128 | The \*(sw tool attempts to take a lot of the work out of building and |
129 | installing source packages across multiple architectures. This section |
130 | will describe how to use \*(sw's features to best advantage in a number |
131 | of common situations. |
3315e8b3 |
132 | .PP |
133 | To keep things concrete, I'll describe how things are done at the EBI, |
91f52355 |
134 | although there's nothing EBI-specific about the \*(sw program itself. |
135 | For details about how we handle software at EBI, see the |
3315e8b3 |
136 | .B Local quirks |
137 | section below. |
138 | .PP |
139 | By the way, this is quite a large manual. I recommend that you print a |
140 | copy onto paper and peruse it in a leisurely fashion, rather than |
141 | squinting at a monitor. |

3315e8b3 |
179 | .SH "8 STEPS TO INSTALLING A PACKAGE" |
be07bee0 |
180 | . |
3315e8b3 |
181 | The following steps will guide you through your first (and maybe second) |
182 | package installations. In the description, I'll use |
183 | .RI ` package ' |
184 | to refer to the package's name, and |
185 | .RI ` version ' |
186 | to refer to its version number. |
187 | .PP |
188 | Not all the important features and options are described in this part of |
91f52355 |
189 | the manual. View it more as a taster for the sorts of things \*(sw can |
190 | do, and a suggestion |
3315e8b3 |
191 | .SS "1. Download the source distribution" |
192 | Download the package's source distribution. This will normally be in an |
193 | archive called something like |
194 | .IB package - version .tar.gz\c |
195 | \&. At EBI, we put source archive files in |
196 | .BR /sw/common/tr . |
197 | .SS "2. Unpack the source tree" |
198 | Unpack the source tree into the standard source directory. Each source |
199 | tree should have its own directory. Most well-packaged source |
200 | distributions unpack themselves into a neat directory, but less |
201 | fastidious programmers make archives which scatter files all over the |
202 | current directory. |
203 | .PP |
204 | At EBI, we put the source trees in |
205 | .BR /sw/common/src , |
206 | so unpacking a well-formed source distribution looks like: |
207 | .VS |
208 | cd /sw/common/src |
209 | .BI "gzip \-dc ../tr/" package \- version ".tar.gz | tar xfv \-" |
210 | .VE |
211 | Ill-formed source distributions involve making the directory for the |
212 | package first, changing into it, and then unpacking into the current |
213 | directory: |
214 | .VS |
215 | cd /sw/common/src |
216 | .BI "mkdir " package \- version |
217 | .BI "cd " package \- version |
218 | .BI "gzip \-dc ../../tr/" package - version ".tar.gz | tar xfv \-" |
219 | .VE |
220 | When you've finished unpacking, make sure that your current directory is |
221 | the top level directory of the source tree you unpacked. |
91f52355 |
222 | .SS "3. Tell \\*(sw what you're up to" |
223 | Now you need to tell \*(sw what you're working on. It will keep track of |
224 | this and other bits of information in a little file and refer to it |
225 | every now and then. It will also whinge at you and refuse to cooperate |
226 | if it can't find its little file, so it's as well to oblige. |
3315e8b3 |
227 | .PP |
91f52355 |
228 | To tell \*(sw to create this little file and initialize it with sensible |
229 | values, you just need to say |
3315e8b3 |
230 | .VS |
231 | .BI "sw setup " "package version" |
232 | .VE |
233 | What could be easier? |
234 | .SS "4. Restrict the build to particular architectures" |
235 | Some packages don't work on all architectures, either because the author |
236 | wasn't sufficiently good at writing portable software, or because the |
237 | program's doing inherently nonportable things. |
238 | .PP |
91f52355 |
239 | If that's the case, then you need to tell \*(sw to only build on the |
240 | architectures that really work. Do this with the |
3315e8b3 |
241 | .RB ` "sw only" ' |
242 | command. For example, if your package only works on Linux and Solaris, |
243 | say: |
244 | .VS |
245 | sw only i386-linux sparc-solaris |
246 | .VE |
91f52355 |
247 | You can get a list of the architecture names that \*(sw understands by |
248 | typing |
3315e8b3 |
249 | .VS |
250 | sw listarch |
251 | .VE |
252 | With a little bit of luck, these names ought to be self-explanatory. |
253 | .PP |
254 | If your package is properly portable and works everywhere then you don't |
255 | need to do anything for this step. Skip on to the next one. |
