Bug 107342 – ebuild request for gsdjvu

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Giacomo Graziosi 2005-09-26 16:47:50 UTC]

djvudigital (package app-text/djvu,
http://djvulibre.djvuzone.org/doc/man/djvudigital.html) requires gsdjvu
(http://djvulibre.djvuzone.org/gsdjvu.html) in order to convert pdf/ps to djvu
format.
Could you please provide and ebuild?

[Comment 1 Alexandre Buisse (RETIRED) 2005-10-07 16:45:50 UTC]

Hi,

there seems to be some licencing problems (according to the COPYING of gsdjvu),
so we'll wait for an answer of the upstream developers before providing an ebuild...

Regards,
Alexandre

ebuild for gsdjvu

I use this ebuid in my overlay portage and it works for me. The licence conflict, as stated by the FSF, is that the CPL used by gsdjvu states that if you sue AT&T for a patent infringment you loose the rigth to use the software. The gsdjvu software is otherwise free software, the problem is the GNU licence (stricter).

The ebuild adds a USE flag djvu for ghostscript, so to compile use:
USE=djvu emerge ghostscript

hums... i think i t is not conflicting, because we are distributing sources separately, but the licensing link should inclde both of them... opinions??

Alexandre, what exactly is preventing you from adding the ebuild?

The program is licensed under a free software license, the CPL. Some 
people would like it to be licensed under the GPL (so they can integrate 
it with ghostscript or djvulibre), but this process may take years. 

Meanwhile, many people would like to use, and/or hack on the code. If you 
include the ebuild, you'll make their lives easier.

Thanks!

Alexey

'ghostscript-esp-8.15.1_p20060430' modified to support djvu

Attached an ebuild for ghostscript-esp .  Uses 'djvu' use flag in nearly identical fashion as the previously attached ghostscript-gnu ebuild.

gsdjvu is a driver for ghostscript (2 actually and a bunch of scripts), it doesn't work without it.

Is there a chance for new ebuild because gs-esp 8.15.3 is in portage :)

thanks I added this to gs-esp. WIll add to other ghostscripts also when I get time to do that :)

djvudigital with the --words or --lines options fails with

ESP Ghostscript 815.04: Unrecoverable error, exit code 1
djvudigital: cannot locate file "ps2utf8.ps".
+--------------------------------------------------------------------+
| DjVuDigital relies on this file to extract text from postscript    |

+--------------------------------------------------------------------+

I've tried this with ghostscript-esp 8.15.3 and 8.15.4 ebuilds. Looking at the ebuild, the missing file is copied from the gsdjvu package to the working directory, but it seems it is never copied from there to the system, or at least I am missing that file. Can someone confirm this?

Also, can anyone confirm that gsdjvu actually works with newer ghostscripts, e.g. ghostscript-gpl-8.54? This version is patched with gsdjvu, but the gsdjvu README only mentions building against 8.15. I tried gs-gpl-8.54 and it builds fine with USE="djvu", but djvudigital simply segfaults every time.
