# make all to compile and build Emacs.

# make install to install it (installs in-place, in `bin' subdir of top dir).

|
#
|
|
# make clean or make mostlyclean
|
|
# Delete all files from the current directory that are normally
|
|
# created by building the program. Don't delete the files that
|
|
# record the configuration. Also preserve files that could be made
|
|
# by building, but normally aren't because the distribution comes
|
|
# with them.
|
|
#
|
|
# Delete `.dvi' files here if they are not part of the distribution.
|
|
#
|
|
# make distclean
|
|
# Delete all files from the current directory that are created by
|
|
# configuring or building the program. If you have unpacked the
|
|
# source and built the program without creating any other files,
|
|
# `make distclean' should leave only the files that were in the
|
|
# distribution.
|
|
#
|
|
# make maintainer-clean
|
|
# Delete everything from the current directory that can be
|
|
# reconstructed with this Makefile. This typically includes
|
|
# everything deleted by distclean, plus more: *.elc files,
|
|
# C source files produced by Bison, tags tables, info files,
|
|
# and so on.
|
|
#
|
|
# make extraclean
|
|
# Still more severe - delete backup and autosave files, too.

# This gork is required for those who use a Unix-style shell, and
|
|
# have SHELL in the environment pointing to it. Here we force
|
|
# Make to use COMMAND.COM instead. This Makefile won't work otherwise.
|
|
# (The /xyzzy directory is used to minimize the chance that someone
|
|
# actually has such a directory with an incompatible command.com. We
|
|
# used to have /dos there, but some Windows installations have an old
|
|
# version of DOS stashed in that directory, and command.com from there
|
|
# won't run on Windows, complaining about "Incorrect DOS version".
|
|
# Make will look up PATH for the shell executable, so the directory name
|
|
# is not important.)

# A: Only if we find msdos/autogen/Makefile.in, i.e. we are building out of
|
|
# a VCS-checkout (not a release), and src/b-emacs.exe does not exist.
|
|
# This avoids building a bootstrap-emacs and recompiling Lisp files
|
|
# when building a pretest/release tarball. Recompiling Lisp files
|
|
# is BAD because lisp/Makefile.in requires a Unixy shell.
