18 | ADDITIONAL DISTRIBUTION FILES |
19 | ||
20 | * leim-M.N.tar.gz | |
21 | ||
22 | The Emacs Lisp code for input methods for various international | |
23 | character scripts is distributed in a separate tar file because of its | |
24 | large size. This file is called leim-M.N.tar.gz, with the same | |
25 | version number as Emacs, and it unpacks into the directory | |
26 | emacs-M.N/leim. Thus, if you unpack it in the same directory where | |
27 | you unpacked the Emacs distribution, it fills in a subdirectory | |
28 | of the Emacs distribution. | |
29 | ||
30 | If you have already unpacked the Leim tar file into a subdirectory of | |
31 | the Emacs sources, building and installing Emacs automatically | |
32 | installs the input method support as well. If you unpack the Leim tar | |
33 | file into the Emacs sources after building and installing Emacs, just | |
34 | build Emacs again and install it again. | |
35 | ||
36 | * intlfonts-VERSION.tar.gz | |
37 | ||
38 | The intlfonts distribution contains X11 fonts that Emacs needs in | |
39 | order to display international characters. If you see a non-ASCII | |
40 | character appear as a hollow box, that means you don't have a font for | |
887af595 RS |
41 | it. You might find a font in the intlfonts distribution. If some |
42 | characters don't look right, or appear improperly aligned, a font | |
330a9ebb | 43 | from the intlfonts distribution might look better. |
887af595 RS |
44 | |
45 | The intlfonts distribution contains its own installation instructions, | |
46 | in the intlfonts/README file. | |

a0e671c7 | 49 | BUILDING AND INSTALLATION: |
00af31ec RS |
50 | |
51 | (This is for a Unix or Unix-like system. For MSDOS, see below; search | |
52 | for MSDOG. For Windows NT or Windows 95, see the file nt/INSTALL.) | |
a0e671c7 JB |
53 | |
54 | 1) Make sure your system has enough swapping space allocated to handle | |
55 | a program whose pure code is 900k bytes and whose data area is at | |
56 | least 400k and can reach 8Mb or more. If the swapping space is | |
57 | insufficient, you will get an error in the command `temacs -batch -l | |
bde335e3 | 58 | loadup dump', found in `./src/Makefile.in', or possibly when |
42db5687 | 59 | running the final dumped Emacs. |
a0e671c7 | 60 | |
2d475b5f KH |
61 | Building Emacs requires about 70 Mb of disk space (including the Emacs |
62 | sources). Once installed, Emacs occupies about 35 Mb in the file | |
42db5687 RS |
63 | system where it is installed; this includes the executable files, Lisp |
64 | libraries, miscellaneous data files, and on-line documentation. If | |
65 | the building and installation take place in different directories, | |
2d475b5f | 66 | then the installation procedure momentarily requires 70+35 Mb. |
a0e671c7 JB |
67 | |
68 | 2) Consult `./etc/MACHINES' to see what configuration name you should | |
f40423fa | 69 | give to the `configure' program. That file offers hints for |
a0e671c7 JB |
70 | getting around some possible installation problems. |
71 | ||
ea3165c7 RS |
72 | 3) You can build Emacs in the top-level Emacs source directory |
73 | or in a separate directory. | |
74 | ||
75 | 3a) To build in the top-level Emacs source directory, go to that | |
76 | directory and run the program `configure' as follows: | |
a0e671c7 | 77 | |
e4e772f1 | 78 | ./configure [CONFIGURATION-NAME] [--OPTION[=VALUE]] ... |
a0e671c7 JB |
79 | |
80 | The CONFIGURATION-NAME argument should be a configuration name given | |
e4e772f1 RS |
81 | in `./etc/MACHINES', with the system version number added at the end. |
82 | ||
83 | You should try first omitting CONFIGURATION-NAME. This way, | |
84 | `configure' will try to guess your system type. If it cannot guess, | |
85 | or if something goes wrong in building or installing Emacs this way, | |
86 | try again specifying the proper CONFIGURATION-NAME explicitly. | |
a0e671c7 | 87 | |
f40423fa DM |
88 | If you don't want X support, specify `--with-x=no'. If you omit this |
89 | option, `configure' will try to figure out for itself whether your | |
90 | system has X, and arrange to use it if present. | |
a0e671c7 JB |
91 | |
92 | The `--x-includes=DIR' and `--x-libraries=DIR' options tell the build | |
93 | process where the compiler should look for the include files and | |
f40423fa DM |
94 | object libraries used with the X Window System. Normally, `configure' |
