  12 # http://www.gnu.org/software/emacs/manual/html_node/elisp/Building-Emacs.html#Building-Emacs
  13 # "Compilation of the C source files in the src directory produces an executable file called temacs, also called a
  14 # bare impure Emacs. It contains the Emacs Lisp interpreter and I/O routines, but not the editing commands.
  15 # The command temacs -l loadup would run temacs and direct it to load loadup.el. The loadup library loads additional Lisp libraries,
  16 # which set up the normal Emacs editing environment. After this step, the Emacs executable is no longer bare.
  17 # Because it takes some time to load the standard Lisp files, the temacs executable usually isn't run directly by users. Instead, as
  18 # one of the last steps of building Emacs, the command ‘temacs -batch -l loadup dump’ is run. The special ‘dump’ argument causes temacs
  19 # to dump out an executable program, called emacs, which has all the standard Lisp files preloaded. (The ‘-batch’ argument prevents
  20 # temacs from trying to initialize any of its data on the terminal, so that the tables of terminal information are empty in the dumped Emacs.)"

  22 ########## FROM src/Makefile:
  23 ## The dumped Emacs is as functional and more efficient than
  24 ## bootstrap-emacs, so we replace the latter with the former.
  25 ## Strictly speaking, emacs does not depend directly on all of $lisp,
  26 ## since not all pieces are used on all platforms.  But DOC depends
  27 ## on all of $lisp, and emacs depends on DOC, so it is ok to use $lisp here.
  28 # emacs$(EXEEXT): temacs$(EXEEXT) $(etc)/DOC $(lisp) $(leimdir)/leim-list.el
  29 # if test "$(CANNOT_DUMP)" = "yes"; then \
  30 #       rm -f emacs$(EXEEXT); \
  31 #       ln temacs$(EXEEXT) emacs$(EXEEXT); \
  32 # else \
  33 #       LC_ALL=C $(RUN_TEMACS) -batch -l loadup dump || exit 1; \
  34 #       test "X$(PAXCTL)" = X || $(PAXCTL) -zex emacs$(EXEEXT); \
  35 #       rm -f bootstrap-emacs$(EXEEXT); \
  36 #       ln emacs$(EXEEXT) bootstrap-emacs$(EXEEXT); \
  37 # fi
  38
  39 # so emacs => temacs, and then it tries to execute emacs, leading to error
  40
  41 # We can build without dump, but a bootstrap-emacs is still needed to produce bytecode-compiled (platform-independent) emacs lisp .elc files.
