GNU Emacs Installation Guide for the DJGPP (a.k.a. MS-DOS) port
|
||
|
||
Copyright (C) 1992, 1994, 1996-1997, 2000-2014 Free Software Foundation,
|
||
Inc.
|
||
See the end of the file for license conditions.
|
||
|
||
The DJGPP port of GNU Emacs builds and runs on all versions of
|
||
MS-Windows from version 3.X on, including Windows XP, Vista, and
|
||
Windows 7 (however, see below for issues with Windows Vista and 7).
|
||
Building on plain MS-DOS is supported only if long file names are
|
||
supported (e.g., with a specialized driver such as doslfn).
|
||
|
||
To build and install the DJGPP port, you need to have the DJGPP ports
|
||
of GCC (the GNU C compiler), GNU Make, rm, mv, cp, and sed. See the
|
||
remarks in CONFIG.BAT for more information about locations and
|
||
versions. The Emacs FAQ (see info/efaq.info) includes pointers to
|
||
Internet sites where you can find the necessary utilities; search for
|
||
"MS-DOS". The configuration step (see below) will test for these
|
||
utilities and will refuse to continue if any of them isn't found.
|
||
|
||
Bootstrapping Emacs or recompiling Lisp files in the `lisp'
|
||
subdirectory using the various targets in the lisp/Makefile file
|
||
requires additional utilities: `find' (from Findutils), GNU `echo' and
|
||
`test' (from Sh-utils or Coreutils), `ls' and `chmod' (from Fileutils
|
||
or Coreutils), `grep' (from Grep), and a port of Bash. However, you
|
||
should not normally need to run lisp/Makefile, as all the Lisp files
|
||
are distributed in byte-compiled form as well. As for bootstrapping
|
||
itself, you will only need that if you check-out development sources
|
||
from the Emacs source repository.
|
||
|
||
Building the DJGPP version of Emacs is currently supported only on
|
||
systems which support long file names (e.g. Windows 9X or Windows XP).
|
||
You need to unpack Emacs distribution in a way that doesn't truncate
|
||
the original long filenames to the DOS 8.3 namespace; the easiest way
|
||
to do this is to use djtar program which comes with DJGPP, since it
|
||
will behave consistently with the rest of DJGPP tools. Do _not_
|
||
disable the DJGPP long-file-name support (a.k.a. "LFN") while building
|
||
Emacs.
|
||
|
||
(By the time you read this, you have already unpacked the Emacs
|
||
distribution, but if the explanations above imply that you should have
|
||
done it differently, it's safer to delete the directory tree created
|
||
by the unpacking program and unpack Emacs again, than to risk running
|
||
into strange problems during the build process.)
|
||
|
||
To unpack Emacs with djtar, type this command:
|
||
|
||
djtar -x emacs.tgz
|
||
|
||
(This assumes that the Emacs distribution is called `emacs.tgz' on
|
||
your system.)
|
||
|
||
When unpacking Emacs is done, a directory called `emacs-XX.YY' will be
|
||
created, where XX.YY is the Emacs version.
|
||
|
||
If you want to print international characters, install the intlfonts
|
||
distribution. For this, create a directory called `fonts' under the
|
||
`emacs-XX.YY' top-level directory created by unpacking emacs.tgz,
|
||
chdir into the directory `emacs-XX.YY/fonts', and type this:
|
||
|
||
djtar -x intlfonts.tgz
|
||
|
||
To build and install Emacs, chdir to the `emacs-XX.YY' directory and
|
||
type these commands:
|
||
|
||
config msdos
|
||
make install
|
||
|
||
Running "config msdos" checks for several programs that are required
|
||
to configure and build Emacs; if one of those programs is not found,
|
||
CONFIG.BAT stops and prints an error message. If you have DJGPP
|
||
version 2.0 or 2.01, it will complain about a program called
|
||
DJECHO.EXE. These old versions of DJGPP shipped that program under
|
||
the name ECHO.EXE, so you can simply copy ECHO.EXE to DJECHO.EXE and
|
||
rerun CONFIG.BAT. If you have neither ECHO.EXE nor DJECHO.EXE, you
|
||
should be able to find them in your djdevNNN.zip archive (where NNN is
|
||
the DJGPP version number).