256 | .SS "5. Configure the package" |
257 | Now it gets complicated. If the package you're building uses |
91f52355 |
258 | .B Autoconf |
3315e8b3 |
259 | to configure itself for its current environment then you're in luck. |
260 | You can tell an |
91f52355 |
261 | .B Autoconf |
3315e8b3 |
262 | package because there's a script called |
263 | .B configure |
264 | in the top source directory, and a file called |
265 | .BR Makefile.in . |
266 | If it |
267 | .I does |
268 | use |
91f52355 |
269 | .B Autoconf |
3315e8b3 |
270 | then run |
271 | .VS |
272 | sw configure |
273 | .VE |
274 | to configure the package on all the platforms it's meant to be built |
275 | for. When you've done that, move onto the next step. |
276 | .PP |
277 | If the package |
278 | .I doesn't |
279 | use |
91f52355 |
280 | .B Autoconf |
3315e8b3 |
281 | then all is not lost (although it may be worthwhile complaining at the |
282 | package's author or maintainers). You need to make a collection of |
283 | .IR "link trees" , |
284 | one for each architecture. These link trees are little replicas of the |
285 | main source tree but with symbolic links instead of the real source |
286 | files. To make the link trees, run |
287 | .VS |
288 | sw linktree |
289 | .VE |
290 | Now, that's not actually quite what you wanted. It's made a link for |
291 | .I every |
292 | file in the source tree. Unfortunately, there are some files you'll |
293 | (probably) have to modify for each architecture in order to configure |
294 | the package to build properly. You can turn links in the link trees |
295 | into real independently editable files by |
296 | .I snapping |
297 | the links. Say for example that |
298 | .B Makefile |
299 | and |
300 | .B config.h |
301 | need to be modified for each architecture. Running the command |
302 | .VS |
303 | sw snaplink Makefile config.h |
304 | .VE |
305 | is sufficient to do the right thing. |
306 | .PP |
307 | Now you must edit the snapped files to configure the package. Make sure |
308 | that the install directories are correctly set. At EBI, all the |
309 | software should be configured so that architecture neutral files end up |
310 | under |
311 | .B /sw/common |
312 | and architecture-specific files end up under |
313 | .BI /sw/common/arch/ arch\c |
314 | \&. |
315 | .SS "6. Build the package" |
316 | Now you've laid the groundwork, everything ought to be easy. Making the |
317 | program ought to involve simply typing |
318 | .VS |
319 | sw make |
320 | .VE |
321 | and waiting for a while. If you had the |
322 | .B curses |
91f52355 |
323 | library available when \*(sw was built, then your terminal will split |
324 | itself into little independently scrolling windows showing you the |
325 | progress for each architecture. If you're not privileged enough to have |
3315e8b3 |
326 | .B curses |
327 | then you get the output appropriately tagged with architecture names, |
328 | which is unfortunately fairly hard to read. |
329 | .SS "7. Install the package" |
330 | Most source packages (and almost certainly all |
91f52355 |
331 | .B Autoconf |
3315e8b3 |
332 | ones) have a |
333 | .B make |
334 | target |
335 | .RB ` install ' |
91f52355 |
336 | which installs the program correctly. You can run this from \*(sw by |
337 | saying |
3315e8b3 |
338 | .VS |
339 | sw \-i make install |
340 | .VE |
341 | The little |
342 | .RB ` \-i ' |
91f52355 |
343 | option there tells \*(sw that this is the |
3315e8b3 |
344 | .IR "install step" . |
345 | When an architecture completes this step correctly, it's marked as being |
91f52355 |
346 | properly installed, and \*(sw doesn't bother thinking about it again. |
3315e8b3 |
347 | .PP |
348 | If you |
349 | .I don't |
350 | have an |
351 | .RB ` install ' |
352 | makefile target, then you have to install things manually. That's not |
353 | much fun, so moan at the package's author. When you've finished |
354 | fiddling with installation, run |
355 | .VS |
356 | sw -i run true |
357 | .VE |
91f52355 |
358 | just to tell \*(sw that you've installed everything OK. (This is a bit |
359 | of a kludge.) |
3315e8b3 |
360 | .SS "8. Update the index" |
361 | Now that everything's built and installed, there's just one more command |
362 | to type: |
363 | .VS |
364 | sw commit |
365 | .VE |
91f52355 |
366 | This makes \*(sw update its main index of installed packages, telling it |
367 | which architectures packages are installed on, and who did it. |

