13 | Unpacking and Installation -- quick overview | |
14 | ========================== | |
15 | ||
aba7b4b6 | 16 | In this release, the GDB debugger sources, the generic GNU include |
c906108c SS |
17 | files, the BFD ("binary file description") library, the readline |
18 | library, and other libraries all have directories of their own | |
7072a954 | 19 | underneath the gdb-5.1.1 directory. The idea is that a variety of GNU |
c906108c SS |
20 | tools can share a common copy of these things. Be aware of variation |
21 | over time--for example don't try to build gdb with a copy of bfd from | |
34f47bc4 AC |
22 | a release other than the gdb release (such as a binutils release), |
23 | especially if the releases are more than a few weeks apart. | |
c906108c SS |
24 | Configuration scripts and makefiles exist to cruise up and down this |
25 | directory tree and automatically build all the pieces in the right | |
26 | order. | |
27 | ||
7072a954 AC |
28 | When you unpack the gdb-5.1.1.tar.gz file, you'll find a directory |
29 | called `gdb-5.1.1', which contains: | |

bec71058 | 41 | You can build GDB right in the source directory: |
c906108c | 42 | |
7072a954 | 43 | cd gdb-5.1.1 |
34f47bc4 AC |
44 | ./configure |
45 | make | |
46 | cp gdb/gdb /usr/local/bin/gdb (or wherever you want) | |
c906108c | 47 | |
bec71058 FN |
48 | However, we recommend that an empty directory be used instead. |
49 | This way you do not clutter your source tree with binary files | |
50 | and will be able to create different builds with different | |
51 | configuration options. | |
52 | ||
53 | You can build GDB in any empty build directory: | |
54 | ||
34f47bc4 AC |
55 | mkdir build |
56 | cd build | |
7072a954 | 57 | <full path to your sources>/gdb-5.1.1/configure |
34f47bc4 AC |
58 | make |
59 | cp gdb/gdb /usr/local/bin/gdb (or wherever you want) | |
bec71058 | 60 | |
c63ce875 | 61 | (Building GDB with DJGPP tools for MS-DOS/MS-Windows is slightly |
7072a954 | 62 | different; see the file gdb-5.1.1/gdb/config/djgpp/README for details.) |

64 | This will configure and build all the libraries as well as GDB. If |
65 | `configure' can't determine your system type, specify one as its | |
66 | argument, e.g., `./configure sun4' or `./configure decstation'. | |

68 | If you get compiler errors during this stage, see the `Reporting |
69 | Bugs' section below; there are a few known problems. | |

71 | GDB requires an ISO C (ANSI C) compiler. If you do not have an ISO |
72 | C compiler for your system, you may be able to download and install | |
73 | the GNU CC compiler. It is available via anonymous FTP from the | |
74 | directory `ftp://ftp.gnu.org/pub/gnu/gcc'. | |
c906108c | 75 | |
aba7b4b6 AC |
76 | GDB can be used as a cross-debugger, running on a machine of one |
77 | type while debugging a program running on a machine of another type. | |
78 | See below. | |

