407 | Sometimes you want to load old-style "perl libraries" (F<.pl> files), or |
395 | or maybe other weirdly named files. To do that, you need to quote |
408 | maybe other weirdly named files. To support this, the C<--use> option |
396 | the name in single or double quotes (this is because F<staticperl> |
409 | actually tries to do what you mean, depending on the string you specify: |
397 | I<literally> just adds the string after the C<require> - which acts |
410 | |
398 | different when confronted with quoted vs. unquoted strings). When given on |
411 | =over 4 |
399 | the command line, you probably need to quote once more to avoid your shell |
412 | |
400 | interpreting it. Common cases that need this are F<Config_heavy.pl> and |
413 | =item a possibly valid module name, e.g. F<common::sense>, F<Carp>, |
401 | F<utf8_heavy.pl>. |
414 | F<Coro::Mysql>. |
|
|
415 | |
|
|
416 | If the string contains no quotes, no F</> and no F<.>, then C<--use> |
|
|
417 | assumes that it is a normal module name. It will create a new package and |
|
|
418 | evaluate a C<use module> in it, i.e. it will load the package and do a |
|
|
419 | default import. |
|
|
420 | |
|
|
421 | The import step is done because many modules trigger more dependencies |
|
|
422 | when something is imported than without. |
|
|
423 | |
|
|
424 | =item anything that contains F</> or F<.> characters, |
|
|
425 | e.g. F<utf8_heavy.pl>, F<Module/private/data.pl>. |
|
|
426 | |
|
|
427 | The string will be quoted and passed to require, as if you used C<require |
|
|
428 | $module>. Nothing will be imported. |
|
|
429 | |
|
|
430 | =item "path" or 'path', e.g. C<"utf8_heavy.pl">. |
|
|
431 | |
|
|
432 | If you enclose the name into single or double quotes, then the quotes will |
|
|
433 | be removed and the resulting string will be passed to require. This syntax |
|
|
434 | is form compatibility with older versions of staticperl and should not be |

1024 | =item $file = staticperl::find $path |
1278 | This section once contained a way to build fully static (including |
|
|
1279 | uClibc) binaries with buildroot. Unfortunately, buildroot no longer |
|
|
1280 | supports a compiler, so I recommend using alpine linux instead |
|
|
1281 | (L<http://alpinelinux.org/>). Get yourself a VM (e.g. with qemu), run an |
|
|
1282 | older alpine linux verison in it (e.g. 2.4), copy staticperl inside and |

|
1283 | use it. |

1286 | quite dependent on kernel versions, so the newest version of alpine linux |

1038 | =head1 FULLY STATIC BINARIES - UCLIBC AND BUILDROOT |
|
|
1039 | |
|
|
1040 | To make truly static (Linux-) libraries, you might want to have a look at |
|
|
1041 | buildroot (L<http://buildroot.uclibc.org/>). |
|
|
1042 | |
|
|
1043 | Buildroot is primarily meant to set up a cross-compile environment (which |
|
|
1044 | is not so useful as perl doesn't quite like cross compiles), but it can also compile |
|
|
1045 | a chroot environment where you can use F<staticperl>. |
|
|
1046 | |
|
|
1047 | To do so, download buildroot, and enable "Build options => development |
|
|
1048 | files in target filesystem" and optionally "Build options => gcc |
|
|
1049 | optimization level (optimize for size)". At the time of writing, I had |
|
|
1050 | good experiences with GCC 4.4.x but not GCC 4.5. |
|
|
1051 | |
|
|
1052 | To minimise code size, I used C<-pipe -ffunction-sections -fdata-sections |
|
|
1053 | -finline-limit=8 -fno-builtin-strlen -mtune=i386>. The C<-mtune=i386> |
|
|
1054 | doesn't decrease codesize much, but it makes the file much more |
|
|
1055 | compressible. |
|
|
1056 | |
|
|
1057 | If you don't need Coro or threads, you can go with "linuxthreads.old" (or |
|
|
1058 | no thread support). For Coro, it is highly recommended to switch to a |
|
|
1059 | uClibc newer than 0.9.31 (at the time of this writing, I used the 20101201 |
|
|
1060 | snapshot) and enable NPTL, otherwise Coro needs to be configured with the |
|
|
1061 | ultra-slow pthreads backend to work around linuxthreads bugs (it also uses |
|
|
1062 | twice the address space needed for stacks). |
|
|
1063 | |
|
|
1064 | If you use C<linuxthreads.old>, then you should also be aware that |
|
|
1065 | uClibc shares C<errno> between all threads when statically linking. See |
|
|
1066 | L<http://lists.uclibc.org/pipermail/uclibc/2010-June/044157.html> for a |
|
|
1067 | workaround (And L<https://bugs.uclibc.org/2089> for discussion). |
|
|
1068 | |
|
|
1069 | C<ccache> support is also recommended, especially if you want |
|
|
1070 | to play around with buildroot options. Enabling the C<miniperl> |
|
|
1071 | package will probably enable all options required for a successful |
|
|
1072 | perl build. F<staticperl> itself additionally needs either C<wget> |
|
|
1073 | (recommended, for CPAN) or C<curl>. |
|
|
1074 | |
|
|
1075 | As for shells, busybox should provide all that is needed, but the default |
|
|
1076 | busybox configuration doesn't include F<comm> which is needed by perl - |
|
|
1077 | either make a custom busybox config, or compile coreutils. |
|
|
1078 | |
|
|
1079 | For the latter route, you might find that bash has some bugs that keep |
|
|
1080 | it from working properly in a chroot - either use dash (and link it to |
|
|
1081 | F</bin/sh> inside the chroot) or link busybox to F</bin/sh>, using it's |
|
|
1082 | built-in ash shell. |
|
|
1083 | |
|
|
1084 | Finally, you need F</dev/null> inside the chroot for many scripts to work |
|
|
1085 | - F<cp /dev/null output/target/dev> or bind-mounting your F</dev> will |
|
|
1086 | both provide this. |
|
|
1087 | |
|
|
1088 | After you have compiled and set up your buildroot target, you can copy |
|
|
1089 | F<staticperl> from the C<App::Staticperl> distribution or from your |
|
|
1090 | perl f<bin> directory (if you installed it) into the F<output/target> |
|
|
1091 | filesystem, chroot inside and run it. |

1351 | |
|
|
1352 | Glib literally requires Glib to be installed already to build - it tries |
|
|
1353 | to fake this by running Glib out of the build directory before being |
|
|
1354 | built. F<staticperl> tries to work around this by forcing C<MAN1PODS> and |
|

|
|
1362 | |
|
|
1363 | This module hasn't been significantly updated since OpenSSL is called |
|
|
1364 | OpenSSL, and fails to properly link against dependent libraries, most |
|
|
1365 | commonly, it forgets to specify C<-ldl> when linking. |
|
|
1366 | |
|
|
1367 | On GNU/Linux systems this usually goes undetected, as perl usually links |
|
|
1368 | against C<-ldl> itself and OpenSSL just happens to pick it up that way, by |
|
|
1369 | chance. |
|
|
1370 | |
|
|
1371 | For static builds, you either have to configure C<-ldl> manually, or you |