373 | That was a gentle introduction. This section contains the complete |
374 | reference to |
375 | .BR sw : |
376 | far more detail that you probably want. If that's really the case, try |
377 | running |

379 | sw \-\-help\-full |
380 | .VE |
381 | to read the available help text. There's quite a lot of it, and it |
382 | ought to keep you occupied for a while. |
383 | .PP |
91f52355 |
384 | The basic \*(sw command line looks a bit like: |
3315e8b3 |
385 | .sp 1 |
91f52355 |
386 | .RS 5 |
387 | .B sw |

393 | If you just say |
394 | .VS |
395 | sw |
396 | .VE |
91f52355 |
397 | at the shell prompt, \*(sw gives you an extremely terse usage summary |
398 | and quits. You have to tell it to do |
3315e8b3 |
399 | .IR something . |
91f52355 |
400 | Most of the time you do this by giving \*(sw a |
3315e8b3 |
401 | .IR command , |
402 | like |
403 | .RB ` setup ' |
404 | or |
405 | .RB ` make ' |
406 | so that it knows what to do. There are some strange command line |
91f52355 |
407 | options which cause \*(sw to do more exotic things, though. |

413 | The \*(sw program that users use is really a small architecture-neutral |
414 | shell script, which works out the current architecture and executes the |
3315e8b3 |
415 | appropriate architecture-specific main program. It's done this way so |
91f52355 |
416 | that \*(sw knows that it can use the shell script to start itself up on |
417 | a remote host with a different architecture, something which it does |
418 | quite a lot. The only feature provided by the front-end shell script is |
419 | the |