81 | More Documentation | |
82 | ****************** | |
83 | ||
84 | All the documentation for GDB comes as part of the machine-readable | |
aba7b4b6 AC |
85 | distribution. The documentation is written in Texinfo format, which |
86 | is a documentation system that uses a single source file to produce | |
87 | both on-line information and a printed manual. You can use one of the | |
88 | Info formatting commands to create the on-line version of the | |
89 | documentation and TeX (or `texi2roff') to typeset the printed version. | |
90 | ||
91 | GDB includes an already formatted copy of the on-line Info version | |
92 | of this manual in the `gdb/doc' subdirectory. The main Info file is | |
7072a954 | 93 | `gdb-5.1.1/gdb/doc/gdb.info', and it refers to subordinate files |
aba7b4b6 AC |
94 | matching `gdb.info*' in the same directory. If necessary, you can |
95 | print out these files, or read them with any editor; but they are | |
96 | easier to read using the `info' subsystem in GNU Emacs or the | |
97 | standalone `info' program, available as part of the GNU Texinfo | |
98 | distribution. | |
c906108c SS |
99 | |
100 | If you want to format these Info files yourself, you need one of the | |
101 | Info formatting programs, such as `texinfo-format-buffer' or | |
102 | `makeinfo'. | |
103 | ||
104 | If you have `makeinfo' installed, and are in the top level GDB | |
7072a954 | 105 | source directory (`gdb-5.1.1', in the case of version 5.1.1), you can make |
c906108c SS |
106 | the Info file by typing: |
107 | ||
34f47bc4 AC |
108 | cd gdb/doc |
109 | make info | |
c906108c SS |
110 | |
111 | If you want to typeset and print copies of this manual, you need | |
112 | TeX, a program to print its DVI output files, and `texinfo.tex', the | |
113 | Texinfo definitions file. This file is included in the GDB | |
7072a954 | 114 | distribution, in the directory `gdb-5.1.1/texinfo'. |
c906108c SS |
115 | |
116 | TeX is a typesetting program; it does not print files directly, but | |
117 | produces output files called DVI files. To print a typeset document, | |
118 | you need a program to print DVI files. If your system has TeX | |
119 | installed, chances are it has such a program. The precise command to | |
120 | use depends on your system; `lpr -d' is common; another (for PostScript | |
121 | devices) is `dvips'. The DVI print command may require a file name | |
122 | without any extension or a `.dvi' extension. | |
123 | ||
124 | TeX also requires a macro definitions file called `texinfo.tex'. | |
125 | This file tells TeX how to typeset a document written in Texinfo | |
126 | format. On its own, TeX cannot read, much less typeset a Texinfo file. | |
127 | `texinfo.tex' is distributed with GDB and is located in the | |
7072a954 | 128 | `gdb-5.1.1/texinfo' directory. |
c906108c SS |
129 | |
130 | If you have TeX and a DVI printer program installed, you can typeset | |
131 | and print this manual. First switch to the the `gdb' subdirectory of | |
7072a954 | 132 | the main source directory (for example, to `gdb-5.1.1/gdb') and then type: |
c906108c | 133 | |
34f47bc4 | 134 | make doc/gdb.dvi |
966beb0f EZ |
135 | |
136 | If you prefer to have the manual in PDF format, type this from the | |
137 | `gdb/doc' subdirectory of the main source directory: | |
138 | ||
34f47bc4 | 139 | make gdb.pdf |
966beb0f EZ |
140 | |
141 | For this to work, you will need the PDFTeX package to be installed. | |
c906108c SS |
142 | |
143 | ||
144 | Installing GDB | |
145 | ************** | |
146 | ||
147 | GDB comes with a `configure' script that automates the process of | |
148 | preparing GDB for installation; you can then use `make' to build the | |
149 | `gdb' program. | |
150 | ||
151 | The GDB distribution includes all the source code you need for GDB in | |
152 | a single directory, whose name is usually composed by appending the | |
153 | version number to `gdb'. | |
154 | ||
7072a954 | 155 | For example, the GDB version 5.1.1 distribution is in the `gdb-5.1.1' |
c906108c SS |
156 | directory. That directory contains: |
157 | ||
7072a954 | 158 | `gdb-5.1.1/{COPYING,COPYING.LIB}' |
c906108c SS |
159 | Standard GNU license files. Please read them. |