95 | is able to find them; these options are necessary if you have your X | |
763b1847 KH |
96 | Window System files installed in unusual places. These options also |
97 | accept a list of directories, separated with colons. | |
a0e671c7 | 98 | |
f40423fa DM |
99 | To get more attractive menus, you can specify an X toolkit when you |
100 | configure Emacs; use the option `--with-x-toolkit=TOOLKIT', where | |
101 | TOOLKIT is `athena' or `motif' (`yes' and `lucid' are synonyms for | |
102 | `athena'). On some systems, it does not work to use a toolkit with | |
103 | shared libraries. | |
a0e671c7 JB |
104 | |
105 | The `--with-gcc' option specifies that the build process should | |
106 | compile Emacs using GCC. If you don't want to use GCC, specify | |
f40423fa DM |
107 | `--with-gcc=no'. If you omit this option, `configure' will search |
108 | for GCC in your path, and use it if present. | |
a0e671c7 | 109 | |
c5f329d6 RS |
110 | If you want the Emacs mail reader RMAIL to read mail from a POP |
111 | server, you must specify `--with-pop'. This provides support for the | |
112 | POP3 protocol; older versions are not supported. For | |
113 | Kerberos-authenticated POP add `--with-kerberos', for Hesiod support | |
114 | add `--with-hesiod'. These options enable Emacs to use POP; whether | |
115 | Emacs uses POP is controlled by individual users--see the Rmail | |
116 | chapter of the Emacs manual. | |
117 | ||
a0e671c7 JB |
118 | The `--prefix=PREFIXDIR' option specifies where the installation process |
119 | should put emacs and its data files. This defaults to `/usr/local'. | |
120 | - Emacs (and the other utilities users run) go in PREFIXDIR/bin | |
121 | (unless the `--exec-prefix' option says otherwise). | |
f40423fa DM |
122 | - The architecture-independent files go in PREFIXDIR/share/emacs/VERSION |
123 | (where VERSION is the version number of Emacs, like `19.27'). | |
a0e671c7 | 124 | - The architecture-dependent files go in |
f40423fa | 125 | PREFIXDIR/libexec/emacs/VERSION/CONFIGURATION |
a0e671c7 JB |
126 | (where CONFIGURATION is the configuration name, like mips-dec-ultrix4.2), |
127 | unless the `--exec-prefix' option says otherwise. | |
128 | ||
129 | The `--exec-prefix=EXECDIR' option allows you to specify a separate | |
130 | portion of the directory tree for installing architecture-specific | |
131 | files, like executables and utility programs. If specified, | |
132 | - Emacs (and the other utilities users run) go in EXECDIR/bin, and | |
133 | - The architecture-dependent files go in | |
f40423fa | 134 | EXECDIR/libexec/emacs/VERSION/CONFIGURATION. |
a0e671c7 JB |
135 | EXECDIR/bin should be a directory that is normally in users' PATHs. |
136 | ||
137 | For example, the command | |
138 | ||
139 | ./configure mips-dec-ultrix --with-x11 | |
140 | ||
141 | configures Emacs to build for a DECstation running Ultrix, with | |
142 | support for the X11 window system. | |
143 | ||
f40423fa | 144 | `configure' doesn't do any compilation or installation |
a0e671c7 | 145 | itself. It just creates the files that influence those things: |
908477d9 DM |
146 | `./Makefile', `lib-src/Makefile', `oldXMenu/Makefile', |
147 | `lwlib/Makefile', `src/Makefile', and `./src/config.h'. For details | |
148 | on exactly what it does, see the section called `CONFIGURATION BY | |
149 | HAND', below. | |
a0e671c7 JB |
150 | |
151 | When it is done, `configure' prints a description of what it did and | |
f40423fa DM |
152 | creates a shell script `config.status' which, when run, recreates the |
153 | same configuration. If `configure' exits with an error after | |
154 | disturbing the status quo, it removes `config.status'. `configure' | |
155 | also creates a file `config.cache' that saves the results of its tests | |
156 | to make reconfiguring faster, and a file `config.log' containing compiler | |
157 | output (useful mainly for debugging `configure'). You can give | |
158 | `configure' the option `--cache-file=FILE' to use the results of the | |
159 | tests in FILE instead of `config.cache'. Set FILE to `/dev/null' to | |
160 | disable caching, for debugging `configure'. | |
a0e671c7 JB |
161 | |
162 | The work of `configure' can be done by editing various files in the | |
ea3165c7 RS |
163 | distribution, but using `configure' is easier. See the section called |