91f52355 |
429 | environment variable. The \*(sw program will read space-separated |
430 | options from this variable before it reads the command line itself. |
3315e8b3 |
431 | .PP |
91f52355 |
432 | The \*(sw program usually understands two different names for each |
433 | option: a traditional Unix single-character name, and a long GNU-style |
434 | name. The short options behave in the normal Unix way: you can join |
435 | them together into single words with a |
3315e8b3 |
436 | .RB ` \- ' |
437 | at the front, for example. The long names are always preceded by a |
438 | double dash. You can abbreviate long names as much as you like, as long |
439 | as the resulting abbreviation is unambiguous. In the descriptions |
440 | below, both the short and long names of the options are shown, but for |
441 | reasons of brevity required arguments are only shown for the long form. |
442 | .PP |
91f52355 |
443 | There are conceptually two types of \*(sw command line options: those |
444 | which, usually for reasons of consistency with other programs, cause |
445 | \*(sw to do something immediately; and those which store some settings |
446 | for particular commands. The latter type are generally more useful. |
447 | It's worth bearing in mind, though, that the options are only used by a |
448 | few commands. The command reference describes exactly which commands |
449 | use which options. |
3315e8b3 |
450 | .PP |
451 | The complete list of command line options understood by the current |
91f52355 |
452 | version of \*(sw is as follows: |
3315e8b3 |
453 | .TP |
454 | .B "\-h, \-\-help" |
91f52355 |
455 | Writes a fairly brief summary of \*(sw's command line options and a usage line for each of \*(sw's commands to standard output, and exits successfully. |
3315e8b3 |
456 | .TP |
457 | .B "\-H, \-\-help\-full" |
91f52355 |
458 | Writes a summary of \*(sw's command line options and a full paragraph of description for each of \*(sw's commands to standard output, and exits successfully. There's a lot of |
3315e8b3 |
459 | text generated by this option. I recommend you pipe it through a pager |
460 | so that you can actually read it. |
461 | .TP |
462 | .B "\-v, \-\-version" |
91f52355 |
463 | Writes \*(sw's version number to standard output and exits successfully. This is handy |
464 | when trying to decide whether your version of \*(sw has a particular feature, for example. |
3315e8b3 |
465 | .TP |
466 | .B "\-u, \-\-usage" |
467 | Writes a usage message so terse as to be nearly useless to standard |
468 | output and exits successfully. This is different from just running |
469 | .RB ` sw ' |
91f52355 |
470 | because although both print the same useless message, running \*(sw without any arguments is considered an error, so the message is sent to |
471 | standard error and \*(sw will exit unsuccessfully. |
3315e8b3 |
472 | .TP |
473 | .BI "\-a, \-\-arch " arch , arch\fR... |
474 | For commands which affect multiple architectures: only affect the |
475 | architectures specified. The architecture names may be separated by |
476 | commas, spaces or both, although clearly commas are most convenient on |
91f52355 |
477 | the command line. Architecture names may be abbreviated as long as the |
478 | abbreviation is not ambiguous. |
479 | .IP |
480 | This option overrides any other decisions that \*(sw might make about which architectures to process based on the |
481 | .B only\-arch |
3315e8b3 |
482 | list and the list of correctly built architectures for the current |
483 | package. |
484 | .TP |
485 | .B "\-f, \-\-force" |
486 | For commands which affect multiple architectures: affect even |
487 | architectures that have been successfully built. This has no effect if |
488 | there's a |
489 | .RB ` \-a ' |
490 | option in force. |
491 | .TP |
492 | .B "\-i, \-\-install" |
493 | For build commands: this is the final install step, so label architectures |
494 | which successfully complete it as having been completely built. It's |
495 | normal to specify this option on the |
496 | .RB ` "make install" ' |
497 | build command. |
498 | .TP |
499 | .BI "\-o, \-\-output " style |
500 | For build commands: select a style for the build output to be displayed |
501 | in. See the section |
502 | .B "Build commands" |
503 | for more details on output styles. |
504 | .TP |
505 | .B "\-b, \-\-beep" |
506 | For build commands: make a beep noise when the build finishes. This |
507 | provides a handy reminder if you're getting on with something else while |
1efab4fe |
508 | waiting for a long build. Use |
509 | .RB ` +b ' |
510 | or |
511 | .RB ` \-\-no\-beep ' |
512 | to turn this option off. This option is disabled by default, although |
513 | may be enabled in the |
514 | .B SW |
515 | environment variable. |
516 | .TP |
517 | .B "\-p, \-\percent" |
518 | For build commands: enable translation of |
519 | .RB ` % '-escape |
520 | sequences in command strings. These are described in more detail |
521 | in the section |
522 | .B "`%'-escape sequences" |
523 | below. Use |
524 | .RB ` +p ' |
525 | or |
526 | .RB ` --no-percent ' |
527 | to turn the option off. This option is enabled by default, although may |
528 | be disabled in the |
529 | .B SW |
530 | environment variable. |
3315e8b3 |
531 | .PP |
532 | The remaining options aren't really intended for users. They're helpful |
91f52355 |
533 | for \*(sw's own purposes, though, and described here for completeness' sake. They |
3315e8b3 |
534 | don't have standard Unix short name equivalents, because they're not |
535 | usually useful for users. |
536 | .TP |
537 | .B "\-\-archname" |
91f52355 |
538 | Writes the \*(sw architecture name of the current host to standard output. This is used |
539 | by \*(sw's configuration script to determine the current architecture name. This |
3315e8b3 |
540 | option is actually handled by a small shell script rather than by being |
541 | passed on to the main program. You shouldn't use this option yourself: |
542 | use the |
543 | .RB ` arch ' |
544 | command instead. Because this option is handled by the shell script, |
545 | and the script isn't very clever, you can't abbreviate |
546 | .B \-\-archname |
547 | on the command line, and it doesn't conflict with the similarly named |
548 | but completely different |
549 | .B \-\-arch |
550 | option, which you can still abbreviate all the way down to just |
551 | .RB ` \-\-a '. |
552 | .TP |
553 | .BI "\-\-me " name |
91f52355 |
554 | Sets \*(sw's idea of its program name to |
3315e8b3 |
555 | .IR name . |
91f52355 |
556 | This is intended for use by \*(sw's front-end shell script, but isn't |
557 | actually needed at the moment. I can't see why you'd want to play with |
558 | this option, but it shouldn't do any harm. |
3315e8b3 |
559 | .TP |
560 | .BI "\-\-remote " remote-command |
91f52355 |
561 | Used by \*(sw when running commands on remote hosts. Don't use this yourself: it puts \*(sw into a very unfriendly mode and requires that you communicate with it |
3315e8b3 |
562 | using a bizarre binary packet protocol. If you really must know more |
563 | about this, see the source code: it's quite well documented, really. |