206 | Note: the following instructions are for building GDB on Unix or |
207 | Unix-like systems. Instructions for building with DJGPP for | |
208 | MS-DOS/MS-Windows are in the file gdb/config/djgpp/README. | |
c906108c SS |
209 | |
210 | The simplest way to configure and build GDB is to run `configure' | |
211 | from the `gdb-VERSION-NUMBER' source directory, which in this example | |
7072a954 | 212 | is the `gdb-5.1.1' directory. |
c906108c SS |
213 | |
214 | First switch to the `gdb-VERSION-NUMBER' source directory if you are | |
215 | not already in it; then run `configure'. | |
216 | ||
217 | For example: | |
218 | ||
7072a954 | 219 | cd gdb-5.1.1 |
34f47bc4 AC |
220 | ./configure |
221 | make | |
c906108c SS |
222 | |
223 | Running `configure' followed by `make' builds the `bfd', | |
224 | `readline', `mmalloc', and `libiberty' libraries, then `gdb' itself. | |
225 | The configured source files, and the binaries, are left in the | |
226 | corresponding source directories. | |
227 | ||
228 | `configure' is a Bourne-shell (`/bin/sh') script; if your system | |
229 | does not recognize this automatically when you run a different shell, | |
230 | you may need to run `sh' on it explicitly: | |
231 | ||
34f47bc4 | 232 | sh configure |
c906108c SS |
233 | |
234 | If you run `configure' from a directory that contains source | |
7072a954 AC |
235 | directories for multiple libraries or programs, such as the `gdb-5.1.1' |
236 | source directory for version 5.1.1, `configure' creates configuration | |
c906108c SS |
237 | files for every directory level underneath (unless you tell it not to, |
238 | with the `--norecursion' option). | |
239 | ||
240 | You can run the `configure' script from any of the subordinate | |
241 | directories in the GDB distribution, if you only want to configure that | |
242 | subdirectory; but be sure to specify a path to it. | |
243 | ||
7072a954 | 244 | For example, with version 5.1.1, type the following to configure only |
c906108c SS |
245 | the `bfd' subdirectory: |
246 | ||
7072a954 | 247 | cd gdb-5.1.1/bfd |
34f47bc4 | 248 | ../configure |
c906108c SS |
249 | |
250 | You can install `gdb' anywhere; it has no hardwired paths. However, | |
251 | you should make sure that the shell on your path (named by the `SHELL' | |
252 | environment variable) is publicly readable. Remember that GDB uses the | |
253 | shell to start your program--some systems refuse to let GDB debug child | |
254 | processes whose programs are not readable. | |
255 | ||
256 | ||
257 | Compiling GDB in another directory | |
258 | ================================== | |
259 | ||
260 | If you want to run GDB versions for several host or target machines, | |
261 | you need a different `gdb' compiled for each combination of host and | |
262 | target. `configure' is designed to make this easy by allowing you to | |
263 | generate each configuration in a separate subdirectory, rather than in | |
264 | the source directory. If your `make' program handles the `VPATH' | |
265 | feature correctly (GNU `make' and SunOS 'make' are two that should), | |
266 | running `make' in each of these directories builds the `gdb' program | |
267 | specified there. | |
268 | ||
269 | To build `gdb' in a separate directory, run `configure' with the | |
270 | `--srcdir' option to specify where to find the source. (You also need | |
271 | to specify a path to find `configure' itself from your working | |
272 | directory. If the path to `configure' would be the same as the | |
273 | argument to `--srcdir', you can leave out the `--srcdir' option; it | |
274 | will be assumed.) | |
275 | ||
7072a954 | 276 | For example, with version 5.1.1, you can build GDB in a separate |
c906108c SS |
277 | directory for a Sun 4 like this: |
278 | ||
7072a954 | 279 | cd gdb-5.1.1 |
c906108c SS |
280 | mkdir ../gdb-sun4 |
281 | cd ../gdb-sun4 | |
7072a954 | 282 | ../gdb-5.1.1/configure |
c906108c SS |
283 | make |
284 | ||
285 | When `configure' builds a configuration using a remote source | |
286 | directory, it creates a tree for the binaries with the same structure | |
287 | (and using the same names) as the tree under the source directory. In | |
288 | the example, you'd find the Sun 4 library `libiberty.a' in the | |
289 | directory `gdb-sun4/libiberty', and GDB itself in `gdb-sun4/gdb'. | |
290 | ||
291 | One popular reason to build several GDB configurations in separate | |
292 | directories is to configure GDB for cross-compiling (where GDB runs on | |
293 | one machine--the host--while debugging programs that run on another | |
294 | machine--the target). You specify a cross-debugging target by giving | |
295 | the `--target=TARGET' option to `configure'. | |
