Okular building help request

[Jonathan Schultz]

Thanks Thomas,

I think I'm making some progress. When I tried your first patch, I found 
that rather than being undefined, the symbols were multiply defined. 
With a bit of experimentation I managed to get rid of this error (though 
perhaps not the underlying problem) with the following patch:

--- a/conf/settings.kcfgc
+++ b/conf/settings.kcfgc
@@ -4,7 +4,7 @@
  Inherits=SettingsCore
  Mutators=true
  Singleton=true
-Visibility=OKULARPART_EXPORT
+#Visibility=OKULARPART_EXPORT
  IncludeFiles=settings_core.h,okularpart_export.h
  SourceIncludeFiles=qdom.h,QStandardPaths
  MemberVariables=dpointer

I could then build and install okular successfully, but still can't run 
it as it fails to find/load the okularpart plugin. I did what I could 
with gdb, and found that the call to d->loader->load() on line 184 of 
kpluginloader.cpp fails. But the debugger refused to step into that 
function call, and at that point I gave up trying to work out where it 
is failing.

Can anyone help me with another pointer?

Thanks,
Jonathan
