4.6 - Icons again - scaling issues ??

[Paul Griffith-2]

Greetings,

I have just built Xfce 4.6.1 from source and I am running into one nagging  
issue with icons. I am aware that Xfce v4.6  doesn't ship with any default  
icon theme and you have to install Tango, GNOME or the Industrial icon  
theme. I have done those things, but I have a few issue and I believe they  
are all interconnected.

1 - Thunar -If I view any part of a file system in icon view, I get  
generic icons (for most but not all the file types). When I switch to  
compact list icon see the correct icons for all file types.

2 - Desktop Settings - If I set the icon size larger than 32 I get generic  
icons, any size under 32 works fine but  as soon as the size is 33 or  
larger it switches to the generic icon.

3 - Xfce Settings Manager - Again some icons are missing!

If I switch the icon theme, I get the same results.

So what is the problem? I can only think of a underlying issue with a  
graphic library. I was able to view the svg files from the icon directory  
with rsvg-view, gimp and display.

Here is the strange thing if I view the same .svg files with ristretto I  
get a nothing, it is just blank!

Any clues or hints? I am off to use strace to see what calls ristretto is  
making to display the .svg files.

I am build Xfce 4.6.1 on CentOS 4.6

Thank You

More followup:

Running strace on ristretto output the following:

/cs/local/packages/xfce-4.6.1/libexec/thunar-vfs-pixbuf-thumbnailer-1:  
Unrecognized image file format.

Mhmh, maybe some lib (libxfcegui4 or thunar) isn't correctly built
against librsvg? Not sure but…

I've run across this, and I seem to recall that the solution lies in
running gdk-pixbuf-query-loaders

-RW

When I run gdk-pixbuf-query-loaders, it dumps a list of loaders, should it  
do more than that ?


/cs/local/packages/xfce-4.6.1/bin/gdk-pixbuf-query-loaders

g_module_open() failed for  
/cs/local/packages/xfce-4.6.1/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-jasper.so:  
/cs/local/packages/xfce-4.6.1/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-jasper.so:  
undefined symbol: jas_stream_rewind

....snip....

"/cs/local/packages/xfce-4.6.1/lib/gtk-2.0/2.10.0/loaders/svg_loader.so"

"image/svg+xml" "image/svg" "image/svg-xml" "image/vnd.adobe.svg+xml"  
"text/xml-svg" "image/svg+xml-compressed" ""
"svg" "svgz" "svg.gz" ""
" <svg" "*    " 100
" <!DOCTYPE svg" "*             " 100

I can confirm the undefined symbol!

# nm  
/cs/local/packages/xfce-4.6.1/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-jasper.so  
| grep jas_stream_rewind
         U jas_stream_rewind

I will recompile gtk+ without jasper support and report what I find.

Thanks
Paul

Redirect that into /etc/gtk-2.0/$host/gdk-pixbuf.loaders (where $host
is $(uname -m)-$distro-linux probably).

Yeah, you'll need to fix that first.

OK  I recompiled without jasper

:( Same results, no change! It works fine with png icons with the  
exception of just one icon!

Blah .... time to go home!

I will post more updates!

Time as forced me to use the png icons. I suspect that the issue lies  
somewhere between our  CentOS 4.6 libraries, our NFS hosted libraries and  
the newer libraries installed in a custom location.

Thanks for the suggestions.

Let me close this thread off once and for all. The issue was with the versions of pango/cairo/glib/gtk+/librsvg I had installed. I had to do a lot of trial and error to find the right versions. Not too old and too new :)


Thanks
