Bug 93967 – help is not displayed in app-office/dia.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Peter Volkov (RETIRED) 2005-05-25 10:11:40 UTC]

I have app-office/dia-0.94-r1 installed. 
 
When I try to open /usr/share/gnome/help/dia/C/dia.xml with yelp I can see the 
following error:  
failed to load external entity "/usr/share/gnome/help/dtd/docbookx.dtd"  
  
When I press F1 in dia same error in console.  
  
As a workaround I've created symlink: 
ln -s /usr/share/sgml/docbook/xml-dtd-4.3/ dtd 
so now I can see help. But this is definitely a bug. 
  

Reproducible: Always
Steps to Reproduce:
1. start help from dia's menu  
   
Actual Results:  
Error from yelp: Error opening selected document. Below is the text I can see 
in console: 
 
peter@camobap ~ $ dia

[Comment 1 Leonardo Boshell (RETIRED) 2005-05-25 20:55:23 UTC]

This looks like a problem with your XML catalogs. Please remove the symlink you
created and:

1. Make sure you have installed the DocBook 4.2 XML DTD:
  emerge -p =docbook-xml-dtd-4.2*

2. Make sure your catalogs under /etc/xml are valid. /etc/xml/catalog should
have a line like this one:

  <delegatePublic publicIdStartString="-//OASIS//DTD DocBook XML"
catalog="file:///etc/xml/docbook"/>

And /etc/xml/docbook should have a line like:

  <public publicId="-//OASIS//DTD DocBook XML V4.2//EN"
uri="file:///usr/share/sgml/docbook/xml-dtd-4.2/docbookx.dtd"/>

If this is not the case, make sure you have the DTD as described in (1) and have
run 'build-docbook-catalog' (although the ebuild should run this for you).

This may be related to the fact that you don't seem to have 'doc' in your USE
flags, which could lead to this kind of problems. Please let us know how it goes.

[Comment 2 Peter Volkov (RETIRED) 2005-05-26 06:04:17 UTC]

Thank you very much for your help.    
    
This is rather strange, but I did not have emerge -p =docbook-xml-dtd-4.2*   
installed:   
*  app-text/docbook-xml-dtd :   
        [   ] 4.1.2-r4 (4.1.2)   
        [  I] 4.1.2-r5 (4.1.2)   
        [   ] 4.2 (4.2)   
        [   ] 4.2-r1 (4.2)   
        [  I] 4.3 (4.3)   
   
I have only 4.1.2-r5 and 4.3 installed. And do not have 4.2-r1. dia do not have  
such dependency and USE="doc" does not affect dia's ebuild directly (dia does  
not have USE="doc" at all). But may be if you have doc in USE variable, then  
some of dia's dependecies install this xml-dtd. Any way, I think dia should  
have this as a dependency (may be with "doc" USE flag). So IMHO this is a  
bug. :)  
 
And again thank you for your fast response. 

[Comment 3 Peter Volkov (RETIRED) 2005-05-26 06:08:57 UTC]

Sorry. I've missed my mouse cursor and "reassigned bug to owner of selected  
component".   
  
I'm trying to return assingnment back by myself. Leonardo, you may missed my 
answer in mail, but I answered above. 

[Comment 4 Leonardo Boshell (RETIRED) 2005-05-26 15:47:25 UTC]

Certainly, I will add that dependency if the problem is the one I described.

Did you emerge that DTD? Did it fix the problem?

[Comment 5 Peter Volkov (RETIRED) 2005-05-26 22:49:43 UTC]

Yes. I removed symlink, I mentioned about above. Then I did   
emerge =docbook-xml-dtd-4.2*   
  
After this help is displayed. I begin to think about this when I looked 
into /etc/xml/* files and did not found there nothing about dtd-4.2. Only 
dtd-4.3. But docbook-xml-dtd-4.3 is sloted (4.3), so it can be installed in 
parallel with docbook-xml-dtd-4.2 and does not appear to be an update to 
docbook-xml-dtd-4.2. Now help is working. 

[Comment 6 Leonardo Boshell (RETIRED) 2005-05-27 00:24:03 UTC]

Good, I've added the DTD as a dependency to dia now.

Thanks for your help.