164 | "CONFIGURATION BY HAND" below if you want to do the configuration | |
165 | yourself. | |
166 | ||
167 | 3b) To build in a separate directory, go to that directory | |
168 | and run the program `configure' as follows: | |
169 | ||
170 | SOURCE-DIR/configure CONFIGURATION-NAME [--OPTION[=VALUE]] ... | |
171 | ||
172 | SOURCE-DIR refers to the top-level Emacs source directory which is | |
173 | where Emacs's configure script is located. `configure' looks for the | |
174 | Emacs source code in the directory that `configure' is in. | |
175 | ||
176 | To build in a separate directory, you must use a version of `make' | |
177 | that supports the `VPATH' variable, such as GNU `make'. | |
a0e671c7 | 178 | |
793faff1 RS |
179 | 3c) Some people try to build in a separate directory by filling |
180 | it full of symlinks to the files in the real source directory. | |
e1655e2b RS |
181 | If you do that, `make all' does work, but `make install' fails: |
182 | it copies the symbolic links rather than the actual files. | |
183 | ||
184 | As far as is known, there is no particular reason to use | |
185 | a directory full of links rather than use the standard GNU | |
186 | facilities to build in a separate directory (see 3b above). | |
187 | ||
a0e671c7 | 188 | 4) Look at `./lisp/paths.el'; if some of those values are not right |
0b60f47d KH |
189 | for your system, set up the file `./lisp/site-init.el' with Emacs |
190 | Lisp code to override them; it is not a good idea to edit paths.el | |
a0e671c7 JB |
191 | itself. YOU MUST USE THE LISP FUNCTION `setq' TO ASSIGN VALUES, |
192 | rather than `defvar', as used by `./lisp/paths.el'. For example, | |
193 | ||
194 | (setq news-inews-program "/usr/bin/inews") | |
195 | ||
196 | is how you would override the default value of the variable | |
197 | news-inews-program (which is "/usr/local/inews"). | |
198 | ||
35b12ec0 RS |
199 | Before you override a variable this way, *look at the value* that the |
200 | variable gets by default! Make sure you know what kind of value the | |
201 | variable should have. If you don't pay attention to what you are | |
202 | doing, you'll make a mistake. | |
203 | ||
42db5687 RS |
204 | 5) Put into `./lisp/site-init.el' or `./lisp/site-load.el' any Emacs |
205 | Lisp code you want Emacs to load before it is dumped out. Use | |
206 | site-load.el for additional libraries if you arrange for their | |
207 | documentation strings to be in the etc/DOC file (see | |
bde335e3 | 208 | src/Makefile.in if you wish to figure out how to do that). For all |
8c10f3e4 RS |
209 | else, use site-init.el. Do not load byte-compiled code which |
210 | was build with a non-nil value of `byte-compile-dynamic'. | |
a0e671c7 | 211 | |
0d75540d RS |
212 | If you set load-path to a different value in site-init.el or |
213 | site-load.el, Emacs will use *precisely* that value when it starts up | |
214 | again. If you do this, you are on your own! | |
d07ee75a | 215 | |
a0e671c7 JB |
216 | Note that, on some systems, the code you place in site-init.el must |
217 | not use expand-file-name or any other function which may look | |
218 | something up in the system's password and user information database. | |
4fece393 | 219 | See `./etc/PROBLEMS' for more details on which systems this affects. |
a0e671c7 | 220 | |
eaa91904 RS |
221 | The `site-*.el' files are nonexistent in the distribution. You do not |
222 | need to create them if you have nothing to put in them. | |
a0e671c7 JB |
223 | |
224 | 6) Refer to the file `./etc/TERMS' for information on fields you may | |
225 | wish to add to various termcap entries. The files `./etc/termcap.ucb' | |
226 | and `./etc/termcap.dat' may already contain appropriately-modified | |
227 | entries. | |
228 | ||
229 | 7) Run `make' in the top directory of the Emacs distribution to finish | |
c5f48ce3 RS |
230 | building Emacs in the standard way. The final executable file is |
231 | named `src/emacs'. You can execute this file "in place" without | |
232 | copying it, if you wish; then it automatically uses the sibling | |
233 | directories ../lisp, ../lib-src, ../info. | |
234 | ||
235 | Or you can "install" the executable and the other Emacs into their | |
236 | installed locations, with `make install'. By default, Emacs's files | |
237 | are installed in the following directories: | |
a0e671c7 JB |
238 | |
