How to build a smaller emacs

How to build a smaller emacs

[litchie]

Hi, All

I want to build a smaller emacs, I mean the executable emacs.exe.
Currently it is around 27M..

I hope to reduce it to a smaller size so as to hope it can start
faster.

Can somebody be kind enough to tell me how to do this?

Thanks
chaoji

Are you sure that it is the Emacs executable that is loading slowly,
and not things loaded from your .emacs? How quickly does emacs start
when you start it as "emacs -Q" from the command line?

Yes, it is fast now, since my .emacs is almost empty, not loading any
other packages.
However, I would be very glad if it can be as fast as notepad :)
I searched the web, but no result. Looks that people do not care about
this problem.

I had that concern when I was a beginner using emacs too.
That happens because you're used to close your editor after you make
some modifications to a file.
That is not how most emacs users use emacs. Instead you keep it
running for as long as your machine is on, and you can use a 'server'
to open files from Explorer (i presume you're using windows, since you
mentioned notepad)

Maybe you will gain some insight from this:

http://www.emacswiki.org/cgi-bin/wiki/EmacsClient

"EmacsClient allows one to open a file for editing in an already
running Emacs. Because it doesn't start a new Emacs instance at each
invocation, you can setup EmacsClient as the default editor ..."

Alternatively, I recently found a cool piece of software called qemacs
that is a "quick emacs", but it probably doesn't extend with lisp, so
you would be missing most of the cool functionality.

Hope this could help,

And I shall also mention that my best experience with emacs on windows
is with this package:

http://www.ourcomments.org/Emacs/EmacsW32.html

You'll get this EmacsClient working "out of the box". Then you just
need to associate files you want to edit with emacs to the
emacsclientw.exe program and it will be almost immediate.

And then, sooner or later, you'll also realize that you also don't
need explorer so much, because you got a bunch of modes to help you
quickly open your files from inside emacs (ido, recentf, anything,
ffap, etc)

Though I believe that works nicely (I have not tested) it talks about 
the old gnuserv/gnuclient. With Emacs 22 comes instead 
emacsserver/emacsclient.

You can try to build it w/o all the image libraries and w/o X11
support.  If that isn't enough you can save another few 100kB by linking
against some other (non GNU) libc (e.g. μlibc or dietlibc), but you may
need to tweak the sources a bit.

I have to confer with David; building --without-x produces a lean
executable (~7MB), if you have the discipline to work in console-dom.

Re: How to build a smaller emacs

[Ken Goldman]

I think your real question is: How do I get emacs to start faster?

If so, the standard solution is to run emacs as a server (e.g. gnuserv) and
only start the server once per session.  My emacs server process typically
runs for months at a time, so whether it takes 1 or 10 seconds to start
no longer
matters.

You mean, your executable file emacs.exe is 27MB?  It should be only
10MB (6MB if you strip off debugging info).

Could you please tell me how to do it? My system is winxp with MinGW.

Thanks in advance.

I find the strip utility and use --strip-all to get it down to 21MB.
It is still a bigger one than that you mentioned.

How did it get this large in the first place?  What compiler did you
use to build it?  If you didn't build it yourself, where did you
download the binary?

I didn't do anything special to build Emacs (with the MinGW port of
GCC), and the resulting binary emacs.exe is 10MB before stripping it.

I built it with MinGW. (i386-mingw-nt5.1.2600)

The emacs.exe from  ntemacs.sourceforge.net is also around 20MB.

My build is 11,4 MiB before stripping.

Configured with

  configure --with-gcc --no-cygwin --cflags -IC:/my/includes

and built with

  C:\emacs> gcc --version
  gcc (GCC) 3.4.5 (mingw special)

That's the CVS version; on my machine its size is 12MB.  I was talking
about Emacs 22.1, which is slightly smaller.

Which begs the question to chaoji: what version of Emacs were _you_
talking about?  Maybe we are comparing very different programs.

Sorry, you're right.

My 22.1 binary is 9,99 MiB (10.470.815 bytes).

Still, 20+ MiB is weird.

Is this faster than usual? Or will the unidirectionally rotating disk  
be a bottle-neck? Then it would be better to use a small RAM disk ...

EliZ,

I was talking about ntemacs23, the CVS head version.
And I have also tried emacs 22 just now, the result is 7MB, after
stripped.

To be more accurate:

 Directory of D:\Emacs22\bin
09/27/2007  11:56 AM         7,424,000 emacs.exe

 Directory of D:\software\ntemacs23\bin
09/26/2007  10:40 AM        21,391,938 emacs.exe

A better title for my post may be:
How to build a smaller emacs23?

Any suggestions would be appreciated.
thanks.

This looks more like GNU Emacs 23.0.0, i.e. the unicode-2 branch.


I presume that on MS Losedows the family of vc-*.el files is  
standard. Then you could open a C or C header file from the src  
directory and read the mode-line. It will tell you from which branch  
the file and the ready programme come.

It seems while building emacs, you have not built emacs with option "--
no-debug", for cvs branch "debug is on" default, you can check this in
file nt/configure.bat.

But I also build without --no-debug, and so is Juanma (because we
happen to debug Emacs quite often).  And we still get a much smaller

Is it really CVS HEAD, or is it the unicode-2 branch?

CVS HEAD gives me only 12MB, not 21MB.

Please let's try not to use "HEAD" but "trunk".
Every CVS branch has a HEAD: the trunk, the 22 branch, the unicode branch, ...

All I can say is I'm stumped.

What does "objdump -h emacs.exe" display?