569 | The descriptions below make use of some technical terms: |
570 | .TP |
571 | .B "architecture restriction" |
572 | A state created by the |
573 | .B only\-arch |
574 | command, restricting the |
575 | .I "default build architectures" |
576 | to those listed as arguments to the command. An architecture |
577 | restriction may be cleared by |
578 | .B all\-arch |
579 | command. |
580 | .TP |
581 | .B "build architectures" |
582 | The architectures which a |
583 | .I "build command" |
584 | will process. If the |
585 | .RB ` \-a ' |
586 | option is specified on the command line, then its argument specifies the |
587 | build architectures for this command; otherwise, the |
588 | .I "default build architectures" |
589 | are used. |
590 | .TP |
591 | .B "build command" |
592 | A command which executes a process on multiple hosts simultaneously and |
593 | reports the results. The processes executed usually perform some part |
594 | of the building of a package. Currently, the build commands are |
595 | .B run |
596 | and its derivatives |
597 | .B configure |
598 | and |
599 | .BR make . |
600 | .TP |
601 | .B "default build architectures" |
602 | The architectures which, in the absence of a |
603 | .RB ` \-a ' |
604 | command line option, are affected by a |
605 | .IR "build command" . |
91f52355 |
606 | To determine the default build architectures, \*(sw reads the list of all architectures from the |
3315e8b3 |
607 | .B archtab |
608 | file, and filters it: if the |
609 | .RB ` \-f ' |
610 | command line option is |
611 | .I not |
612 | specified, then architectures marked as |
613 | .I "successfully built" |
614 | are removed from the list; if there is an |
615 | .I "architecture restriction" |
616 | in force, then the list is further filtered according to the |
617 | restriction. |
618 | .TP |
619 | .B "successfully built" |
620 | A package is considered to be successfully built on a given architecture |
621 | if a build command given the |
622 | .RB ` \-i ' |
623 | command-line option succeeds on a host of that architecture. The list |
624 | of successfully built architectures can be cleared by the |
625 | .B reset |
626 | command. The |
627 | .RB ` \-f ' |
91f52355 |
628 | option causes \*(sw to ignore whether architectures have been successfully built when |
3315e8b3 |
629 | determining the |
630 | .IR "default build architectures" . |

656 | .PP |
4f71fd6c |
657 | \*(sw performs some checks before committing information to the index |
658 | file. Firstly, all the expected architectures must be successfully |
659 | built. Secondly, the script |
660 | .IB prefix /share/sw-precommit\fR |
661 | is run, if it exists. This script must exit successfully if the commit |
662 | is to proceed. The script can be configured to enforce local policy |
663 | requirements on installed software. |
664 | .PP |
665 | The |

