compiling emacs using cygwin

compiling emacs using cygwin

[David R]

Hi,
My problem is that M-x agrep
M-x fgrep and all other greps produce the message as
 >  symbol's value as variable is void: grep-null-device

A google search told me that this was because emacs was badly installed.
I am using the win32 patch, the source of which seems to be included in 
the \nt directory of cvs release.

So I thought that doing a build would be as easy as building ruby.
I was very much wrong.  3 hours later.

I do cd /nt
./configure.bat
make bootstrap

it chugs away nicely for 3 minutes and then we get the error as follows

Re: compiling emacs using cygwin

I've found building Emacs on Windows to be difficult, although I've
written down what works on
http://www.emacswiki.org/cgi-bin/wiki/BuildingOnWindowsTableofContents.

You seem to be trying to build a "native Windows" binary, as opposed
to a Cygwin binary.  Is that right?  If so, I suggest you use MingW
and follow the instructions at
http://www.emacswiki.org/cgi-bin/wiki/BuildingCvsWThirtyTwoMingw -- it
works for me.  If that fails, you can always try getting a pre-built
binary from
http://prdownloads.sourceforge.net/ntemacs/ntemacs22-bin-20070102.exe?download
-- it's a few months old but the binaries at that site have always
worked fine for me.
               
If you want to build a Cygwin binary, install gcc 4 from source (yes,
that's a pain, but it works "out of the box") and then build Emacs
with the usual Unix-style "./configure; make" (i.e., use ./configure
instead of nt/configure.bat).

Are you using the Cygwin Make?  If so, please make sure your Make
version is one of those known to be compatible with the Emacs build
process, listed in nt/INSTALL.  Note that for Make 3.80 you will need
to uncomment 3 lines in nt/gmake.defs, as mentioned in nt/INSTALL.

I am not quite sure. I was attempting to use cygwin to compile it and I 
presumed that this will produce a native windows binary.
I have used MingW will reasonable success.  It produces an emacs from 
the nt version which runs on win XP but its appearance looks a bit 
shoddy, as thought it only uses 16 colours.  I presume that this is 
because I did not included any image support stuff like the link you 
mentioned does suggest.

This is a bit of a problem to install gcc4 from source because the setup 
utility only goes up to version 3.4.4
I have a few questions
      1.  How do I discover the version of my gcc without going to the 
setup utility?
      2.  Is there anywhere on the net which gives me a "hold your hand" 
guide to compiling gcc from source on cygwin.  I have found for linux 
but not unixy shells.
      3.  I have looked for a good introduction to unix via cygwin but 
have not found any useful stuff for the beginner.  Any suggestions?

Thanks

    I am not quite sure. 

Well, that would be a good thing to know :-)  The native Windows
binary and the Cygwin binary are significantly different -- for one
thing, the Cygwin binary runs as an X11 client; the native Windows
binary doesn't.  They treat file names differently, too, and there are
lots of other differences.
                         
    I was attempting to use cygwin to compile it and I presumed that
    this will produce a native windows binary.  

You can build both flavors with Cygwin; not surprisingly, the steps
you go through differ depending on which flavor you want.

I've never seen that; the version that I build from MinGW looks fine
to me (although I must admit I'm color-blind :-).

I doubt that's relevant.  I think "Image support stuff" allows Emacs
to display, e.g., jpeg images when you visit the .jpeg file, rather
than simply displaying the bytes in the file.  I doubt it has anything
to do with, say, the colors of the background, or fonts, or menus.

    This is a bit of a problem to install gcc4 from source because the
    setup utility only goes up to version 3.4.4

I think you misunderstood me.  I didn't mean "run the Cygwin setup
program and ask it to install the source for version 4 of gcc"; I
instead meant "Download 'gcc-core-4.1.2.tar.bz2' from
savannah.gnu.org, and unpack it with 'tar jxvf'".

    I have a few questions
         1.  How do I discover the version of my gcc without going to the
    setup utility?

Type "gcc --version".  The --version switch works for many programs,
not just gcc.

         2.  Is there anywhere on the net which gives me a "hold your
    hand" guide to compiling gcc from source on cygwin.  

Not specifically for Cygwin, that I know of, but the source includes a
directory named INSTALL full of instructions.  Here's my summary:

* create an empty directory and 'cd' to it
* run the 'configure' script from the source directory
* type 'make bootstrap'
* get coffee
* type 'make install'

    I have found for linux but not unixy shells.

I can't guess what you meant by that.

         3.  I have looked for a good introduction to unix via cygwin but
    have not found any useful stuff for the beginner.  Any suggestions?

Nope.  Cygwin is quirky, and using it well pretty much requires that
you have the Unix basics down.

If you don't mind spending lots of time experimenting and learning,
then keep on with your goal of building Emacs from source.  But if
you're in a hurry, I suggest you use the binaries at ntemacs.sf.net;
they're ready to run.

If you configure by running nt/configure.bat, then you will get a
native Windows binary of Emacs.  For the Cygwin build, you need to run
the `configure' shell script in the top-level directory of the Emacs
tree.  (However, note that to use the Cygwin build you will need to
install an X server.)

Where do you see that you only have 16 colors?  Are you perhaps
invoking Emacs as "emacs -nw"?  What do you see if you type "M-x
colors-display RET"?

This should only affect the tool-bar buttons, not the colors available
to Emacs for buffer text.

I have a confession to make.  I cannot find gcc-core-4.1.2 anywhere on 
the www

I have managed to achieve
svn -q checkout svn://gcc.gnu.org/svn/gcc/trunk gcc

which takes years and seems to download an entire hard disk
Can you give a cvs line which will simply grab this file for me?

Try again, and this time unpack the tarball into some directory whose
name doesn't contain a space.

yes this worked thanks
i now have gcc-4.1.2 on cygwin
still failed though

on nt version configure failed says it needs gcc-2.95 or later with 
minGW and the w32 API headers or msvc 2.x or later

on cygwin version the configure sucessfully creates a makefile, but the 
makefile fails
cannot load file ~/.abbrev_defs
it exists alright

As incidental additional failures

I tried building cygwin from source and the configure fails too

I tried building x server from source and the make fails after a long time

For X server
I have the necessary installed components except fileutils which I 
cannot find on the cygwin setup panel.

  The M-x colors-display was not recognised.

It doesn't mattter.  I was only compiling it so I could tell myself I 
had achieved something difficult.  I have a worked patched copy from 
that Swedish group who build a windows installer and add an extra 
customize w32 option to the options menu

Sorry, I meant "M-x list-colors-display RET".

That clearly shows you that Emacs supports much more than 16 colors.
So something else is at work here.

I think you are using an old version of igrep.el (which I wrote).
Version 2.84 from 1998-09-22 has:

(defvar igrep-null-device
   (cond ((boundp 'null-device) null-device) ; Emacs 20
	((boundp 'grep-null-device) grep-null-device)) ; Emacs 19
   "The system null device.")
