Please send this along to <>.  I don't think this is going to be a simple distribution-level fix.  (I also note that we don't have --enable-widec in the ncurses ebuilds, so you must be using locally-built libs.)  When you send your  vim bug report, you can say that you're building vim-6.2.140 since that is the patchlevel of the -r5 ebuild.

Let me know when you've sent your bug report so I can resolve this bug as UPSTREAM.

I'm not using locally-built libs, but just tried to emerge vim after adding --enable-widec to
ncurses ebuild & ebuilt ncursesw :-)

I sent bug-report to <>.

Comment 4 Aron Griffis (RETIRED) gentoo-dev 2004-01-06 14:58:52 UTC
Great, thanks!  I hope we'll see a fix soon.  Of course, the quickest solution will be if you can fix it yourself and give the patch to Bram (via ;-)
Comment 5 Gour 2004-01-07 02:28:30 UTC

It's not the fix for solution but by following Bram's hint I've discovered that the cause of
the problem is very simple.

auto/config.log gives several instances like:

configure:6218: checking whether termcap.h contains ospeed
configure:6231: gcc -o conftest -Os -march=pentium3 -mfpmath=sse -msse -mmmx -fomit-frame-pointer -pipe -funroll-loops  -rdynamic  -rdynamic   -L/usr/local/lib conftest.c -lelf -lnsl   -lncurses 1>&5
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.3/../../../../i686-pc-linux-gnu/bin/ld: cannot find /lib/
collect2: ld returned 1 exit status
which means that the problem is simple - by compiling ncurses with --enable-widec, there is only ncursesw library and ncurses is missing :-)

Now, I don't know (and asked Bram) whether vim'c configure should ask for ncursesw or
there should be both ncurses & ncursesw installed simultaneously?

Comment 6 Mamoru KOMACHI (RETIRED) gentoo-dev 2004-01-07 05:23:59 UTC
Okay, so ncurses ebuild should be something like Attachment #16945 [details].
liquidx: could you revise it using unicode USE flag and commit?
app-editors/nvi also depends on ncurses built with --enable-widec,
so it will be useful if we can turn the option on using unicode USE flag.
Comment 7 Heinrich Wendel (RETIRED) gentoo-dev 2004-08-19 08:09:44 UTC
this problem doesn't occur with vim-6.3 and ncurses-5.4-r4