239 | `/usr/local/bin' holds the executable programs users normally run - | |
c9da8016 RS |
240 | `emacs', `etags', `ctags', `b2m', `emacsclient', |
241 | and `rcs-checkin'. | |
a0e671c7 | 242 | |
f40423fa | 243 | `/usr/local/share/emacs/VERSION/lisp' holds the Emacs Lisp library; |
a0e671c7 | 244 | `VERSION' stands for the number of the Emacs version |
f40423fa | 245 | you are installing, like `18.59' or `19.27'. Since the |
cdb49480 | 246 | Lisp library changes from one version of Emacs to |
a0e671c7 JB |
247 | another, including the version number in the path |
248 | allows you to have several versions of Emacs installed | |
cdb49480 RS |
249 | at the same time; in particular, you don't have to |
250 | make Emacs unavailable while installing a new version. | |
a0e671c7 | 251 | |
cdb49480 RS |
252 | `/usr/local/share/emacs/VERSION/site-lisp' holds the local Emacs Lisp |
253 | files installed for Emacs version VERSION only. | |
254 | ||
255 | `/usr/local/share/emacs/site-lisp' holds the local Emacs Lisp | |
256 | files installed for all Emacs versions. | |
257 | ||
258 | When Emacs is installed, it searches for its Lisp files | |
259 | in `/usr/local/share/emacs/VERSION/site-lisp', then in | |
260 | `/usr/local/share/emacs/site-lisp', and finally in | |
261 | `/usr/local/share/emacs/VERSION/lisp'. | |
a0e671c7 | 262 | |
f40423fa | 263 | `/usr/local/share/emacs/VERSION/etc' holds the Emacs tutorial, the DOC |
a0e671c7 JB |
264 | file, the `yow' database, and other |
265 | architecture-independent files Emacs might need while | |
266 | running. VERSION is as specified for `.../lisp'. | |
267 | ||
f40423fa | 268 | `/usr/local/libexec/emacs/VERSION/CONFIGURATION-NAME' contains executable |
a0e671c7 JB |
269 | programs used by Emacs that users are not expected to |
270 | run themselves. | |
271 | `VERSION' is the number of the Emacs version you are | |
272 | installing, and `CONFIGURATION-NAME' is the argument | |
273 | you gave to the `configure' program to identify the | |
274 | architecture and operating system of your machine, | |
275 | like `mips-dec-ultrix' or `sparc-sun-sunos'. Since | |
276 | these files are specific to the version of Emacs, | |
277 | operating system, and architecture in use, including | |
278 | the configuration name in the path allows you to have | |
279 | several versions of Emacs for any mix of machines and | |
280 | operating systems installed at the same time; this is | |
281 | useful for sites at which different kinds of machines | |
282 | share the file system Emacs is installed on. | |
283 | ||
284 | `/usr/local/info' holds the on-line documentation for Emacs, known as | |
285 | "info files". Many other GNU programs are documented | |
286 | using info files as well, so this directory stands | |
287 | apart from the other, Emacs-specific directories. | |
288 | ||
289 | `/usr/local/man/man1' holds the man pages for the programs installed | |
290 | in `/usr/local/bin'. | |
291 | ||
292 | If these directories are not what you want, you can specify where to | |
293 | install Emacs's libraries and data files or where Emacs should search | |
cdb49480 | 294 | for its Lisp files by giving values for `make' variables as part of |
a0e671c7 JB |
295 | the command. See the section below called `MAKE VARIABLES' for more |
296 | information on this. | |
297 | ||
298 | 8) Check the file `dir' in your site's info directory (usually | |
299 | /usr/local/info) to make sure that it has a menu entry for the Emacs | |
300 | info files. | |
301 | ||
42db5687 | 302 | 9) If your system uses lock files to interlock access to mailer inbox files, |
f40423fa | 303 | then you might need to make the movemail program setuid or setgid |
42db5687 RS |
304 | to enable it to write the lock files. We believe this is safe. |
305 | ||
2d475b5f KH |
306 | 10) You are done! You can remove executables and object files from |
307 | the build directory by typing `make clean'. To also remove the files | |
308 | that `configure' created (so you can compile Emacs for a different | |
309 | configuration), type `make distclean'. | |
310 | ||
a0e671c7 JB |
311 | |
312 | ||
313 | MAKE VARIABLES | |
314 | ||
315 | You can change where the build process installs Emacs and its data | |
316 | files by specifying values for `make' variables as part of the `make' | |
317 | command line. For example, if you type | |
