In the latest cvs version under Ubuntu 8.04, I am getting:

Me too.  The culprit would likely be

## Construct a sed command file that operates on lines between
## ^ELCFILES and the next blank line.  Convert spaces between members
## of COMPILE_FIRST to "\|", and escape directory "/".  List the .elc
## files, exclude the members of COMPILE_FIRST, convert ^$(lisp) to a
## literal " $(lisp)", add trailing " \\\" to the end of every line
## (the last \ continues the line in sed, the other \\ result in a
## single \ at the end of the replacement text).  For the last line,
## just use a single "\", for sed.  Finally, run sed using the command
## so constructed and update Makefile.in.  chmod +w is for CVSREAD=1.
## Errors in final sed are non-fatal, since they have no effect on
## building Emacs.
update-elclist:
	echo "/^ELCFILES/,/^$$/c\\" > temp.sed
	echo "ELCFILES = \\\\\\" >> temp.sed
	exclude=`echo $(COMPILE_FIRST) | sed -e 's, ,\\\\|,g' -e 's,\/,\\\\/,g'`; \
	ls $(lisp)/*.elc $(lisp)/*/*.elc | sed -e "/$$exclude/d" -e "s|^$(lisp)|	\$$(lisp)|" -e 's/$$/ \\\\\\/' -e '$$ s/ \\\\//' >> temp.sed
	echo "" >> temp.sed
	-sed -f temp.sed $(lisp)/Makefile.in > temp-elcfiles || rm temp-elcfiles
	rm temp.sed
	chmod +w $(lisp)/Makefile.in
	mv -f temp-elcfiles $(lisp)/Makefile.in || echo "Maintainer warning: failed to update Makefile.in"


in lisp/Makefile.in.  In particular, "Finally, run sed using the command
so constructed and update Makefile.in." since the preceding recipe does
not actually construct a command, but just a part of it.

I am not sure what the real intent here is.

The problem is that the generated sed script is missing a line
continuation backslash.

The following patch fixes:

It works for me on several varieties of RHEL, and on Debian testing.

> The following patch fixes:

Not for me. Applying this patch, my generated Makefile.in ends up
containing:

ELCFILES = \\
         $(lisp)/abbrev.elc \

rather than

ELCFILES = \
         $(lisp)/abbrev.elc \

I guess it's something to do with sed and/or /bin/sh versions.

(It's not vital that this command work for everyone, though of course
that is what I would like.)

I thought that was C.P. Snow.

I think I see what's going on now. I'm guessing you have /bin/sh
pointing to zsh. zsh's echo behaves differently from bash's with
regards to these backslash escapes:

bash> echo "ELCFILES = \\\\\\"   ->    ELCFILES = \\\
zsh>  echo "ELCFILES = \\\\\\"   ->    ELCFILES = \\

Hmph.

The following ought to work for everyone. Blech.

(Yes, I know I should be using printf rather than echo, but it isn't
used anywhere else in the Emacs Makefiles, so I don't know if I'm
allowed to.)

espenhw@demokritos:~/src/emacs$ ls -l /bin/sh

ELCFILES = \\

So yes, the shell difference is the problem.

I can confirm that this works for me.

I have GNU/Linux Kubuntu 8.04 and bash:

$ echo $SHELL
/bin/bash

Running the above command from Makefile (make update-elcfiles) prints, 
in temp.sed,

ELCFILES = \\

Instead, running from command line

ELCFILES = \\\


There is a bug somewhere. Perhaps, in 'Hardy' ?


Cheers,
    Angelo.

It doesn't matter what you have $SHELL set to, it matters what /bin/sh
really is (it seems to be dash on Ubuntu). Anyway, it should be
working now if you cvs update.
