You have more problems than just XIM if Canna support doesn't
compile.  Canna support has always gotten autodetected for me, except
when I was trying a beta version and had to point to the new version.

Nonexistent locale isn't a glibc bug.  It's an I18N support file bug
:-)

You're probably hosed by one of the versions of XFree86 that does not
support <X11/Xlocale.h>.  X makes provisions to work around the
absence of libc support, but it has to be compiled in to your Xlib.
What happens is that Xlocale simply uses a macro to alias setlocale to 
an internal Xlib routine _Xsetlocale.

XEmacs's configure process should detect this automatically.  Look in
src/config.h for `#define HAVE_X11_XLOCALE_H 1'.  If it's not there
(you should have a contrary #undef in that case), you need to get a
different version of X that supports X NLS.

    Klaus> Questions:

Lotsa people, although I personally haven't done it with 20.4.

    Klaus> * Does anyone know the status of glibc2 locale support
    Klaus>   (especially Japanese)?

In general, pretty good.  For the latter, Bu-Wha-Ha-Ha-Ha!  Wanna
write one?

First, start `kinput2 -xim +kinput +ximp -debug' in the foreground.
If it bitches about the debug, too bad; you don't have the debug
support.  Drop the `-debug' flag and add a `&'; no point in having a
TTY for debugging output if there isn't gonna be any.

Now start an instance of kterm with

	    XMODIFIERS="@example.com=kinput" LANG=ja_JP kterm -xim

and any other flags you like on your kterm.  You check it by doing
control-Mouse3 in the window to bring up the VT Options popup, and
looking for a check by Open Input Method.  If it's not there, select
that option.  You can probably also open XIM with Shift-Space, and
possibly [Kanji] depending on your resource database.
