| 13 | # http://www.gnu.org/software/emacs/manual/html_node/elisp/Building-Emacs.html#Building-Emacs |
| 14 | # "Compilation of the C source files in the src directory produces an executable file called temacs, also called a |
| 15 | # bare impure Emacs. It contains the Emacs Lisp interpreter and I/O routines, but not the editing commands. |
| 16 | # The command temacs -l loadup would run temacs and direct it to load loadup.el. The loadup library loads additional Lisp libraries, |
| 17 | # which set up the normal Emacs editing environment. After this step, the Emacs executable is no longer bare. |
| 18 | # Because it takes some time to load the standard Lisp files, the temacs executable usually isn't run directly by users. Instead, as |
| 19 | # one of the last steps of building Emacs, the command ‘temacs -batch -l loadup dump’ is run. The special ‘dump’ argument causes temacs |
| 20 | # to dump out an executable program, called emacs, which has all the standard Lisp files preloaded. (The ‘-batch’ argument prevents |
| 21 | # 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 | |
| 23 | ########## FROM src/Makefile: |
| 24 | ## The dumped Emacs is as functional and more efficient than |
| 25 | ## bootstrap-emacs, so we replace the latter with the former. |
| 26 | ## Strictly speaking, emacs does not depend directly on all of $lisp, |
| 27 | ## since not all pieces are used on all platforms. But DOC depends |
| 28 | ## on all of $lisp, and emacs depends on DOC, so it is ok to use $lisp here. |
| 29 | # emacs$(EXEEXT): temacs$(EXEEXT) $(etc)/DOC $(lisp) $(leimdir)/leim-list.el |
| 30 | # if test "$(CANNOT_DUMP)" = "yes"; then \ |
| 31 | # rm -f emacs$(EXEEXT); \ |
| 32 | # ln temacs$(EXEEXT) emacs$(EXEEXT); \ |
| 33 | # else \ |
| 34 | # LC_ALL=C $(RUN_TEMACS) -batch -l loadup dump || exit 1; \ |
| 35 | # test "X$(PAXCTL)" = X || $(PAXCTL) -zex emacs$(EXEEXT); \ |
| 36 | # rm -f bootstrap-emacs$(EXEEXT); \ |
| 37 | # ln emacs$(EXEEXT) bootstrap-emacs$(EXEEXT); \ |
| 38 | # fi |
| 39 | |
| 40 | # so emacs => temacs, and then it tries to execute emacs, leading to error |
| 41 | |
| 42 | # We can build without dump, but a bootstrap-emacs is still needed to produce bytecode-compiled (platform-independent) emacs lisp .elc files. |