318 | ||
319 | make install bindir=/usr/local/gnubin | |
320 | ||
321 | the `bindir=/usr/local/gnubin' argument indicates that the Emacs | |
322 | executable files should go in `/usr/local/gnubin', not | |
323 | `/usr/local/bin'. | |
324 | ||
325 | Here is a complete list of the variables you may want to set. | |
326 | ||
327 | `bindir' indicates where to put executable programs that users can | |
328 | run. This defaults to /usr/local/bin. | |
329 | ||
330 | `datadir' indicates where to put the architecture-independent | |
331 | read-only data files that Emacs refers to while it runs; it | |
908477d9 | 332 | defaults to /usr/local/share. We create the following |
a0e671c7 | 333 | subdirectories under `datadir': |
cdb49480 | 334 | - `emacs/VERSION/lisp', containing the Emacs Lisp library, and |
a0e671c7 JB |
335 | - `emacs/VERSION/etc', containing the Emacs tutorial, the DOC |
336 | file, and the `yow' database. | |
337 | `VERSION' is the number of the Emacs version you are installing, | |
338 | like `18.59' or `19.0'. Since these files vary from one version | |
339 | of Emacs to another, including the version number in the path | |
340 | allows you to have several versions of Emacs installed at the | |
341 | same time; this means that you don't have to make Emacs | |
342 | unavailable while installing a new version. | |
343 | ||
908477d9 DM |
344 | `libexecdir' indicates where to put architecture-specific data files that |
345 | Emacs refers to as it runs; it defaults to `/usr/local/libexec'. | |
346 | We create the following subdirectories under `libexecdir': | |
a0e671c7 JB |
347 | - `emacs/VERSION/CONFIGURATION-NAME', containing executable |
348 | programs used by Emacs that users are not expected to run | |
349 | themselves. | |
350 | `VERSION' is the number of the Emacs version you are installing, | |
351 | and `CONFIGURATION-NAME' is the argument you gave to the | |
352 | `configure' program to identify the architecture and operating | |
353 | system of your machine, like `mips-dec-ultrix' or | |
354 | `sparc-sun-sunos'. Since these files are specific to the version | |
355 | of Emacs, operating system, and architecture in use, including | |
356 | the configuration name in the path allows you to have several | |
357 | versions of Emacs for any mix of machines and operating systems | |
358 | installed at the same time; this is useful for sites at which | |
359 | different kinds of machines share the file system Emacs is | |
360 | installed on. | |
361 | ||
362 | `infodir' indicates where to put the info files distributed with | |
363 | Emacs; it defaults to `/usr/local/info'. | |
364 | ||
365 | `mandir' indicates where to put the man pages for Emacs and its | |
366 | utilities (like `etags'); it defaults to | |
367 | `/usr/local/man/man1'. | |
368 | ||
369 | `manext' gives the extension the man pages should be installed with. | |
370 | It should contain a period, followed by the appropriate | |
371 | digit. It defaults to `.1'. For example given the default | |
372 | values for `mandir' and `manext', the Emacs man page would be | |
373 | installed as `/usr/local/man/man1/emacs.1'. | |
374 | ||
375 | `prefix' doesn't give a path for any specific part of Emacs; instead, | |
376 | its value is used to determine the defaults for all the | |
377 | architecture-independent path variables - `datadir', | |
908477d9 | 378 | `sharedstatedir', `infodir', and `mandir'. Its default value is |
a0e671c7 JB |
379 | `/usr/local'; the other variables add on `lib' or `man' to it |
380 | by default. | |
381 | ||
382 | For example, suppose your site generally places GNU software | |
383 | under `/usr/users/software/gnusoft' instead of `/usr/local'. | |
384 | By including | |
385 | `prefix=/usr/users/software/gnusoft' | |
386 | in the arguments to `make', you can instruct the build process | |
387 | to place all of the Emacs data files in the appropriate | |
388 | directories under that path. | |
389 | ||
390 | `exec_prefix' serves the same purpose as `prefix', but instead | |
391 | determines the default values for the architecture-dependent | |
908477d9 | 392 | path variables - `bindir' and `libexecdir'. |
a0e671c7 JB |
393 | |
394 | The above variables serve analogous purposes in the makefiles for all | |
5c462624 | 395 | GNU software; this variable is specific to Emacs. |
a0e671c7 | 396 | |
