Hi *,

the latest change on configure.in:

2007-01-26  Jan Djärv  <jan.h.d@swipnet.se>

	* configure.in: Add check for libXft.

breaks the build process for me (CVS Head on GNU/Linux with GTK+
frontend):

The new configure tests are successful:
  checking for xft >= 0.13.0... yes
  checking XFT_CFLAGS... -I/usr/X11R6/include -I/usr/include/freetype2
  checking XFT_LIBS... -L//lib -L/usr/X11R6/lib -lXft -lXrender -lX11 -lXext -lfontconfig -lfreetype -lz
  checking X11/Xft/Xft.h usability... yes
  checking X11/Xft/Xft.h presence... yes
  checking for X11/Xft/Xft.h... yes
  checking for XftFontOpen in -lXft... yes

But when building various libs seem to be missing when linking emacs:

  gcc -nostdlib `./prefix-args -Xlinker  -R/usr/X11R6/lib -z nocombreloc` -Wl,-znocombreloc -L/usr/X11R6/lib -o temacs pre-crt0.o /usr/lib/crt1.o /usr/lib/crti.o dispnew.o frame.o scroll.o xdisp.o xmenu.o window.o charset.o coding.o category.o ccl.o cm.o term.o xfaces.o xterm.o xfns.o xselect.o xrdb.o fontset.o xsmfns.o fringe.o image.o gtkutil.o emacs.o keyboard.o macros.o keymap.o sysdep.o buffer.o filelock.o insdel.o marker.o minibuf.o fileio.o dired.o filemode.o cmds.o casetab.o casefiddle.o indent.o search.o regex.o undo.o alloc.o data.o doc.o editfns.o callint.o eval.o floatfns.o fns.o print.o lread.o abbrev.o syntax.o unexelf.o bytecode.o process.o callproc.o region-cache.o sound.o atimer.o doprnt.o strftime.o intervals.o textprop.o composite.o md5.o    terminfo.o lastfile.o   vm-limit.o   mktime.o    -L/usr/X11R6/lib -L/usr/local/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0 -lpthread -lSM -lICE -ltiff -ljpeg -lpng -lz -lm -lungif -lXpm -L  -lncurses   -lm -lgcc -lc -lgcc /usr/lib/crtn.o

After removing the change and rebuilding configure building works

You have -L -lncurses in there.  What happens is when the preprocessor reads 
Makefile.c (generated from Makefile.in), your -L//lib ... is taken as a 
comment, and everything after // is removed, so you are left with -L.

Please do:

% pkg-config --libs xft

and if there is a // in there, check xft.pc (in /usr/lib/pkgconfig or 
/usr/X11R6/lib/pkgconfig usually) and see where //lib comes from.  My guess is 
that there is a variable substitution in xft.pc that does not work right.

//lib == /lib, see below...

You are right, the problem is not in your patch, but was triggered by
it on m system.

fontconfig.pc (one of the dependencies of xft.pc) on my system looks
like this:

  prefix=/usr
  exec_prefix=/
  libdir=${exec_prefix}/lib
  includedir=${prefix}/include

  Name: Fontconfig
  Description: Font configuration and customization library
  Version: 2.3.2
  Libs: -L${libdir} -lfontconfig
  Cflags: -I${includedir}

So yes, the library include directory is set to "//lib", in fact this
is a very common idiom in various situations when the prefix
installation path of software is set to "/".

In fact, it isn't wrong at all (though it touches a certain corner
case of the posix definition just by chance), the last paragraph in
the section "Pathname Resolution" (chapter "General Concepts") from
the posix standard states:

  A pathname consisting of a single slash shall resolve to the root
  directory of the process. A null pathname shall not be successfully
  resolved. A pathname that begins with two successive slashes may be
  interpreted in an implementation-defined manner, although more than
  two leading slashes shall be treated as a single slash.

On GNU Systems (and most unixoid systems I know), two leading slashes
are not interpreted in any special way, but like three and more
slashes: they are treated as one.

So the problem is, that the double slash is written unquoted to
Makefile.c where it gets interpreted as a comment.

This is IMO a bug.

When generating Makefile.c consecutive slashes hould either be reduced
to one or appropriately quoted.

Actually it was a bug in my patch, I should not use #define if a double slash 
may be present.  I briefly checked the other #define:s in Makefile.in and 
mostly the valuse comes from s/*.h or m/*.h, so we have control over these.

I've checked in a fix, please try it.

Thanks,

	Jan D.

Sorry, maybe I'm seriously missing something here, but I can't see
such a change by you, neither in CVS nor in the ChangeLog.

And, build still fails...  :-(

FWIW: my workaround for now looks like this:

I changed src/makefile.in, you have to rerun configure.

Ok, now I see your change.

But I'm sorry to say: it doesn't fix anything.  Now Makefile.c
contains:

  XFT_LIBS=-L//lib -L/usr/X11R6/lib -lXft -lXrender -lX11 -lXext -lfontconfig -lfreetype -lz  

which has exactly the same problem...

How about the following fix, which not only removes the problem for
xft but for all packages using pkg-config:

Why is there a \+?  Should we not change // to / everywhere, i.e.
   s,//,/,g

?

Most sed:s out there don't support \+, it is a GNU extension.  We can't use 
that.  You would have to do ///*.
