> 5L |
20d11268 | 325 | |
8218ea5d JH |
326 | AIX supports dynamically loadable objects as well as shared libraries. |
327 | Shared libraries by convention end with the suffix .a, which is a bit | |
328 | misleading, as an archive can contain static as well as dynamic members. | |
c5252117 | 329 | For Perl dynamically loaded objects we use the .so suffix also used on |
8218ea5d JH |
330 | many other platforms. |
331 | ||
332 | Note that starting from Perl 5.7.2 (and consequently 5.8.0) and AIX 4.3 | |
333 | or newer Perl uses the AIX native dynamic loading interface in the so | |
334 | called runtime linking mode instead of the emulated interface that was | |
335 | used in Perl releases 5.6.1 and earlier or, for AIX releases 4.2 and | |
336 | earlier. This change does break backward compatibility with compiled | |
c5252117 | 337 | modules from earlier Perl releases. The change was made to make Perl |
efc3b6b5 | 338 | more compliant with other applications like Apache/mod_perl which are |
8218ea5d | 339 | using the AIX native interface. This change also enables the use of C++ |
c5252117 | 340 | code with static constructors and destructors in Perl extensions, which |
8218ea5d | 341 | was not possible using the emulated interface. |

349 | but vac 5.0.2.6 or up is highly recommended. Note that since IBM has |
350 | removed vac 5.0.2.1 through 5.0.2.5 from the software depot, these | |
351 | versions should be considered obsolete. | |

353 | Here's a brief lead of how to upgrade the compiler to the latest |
354 | level. Of course this is subject to changes. You can only upgrade | |
355 | versions from ftp-available updates if the first three digit groups | |
356 | are the same (in where you can skip intermediate unlike the patches | |
c5252117 | 357 | in the developer snapshots of Perl), or to one version up where the |
66a1b24b | 358 | "base" is available. In other words, the AIX compiler patches are |

456 | make realclean | |
457 | rm config.sh | |
458 | ./Configure -Dusenm ... | |

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

483 | You may get a warning when doing a threaded build: |
484 | ||
f19b8045 RT |
485 | "pp_sys.c", line 4640.39: 1506-280 (W) Function argument assignment |
486 | between types "unsigned char*" and "const void*" is not allowed. | |
bef58541 JH |
487 | |
488 | The exact line number may vary, but if the warning (W) comes from a line | |
489 | line this | |
490 | ||
491 | hent = PerlSock_gethostbyaddr(addr, (Netdb_hlen_t) addrlen, addrtype); | |
492 | ||
493 | in the "pp_ghostent" function, you may ignore it safely. The warning | |
494 | is caused by the reentrant variant of gethostbyaddr() having a slightly | |
495 | different prototype than its non-reentrant variant, but the difference | |
496 | is not really significant here. | |

20d11268 | 505 | |
12f54d27 JH |
506 | In AIX 4.2 Perl extensions that use C++ functions that use statics |
507 | may have problems in that the statics are not getting initialized. | |
508 | In newer AIX releases this has been solved by linking Perl with | |
509 | the libC_r library, but unfortunately in AIX 4.2 the said library | |
510 | has an obscure bug where the various functions related to time | |
511 | (such as time() and gettimeofday()) return broken values, and | |
512 | therefore in AIX 4.2 Perl is not linked against the libC_r. | |