2d475b5f KH |
397 | `archlibdir' indicates where Emacs installs and expects the executable |
398 | files and other architecture-dependent data it uses while | |
399 | running. Its default value, based on `libexecdir' (which | |
400 | see), is `/usr/local/libexec/emacs/VERSION/CONFIGURATION-NAME' | |
a0e671c7 JB |
401 | (where VERSION and CONFIGURATION-NAME are as described above). |
402 | ||
403 | Remember that you must specify any variable values you need each time | |
404 | you run `make' in the top directory. If you run `make' once to build | |
405 | emacs, test it, and then run `make' again to install the files, you | |
406 | must provide the same variable settings each time. To make the | |
407 | settings persist, you can edit them into the `Makefile' in the top | |
408 | directory, but be aware that running the `configure' program erases | |
409 | `Makefile' and rebuilds it from `Makefile.in'. | |
410 | ||
5c462624 RS |
411 | The path for finding Lisp files is specified in src/paths.h, |
412 | a file which is generated by running configure. To change the path, | |
413 | you can edit the definition of PATH_LOADSEARCH in that file | |
414 | before you run `make'. | |
415 | ||
a0e671c7 JB |
416 | The top-level Makefile stores the variable settings it used in the |
417 | Makefiles for the subdirectories, so you don't have to specify them | |
418 | when running make in the subdirectories. | |
419 | ||
420 | ||
421 | CONFIGURATION BY HAND | |
422 | ||
c9da8016 RS |
423 | Instead of running the `configure' program, you have to perform the |
424 | following steps. | |
a0e671c7 | 425 | |
bde335e3 | 426 | 1) Copy `./src/config.in' to `./src/config.h'. |
a0e671c7 JB |
427 | |
428 | 2) Consult `./etc/MACHINES' to see what configuration name you should | |
429 | use for your system. Look at the code of the `configure' script to | |
430 | see which operating system and architecture description files from | |
431 | `src/s' and `src/m' should be used for that configuration name. Edit | |
432 | `src/config.h', and change the two `#include' directives to include | |
433 | the appropriate system and architecture description files. | |
434 | ||
435 | 2) Edit `./src/config.h' to set the right options for your system. If | |
436 | you need to override any of the definitions in the s/*.h and m/*.h | |
437 | files for your system and machine, do so by editing config.h, not by | |
438 | changing the s/*.h and m/*.h files. Occasionally you may need to | |
439 | redefine parameters used in `./lib-src/movemail.c'. | |
440 | ||
c9da8016 | 441 | 3) Create src/Makefile and lib-src/Makefile from the corresponding |
bde335e3 | 442 | `Makefile.in' files. First copy `Makefile.in' to `Makefile.c', |
94684a2e | 443 | then edit in appropriate substitutions for the @...@ constructs, |
c9da8016 RS |
444 | and then copy the shell commands near the end of `configure' |
445 | that run cpp to construct `Makefile'. | |
a0e671c7 | 446 | |
c9da8016 RS |
447 | 4) Create `Makefile' files in various other directories |
448 | from the corresponding `Makefile.in' files. This isn't so hard, | |
449 | just a matter of substitution. | |
a0e671c7 | 450 | |
a0e671c7 | 451 | The `configure' script is built from `configure.in' by the `autoconf' |
f40423fa | 452 | program. You need version 2.0 or newer of `autoconf' to rebuild `configure'. |
a0e671c7 JB |
453 | |
454 | BUILDING GNU EMACS BY HAND | |
455 | ||
a4af02f3 RS |
456 | Once Emacs is configured, running `make' in the top directory performs |
457 | the following steps. | |
a0e671c7 JB |
458 | |
459 | 1) Run `make src/paths.h' in the top directory. This produces | |
bde335e3 | 460 | `./src/paths.h' from the template file `./src/paths.in', changing |
a0e671c7 JB |
461 | the paths to the values specified in `./Makefile'. |
462 | ||
c9da8016 RS |
463 | 2) Go to directory `./lib-src' and run `make'. This creates |
464 | executables named `ctags' and `etags' and `wakeup' and `make-docfile' | |
465 | and `digest-doc' and `test-distrib'. And others. | |
a0e671c7 | 466 | |
c9da8016 RS |
467 | 3) Go to directory `./src' and Run `make'. This refers to files in |
468 | the `./lisp' and `./lib-src' subdirectories using names `../lisp' and | |
a0e671c7 JB |
469 | `../lib-src'. |
470 | ||
471 | This creates a file `./src/emacs' which is the runnable Emacs, | |
c9da8016 RS |