|
||
|
||
On Windows NT and Windows 2000/XP/Vista/7, running "config msdos"
|
||
might print an error message like "VDM has been already loaded". This
|
||
is because those systems have a program called `redir.exe' which is
|
||
incompatible with a program by the same name supplied with DJGPP,
|
||
which is used by config.bat. To resolve this, move the DJGPP's `bin'
|
||
subdirectory to the front of your PATH environment variable.
|
||
|
||
Windows Vista/7 has several bugs in its DPMI server related to memory
|
||
allocation: it fails DPMI resize memory block function, and it
|
||
arbitrarily limits the default amount of DPMI memory to 32MB. To work
|
||
around these bugs, first configure Emacs to use the `malloc' function
|
||
from the DJGPP library. To this end, run CONFIG.BAT with the
|
||
"--with-system-malloc" option:
|
||
|
||
config --with-system-malloc msdos
|
||
make install
|
||
|
||
In addition, for Windows Vista you'll need to install Service Pack 1
|
||
(SP1) or later and enlarge its DPMI memory limit by setting the value
|
||
of this Registry key:
|
||
|
||
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Wow\DpmiLimit
|
||
|
||
Create this key if it does not exist. The value is a DWORD; setting
|
||
it to 536870912 should let Emacs use up to 512MB of memory.
|
||
|
||
If you have other problems, either building Emacs or running the
|
||
produced binary, look in the file etc/PROBLEMS for some known problems
|
||
related to the DJGPP port (search for "MS-DOS").
|
||
|
||
To install the international fonts, chdir to the intlfonts-X.Y
|
||
directory created when you unpacked the intlfonts distribution (X.Y is
|
||
the version number of the fonts' distribution), and type the following
|
||
command:
|
||
|
||
make bdf INSTALLDIR=..
|
||
|
||
After Make finishes, you may remove the directory intlfonts-X.Y; the
|
||
fonts are installed into the fonts/bdf subdirectory of the top-level
|
||
Emacs directory, and that is where Emacs will look for them by
|
||
default.
|
||
|
||
Building Emacs creates executable files in the src and lib-src
|
||
directories. Installing the DJGPP port of Emacs moves these
|
||
executables to a sibling directory called bin. For example, if you
|
||
build in directory C:/emacs, installing moves the executables from
|
||
C:/emacs/src and C:/emacs/lib-src to the directory C:/emacs/bin, so
|
||
you can then delete the subdirectories C:/emacs/src and
|
||
C:/emacs/lib-src if you wish. The only subdirectories you need to
|
||
keep are bin, lisp, etc and info. (If you installed intlfonts, keep
|
||
the fonts directory and all its subdirectories as well.) The bin
|
||
subdirectory should be added to your PATH. The msdos subdirectory
|
||
includes a PIF and an icon file for Emacs which you might find useful
|
||
if you run Emacs under MS Windows.
|
||
|
||
Emacs on MSDOS finds the lisp, etc and info directories by looking in
|
||
../lisp, ../etc and ../info, starting from the directory where the
|
||
Emacs executable was run from. You can override this by setting the
|
||
environment variables EMACSDATA (for the location of `etc' directory),
|
||
EMACSLOADPATH (for the location of `lisp' directory) and INFOPATH (for
|
||
the location of the `info' directory).
|
||
|
||
Emacs features which require asynchronous subprocesses that depend on
|
||
multitasking do not work in the DJGPP port. Synchronous subprocesses
|
||
do work, so features such as compilation, grep, and Ispell run
|
||
synchronously, unlike on other platforms.
|
||
|
||
Version 2.0 of djgpp has two bugs that affect Emacs. We've included
|
||
corrected versions of two files from djgpp in the msdos subdirectory:
|
||
is_exec.c and sigaction.c. To work around the bugs, compile these
|
||
files and link them into temacs. Djgpp versions 2.01 and later have
|
||
these bugs fixed, so upgrade if you can before building Emacs.
