| 6 | Building and Installing Emacs from CVS |
| 7 | |
| 8 | If this is the first time you go through it, you'll need to configure |
| 9 | before bootstrapping: |
| 10 | |
| 11 | $ ./configure |
| 12 | |
| 13 | Some of the files that are included in the Emacs tarball, such as |
| 14 | byte-compiled Lisp files, are not stored in the CVS repository. |
| 15 | Therefore, to build from CVS you must run "make bootstrap" |
| 16 | instead of just "make": |
| 17 | |
| 18 | $ cvs update -dP |
| 19 | $ make bootstrap |
| 20 | |
| 21 | Normally, it is not necessary to use "make bootstrap" after every CVS |
| 22 | update. "make" should work in 90% of the cases and be much quicker. |
| 23 | |
| 24 | $ make |
| 25 | |
| 26 | (If you want to install the Emacs binary, type "make install" instead |
| 27 | of "make" in the last command.) |
| 28 | |
| 29 | Occasionally the file "lisp/loaddefs.el" (and similar automatically |
| 30 | generated files, such as esh-groups.el, and *-loaddefs.el in some |
| 31 | subdirectories of lisp/, e.g. mh-e/ and calendar/) will need to be |
| 32 | updated to reflect new autoloaded functions. If you see errors (rather |
| 33 | than warnings) about undefined lisp functions during compilation, that |
| 34 | may be the reason. Another symptom may be an error saying that |
| 35 | "loaddefs.el" could not be found; this is due to a change in the way |
| 36 | loaddefs.el was handled in CVS, and should only happen once, for users |
| 37 | that are updating old CVS trees. Finally, sometimes there can be build |
| 38 | failures related to *loaddefs.el (e.g. "required feature `esh-groups' |
| 39 | was not provided"). In that case, follow the instructions below. |
| 40 | |
| 41 | To update loaddefs.el (and similar files), do: |
| 42 | |
| 43 | $ cd lisp |
| 44 | $ make autoloads |
| 45 | |
| 46 | If either of the above partial procedures fails, try "make bootstrap". |
| 47 | If CPU time is not an issue, the most thorough way to rebuild, and |
| 48 | avoid any spurious problems, is always to use this method. |
| 49 | |
| 50 | Users of non-Posix systems (MS-Windows etc.) should run the |
| 51 | platform-specific configuration scripts (nt/configure.bat, config.bat, |
| 52 | etc.) before "make bootstrap" or "make"; the rest of the procedure is |
| 53 | applicable to those systems as well. |
| 54 | |
| 55 | Questions, requests, and bug reports about the CVS versions of Emacs |
| 56 | should be sent to emacs-pretest-bug@gnu.org rather than gnu.emacs.help |
| 57 | or gnu.emacs.bug. Ideally, use M-x report-emacs-bug RET which will |
| 58 | send it to the proper place. |
| 59 | |
| 60 | Because the CVS version of Emacs is a work in progress, it will |
| 61 | sometimes fail to build. Please wait a day or so (and check the bug |
| 62 | and development mailing list archives) before reporting such problems. |
| 63 | In most cases, the problem is known about and is just waiting for |
| 64 | someone to fix it. |
| 65 | |
| 66 | |
| 67 | Note on using SSH to access the CVS repository from inside Emacs |
| 68 | ---------------------------------------------------------------- |
| 69 | |
| 70 | Write access to the CVS repository requires using SSH v2. |
| 71 | |
| 72 | If you execute cvs commands inside Emacs, specifically if you use |
| 73 | pcl-cvs, output from CVS may be lost due to a problem in the |
| 74 | interface between ssh, cvs, and libc. Corrupted checkins are |
| 75 | also known to have happened. |
| 76 | |
| 77 | To fix the problem, save the following script into a file, make it |
| 78 | executable, and set CVS_RSH to the file name of the script: |
| 79 | |
| 80 | #!/bin/bash |
| 81 | exec 2> >(exec cat >&2 2>/dev/null) |
| 82 | exec ssh "$@" |
| 83 | |
| 84 | This may be combined with the following entry in ~/.ssh/config to |
| 85 | simplify accessing the CVS repository: |
| 86 | |
| 87 | Host subversions.gnu.org |
| 88 | Protocol 2 |
| 89 | ForwardX11 no |
| 90 | User YOUR_USERID |
| 91 | |
