Description MATSUI Tetsushi 2007-08-25 06:51:00 UTC
The command clear failed because there is no $EPREFIX/usr/lib/libncursesw.5.dylib.

Reproducible: Always

Steps to Reproduce:
1. emerge ncurses-5.6-r2
2. run command clear on a terminal

Actual Results:  
% clear
dyld: Library not loaded: /Users/tetsushi/Gentoo/usr/lib/libncursesw.5.dylib
  Referenced from: /Users/tetsushi/Gentoo/usr/bin/clear
  Reason: image not found
Trace/BPT trap

Expected Results:  
clear the terminal screen

clear requires $EPREFIX/usr/lib/libncursesw.5.dylib:
tetsushi% otool -L /Users/tetsushi/Gentoo/usr/bin/clear
        /Users/tetsushi/Gentoo/usr/lib/libncursesw.5.dylib (compatibility version 5.0.0, current version 5.0.0)
        /Users/tetsushi/Gentoo/usr/lib/gcc/i686-apple-darwin8/4.0.1/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.9)

but there is no libncursesw.5.dylib in $EPREFIX/usr/lib:
% ls -l ~/Gentoo/usr/lib/libncurses*
-rw-r--r-- 1 tetsushi tetsushi 510988 Aug 22 11:49 /Users/tetsushi/Gentoo/usr/lib/libncurses++.a

It's in $EPREFIX/lib, on the other hand:
% ls -l ~/Gentoo/lib/libncurses*

Comment 1 Elias Pipping (RETIRED) gentoo-dev 2007-08-25 08:48:57 UTC
Yes, this is a known issue, ncurses 5.6 *is* broken in that regard. thanks for opening a bug, anyway, because that was only discussed privately and should have been made public, which it now has. ncurses 5.6 has been masked again yesterday (in r8873[1]) for that reason. please sync and downgrade.

Comment 2 Elias Pipping (RETIRED) gentoo-dev 2007-10-08 18:46:33 UTC
the bug doesn't need to be open because ncurses 5.6 is masked.
Comment 3 Fabian Groffen gentoo-dev 2007-10-08 18:49:00 UTC
we should still fix it, because everyone has 5.6 but us.
Comment 4 Elias Pipping (RETIRED) gentoo-dev 2007-11-11 12:34:47 UTC
Actual files that are installed:


so libncursesw.5.dylib *is* installed, rendering the summary of this bug incorrect. maybe it should go somewhere else, e.g. to /usr/lib, but it's certainly installed!

there's also two links for each:


none of the links is broken. what's important to note is that there's no libcurses or libcursesw - neither versioned nor unversioned.

the output of otool on the two files is correct as well. (tested on darwin9).

so what's the problem here? (I'm installing ncurses 5.6, I'll then re-emerge everything and see if something broke)
Comment 5 Elias Pipping (RETIRED) gentoo-dev 2007-11-11 12:49:52 UTC
actually, what's installed is this:

/lib/libcurses.dylib -> libncurses.5.dylib
/lib/libncurses.dylib -> libncurses.5.dylib
/lib/libncursesw.dylib -> libncursesw.5.dylib
/usr/lib/libcurses.a -> libncurses.a
/usr/lib/libcurses.dylib -> ../../lib/libcurses.dylib
/usr/lib/libcursesw.dylib -> ../../lib/libcursesw.dylib
/usr/lib/libform.dylib -> libform.5.dylib
/usr/lib/libformw.dylib -> libformw.5.dylib
/usr/lib/libmenu.dylib -> libmenu.5.dylib
/usr/lib/libmenuw.dylib -> libmenuw.5.dylib
/usr/lib/libncurses.dylib -> ../../lib/libncurses.dylib
/usr/lib/libncursesw.dylib -> ../../lib/libncursesw.dylib
/usr/lib/libpanel.dylib -> libpanel.5.dylib
/usr/lib/libpanelw.dylib -> libpanelw.5.dylib

( i only had a look at libncurses* before, my bad)

of the above, *one* is a dead link:

/usr/lib/libcursesw.dylib -> ../../lib/libcursesw.dylib

that link is present in ncurses 5.5 as well though (and is dead there as well)

(In reply to comment #4)

The problem is that you forget what the problem is, which you had surely known before(comment #2).
Though, I'm happy even if the problem suddenly disappears by a trick of leprechaun.
Comment 7 Elias Pipping (RETIRED) gentoo-dev 2007-11-11 15:28:42 UTC
I remember that ncurses 5.6 was broken. The newly added install_name_tool changes to portage appear to solve/work around the issue though, apparently. Can you produce a dyld error with ncurses 5.6? That'd certainly persuade me that something is broken here (I'm not trying to make a problem into no problem -- I'm just no longer seeing one)
Comment 8 MATSUI Tetsushi 2007-11-11 15:48:36 UTC
Now, I've just installed ncurses-5.6-r2 and see no problem.
clear is linked to lib/libncursesw.5.dylib correctly.

From my point of view as a user, it is just FIXED.
I have no more infos.

Thank you, anyway.