472 | which has another name that contains a version number. |
473 | Each time you do this, that version number increments in the last place. | |
a0e671c7 JB |
474 | |
475 | It also creates a file in `./etc' whose name is `DOC' followed by the | |
476 | current Emacs version. This file contains documentation strings for | |
477 | all the functions in Emacs. Each time you run make to make a new | |
478 | emacs, a new DOC file with a new name is made. You must keep the DOC | |
479 | file for an Emacs version as long as you keep using that Emacs | |
480 | version. | |
481 | ||
482 | ||
483 | INSTALLATION BY HAND | |
484 | ||
a4af02f3 RS |
485 | The steps below are done by running `make install' in the main |
486 | directory of the Emacs distribution. | |
a0e671c7 JB |
487 | |
488 | 1) Copy `./lisp' and its subdirectories, `./etc', and the executables | |
489 | in `./lib-src' to their final destinations, as selected in `./src/paths.h'. | |
490 | ||
491 | Strictly speaking, not all of the executables in `./lib-src' need be copied. | |
eaa91904 | 492 | - The programs `cvtmail', `emacsserver', `fakemail', `hexl', |
c9da8016 RS |
493 | `movemail', `profile', `rcs2log', `timer', `vcdiff', `wakeup', |
494 | and `yow' are used by Emacs; they do need to be copied. | |
495 | - The programs `etags', `ctags', `emacsclient', `b2m', and `rcs-checkin' | |
a0e671c7 | 496 | are intended to be run by users; they are handled below. |
3ae888e8 | 497 | - The programs `make-docfile' and `test-distrib' were |
a0e671c7 JB |
498 | used in building Emacs, and are not needed any more. |
499 | - The programs `digest-doc' and `sorted-doc' convert a `DOC' file into | |
500 | a file for users to read. There is no important reason to move them. | |
501 | ||
502 | 2) Copy the files in `./info' to the place specified in | |
503 | `./lisp/site-init.el' or `./lisp/paths.el'. Note that if the | |
504 | destination directory already contains a file named `dir', you | |
505 | probably don't want to replace it with the `dir' file in the Emacs | |
506 | distribution. Instead, you should make sure that the existing `dir' | |
507 | file contains an appropriate menu entry for the Emacs info. | |
508 | ||
100b770b | 509 | 3) Copy `./src/emacs' to `/usr/local/bin', or to some other directory |
a0e671c7 JB |
510 | in users' search paths. `./src/emacs' has an alternate name |
511 | `./src/emacs-EMACSVERSION'; you may wish to make a symbolic link named | |
512 | `/usr/local/bin/emacs' pointing to that alternate name, as an easy way | |
513 | of installing different versions. | |
514 | ||
515 | You can delete `./src/temacs'. | |
516 | ||
100b770b | 517 | 4) Copy the programs `b2m', `emacsclient', `ctags', `etags', and |
c9da8016 | 518 | `rcs-checkin' from `./lib-src' to `/usr/local/bin'. These programs are |
a0e671c7 JB |
519 | intended for users to run. |
520 | ||
100b770b | 521 | 5) Copy the man pages in `./etc' for emacs, ctags, and etags into the |
a0e671c7 JB |
522 | appropriate man directories. |
523 | ||
100b770b | 524 | 6) The files in the `./src' subdirectory, except for `emacs', are not |
c9da8016 RS |
525 | used by Emacs once it is built. However, it is very desirable to keep |
526 | the source on line for debugging. | |

532 | problems sometimes encountered, and what to do about them. |

535 | Installation on MSDOG (a.k.a. MSDOS) |
536 | ||
eaa91904 | 537 | To install on MSDOG, you need to have the GNU C compiler for MSDOG |
3f0ec1b7 RS |
538 | (also known as djgpp), GNU Make, rm, mv, and sed. See the remarks in |
539 | config.bat for more information about locations and versions. The | |
540 | file etc/FAQ includes pointers to Internet sites where you can find | |
541 | the necessary utilities; search for "MS-DOS". The configuration step | |
542 | (see below) will test for these utilities and will refuse to continue | |
543 | if any of them isn't found. | |
544 | ||
545 | If you are building the MSDOG version of Emacs on an MSDOG-like system | |
546 | which supports long file names (e.g. Windows 95), you need to make | |
547 | sure that long file names are handled consistently both when you | |
548 | unpack the distribution and compile it. If you intend to compile with | |
549 | DJGPP v2.0 or later, and long file names support is enabled (LFN=y in | |
550 | the environment), you need to unpack Emacs distribution in a way that | |
