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