Re: [evince] Building libevince as a static library

[Richard Shann <richard shann virgin net>]

Hi, Hib

Since your helpful email I have been driven back from my attempt to link
the pdf backend statically into the evince widget - the poppler code
depends on too many libraries for me to get to the bottom of.

Before I give up altogether I thought I should try the .dll route again.
> From a different build of evince I have a libpdfdocument.dll built and I
tried placing it in the location that evince reported it was searching
for it. But I got the following pair of error messages:

(denemo.exe:2248): EvinceDocument-WARNING **: `D:\lib\evince\3\backends\libpdfdocument.dll': The specified 
module could not be found.  
(denemo.exe:2248): EvinceDocument-WARNING **: Cannot load backend
'pdfdocument' since file 'D:\lib\evince\3\backends\lib pdfdocument.dll'
cannot be read.

The file exists at the location specified, and as I understand it there
are no permissions on a windows file system that would prevent the file
being read.

I wonder if you or anyone else knows what is going on here, and if there
is out there some build of the evince library with pdf backend support
that we can use/follow.

Any help will be much appreciated as I think I reached the end of my
tether some while ago!
