   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 autogen-clean
  45   $ make autoloads
  46
  47 If either of the above partial procedures fails, try "make bootstrap".
  48
  49 Very occasionally changes in the source can introduce
  50 incompatibilities with previous builds.  If a bootstrap fails, as a
  51 last resort try "make maintainer-clean" before configuring and
  52 bootstrapping again.  If CPU time is not an issue, the most thorough
  53 way to rebuild, and avoid any spurious problems, is always to use this
  54 method.
  55
  56 Users of non-Posix systems (MS-Windows etc.) should run the
  57 platform-specific configuration scripts (nt/configure.bat, config.bat,
  58 etc.) before "make bootstrap" or "make"; the rest of the procedure is
  59 applicable to those systems as well.
  60
  61 Questions, requests, and bug reports about the CVS versions of Emacs
  62 should be sent to emacs-pretest-bug@gnu.org rather than gnu.emacs.help
  63 or gnu.emacs.bug.  Ideally, use M-x report-emacs-bug RET which will
  64 send it to the proper place.
  65
  66 Because the CVS version of Emacs is a work in progress, it will
  67 sometimes fail to build.  Please wait a day or so (and check the bug
  68 and development mailing list archives) before reporting such problems.
  69 In most cases, the problem is known about and is just waiting for
  70 someone to fix it.

  73 Note on using SSH to access the CVS repository from inside Emacs
  74 ----------------------------------------------------------------
  75
  76 Write access to the CVS repository requires using SSH v2.
  77
  78 If you execute cvs commands inside Emacs, specifically if you use
  79 pcl-cvs, output from CVS may be lost due to a problem in the
  80 interface between ssh, cvs, and libc.  Corrupted checkins are
  81 also known to have happened.
  82
  83 To fix the problem, save the following script into a file, make it
  84 executable, and set CVS_RSH to the file name of the script:
  85
  86 #!/bin/bash
  87 exec 2> >(exec cat >&2 2>/dev/null)
  88 exec ssh "$@"
  89
  90 This may be combined with the following entry in ~/.ssh/config to
  91 simplify accessing the CVS repository:
  92
  93 Host subversions.gnu.org
  94      Protocol 2
  95      ForwardX11 no
  96      User YOUR_USERID
