If not, see . # make all to compile and build Emacs. # make install to install it (installs in-place, in `bin' subdir of top dir). # make TAGS to update tags tables. # # 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.)

Recompiling Lisp files # is BAD because lisp/Makefile.in requires a Unixy shell. boot := ifneq ($(wildcard msdos/autogen/Makefile.in),) ifeq ($(wildcard src/b-emacs.exe),) boot := b-emacs.exe endif endif # Subdirectories to run Make. `lisp' is not included because the # compiled lisp files are part of the distribution. (If we are # bootstrapping, the src target will run Make in `lisp' as well.) # leim is not included because it is part of the src target. all: lib lib-src src emacs misc lispref lispintro lib: FRC cd lib $(MAKE) top_srcdir=${top_srcdir} all cd .. lib-src: lib FRC cd lib-src $(MAKE) top_srcdir=${top_srcdir} all cd .. # Pass to src/Makefile.in an additional BOOTSTRAPEMACS variable which # is either set to b-emacs.exe (in case bootstrap-emacs has not been # constructed yet) or the empty string (otherwise). # src/Makefile.in uses it to implement conditional dependencies, so that # files that need bootstrap-emacs to be built do not additionally need # to be kept fresher than b-emacs.exe.