551 | doesn't truncate the original long filenames to the DOS 8.3 namespace; | |
552 | the easiest way to do this is to use djtar program which comes with | |
553 | DJGPP, since it will note the LFN setting and behave accordingly. | |
554 | DJGPP v1 doesn't support long filenames, so you must unpack Emacs with | |
555 | a program that truncates the filenames to 8.3 naming as it extracts | |
556 | files; again, using djtar after setting LFN=n is the recommended way. | |
557 | You can build Emacs with LFN=n even if you use DJGPP v2, if some of | |
558 | your tools don't support long file names: just ensure that LFN is set | |
559 | to `n' during both unpacking and compiling. | |
560 | ||
561 | (By the time you read this, you have already unpacked the Emacs | |
562 | distribution, but if the explanations above imply that you should have | |
563 | done it differently, it's safer to delete the directory tree created | |
564 | by the unpacking program and unpack Emacs again, than to risk running | |
565 | into problems during the build process.) | |
566 | ||
567 | It is important to understand that the runtime support of long file | |
568 | names by the Emacs binary is NOT affected by the LFN setting during | |
569 | compilation; Emacs compiled with DJGPP v2.0 or later will always | |
570 | support long file names on Windows 95 no matter what was the setting | |
e60ea278 KH |
571 | of LFN at compile time. However, if you compiled with LFN disabled |
572 | and want to enable LFN support after Emacs was already built, you need | |
573 | to make sure that the support files in the lisp, etc and info | |
574 | directories are called by their original long names as found in the | |
575 | distribution. You can do this either by renaming the files manually, | |
576 | or by extracting them from the original distribution archive with | |
577 | djtar after you set LFN=y in the environment. | |
3f0ec1b7 RS |
578 | |
579 | To unpack Emacs with djtar, type this command: | |
580 | ||
581 | djtar -x emacs.tgz | |
582 | ||
583 | (This assumes that the Emacs distribution is called `emacs.tgz' on | |
e2726984 | 584 | your system.) |
3f0ec1b7 RS |
585 | |
586 | When unpacking is done, a directory called `emacs-XX.YY' will be | |
587 | created, where XX.YY is the Emacs version. To build and install | |
588 | Emacs, chdir to that directory and type these commands: | |
0287f07c RS |
589 | |
590 | config msdos | |
591 | make install | |
42db5687 | 592 | |
db50afc0 RS |
593 | Building Emacs creates executable files in the src and lib-src |
594 | directories. Installing Emacs on MSDOS moves these executables to a | |
595 | sibling directory called bin. For example, if you build in directory | |
596 | /emacs, installing moves the executables from /emacs/src and | |
597 | /emacs/lib-src to the directory /emacs/bin, so you can then delete the | |
598 | subdirectories /emacs/src and /emacs/lib-src if you wish. The only | |
3f0ec1b7 RS |
599 | subdirectories you need to keep are bin, lisp, etc and info. The bin |
600 | subdirectory should be added to your PATH. The msdos subdirectory | |
601 | includes a PIF and an icon file for Emacs which you might find useful | |
602 | if you run Emacs under MS Windows. | |
db50afc0 RS |
603 | |
604 | Emacs on MSDOS finds the lisp, etc and info directories by looking in | |
605 | ../lisp, ../etc and ../info, starting from the directory where the | |
606 | Emacs executable was run from. You can override this by setting the | |
e2726984 RS |
607 | environment variables EMACSDATA (for the location of `etc' directory), |
608 | EMACSLOADPATH (for the location of `lisp' directory) and INFOPATH (for | |
609 | the location of the `info' directory). | |
42db5687 | 610 | |
eaa91904 RS |
611 | MSDOG is a not a multitasking operating system, so Emacs features such |
612 | as asynchronous subprocesses that depend on multitasking will not | |
613 | work. Synchronous subprocesses do work. | |
d536be4a | 614 | |
22609647 RS |
615 | Version 2.0 of djgpp has two bugs that affect Emacs. We've included |
616 | corrected versions of two files from djgpp in the msdos subdirectory: | |
617 | is_exec.c and sigaction.c. To work around the bugs, compile these | |
618 | files and link them into temacs. Djgpp version 2.01 have these bugs | |
619 | fixed, so upgrade if you can before building Emacs. |