720 | in the link tree will fetch the source files correctly, but place the |

949 | Output from a build command is presented in one of a number of named |

3315e8b3 |
951 | The style name |
952 | .RB ` plain ' |
953 | is always defined: it simply prefixes each line of output with the |
954 | name of the architecture which generated the line, which isn't actually |
955 | particularly easy to read. Other output styles may have been configured |
91f52355 |
956 | into \*(sw when it was compiled. |
3315e8b3 |
957 | .PP |
91f52355 |
958 | The set of output styles supported by \*(sw varies according to how it |
959 | was configured. In any particular \*(sw program, you might have some of |
960 | the following: |
3315e8b3 |
961 | .TP |
962 | .B plain |
963 | Simply prefixes each output line with the name of the architecture it |
964 | came from. This is quite hard to read, but it doesn't require any |
965 | special operating system support or clever terminal. |
966 | .TP |
967 | .B curses |
968 | Splits the terminal into independently scrolling areas, one for each |
969 | architecture, with a status line for each. Waits for a keypress when |
970 | all architectures are finished building. |
971 | .PP |
972 | The |
973 | .RB ` plain ' |
91f52355 |
974 | style is used when the selected style doesn't work (for example, you |
975 | don't have a sufficiently capable terminal for curses output). |
3315e8b3 |
976 | .PP |
977 | Output style names can be abbreviated as long as the abbreviation is |

1023 | This section describes how non-vendor software works at EBI. Chances |
1024 | are that other sites will work differently. This description is here as |
1025 | an example setup for \*(sw. |
1026 | .PP |
1027 | All the non-vendor software gets put in one big shared filesystem, and |
1028 | is exported from our main fileserver. The filesystem is mounted on all |
1029 | clients as |
1030 | .BR /sw/common . |
1031 | Architecture-neutral files are then |
1032 | placed in the conventional subdirectories off |
1033 | .B /sw/common |
1034 | (e.g., |
1035 | .BR /sw/common/share, |
1036 | or |
1037 | .BR /sw/common/info ). |
1038 | Architecture specific files are stored in subdirectories off |
1039 | .BR /sw/common/arch . |
1040 | For example, Linux binaries go in |
1041 | .BR /sw/common/arch/i386-linux/bin , |
1042 | and Solaris libraries in |
1043 | .BR /sw/common/arch/sparc-solaris/lib . |
1044 | Additionally, each architecture-specific subtree has a symbolic link |
1045 | back up to |
1046 | .B /sw/common |
1047 | for each of the architecture-neutral subdirectories. |
1048 | .PP |
1049 | There is a symbolic link on every client, from |
1050 | .B /sw/arch |
1051 | to |
1052 | .BI /sw/common/arch/ arch\fR, |
1053 | where |
1054 | .I arch |
1055 | is the architecture of that client. Thus, every client has two |
1056 | .I views |
1057 | of the software repository: the `common' view where every host sees |
1058 | exactly the same mapping between filenames and files, and the `arch' |
1059 | view where every host sees the same mapping between filenames and |
1060 | programs which do the same job. |
1061 | .PP |
1062 | And that's just about it. |

1071 | Contains a space-separated list of default command-line options. These |

1074 | .TP |
91f52355 |
1075 | .B SW_MAKE |
1076 | The name of the command to use to run a `make'. This is resolved on the |
1077 | local host once, rather than one for each build host, which is probably |
1078 | a misfeature. To do something more clever, point |
1079 | .B SW_MAKE |
1080 | at a shell script which then picks out the right architecture-specific |
1081 | .RB ` make ' |
1082 | program from the remote environment. |
1083 | .TP |
3315e8b3 |
1084 | .B SW_RSH |
1085 | The name of the remote-shell program to use. By default, something |