296 | ||
297 | When you run `make' to build a program or library, you must run it | |
298 | in a configured directory--whatever directory you were in when you | |
299 | called `configure' (or one of its subdirectories). | |
300 | ||
301 | The `Makefile' that `configure' generates in each source directory | |
302 | also runs recursively. If you type `make' in a source directory such | |
7072a954 AC |
303 | as `gdb-5.1.1' (or in a separate configured directory configured with |
304 | `--srcdir=PATH/gdb-5.1.1'), you will build all the required libraries, | |
c906108c SS |
305 | and then build GDB. |
306 | ||
307 | When you have multiple hosts or targets configured in separate | |
308 | directories, you can run `make' on them in parallel (for example, if | |
309 | they are NFS-mounted on each of the hosts); they will not interfere | |
310 | with each other. | |
311 | ||
312 | ||
313 | Specifying names for hosts and targets | |
314 | ====================================== | |
315 | ||
316 | The specifications used for hosts and targets in the `configure' | |
317 | script are based on a three-part naming scheme, but some short | |
318 | predefined aliases are also supported. The full naming scheme encodes | |
319 | three pieces of information in the following pattern: | |
320 | ||
321 | ARCHITECTURE-VENDOR-OS | |
322 | ||
323 | For example, you can use the alias `sun4' as a HOST argument or in a | |
324 | `--target=TARGET' option. The equivalent full name is | |
325 | `sparc-sun-sunos4'. | |
326 | ||
327 | The `configure' script accompanying GDB does not provide any query | |
328 | facility to list all supported host and target names or aliases. | |
329 | `configure' calls the Bourne shell script `config.sub' to map | |
330 | abbreviations to full names; you can read the script, if you wish, or | |
331 | you can use it to test your guesses on abbreviations--for example: | |
332 | ||
333 | % sh config.sub sun4 | |
334 | sparc-sun-sunos4.1.1 | |
335 | % sh config.sub sun3 | |
336 | m68k-sun-sunos4.1.1 | |
337 | % sh config.sub decstation | |
338 | mips-dec-ultrix4.2 | |
339 | % sh config.sub hp300bsd | |
340 | m68k-hp-bsd | |
341 | % sh config.sub i386v | |
342 | i386-pc-sysv | |
343 | % sh config.sub i786v | |
344 | Invalid configuration `i786v': machine `i786v' not recognized | |
345 | ||
346 | `config.sub' is also distributed in the GDB source directory | |
7072a954 | 347 | (`gdb-5.1.1', for version 5.1.1). |
c906108c SS |
348 | |
349 | ||
350 | `configure' options | |
351 | =================== | |
352 | ||
353 | Here is a summary of the `configure' options and arguments that are | |
354 | most often useful for building GDB. `configure' also has several other | |
355 | options not listed here. *note : (configure.info)What Configure Does, | |
356 | for a full explanation of `configure'. | |
357 | ||
358 | configure [--help] | |
359 | [--prefix=DIR] | |
360 | [--srcdir=PATH] | |
361 | [--norecursion] [--rm] | |
362 | [--enable-build-warnings] | |
363 | [--target=TARGET] | |
364 | [--host=HOST] | |
365 | [HOST] | |
366 | ||
367 | You may introduce options with a single `-' rather than `--' if you | |
368 | prefer; but you may abbreviate option names if you use `--'. | |
369 | ||
370 | `--help' | |
371 | Display a quick summary of how to invoke `configure'. | |
372 | ||
373 | `-prefix=DIR' | |
374 | Configure the source to install programs and files under directory | |
375 | `DIR'. | |
376 | ||
377 | `--srcdir=PATH' | |
378 | *Warning: using this option requires GNU `make', or another `make' | |
379 | that compatibly implements the `VPATH' feature.* | |
380 | Use this option to make configurations in directories separate | |
381 | from the GDB source directories. Among other things, you can use | |
382 | this to build (or maintain) several configurations simultaneously, | |
383 | in separate directories. `configure' writes configuration | |
384 | specific files in the current directory, but arranges for them to | |
385 | use the source in the directory PATH. `configure' will create | |
386 | directories under the working directory in parallel to the source | |
387 | directories below PATH. | |
388 | ||
389 | `--norecursion' | |
390 | Configure only the directory level where `configure' is executed; | |
391 | do not propagate configuration to subdirectories. | |
392 | ||
393 | `--rm' | |
394 | Remove the configuration that the other arguments specify. | |
395 | ||
396 | `--enable-build-warnings' | |
397 | When building the GDB sources, ask the compiler to warn about any | |
398 | code which looks even vaguely suspicious. You should only using | |
399 | this feature if you're compiling with GNU CC. It passes the | |

