10 | |
f19b8045 |
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 |
19 | |
20 | When compiling Perl, you must use an ANSI C compiler. AIX does not ship |
f19b8045 |
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 |
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 |
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 |
33 | This will not build a threaded Perl, but a thread-enabled Perl. See |
34 | also L<Threaded Perl> later on. |
e1051f11 |
35 | |
f19b8045 |
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 |
43 | The XL C for AIX is integrated in the XL C/C++ for AIX compiler and |
44 | therefore also supported. |
7fabfece |
45 | |
e9d2e818 |
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 |
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 |
56 | that require the use of IBM compiler-specific command-line flags. |
57 | |
e9d2e818 |
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 |
61 | development team. |
62 | |
e3c125ff |
63 | =head2 Incompatibility with AIX Toolbox lib gdbm |
64 | |
d549c43d |
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 |
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: |
74 | |

e3c125ff |

91 | |
f19b8045 |
92 | Successfully tested means that all "make test" runs finish with a |
e37e7c83 |
93 | result of 100% OK. All tests were conducted with -Duseshrplib set. |
fe5460cc |
94 | |
f19b8045 |
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 |
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 |
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 |
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 |
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 |
131 | build (Perl v5.6.0) is not threaded on AIX 5.1. |
132 | |
f19b8045 |
133 | Perl 5.12 is not compatible with the IBM fileset perl.libext. |
134 | |
7fabfece |
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 |
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 |
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. |

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 |

222 | -Dcc='gcc -maix64' |
223 | |
224 | |
225 | =head2 Compiling Perl 5 on older AIX versions up to 4.3.3 |
226 | |
f19b8045 |
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 |
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 |
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 |
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 |
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 |
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 |
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 |
60ecc970 |
265 | details. Please report any hoops you had to jump through to the development |
266 | team. |
20d11268 |
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 |
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): |
1a3e4d88 |
274 | |
20d11268 |

c5252117 |
282 | The same might happen to AIX 5.1 or other OS levels. As a side note, Perl |
64cb7701 |
283 | cannot be built without bos.adt.syscalls and bos.adt.libm installed |

290 | =head2 Building Dynamic Extensions on AIX E<lt> 5L |
20d11268 |
291 | |
8218ea5d |
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 |
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. |

309 | =head2 The IBM ANSI C Compiler |
310 | |
311 | All defaults for Configure can be used. |
312 | |
313 | If you've chosen to use vac 4, be sure to run 4.4.0.3. Older versions |
4951a6f9 |
314 | will turn up nasty later on. For vac 5 be sure to run at least 5.0.1.0, |
c67773d0 |
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. |
20d11268 |
318 | |
a318903f |
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 |
a318903f |
325 | cumulative. |
326 | |
327 | vac.C.4.4.0.1 => vac.C.4.4.0.3 is OK (vac.C.4.4.0.2 not needed) |

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. |

432 | Using gcc-3.x (tested with 3.0.4, 3.1, and 3.2) now works out of the box, |

444 | Threads seem to work OK, though at the moment not all tests pass when |

445 | threads are used in combination with 64-bit configurations. |

447 | You may get a warning when doing a threaded build: |
448 | |
f19b8045 |
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 |
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. |

1d69df2b |
464 | If your AIX is installed with 64-bit support, you can expect 64-bit |
12f54d27 |
465 | configurations to work. In combination with threads some tests might |
466 | still fail. |

468 | =head2 AIX 4.2 and extensions using C++ with statics |
20d11268 |
469 | |
12f54d27 |
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. |
