Bugzilla Bug 174453

app-editors/emacs-21.4-r4  USE="X Xaw3d nls -leim -lesstif -motif -nosendmail"

Currently, the relevant deps are the following:

Xaw3d? ( x11-libs/Xaw3d )
!Xaw3d? ( x11-libs/libXaw )

This leads to the following error when trying to build emacs without libXaw
already installed:

/var/tmp/portage/app-editors/emacs-21.4-r4/work/emacs-21.4/lwlib/lwlib.c:52:27:
error: X11/Xaw/Paned.h: No such file or directory

X11/Xaw/Paned.h is not provided by x11-libs/Xaw3d but by x11-libs/libXaw.

Thus, I suggest the following change:

Xaw3d? ( x11-libs/libXaw
         x11-libs/Xaw3d )

mkennedy seems to have found this, too, in 
http://bugs.gentoo.org/show_bug.cgi?id=128391#c3

Looks like libXaw is needed only at build-time:

$ scanelf -n /usr/bin/emacs-21
 TYPE   NEEDED FILE 
ET_EXEC libXaw3d.so.8,libXmu.so.6,libXt.so.6,libSM.so.6,libICE.so.6,

libgif.so.4,libXpm.so,libX11.so.6,libncurses.so.5,libc.so.6 /usr/bin/emacs-21

Could you try if the issue is fixed in emacs-21.4-r11 from the Emacs overlay?

Does the problem exist with emacs-cvs-22*, too?

Sorry, Ulrich, I'm not using the emacs-overlay. It should be easy enough to
test for this issue, though. Just "emerge -C libXaw" temporarily.

I've tested the following packages from the official tree as well and they're
affected, too:

- app-editors/emacs-cvs-22.0.96
- app-editors/emacs-cvs-22.0.97

I suspect the other packages might be affected as well but I haven't tested any
others.

Wulf, of course I had done this. ;-) I was able to reproduce the problem with
your USE flags and I it is now gone in -21.4-r11 (from Emacs overlay).

Hm, with those from the overlay I cannot reproduce the problem.

However, we expect to move the versions from the overlay to the official tree
during next week. So it would be nice to have an independent verification
before.

Ok, I did my tests using your overlay.

Broken with respect to libXaw:

- app-editors/emacs-cvs-22.0.97 
(USE="X Xaw3d -alsa -gif -gtk -gzip-el -hesiod -jpeg -lesstif -motif -png
-sound -source -spell -tiff -toolkit-scroll-bars -xpm")

- app-editors/emacs-cvs-22.0.9999-r9
(USE="X Xaw3d -alsa -gif -gtk -gzip-el -hesiod -jpeg -lesstif -motif -png
-sound -source -spell -tiff -toolkit-scroll-bars -xpm")

- app-editors/emacs-cvs-23.0.0-r5
(USE="X Xaw3d -alsa -gif -gtk -gzip-el -hesiod -jpeg -lesstif -motif -png
-sound -source -spell -tiff -toolkit-scroll-bars -xft -xpm")

Working:

- app-editors/emacs-21.4-r11

Any special reason you kept "!Xaw3d? ( x11-libs/libXaw )" in REDEPEND?

(In reply to comment #4)
> Ok, I did my tests using your overlay.

Thanks. I shall look into emacs-cvs-{22,23}* with your combination of USE
flags.

Good. ;-)

> Any special reason you kept "!Xaw3d? ( x11-libs/libXaw )" in REDEPEND?

Hm, I think you are right, that could be dropped. And probably
"Xaw3d? ( x11-libs/libXaw )" in DEPEND is sufficient, too.

Ebuild in overlay changed, can you test again (still -r11)?

emacs-cvs-{22,23}* updated and available in overlay for testing, too.

Even if this is working now, it is suspicious that libXaw is needed at build
time but not at runtime. It looks like the wrong include files are used, i.e.
the sources should include X11/Xaw3d/Paned.h instead of the missing
X11/Xaw/Paned.h (the two files being essentially identical, however).

BTW, Debian has seen this issue, too:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=365714
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=365597

Ulrich reported it upstream.

> Ulrich reported it upstream.
As discussed with philantrop before.

Revisions 22.0.98, 22.0.9999-r10, and 23.0.0-r6 moved to the Portage tree
today. Resolving as UPSTREAM since including the libXaw headers at build time
is a workaround only.

Thanks, Ulrich! 

I'd be grateful if you could update this bug once more if and when upstream
responds.Or just point me to their bugtracker (if they have one). :-)

 They don't have one, it hasn't hit the bug-list (is moderated), I will keep an
eye on the normal development list and check from time to time the bug list.

I've just re-sent my message to them, as it looks like the first one got lost.

It should appear in <http://lists.gnu.org/archive/html/emacs-pretest-bug/>
(updated twice per day) at some time.

The libXaw dependency has been removed, and the upstream patch included in:
emacs-21.4-r12
emacs-cvs-22.0.98
emacs-cvs-22.0.9999-r10
emacs-cvs-23.0.0-r6

Thank you! Greatly appreciated.

Reopening for proper resolution.