408 | |
409 | `--target=TARGET' | |
410 | Configure GDB for cross-debugging programs running on the specified | |
411 | TARGET. Without this option, GDB is configured to debug programs | |
412 | that run on the same machine (HOST) as GDB itself. | |
413 | ||
414 | There is no convenient way to generate a list of all available | |
415 | targets. | |
416 | ||
417 | `--host=HOST' | |
418 | Configure GDB to run on the specified HOST. | |
419 | ||
420 | There is no convenient way to generate a list of all available | |
421 | hosts. | |
422 | ||
423 | `HOST ...' | |
424 | Same as `--host=HOST'. If you omit this, GDB will guess; it's | |
425 | quite accurate. | |
426 | ||
427 | `configure' accepts other options, for compatibility with configuring | |
428 | other GNU tools recursively; but these are the only options that affect | |
429 | GDB or its supporting libraries. | |

432 | Remote debugging |
433 | ================= | |
434 | ||
aba7b4b6 AC |
435 | The files m68k-stub.c, i386-stub.c, and sparc-stub.c are examples |
436 | of remote stubs to be used with remote.c. They are designed to run | |
437 | standalone on an m68k, i386, or SPARC cpu and communicate properly | |
438 | with the remote.c stub over a serial line. | |
c906108c | 439 | |
aba7b4b6 | 440 | The directory gdb/gdbserver/ contains `gdbserver', a program that |
c906108c | 441 | allows remote debugging for Unix applications. gdbserver is only |
aba7b4b6 AC |
442 | supported for some native configurations, including Sun 3, Sun 4, and |
443 | Linux. | |
c906108c | 444 | |
aba7b4b6 | 445 | There are a number of remote interfaces for talking to existing ROM |
c906108c SS |
446 | monitors and other hardware: |
447 | ||
448 | remote-adapt.c AMD 29000 "Adapt" | |
449 | remote-array.c Array Tech RAID controller | |
450 | remote-bug.c Motorola BUG monitor | |
c906108c SS |
451 | remote-e7000.c Hitachi E7000 ICE |
452 | remote-eb.c AMD 29000 "EBMON" | |
453 | remote-es.c Ericsson 1800 monitor | |
454 | remote-est.c EST emulator | |
455 | remote-hms.c Hitachi Micro Systems H8/300 monitor | |
456 | remote-mips.c MIPS remote debugging protocol | |
457 | remote-mm.c AMD 29000 "minimon" | |
458 | remote-nindy.c Intel 960 "Nindy" | |
459 | remote-nrom.c NetROM ROM emulator | |
460 | remote-os9k.c PC running OS/9000 | |
461 | remote-rdi.c ARM with Angel monitor | |
462 | remote-rdp.c ARM with Demon monitor | |
463 | remote-sds.c PowerPC SDS monitor | |
464 | remote-sim.c Generalized simulator protocol | |
465 | remote-st.c Tandem ST-2000 monitor | |
466 | remote-udi.c AMD 29000 using the AMD "Universal Debug Interface" | |
467 | remote-vx.c VxWorks realtime kernel | |
468 | ||
aba7b4b6 AC |
469 | Remote-vx.c and the vx-share subdirectory contain a remote |
470 | interface for the VxWorks realtime kernel, which communicates over TCP | |
471 | using the Sun RPC library. This would be a useful starting point for | |
472 | other remote- via-ethernet back ends. | |
c906108c | 473 | |
aba7b4b6 AC |
474 | Remote-udi.c and the 29k-share subdirectory contain a remote |
475 | interface for AMD 29000 programs, which uses the AMD "Universal Debug | |
476 | Interface". This allows GDB to talk to software simulators, | |
477 | emulators, and/or bare hardware boards, via network or serial | |
478 | interfaces. Note that GDB only provides an interface that speaks UDI, | |
479 | not a complete solution. You will need something on the other end | |
480 | that also speaks UDI. | |

