[tex-live] Problem with xdvik and beamer files

[Jean-Pierre Demailly]

Hi:

Many thanks for creating xdvi/xdvik, I am still using it most of the time 
to view *.dvi files. I just tried the most recent version xdvik-22.87 on
a Debian sid x86_64 box.

I found that dvi files produced with the latex-beamer package are 
not displayed correctly when using 'xdvi' (many postscript specials are
left blank, especially titles, page headers, etc). Please find enclosed
a small test achive 'xdvi_check.tar.bz2' that shows the problem.

In fact the execvp call to 'gs' fails for such specials. As far as I have 
been able to trace things, the problem occurs at the very start with the line
   currentfile cvx execute
that comes from 'psgs.c' (see output below).

It's not a new problem, so maybe you are already aware of this - in fact, 
I have never seen any Linux dvi viewer that had been able to display 
correctly such dvi files, other than converting them first to 
postscript or pdf.

Besides this, I created some years ago a slightly modified version of
xdvik that compiles with an extended version of libxaw3d (enclosed in
the next message). The enclosed 'xdvik.patch' is to be applied with
xdvik-22.87. After installing libxaw3dxft (with './builstd plain' or
'./buildstd debian'), the toplevel script 'build-xdvi-xaw3dxft' should
build it. In my opinion the result is much nicer than with plain Xaw
or Xaw3d, as the new GUI can make use of anti-aliased fonts and UTF8
input anywhere - I even prefer it to the motif version. Notice that
libxaw3dxft-1.6.2d could in fact be made a drop-in replacement for
the most recent version libxaw3d-1.6.2 of libxaw3d (but it has not 
been made so at this point, libxaw3d will not get overwritten).

Best wishes,
Jean-Pierre Demailly
