Incorrect devanagari rendering on Linux

Incorrect devanagari rendering on Linux

[Dheeraj Reddy]

Hello all

   I am trying to use Feb 13 checked out sources of emacs and trying to write 
some devanagari scripts using the devanagari-itrans input method.
The win32 build works correctly on my windows xp machine but on my x86-64 
Debian Linux box, it doesn't work correctly.

The Linux rendering looks like

While the correct windows rendering looks like

I am on Debian -unstable fwiw.

The devanagari script rendering on Emacs CVS is perfect. The problem
you're having is due to the complex text layout rendering support
excluded during compilation. Please check out Emacs bug# 1033[1], where
someone else posted a similar issue. So you need to compile your own
Emacs or request the maintainer to compile Emacs with CTL options.

On GNU/Linux system, Emacs must be compiled with libraries
m17n-lib and libotf (and m17n-db) for CTL.  Please install
those packages, or, if they are not available for your
system, install them from the source code available at:
    http://www.m17n.org/m17n-lib-en/download.html
    http://www.m17n.org/libotf/
and, re-build Emacs.

     but on my x86-64 
    Debian Linux box, it doesn't work correctly.

Please don't call it "Debian Linux".  You're talking about a version
of the GNU system, used with Linux as the kernel.  To call the whole
thing just "Linux" is to give the credit for our work to someone else
who started later and did less.  That's being unfair to us.

See http://www.gnu.org/gnu/linux-and-gnu.html and
http://www.gnu.org/gnu/gnu-linux-faq.html, plus
http://www.gnu.org/gnu/the-gnu-project.html for historical background.

    The Linux rendering looks like

Linux doesn't do rendering.  That is not part of its job.

    The Linux build is built using the following libraries

This build has nothing to do with Linux either.
(Some of the libraries in it are developed by the GNU Project.)

    The win32 build works correctly on my windows xp machine

In hacker terminology, calling something a "win" is a form of praise.
If you wish to praise Microsoft Windows, you're free to do so; but if you
don't, then you might want to think twice about using the term "win32".

Thank you Richard for correcting me. I shall refine my terminology to call my 
system a Debian GNU Linux system and try to avoid the phrase 'win32'.
Apologies due for any grief caused.

Time to fix my issue by following the suggestions by Ashish and Keichi san.

Beware also the Debian libotf package is currently outdated (0.9.4), too 
old to build emacs against (at least not without hassle).

Harshula, cc'd, recently offered to act as a new debian maintainer for 
the package, but in any case new packages haven't materialised as yet!

Thanks all,
   Works like a charm. I installed libotf-0.9.8 frmo the respective homepage.

Thank you.  That will increase our influence as we campaign for users'

FWIW, libotf 0.9.8 finally made it into debian unstable.

Yes, thanks to Harshula there for stepping up!

Debian Lenny did just ship with the old libotf, so still something 
people may need to keep an eye out for for a bit when emacs bug reports 
from debian users come in, obviously enough.