483 | Reporting Bugs | |
484 | =============== | |
485 | ||
aba7b4b6 AC |
486 | The correct address for reporting bugs found in gdb is |
487 | "bug-gdb@gnu.org". Please email all bugs, and all requests for help | |
488 | with GDB, to that address. Please include the GDB version number | |
7072a954 | 489 | (e.g., gdb-5.1.1), and how you configured it (e.g., "sun4" or "mach386 |
c906108c | 490 | host, i586-intel-synopsys target"). Since GDB now supports so many |
aba7b4b6 AC |
491 | different configurations, it is important that you be precise about |
492 | this. If at all possible, you should include the actual banner that | |
493 | GDB prints when it starts up, or failing that, the actual configure | |
494 | command that you used when configuring GDB. | |
c906108c | 495 | |
aba7b4b6 AC |
496 | For more information on how/whether to report bugs, see the GDB |
497 | Bugs section of the GDB manual (gdb/doc/gdb.texinfo) or the | |
498 | gdb/CONTRIBUTE file. | |

501 | Graphical interface to GDB -- X Windows, MS Windows | |
502 | ========================== | |
c906108c | 503 | |
aba7b4b6 AC |
504 | Several graphical interfaces to GDB are available. You should |
505 | check: | |

7072a954 | 507 | http://sourceware.cygnus.com/gdb/#gui |
c906108c | 508 | |
aba7b4b6 | 509 | for an up-to-date list. |
c906108c | 510 | |
aba7b4b6 | 511 | Emacs users will very likely enjoy the Grand Unified Debugger mode; |
f032fb6e | 512 | try typing `M-x gdb RET'. |

515 | Writing Code for GDB | |
516 | ===================== | |
517 | ||
aba7b4b6 | 518 | There is a lot of information about writing code for GDB in the |
c906108c SS |
519 | internals manual, distributed with GDB in gdb/doc/gdbint.texinfo. You |
520 | can read it by hand, print it by using TeX and texinfo, or process it | |
521 | into an `info' file for use with Emacs' info mode or the standalone | |
522 | `info' program. | |
523 | ||
aba7b4b6 | 524 | If you are pondering writing anything but a short patch, especially |
c906108c SS |
525 | take note of the information about copyrights in the node Submitting |
526 | Patches. It can take quite a while to get all the paperwork done, so | |
527 | we encourage you to start that process as soon as you decide you are | |
528 | planning to work on something, or at least well ahead of when you | |
529 | think you will be ready to submit the patches. | |
530 | ||
531 | ||
532 | GDB Testsuite | |
533 | ============= | |
534 | ||
aba7b4b6 AC |
535 | Included with the GDB distribution is a DejaGNU based testsuite |
536 | that can either be used to test your newly built GDB, or for | |
537 | regression testing a GDB with local modifications. | |
538 | ||
539 | Running the testsuite requires the prior installation of DejaGNU, | |
540 | which is generally available via ftp. The directory | |
7072a954 | 541 | ftp://sourceware.cygnus.com/pub/dejagnu/ will contain a recent |
aba7b4b6 AC |
542 | snapshot. Once DejaGNU is installed, you can run the tests in one of |
543 | the following ways: | |
c906108c | 544 | |
7072a954 | 545 | (1) cd gdb-5.1.1 |
aba7b4b6 AC |
546 | make check-gdb |
547 | ||
548 | or | |
c906108c | 549 | |
7072a954 | 550 | (2) cd gdb-5.1.1/gdb |
c906108c SS |
551 | make check |
552 | ||
553 | or | |
554 | ||
7072a954 | 555 | (3) cd gdb-5.1.1/gdb/testsuite |
c906108c SS |
556 | make site.exp (builds the site specific file) |
557 | runtest -tool gdb GDB=../gdb (or GDB=<somepath> as appropriate) | |
558 | ||
aba7b4b6 AC |
559 | The last method gives you slightly more control in case of problems |
560 | with building one or more test executables or if you are using the | |
561 | testsuite `standalone', without it being part of the GDB source tree. | |
c906108c SS |
