Hi,
After 3 months without an emerge -u world, I finally did one, but had a problem.
It stalled half way ./configure, without any error, or warning, with the following output: | Code: | yogurt root # emerge world -u
Calculating world dependencies ...done!
>>> emerge (1 of 101) sys-devel/autoconf-2.54 to /
>>> md5 ;-) autoconf-2.54.tar.bz2
>>> md5 ;-) autoconf-2.13.tar.gz
>>> Unpacking source...

* Applying autoconf-2.13-configure.in-gentoo.diff... [ ok ]
* Applying autoconf-2.5-infopage-namechange.patch... [ ok ]

I also checked the cpu usage, but it was normal.
Thanks for any help,

Hi,
trying a emerge -u --deep world. It starts to compile other ebuilds first. Let's see if it solves the problem.

Hi again,
I think I found where the problem occurs.
The following are the last lines of the core tests section on config.log:
| Code: | configure:1792: checking for emacs
configure:1818: result: emacs
configure:1831: checking where .elc files should go
configure:1841: $EMACS -batch -q -eval '(while load-path (princ (concat (car load-path) "\n")) (setq load-path (cdr load-path)))' </dev/null >conftest.out |
and the EMACS variable from the Cache Variables section:
| Code: | | ac_cv_prog_EMACS=emacs |
I think that the script stalls at line 1841, so here goes a quote from configure:
| Code: | # If $EMACS isn't GNU Emacs or XEmacs, this can blow up pretty badly
# Some emacsen will start up in interactive mode, requiring C-x C-c to exit,
# which is non-obvious for non-emacs users.
# Redirecting /dev/null should help a bit; pity we can't detect "broken"
# emacsen earlier and avoid running this altogether.
{ (echo "$as_me:$LINENO: \$EMACS -batch -q -eval '(while load-path (princ (concat (car load-path) \"\\n\")) (setq load-path (cdr load-path)))' </dev/null >conftest.out") >&5
($EMACS -batch -q -eval '(while load-path (princ (concat (car load-path) "\n")) (setqload-path (cdr load-path)))' </dev/null >conftest.out) 2>&5
ac_status=$?
echo "$as_me:$LINENO: \$? = $ac_status" >&5
(exit $ac_status); }
am_cv_lispdir=`sed -n \
-e 's,/$,,' \
-e '/.*\/lib\/\(x\?emacs\/site-lisp\)$/{s,,${libdir}/\1,;p;q;}' \
-e '/.*\/share\/\(x\?emacs\/site-lisp\)$/{s,,${datadir}/\1,;p;q;}' \
conftest.out`
rm conftest.out
if test -z "$am_cv_lispdir"; then
am_cv_lispdir='${datadir}/emacs/site-lisp'
fi
fi |
(line 1841 starts where the comments end)
After realizing that the problem would be realated to emacs ou xemacs, I merged the latest version o xemacs, but still the problem doesn't go away.
I have the sense that I'm nearing the solution, but still don't know what to do.
I would be glad to receive any kind of suggestion,
Ricardo Cordeiro
PS - Thanks to darktux for giving me some hints.

Ahhhhhhhh! Finally a cause!
I have been playing with autoconf's configure script lately, and found out that I don't have emacs installed, but in replace I have xemacs. In some way the script finds that I have emacs installed, and sets $EMACS to emacs. The problem arises ahead when configure is searching for the correct .elc files paths...
| Code: | | $EMACS -batch -q -eval '(while load-path (princ (concat (car load-path) "\n")) (setq load-path (cdr load-path)))' </dev/null |
which stalls if $EMACS is set to emacs. However, if set to xemacs, it is returned a directory list, which I think is the desired output.
Ok. Found the cause, all that's left is the solution.

Ohh my! I'm the problem. 
I created a /usr/local/bin/emacs script:
| Code: | #!/bin/bash
xemacs -wm $* |
Once erased, the problem ceases to exist.
Now I know why aliases exist.
I'm really sorry for this useless thread!
Forgive me,
Ricardo Cordeiro
